Completed Actions

2018 – 2020

  • Compared initial estimates of high-resolution LULC change for Delaware and Maryland with estimates from the National Land Cover Database.
  • Launched the development of a 2017/18 one-meter resolution LULC dataset with enhanced accuracy and additional classes and remap the watershed in 2013/14 to ensure consistency.
  • Launched the development of 1:2000-scale hyper-resolution hydrography data based on the best available LiDAR imagery.
  • Developed the Floodplain and Channel Evaluation Tool to assess floodplain and stream channel metrics for existing hydrography data.

2016 – 2017

  • Developed a 2013/14 one-meter resolution LULC dataset to inform the Phase 6 watershed model.
  • Developed future forecasts of land use change to account for growth in the Total Maximum Daily Load.
  • Worked with state agencies to develop alternative future land use change forecasts (e.g., land policy best management practices) to value land conservation and land use planning actions in state Watershed Implementation Plans.
  • Identified hot spots of LULC change using the National Land Cover Database (NLCD) and compared them to high-resolution estimates of change.

2014 – 2015

  • Worked with the U.S. Forest Service and U.S. Geological Survey to develop the Land Image Analyst (LIA), easy-to-use software for classifying land cover and land cover change from aerial imagery.
  • Developed a stratified sampling protocol for estimating land conversion rates throughout the Bay watershed using the LIA.
