Full-screen map of 3.54 million Indiana parcels with zoning color overlays, aerial imagery, hydrology layers, and a slide-in panel that shows owner, value, lead score, and sales history on click. Parcels render as vector tiles at every zoom level.
The map at /app#/explorer opens full-screen with a street base map and an aerial imagery toggle. Pan, zoom, rotate, and pitch. Parcel boundaries render as vector tiles so they stay sharp at every zoom.
The sidebar lists every available layer grouped by category. Each layer has a toggle and an opacity slider. Layer configuration loads dynamically per county and city, zoning color schemes differ between Indianapolis, Fort Wayne, and Bloomington because each city defines its own zone codes.
Color-coded parcel fills by zone code. Each city loads its own zone palette from the API. Residential zones in one color family, commercial in another, industrial in a third. Click a zoned parcel to see the code and description.
Rivers, streams, canals, ditches, underground conduits, pipelines, and artificial paths from the USGS National Hydrography Dataset. Seven flowline types, each color-coded.
Lakes, ponds, reservoirs, swamps, marshes, playas, ice masses, and estuaries. Polygon fills with semi-transparent blue. Useful for recreational land prospecting and flood context.
100-year and 500-year flood plain boundaries from the National Flood Hazard Layer. Overlay shows which parcels fall inside a Special Flood Hazard Area.
Machine-generated building outlines for structure detection and lot coverage estimation. Available statewide.
Toggle satellite view from Google imagery. Useful for visual inspection of structures, lot conditions, and neighboring land use without leaving the platform.
Clicking any parcel polygon opens a slide-in panel on the right side with the key data for that property. The panel loads from GET /api/assessed/{parcelId}.
"View full report" opens the property detail page with all 10+ data sections. "Add to list" saves the parcel to any saved list. "Zoom closer" centers the map on the parcel at high zoom.
The map toolbar includes a 3D button that opens a fullscreen terrain viewer. Elevation data comes from the USGS Elevation Point Query Service. Useful for rural land parcels, development sites, and ag land where topography and drainage affect value.
The viewer samples elevation points across the current viewport, builds a terrain mesh, and drapes the aerial imagery over it. Not a full DEM, it queries the USGS API for point elevations and interpolates between them. Works best at zoom levels 12–16 on parcels with noticeable elevation change.
Ag land buyers checking drainage class and slope. Developers assessing grading costs before entitlement. Rural property specialists evaluating timber tract accessibility and water feature proximity. The terrain view supplements the USDA SSURGO soil data and USGS NHD hydrology layers available as 2D overlays.
