Future Land Cover Scenarios
DRB2070 Version 2 represents a revised baseline and two alternative forecasts of urban land cover in the Delaware River Basin (DRB) out to the year 2070. Our collaborators at the USGS modeled land cover to 2070 using the Chesapeake Bay Land Change Model. A comparison of these two products will soon be available to review.
Our DRB2070 Version 2 baseline & alternative land cover scenario data are available in the following formats (updated 7/31/17):
- ArcGIS online application: https://arcg.is/1neLqS
- Data files for GIS professionals: proportion developed for NHDPlus catchments (2001, 2011, 2030, 2070) with ArcMap document (.mxd) for quick visualization of all three scenarios. Download zip file: http://data.centerforlanduse.org/CLUS_DRB2070_v2.4.zip
- Integration with Stream Reach Assessment Tool (coming soon!)
Let us know how you anticipate using our mapping and modeling tools!
High-Resolution Land Cover Data
The University of Vermont Spatial Analysis Lab is producing a high-resolution (1m x 1m) LiDAR-based land cover dataset for all 43 counties that cover the Delaware River Basin watershed. The basin-wide data (full mosaic) is available on PASDA, the Pennsylvania Geospatial Data Clearinghouse, and the data will soon be available by county:
- Basin-wide High-Resolution Land Cover– UVM SAL, 2016
- New York High-Resolution Land Cover, Delaware River Basin- UVM SAL, Coming Soon!
- New Jersey High-Resolution Land Cover, Delaware River Basin– UVM SAL, May 2017
- Pennsylvania High-Resolution Land Cover, Chesapeake Bay Watershed and Delaware River Basin, 2013– UVM SAL, September 2016
- Delaware High-Resolution Land Cover– UVM SAL, March 2016
- Pennsylvania Statewide High-Resolution Tree Canopy– UVM SAL 2015
Data is also available for the Delmarva peninsula through the Chesapeake Conservancy.
In 2017, we completed A Framework for Long-term Land Cover Change Monitoring in the Delaware River Basin. In this framework, we provide recommendations for monitoring LULC change through annual “hotspot” analysis, 3DEP program coordination, and interim and full updates to the high-resolution land cover product. We also recommend comparing and contrasting forecast data available from the SU-CLUS SLEUTH model (30m), CBLCM (30m), and LCMAP (250m) products and repeating scenario development on a 5-10 year timeframe. Finally, integration of these tools into water quality assessments provide an unprecedented opportunity to inform current and future assessments.
Delaware River Basin Maps
Our research analyst has created fantastic maps of our 43 county study area to guide DRB2070 workshop discussions. A large format (30″x57″), highly detailed map (scale 1:350,000) of our study area is available for $40. See the example below and contact us for more information!

PKC Cluster Map
We are a small and dedicated group of scientists that is concerned about water and land use dynamics. Together, we have more than 50 years of experience mapping, modeling, and monitoring land use and land cover change in the United States, Europe, and South America.
