+

Decision improved

+

Choose which sites deserve a site survey, feasibility review, or budget first.

+
+
+

Why it is faster

+

+ Batch ranking and interactive filtering replace manual map checking, so the shortlist updates immediately as the user changes district, score, or area thresholds. +
