Map - OpenStreetMap is used by default (set Lat/Lon/Zoom/Span as needed); upload your own GeoTIFF or image if you need a different map, then click Load Map.
Sites - click "Add a PES", then click the map to place each one, or use "Add multiple PES" for a grid. Use "Add exposed site" (with a category) for anything nearby that isn't a magazine - an inhabited building, road, powerline, workshop, or POL facility - so only the AASTP-1 distance that actually applies to it gets checked.
Configure - set PES Type, NEQ, MCE, HD/SsD, CG, and SG per site; expand Construction details for barricading and other advanced options.
Analyze - click Run Analysis.
Results - review governing QD results and site compliance; colored arcs on the map show each category and overlapping arcs are conjoined.
