Freeware of Mapping; how to create and upload free maps/free custom maps/free POIs on GPS devices?

Freeware of Mapping; how to create and upload free maps/free custom maps/free POIs on GPS devices?

Here is the overview of Garmin Custom Maps from Garmin.

Free software:
  • Mobile Atlas Creator is an excellent open source (GPL) program which creates offline atlases for GPS handhelds and cell phone applications. Starting from v1.9 beta 2, it remove all map sources that are not basing on OpenStreetMap data because of conflicting with map providers. A few words about Custom Map Sources for MOBAC. You may download a copy of MOBAC 1.9 beta 1 here by BpACKer.
  • Terra Incognita is a mapping tool with a range of features and functions. You can use this program to download web source maps or local files maps and generate OziExplorer, Kmz, JNX, GPSdash or TrekBuddy calibrated map file.
  • ExifTool is a very powerful tool for editing meta information in image, audio, and video files. Exiftool GUI is a GUI for ExifTool. For geotagging a group of photos without any tracking information. ExifMixer is an another great GUI for ExifTool, it's good to change Exif in batch. 
  • GPXSee is a GPS log file viewer and analyzer that supports GPX, TCX, KML, FIT, IGC, NMEA and OziExplorer files.
  • Google Trail: a fascinating freeware converts Google,Yahoo Map, Openstreet Map, Cloudemate, or Bing maps into Garmin Custom Maps intuitively. It is simple and works like a charm, though it doesn't have as many features as Mobile Atlas Creator and OkMap.
  • GPSMapEdit is designed for visual authoring of GPS-maps in various cartographic formats
  • GPS Visualizer is a free online powerful GPS and mapping tool.
  • GPX Editor is a must-having good program for loading, modifying and saving your GPX 1.1 files.
  • ITN Converter is a great small freeware; it is a good one on both converting different formats and planning route simple and efficient.
  • GpsPrune is an application for viewing, editing and converting coordinate data from GPS systems. 
  • I use Picasa and Google Earth, or Lorc GPS Photo (the file size is much smaller). However, when I have tracking information downloaded from a GPS receiver, I usually use GeoSetter to geotag my photos taken along the trail. You can download GeoSetter Beta here.
  • OkMap is an interactive software which allows you to work on your computer screen with digital maps that you have either bought or scanned.It downloads and saving maps from Google Maps with automatic calibration. It generates compatible "Garmin Custom Maps" (kmz format). OkMap also supports JNX file format since version 9.7.0.
  • Viking is a free/open source program to manage GPS data. You can import and plot tracks and waypoints, show OpenStreetMap, Terraserver, Bing Aerial and other maps in it, download geocaches for an area on the map, make new tracks and waypoints, see real-time GPS position, etc.
  • GPSBable is good at converting waypoints, tracks, and routes between popular GPS receivers and mapping programs. I also install EasyGPS, a data transfer from your GPS receivers and computer, for a quick view of my downloaded waypoints, routes, and tracks.
  • How to create/plan route for a GPS Unit?You can use the BaseCamp, a powerful but big freeware from Garmin, to create routes, waypoints, and tracks. Here are some training videos.
  • MapSetToolkit generates TDB files for Mapsource and TDB files which will supports file TYP.
  • DNRGPS is built to transfer data between Garmin handheld GPS receivers and GIS software.

    A lunar eclipse occurs when the Moon passes behind the Earth so that the Earth blocks the Sun's rays from striking the Moon. This can occur only when the Sun, Earth, and Moon are aligned exactly, or very closely so, with the Earth in the middle. Hence, a lunar eclipse can only occur the night of a full moon. The type and length of an eclipse depend upon the Moon's location relative to its orbital nodes.

    Unlike a solar eclipse, which can only be viewed from a certain relatively small area of the world, a lunar eclipse may be viewed from anywhere on the night side of the Earth. A lunar eclipse lasts for a few hours, whereas a total solar eclipse lasts for only a few minutes at any given place, due to the smaller size of the moon's shadow.

