Soil polygon data for part of Penobscot County, Maine, digitized from a 1963 USDA General Soil Map. The data was cross-matched with the State Soil Geographic Database (STATSGO) and prepared by NASA's Goddard Space Flight Center Biospheric Sciences Branch for the Forest Ecosystem Dynamics (FED) project. It was last updated in August 1995.
Use Cases
- Ecological modeling of vegetation-soil-energy interactions based on soil drainage and type polygons
- Resource management planning based on soil group delineations
- Cross-matching local soil data with broader STATSGO datasets for detailed analysis
Strengths
- Data is cross-matched with the State Soil Geographic Database (STATSGO), enabling linkage to detailed soil datasets
- Polygons were digitized, corrected, edge-matched, and appended from 6 original map sheets, suggesting a structured spatial dataset
Limitations
- Last updated 1995-08-31 23:59:59.999000; freshness should be verified
- Column-level documentation is absent; field semantics must be inferred after download
Provenance
- Source
- NASA Goddard Space Flight Center Biospheric Sciences Branch (formerly Earth Resources Branch) and associated University investigators
- Collection Method
