Being in Central TX, I can get to Mexico faster than any other US state, so Texas is sufficient for our vehicles plus a AAA US atlas. For folks not w/ a state or country closer than 4 hours away, probably makes sense to get multiple state Atlases.RSRnoreply@blogger.comtag:blogger.com,1999:blog-714028479313834812.post-68527042752144579352018-06-05T14:20:11.840-07:002018-06-05T14:20:11.840-07:00FalconView is an open source mapping aid that can ...FalconView is an open source mapping aid that can be made to print at whatever scale your large, wall-mounted maps display (assuming you have the same layer downloaded for FV). You can overlay icons representing whatever you want (cough, SIGACTS, cough), and then print out an 8.5x11 sheet covering most of your AO, with the last 12/24/72 hrs worth of events, depending on SOP. <br /><br />If you keep all the events in a spreadsheet, you can do map analysis of the various kinds of events, and with the printouts you can update the 'interesting' sections of the big map before briefings, patrols, whatever.

Depending on your area of operation, it can be useful to acquire OLDER versions of the same quadrangals so as to capture the topography omitted or overlaid by newer versions. Also, older maps often show details, for example on mines and quarries, that newer maps omit.<br /><br />Having both can be a help. Having a map board with a thin plexiglass surface allows easy planning on an eraseable surface that does not mark your map. 6 mil or 10 mil clear poly is a decent substituteHistorianhttp://www.libertyhollow.weebly.comnoreply@blogger.comtag:blogger.com,1999:blog-714028479313834812.post-32924000650337832112018-06-05T11:14:33.737-07:002018-06-05T11:14:33.737-07:00The complete set of USGS 7.5 minute maps for the U...The complete set of USGS 7.5 minute maps for the US is about 3.8 Terra-bytes.

I used them when I was chasing solar eclipses in places like Bolivia, Mongolia, Viet Nam and Venezuela. They're probably not all that useful for your reader's AO's as better products are available for local US use but the ONC's and TPC's cover just about everything outside the US. <br /><br />In the paragraph "... Because obviously, near the North pole, you could walk around the 89°99' latitudinal line on foot in a very short time. The entire longitudinal line at that spot is a circle a hair over 4 miles in circumference. Each step around it at that point is thus almost 11 minutes of longitude. At the equator, a minute of longitude is about 1.15 miles, so it would take over 25000 steps to go as far.)", the 89°99' should read 89°59' or maybe 89°59'59" N and the 25000 steps should be ~2500 steps to cover 1.15 miles at the equator. <br /><br />Otherwise for the above editing quibble you produce great work Aesop and I'm much obliged for your efforts.