    On April 25, 2011, the AIM-High study, a trial of high-dose extended-release niacin (Niaspan) added to a statin in 3000 patients with a history of cardiovascular disease, high triglyceride levels, and low levels of high-density lipoprotein (HDL), was halted 18 months early because niacin offered no additional benefits over statin alone.[1] When the news was announced on May 26, 2011, the news media had a blast with this "negative" finding. Misinterpretation of the sound bites from this study has caused significant confusion and apprehension among patients and healthcare providers. What are we to make out of this report?

    To fight obesity, even babies should exercise - Washington Times

    "LONDON (AP) - In a new campaign against obesity, the British government issued guidelines on Monday saying that children under the age of 5 - including those who can't even walk yet - should exercise every day.

    In its first such guidelines for children that young, the health department said kids under 5 who can walk should be physically active for at least three hours a day. Officials also said parents should reduce the amount of time such kids spend being sedentary while watching television or being strapped in a stroller.

    The three hours of activity should be spread throughout the day. Officials said the children's daily dose of exercise is likely to be met simply through playing but could also include activities such as walking to school.

    For babies who can't walk yet, the government said physical activity should be encouraged from birth, including infants playing on their stomachs or having swimming sessions with their parents. The government said children's individual physical and mental abilities should be considered when interpreting the advice.

    "It's vital that parents introduce children to fun and physically active pastimes to help prevent them becoming obese children, who are likely to become obese adults at risk of heart disease, diabetes and some cancers," Maura Gillespie, head of policy and advocacy at the British Heart Foundation, said in a statement."

    The art of scientific investigation (1957)


    By: Beveridge, W. I. B. (William Ian Beardmore)
     
    I read a Chinese version of this book (科学研究的艺术 or 科学之路) when I was a medical student. I cannot remember the exact content, but I thought it has affected my way of thinking so much in research. I'm always trying to find an English version to refresh my memory; it’s great to find it on the archive.org website for free.
    “In The Art of Scientific Investigation, originally published in 1950, W.I.B. Beveridge explores the development of the intuitive side in scientists. The author's object is to show how the minds of humans can best be harnessed to the processes of scientific discovery. This book therefore centers on the "human factor"; the individual scientist. The book reveals the basic principles and mental techniques that are common to most types of investigation. Professor Beveridge discusses great discoveries and quotes the experiences of numerous scientists.” – Amazon.com
    “The virtue of Mr. Breveridge’s book is that it is not dogmatic. A free and universal mind looks at scientific investigation as a creative art. This well written book deserves a wide audience. Manu of the author’s statements deserve to be quoted in every treatise on the psychology and practice of research.” –The New York Times
    “It is altogether gratifying when a scientific researcher undertakes to raise the mysterious certain of science... exposing his research activities and those of his fellow-scientists. The book is well worth reading.” –The Scientific Monthly
    “The author has a knack of putting into words what most experimenters sooner or later come to realize in a dim way, and it is extraordinarily interesting to see so much of the lore of research set down in print…The research worker - of whatever vintage - cannot do better than read this book, and, having read it, read it again.” – A. S. Parkes, F.R.S., in Nature

    Measured Smoking-Related Chemicals in NHANES

    Cotinine in Serum Cotinine file

    Cotinine: Tobacco use is the most important preventable cause of premature morbidity and mortality in the United States. The consequences of smoking and of using smokeless tobacco products are well known and include an increased risk for several types of cancer, emphysema, acute respiratory illness, cardiovascular disease, stroke, and various other disorders (U.S. DHHS, 2006). Persons exposed to secondhand tobacco smoke (environmental tobacco smoke [ETS]) may have adverse health effects that include lung cancer and coronary heart disease; maternal exposure during pregnancy can result in lower birth weight. Children exposed to ETS are at increased risk for sudden infant death syndrome, acute respiratory infections, ear problems, and exacerbated asthma (U.S. DHHS, 2004). The smoke produced by burning tobacco contains at least 250 chemicals that are toxic or carcinogenic, and more than 50 compounds present in ETS are known or reasonably anticipated to be human carcinogens (NTP, 2004). Source: http://www.cdc.gov/exposurereport/chemical_information.html

