🤖 AI & Developer Tweaking Cheatsheet

If an AI agent or developer is modifying this tool, follow these exact guidelines:

File	Component	What to Tweak	How to Modify
app.js	Default Map Center	Adjust starting latitude/longitude and zoom	Modify map.setView([lat, lon], zoomLevel) in initialization.
app.js	Vector Layer Styles	Change boundary colors, stroke weight, opacity	Update style: function(feature) in the GeoJSON loader.
atal_setu.json	Infrastructure Polygons	Add or update regional road/bridge coordinates	Append GeoJSON Feature objects to the features array.
sample_plots.csv	Land Parcel Data	Update valuation rates, zone classification	Add new rows following plot_id, survey_no, area_sqm, valuation.
