Tax Parcels (Landowner Parcel Boundaries) - **What**: Legal property boundary polygons with ownership information from county assessor records. - **Source**: Aggregated from thousands of county assessor offices across the United States. - **Key features**: Property line polygons, owner names, mailing addresses, assessed values, acreage, parcel identification numbers (PIN), land use codes. - **Coverage**: Thousands of counties nationwide (expanding continuously). - **Use cases**: Property lines maps, land ownership maps, real estate platforms, agricultural land acquisition, solar/wind development, title research. - **URL**: https://landmapmagic.com/data/landowner-tax-parcels ### 7. State Boundaries - **What**: Polygon boundaries for all 50 U.S. states and DC with names, postal abbreviations, and FIPS codes. - **Tier**: Free (no paid plan required). - **URL**: https://landmapmagic.com/data/state-boundaries-api ### 8. County Boundaries & FIPS Codes - **What**: Polygon boundaries for 3,000+ U.S. counties and county-equivalents with FIPS codes, names, and state associations. - **Tier**: Free (no paid plan required). - **URL**: https://landmapmagic.com/data/county-fips-api ### 9. MCD Township Names (Minor Civil Divisions) - **What**: Named township boundaries for local government reference in Midwestern and Northeastern states. - **URL**: https://landmapmagic.com/data/mcd-township-names --- ## API Overview - **Format**: REST API returning GeoJSON (application/geo+json). - **Authentication**: API key passed as query parameter or header. - **Map integrations**: Works with Google Maps, Mapbox, MapLibre, Leaflet, ArcGIS, and any GeoJSON-compatible platform. - **Tile layers**: Pre-rendered vector and raster tiles available for instant map overlay rendering. - **Free tier**: State and county boundaries available free. Other layers require a paid plan. --- ## Pricing - **Monthly Subscription**: $65/user/month for full access to all data layers and unlimited report generation. - **Team Subscription**: Custom pricing for multi-user organizations. - **Free tier**: State boundaries, county boundaries, and FIPS code lookups at no cost (rate-limited). --- ## Who Uses LandMap Magic - Agricultural appraisers automating land mix breakdowns and soil map reports - Agtech companies building farm management, precision agriculture, and crop planning platforms - Real estate platforms integrating property boundaries and land data - Crop insurance companies verifying field boundaries and cropping history - Government agencies and conservation organizations analyzing land use - GIS developers building rural mapping and land information systems --- ## Key Differentiators 1. **Agricultural focus**: Purpose-built for ag and land data, not a generic mapping API. 2. **Single integration**: One API for PLSS + CLU + CDL + SSURGO + parcels + boundaries — no need to manage multiple data sources. 3. **Pre-processed data**: Data is cleaned, tiled, and optimized for fast map rendering. No need to download and process raw shapefiles or rasters. 4. **Authoritative sources**: All data sourced from USDA, BLM, NRCS, and county assessor offices. --- ## Frequently Asked Questions **Q: What mapping layers and data are available through the API?** A: LandMap Magic provides API access to PLSS boundaries, CLU field boundaries, crop data layers, SSURGO soil survey data, landowner tax parcels, state and county boundaries, and more. **Q: What development frameworks are supported?** A: LandMap Magic works with Google Maps, Mapbox, MapLibre, Leaflet, ArcGIS, and any platform that supports GeoJSON. We provide code examples in JavaScript, Python, and React. **Q: What is PLSS Section-Township-Range?** A: PLSS Section-Township-Range (S-T-R) is the standard system for identifying land locations in 30 U.S. states. A description like "Section 14, Township 83 North, Range 24 West" identifies a specific ~640-acre piece of land. **Q: What is the 2008 FSA CLU dataset?** A: The 2008 Common Land Unit (CLU) dataset is the last publicly released version of agricultural field boundaries from the USDA Farm Service Agency. Post-2008 CLU data is restricted by the 2008 Farm Bill (Section 1619). **Q: What is SSURGO?** A: SSURGO (Soil Survey Geographic Database) is the most detailed soil mapping from USDA NRCS. It contains soil type polygons with properties like texture, drainage, pH, and productivity indices (CSR2, CPI, PI). **Q: What is the Crop Data Layer (CDL)?** A: The CDL is an annual crop-specific land cover classification dataset from USDA NASS. It classifies every 30-meter pixel of U.S. agricultural land into specific crop types using satellite imagery. Available from 2008 to present. **Q: Can I build a property lines map with this API?** A: Yes. The tax parcel API returns property line polygons in GeoJSON format that you can overlay on satellite imagery from Google Maps, Mapbox, or other providers.