    2,5-Dimethylfuran:  2,5-Dimethylfuran is a volatile chemical found in tobacco smoke (Baggett et al., 1974) and in roasted coffee aroma (Wang et al., 1983). Exposure among the general population may occur through inhaling cigarette smoke and coffee aroma. 2,5-Dimethylfuran in blood and exhaled air has been used to determine smoking status (Ashley et al., 1996; Gordon et al., 2002; Perbellini et al., 2003). In addition, levels of 2,5-dimethylfuran found in blood provide a rough estimate of the number of cigarettes smoked per day (Ashley et al., 1995, 1996). After a person smokes cigarettes, 2,5-dimethylfuran is absorbed from the respiratory tract and then rapidly eliminated from the blood (Egle and Gochberg, 1979; Gordon et al., 2002). 2,5-Dimethylfuran is also a human urinary metabolite of n-hexane. Workers exposed to n-hexane will eliminate 2,5-dimethylfuran, along with other metabolites, in their urine (ATSDR, 2007; Iwata et al., 1983; Mutti et al., 1984; Perbellini et al., 1981).

    CDC - National Report on Human Exposure to Environmental Chemicals

    The Fourth National Report on Human Exposure to Environmental Chemicals 2009 and the Updated Tables, February 2011, together are the most comprehensive assessment of environmental chemical exposure in the U.S. population. Since 1999, CDC has measured 219 chemicals in people's blood or urine. The Fourth Report, 2009, includes the findings from national samples for 1999-2000, 2001-2002, and 2003-2004.
    The blood and urine samples were collected from participants in CDC's National Health and Nutrition Examination Survey (NHANES), which obtains and releases health-related data from a nationally representative sample in two-year cycles.

    Abstract: Small area estimation is important in survey analysis when domain (subpopulation) sample sizes are too small to provide adequate precision for direct domain estimators. Popular techniques for small area estimation use implicit or explicit statistical models to indirectly estimate the small area parameters of interest. Indirect estimation requires you to go beyond the survey data analysis methods that are available in the SAS/STAT® survey procedures. This paper describes the use of the MIXED, IML, and MCMC procedures to fit unit-level and area-level models, and to obtain small area predictions and the mean squared error of predictions. Hierarchical Bayes models are also discussed as extensions to the basic models.

    A top-down approach to diabetes

    The Lancet, Volume 377, Issue 9779, Page 1720, 21 May 2011
    On May 10, the UK's National Institute for Health and Clinical Excellence published its new guidance on the prevention of type 2 diabetes in adults. The guidance focuses on population-level and community-level interventions in high-risk groups and the general population. The groups at high risk include certain ethnic communities (south Asian, black, and Chinese) and lower socioeconomic groups (people in unskilled jobs), in addition to individuals who are obese or overweight and those who are not physically active. Of the ethnic communities in the UK at greater risk, people of south Asian origin are up to six times more likely to have the disease than white individuals. Also, people from lower socioeconomic groups are three and a half times more likely to develop ill health from the disease than groups with higher incomes.
    The guidance makes 11 recommendations, mostly on how commissioners and providers of public health services can best convey messages to promote behaviours that reduce diabetes and associated harms. The key, although unsurprising, recommendations are the promotion of healthy diets and physical activity. Promoting healthy eating is to include working with food manufacturers and caterers to reduce the calorie, saturated fat, and salt content of foods, and working with retailers on price structure, labelling, and promotion to encourage healthier diets. Promoting physical activity is to centre on planning regulations and transport policy. Measures relating to ethnic and socioeconomic groups include the provision of information in appropriate languages and through so-called community champions, and ensuring that all measures are affordable to individuals.
    Ultimately, the successful implementation of this guidance will need the cooperation of many parties, but the involvement of commercial partners must not be used to shift responsibility away from providers of public health. And success will also rely on engaging the communities that have been neglected so far. Although the recommendations might seem straightforward, they are long overdue and, if implemented, will powerfully affect public health beyond just diabetes.

