This project involves the digitization and mapping of a cadastral survey area (Avalahalli) using high-resolution satellite imagery in Google Earth Pro. The work includes creating Level-3 (L3) classification features such as parcel boundaries, road networks, drainage lines, and point-based survey locations. Multiple vector layers were manually digitized, including polygons for land parcels, polylines for roads and boundaries, and point features for survey/reference locations (e.g., AV01, AV02). The process involved georeferencing, feature creation, layer organization, symbology and attribute tagging to maintain spatial accuracy and hierarchy. Different color codes were used to distinguish features such as administrative boundaries (red), internal parcel divisions (yellow), drainage/streams (cyan), and key landmarks (green). The final output is a structured, multi-layered cadastral map that supports land records management, urban planning, and spatial analysis at a detailed micro-level.
