KML Boundary Mapper
Upload one or more KML files (any geometry) → rename/recolour layers → sample coordinates → export a cartographic PDF with a DMS coordinate grid, scale bar and per-layer legend
Designed & developed by Dr. Panda (User Manual)
Polygon, line, point and multi-geometry (MultiPolygon / MultiGeometry) all supported. Select several .kml files together (Ctrl / Shift click) — every geometry becomes its own colour-coded layer.
Colours saved inside the KML are used automatically. Layers without a colour get a default one. Tick/untick this before or after uploading.
Points generated at this spacing around each polygon ring and along each line. Leave blank to skip sampling — area/length are still measured, and point-type layers still show their own coordinates.
Tick the whole type above, or pick individual polygons / lines / points in the list. Only ticked layers get numbered points and appear in the coordinate list.
Changes the base layer on both the working map and the exported sheet.
Click a name to rename, the colour swatch to recolour, or the thickness box to adjust line/border weight. Tick a layer's checkbox to include it in a merge.
"Merge Ticked" combines the checked layers (same geometry type) into one multi-part layer. "Merge by Same Name" automatically groups and merges all layers that share an identical name and geometry type. Re-run "Process Layers" afterward to regenerate coordinate samples.
Auto-fit shrinks the legend text, adds columns and, if needed, makes the sheet taller so that no layer is cut off.
Needs internet. The state and district that contain your study area are fetched from OpenStreetMap (takes a few seconds).
Upload your Government of India / Survey of India boundary of India (KML or GeoJSON). The OpenStreetMap outline of Jammu & Kashmir and Ladakh differs from the official one, so it is not used unless you choose it.
KML or GeoJSON polygons. The state and district that contain your study area are found automatically and highlighted: India → State → District → study area.
