Base Plan / Prototype v0.1 · draft

A scaled base plan
of your lot.

Find a San Diego County address, or zoom in and click parcel outlines to choose one lot or several: the base map area. The page then reads the building footprints and USGS lidar over them, draws a base plan at an engineering scale (lot lines with lengths, footprints, an area table) and builds a to-scale 3D model (each footprint as a flat-topped block, the open area on the lidar ground) for Material Studio.

Data: SanGIS assessor parcels (hosted by SANDAG), OpenStreetMap footprints (FEMA and ORNL USA Structures as a fallback), USGS 3DEP lidar (public copy on AWS), and optional USDA NAIP imagery. Everything runs in your browser. Limits: areas and heights are estimates from public data, not a measured takeoff; parcels are a tax-parcel reference, not a boundary survey; footprints are mapped outlines, not floor area; heights come from lidar that may be years old, and the lot and heights are suggestions until you confirm them. No yards, setbacks or zoning. Preliminary: not for construction or permit submittal.