    Helping your child master these simple rules of etiquette will get him noticed -- for all the right reasons. By David Lowry, Ph.D.Your child's rude 'tude isn't always intentional. Sometimes kids just don't realize it's impolite to interrupt, pick their nose, or loudly observe that the lady walking in front of them has a large behind. And in the hustle and bustle of daily life, busy moms and dads don't always have the time to focus on etiquette. But if you reinforce these 25 must-do manners, you'll raise a polite, kind, well-liked child.
    • Manner #1: When asking for something, say "Please."
    • Manner #2: When receiving something, say "Thank you." Related: Kid-Made Thank You Notes
    • Manner #3: Do not interrupt grown-ups who are speaking with each other unless there is an emergency. They will notice you and respond when they are finished talking.
    • Manner #4: If you do need to get somebody's attention right away, the phrase "excuse me" is the most polite way for you to enter the conversation.
    • Manner #5: When you have any doubt about doing something, ask permission first. It can save you from many hours of grief later.
    • Manner #6: The world is not interested in what you dislike. Keep negative opinions to yourself, or between you and your friends, and out of earshot of adults.
    • Manner #7: Do not comment on other people's physical characteristics unless, of course, it's to compliment them, which is always welcome. Related: Raise Polite Kids
    • Manner #8: When people ask you how you are, tell them and then ask them how they are.
    • Manner #9: When you have spent time at your friend's house, remember to thank his or her parents for having you over and for the good time you had.
    • Manner #10: Knock on closed doors -- and wait to see if there's a response -- before entering.
    • Manner #11: When you make a phone call, introduce yourself first and then ask if you can speak with the person you are calling.
    • Manner #12: Be appreciative and say "thank you" for any gift you receive. In the age of e-mail, a handwritten thank-you note can have a powerful effect.Related: Print and Color Cards for Birthdays, Thank-Yous and More!
    • Manner #13: Never use foul language in front of adults. Grown-ups already know all those words, and they find them boring and unpleasant.
    • Manner #14: Don't call people mean names.
    • Manner #15: Do not make fun of anyone for any reason. Teasing shows others you are weak, and ganging up on someone else is cruel. Related: Raise a Compassionate Kid
    • Manner #16: Even if a play or an assembly is boring, sit through it quietly and pretend that you are interested. The performers and presenters are doing their best.
    • Manner #17: If you bump into somebody, immediately say "Excuse me." Related: Quiz: What's Your Parenting Style?
    • Manner #18: Cover your mouth when you cough or sneeze, and don't pick your nose in public. Related: How to Handle Inappropriate Behavior
    • Manner #19: As you walk through a door, look to see if you can hold it open for someone else.
    • Manner #20: If you come across a parent, a teacher, or a neighbor working on something, ask if you can help. If they say "yes," do so -- you may learn something new.
    • Manner #21: When an adult asks you for a favor, do it without grumbling and with a smile. Related: Use this Table-Setting Map as a Guide
    • Manner #22: When someone helps you, say "thank you." That person will likely want to help you again. This is especially true with teachers!
    • Manner #23: Use eating utensils properly. If you are unsure how to do so, ask your parents to teach you or watch what adults do. Related: Mrs. McVeigh Weighs in on Proper Utensil Use and More!
    • Manner #24: Keep a napkin on your lap; use it to wipe your mouth when necessary.
    • Manner #25: Don't reach for things at the table; ask to have them passed.

    Salt, Salt, Salt

    There is discussion about salt and health during the last a few days. Some of them are thinking a re-think of CDC recommendation. I believe that salt is not our foe. The problem is that we take salt too much or too little. There are a few outlying persons who may need very low or very high level of salt consumption, but generally I feel the industries feed us too much salt, which is not good for our health. I have not read the salt recommendation and no comments on it, but I think that any recommendations on general population should be relaxing but not tight. A relaxing but doable recommendation is better than a radical but undoable/hurting recommendation.

