{"contractVersion":"parcelops.connector.v1","name":"dod-installations","displayName":"DoD Military Installations and Ranges","description":"Where a property sits relative to Department of Defense installation, range, and training area boundaries, read from the DoD MIRTA layers with no key. Built for the two facts that are not common knowledge: which sites carry the Foreign Investment Risk Review Modernization Act designation that foreign-buyer land rules turn on, and which are reported closed or excess rather than active, which is the redevelopment inventory. Distance is measured to the nearest point of a boundary, never to a centroid, because the largest installations run past a million acres. Boundaries are unclassified public outlines that may generalize; proximity is context and never a noise, AICUZ, or easement determination.
