A recent post “Survive this: Six maps you should have for urban disaster evacuations” was very popular. Here’s four more maps.

Last week, we published a story on six basic maps to have when planning an urban evacuation. Apparently, a lot of you were interested – the post went viral, and got thousands of views.
Along with the views came feedback and suggestions.
Here are four other maps that may work in your areas:
From Weedhopper: Railroad map. Check with the department of transportation office for your state. Virginia will give you one for free…just email them in Richmond. (Get your own area by going here: http://fragis.fra.dot.gov/GISFRASafety/)
From ME: Sectional Charts or Aviation Maps. VFR maps are accurate and show visual points of reference such as railroad tracks, bodies of water, rivers, power lines,major roads, cities etc… You can actually download the whole maps free through the FAA, or buy them for about $8 each on-line. They show all the towers too.. which are great points of reference. (Here’s the link: https://skyvector.com/)
From Steve: Another source for FREE maps is the USGS. They have topo maps, rainfall maps, and plenty of others also. If you live in Texas then you can use University of Texas library for topos that you can customize for your area. (Check them out here: http://ngmdb.usgs.gov/maps/TopoView/)
Irrigation district maps: Every irrigation ditch probably has an access road that goes along it. In Central Oregon, this road can take you through a lot of isolated desert areas, where this may be the only road. For those of us in arid areas, these roads could prove to be an uncrowded route away from a population center. This is what my area irrigation map looks like: http://coid.org/files/2613/7047/2416/COI_shadedrelief2.pdf)
Disclaimer here: Don’t rely on a GPS or any electronic device as your only navigation tool. They are as reliable as the batteries in them. Get a good baseplate compass to go along with your map, and know how to use it.