    Here are two articles discussed the this issue: one from New York Times (my favorite layman source of health related topics), one from the USA Today:
    The original research article the reports talked is on JAMA: Fatal and Nonfatal Outcomes, Incidence of Hypertension, and Blood Pressure Changes in Relation to Urinary Sodium Excretion  (2011)

    There are other articles about salt and health, here are two:

    Thoughts

    We have all of these skills to do these analyses. I know the mission of Division/Branch, but sometimes I really miss the short-range specific targets of the Division/Branch. We may divide our time into to a few sections such as some for the major object/target of Branch, some for the interesting groups, and some for the personal creativity, etc. These activities have to be the object-orientated not the data- or survey-orientated; we can explore the issue from different angles using different resources.

      The CONSORT Statement Website
      CONSORT, which stands for Consolidated Standards of Reporting Trials, encompasses various initiatives developed by the CONSORT Group to alleviate the problems arising from inadequate reporting of randomized controlled trials (RCTs).
      The main product of CONSORT is the CONSORT Statement, which is an evidence-based, minimum set of recommendations for reporting RCTs. It offers a standard way for authors to prepare reports of trial findings, facilitating their complete and transparent reporting, and aiding their critical appraisal and interpretation.
      The CONSORT Statement comprises a 25-item checklist and a flow diagram, along with some brief descriptive text. The checklist items focus on reporting how the trial was designed, analyzed, and interpreted; the flow diagram displays the progress of all participants through the trial.

      Considered an evolving document, the CONSORT Statement is subject to periodic changes as new evidence emerges. This website contains the current definitive version of the CONSORT Statement and up-to-date information on extensions.

      Success Secrets - Keys to Tapping Your Own Potential
                Source: Fred Mayer

      Success is the business of trying to improve the things you do. Success is growing and developing. It's accepting bigger and greater challenges. And it begins with having a dream.
      "To find your dream, ask yourself what your passion or purpose is, and then pursue it," says Jeff Mayer, author of several books on succeeding in business and life. "After you have a well-defined purpose and know what you want to do, a master plan of action -- a business plan, if you will, for your future -- is essential. Finally, you must have persistence to stick with it and make it happen."

      What is success?

      Mr. Mayer has spent years studying the skills, talents and characteristics of successful people.
      "As you look at the list of talents and characteristics that follow, you'll realize you possess many of them yourself, and those that you lack, you can acquire," says Mayer.
      • Successful people have ambition. They want to accomplish something. "They have commitment, pride and self-discipline," he says. "They're willing to work hard and to go the extra mile."
      •  Successful people are strongly motivated toward achievement. "People who excel in life are those who produce results, not excuses," he says. "They take great satisfaction in accomplishing a task."
      •  Successful people are focused. They concentrate on their main goals and objectives, and they don't get sidetracked. "Successful people focus on those things that are most important day in and day out," he says. "As a result, they're not just busy, they're productive."
      •  Successful people learn how to get things done. They use their skills, talents, energies and knowledge to the fullest extent possible. They do the things that need to be done, not just the things they like to do.
      •  Successful people look for solutions to problems. "They are opportunity-minded," he says. "When they see opportunities, they take advantage of them."
      •  Successful people make decisions. They think about the issues and relevant facts, give them adequate deliberation and consideration, then make a decision. "Americans tend to be action-oriented, so the idea of spending work time thinking instead of working seems unproductive," says Mayer. "But thinking before you act or decide is essential."
      •  Successful people have the courage to admit they've made a mistake. "Don't waste a lot of time, energy, money and/or other resources trying to defend a mistake or bad decision," he says. "When you make a mistake, admit it, fix it and move on."
      •  Successful people are self-reliant. They have the skills, talents and training needed to be successful.
      •  Successful people have specific knowledge, training and/or skills and talents. "When they need information or skills they don't possess, they find someone who has them, then find a way to interact, partner and draw from the person's experience," Mayer says.
      •  Successful people work with and cooperate with other people. They have a positive, outgoing personality. They surround themselves with people who offer them help, support, and encouragement.
      •  Successful people are enthusiastic. They're excited by what they're doing, and their excitement is contagious. People want to work with them, do business with them and be with them. "It's easy to be enthusiastic if you like what you do," says Mayer. "And let's face it, life is too short not to like what you do for a living."
