Trying to think next level/layer of preparedness. As I understand it, knowledge is power and information that leads to intelligence is essential for security. Looking for tips on doing an area study. I have Sam Culper's SHTF Neighborhood Security book and am working through it little by little. 
 Maps : USGS, ArcGis, openstreetmaps, TOPO, DeLorme, Google maps...
 Demographics : age, politics, income, etc.
 Terrain & Environment : Mountains, valley, desert, farmland, waterfront; rural, urban, suburban. 
 Other Tools : "Quarterback" armbands, Battle Board, Rite In The Rain notebooks, Field Notes notebooks, basic spiral notepad, clipboards, dry erase boards, polycarbonate clear sheets, etc.

Looking at relatively inexpensive and/or free or mostly open source info & resources. 
What books, Field Manuals, pdfs, maps, websites do people recommend? 
Obviously, SALT/SALUTE reports on intel and OPFOR movements. 
Also how are you implementing them? 
Binders, battle boards, ref cards to put in "quarterback" armbands...
 Something I came across that may prove helpful if your into this stuff,
