GRG Builder
Places a Gridded Reference Graphic (GRG) on the ATAK map. GRGs divide a geographic area into a labeled grid for coordinating operations.
Uses ATAK's built-in CustomGrid via GridLinesMapComponent — no
external plugin required for grid placement.
Rules
- ALWAYS call
build_grgto change spacing, size, or position — never assume a previous call is still active. Each call replaces the current grid. - When the operator asks to adjust an existing GRG (change spacing, resize, move), re-call
build_grgwith the updated parameters.
