LIMITATIONS OF WBGT: WBGT's most serious limitation is that environments at a given level of the index are more stressful when the evaporation of sweat is restricted (by high humidity or low air movement) than when evaporation is free. This campaign has considerable relevance to the prevention of heat illness in sport.
Crucial innovations were (1) replacing the temperature and humidity measurements with WBGT, which additionally responds to sun and wind, (2) using epidemiologic analyses of casualty records to identify hazardous levels of WBGT and vulnerable trainees, and (3) protecting the most vulnerable trainees by suspending drill at lower levels of WBGT, and by improving their heat tolerance in special conditioning platoons. New control measures introduced in 1956 further reduced heat illness and also lost fewer training hours. Control measures based on air temperature and humidity, and applied to all trainees alike, had proved effective but had entailed excessive compliance costs in the form of lost training time. HISTORY OF WBGT: WBGT was invented and first used during the 1950s as one element in a successful campaign to control serious outbreaks of heat illness in training camps of the United States Army and Marine Corps.
Wet-bulb globe temperature ( WBGT) is nowadays the most widely used index of heat stress, yet many users appear to be unaware of its history and its limitations. As far as other useless data it has forced on me, i will deal with that another time.Wet-bulb globe temperature ( WBGT)-its history and its limitations. I changed this setting to "white dot" and applied it, this cut down the airport icons to the real airports. Airport is the first icon in their replacement icon area, so it defaulted the the first one. I might have found the problem, GSAK added by default, the airport icon to all waypoints. This is just a bunch of unneeded advertising being shoved down out throats!

If I'm onlt showing my topo layer it's not too bad, but if I turn on the city map layer, my screen get so full of icons you can't see the roads! This is very frustrating. It appears that many of these poi's are included in the "City Nav. There must be 40 small airports out here in a 40 mile radius, and my GPS shows an icon for each, boo! I've also used map setup to try and control these, but to no avail. I loaded up several geocaches between my home and old home town, about 60 miles apart and with the geocache icons and all the misc POI icons, you can't hardly see the roads.

Garmin poi loader 2.5.4 how to#
I created the different folders, but am not sure how to get the separate files into these folders, any ideas? I read on another post about SD card tricks, and the maps load up quicker with a card reader, then put card back into GPS and reboot. I contains the maps and poi data together, how can I separate these? The file that comes offf my GPS is an "img" file. I used the poi loader to try and delete some of these, no good, it deleted everything. It doesn't appear that anyone has actually tried any of the data here, because when i looked up the data in my tiny town of 1750 people, it give me numbers and addresses of closed or non-existent places. Granted I can see the advantages of knowing where a gas station or really cool natural wonder is at, but I can use my cell phone or yellow pages to find most anything else. I have adjusted the "least to most" and decluttered it, but too many icons. After loading up several mapsets using mapinstall, all the POI's came with each set, loaded up my "find" page, with so many choices they overlap each other.
