LAND COVER MAPPING TECHNICAL SPECS

Regional Land Cover

Regional Land Cover ImageCost-effective land cover planning and management can be achieved over large areas with remotely-sensed land cover mapping data. Land cover mapping classifies the current land conditions to a series of land cover categories. Comparing two or more similar land cover classifications can provide insight into change occurring on the landscape.

Sanborn offers a product based off of 30 meter imagery, which is appropriate for areas that are greater than 500 square miles. Sanborn’s Regional Land Cover product provides an accurate and cost-effective way to monitor changes in land cover for decision making. This product meets most land management activities for both state and federal governments that require broad scale data for research projects and planning by non-profit organizations.

APPLICATIONS

Regional planning, Land cover trend analysis, Watershed management, Forest analysis.

Technical Specifications

  • Based off ~30m imagery
  • Nominal scale 1:60:000
  • Appropriate for areas > 500 square miles
  • 18 classes
  • Overall 85% accuracy
  • Minimum mapping unit 2 acres
  • Delivered as a raster dataset (grid)

Options

  • Additional classes
  • Change analysis
  • Canopy and impervious percentage maps
  • Wildfire fuels map
  • Impervious surface model

Standard Land Cover

Standard Land Cover ImageSanborn has developed a medium resolution product based off of 5 meter imagery that leverages Regional Land Cover scale information yet refines the land cover boundaries. This cost effective product is a polygon based map with a five meter impervious dataset that allows statewide planning at a price and accuracy that previously was not possible.

This option is perfect for regional governments, states, and multi-state regions encompassing 200 – 100,000 square miles. It is easy to interpret and accurately maps smaller areas with more defined boundaries. The product also delivers a five meter impervious layer. Being polygon based with well defined boundaries, allowing easier identification of smaller features, and separate broken out impervious structures are the advantages of the Standard Land Cover product.

Applications

State and county planning, Stormwater management / modeling, Forest inventory analysis, Natural resource management, Urban planning.

Technical Specifications

  • Based off ~5m imagery
  • Nominal scale 1:24:000
  • Appropriate for areas > 200 square miles
  • 18 classes
  • Overall 85% accuracy
  • Minimum mapping unit 0.5 acre, impervious minimum, 0.25 acre
  • Deliverable as a raster or vector dataset (polygon)

Options

  • Additional classes
  • Change analysis
  • Urban ecosystem analysis
  • Increased accuracy
  • Impervious surface model

Enhanced Land Cover

Sanborn can collect new high-resolution multispectral imagery over an area of interest or use existing imagery to create land cover data sets for any community. Using proven semi-automated classification techniques we produce a precise, accurate, and detailed land cover map. This provides comprehensive land cover inventory, along with the means to monitor conditions over time through change detection analysis.

Digital data is classified by Sanborn into land cover classes required for planning. This solution is compatible with all of current GIS software products and integrates with existing workflows and GIS data layers.

Applications

Air quality management, Stormwater planning / modeling, Urban planning and zoning, Greenways planning, Urban forest management, Fire hazard assessment, Environmental assessments, Impervious or canopy model (app provided based on source imagery).
