The U.S. Geological Survey is in the process of implementing a new land cover and land change mapping and monitoring capability titled LCMAP – Land Change Monitoring, Assessment, and Projection. Basic elements of LCMAP include (1) a “reconditioning” of the Landsat archive into Analysis Ready Data to support time series analyses, (2) land cover mapping and land change monitoring, (3) land change assessment, (4) scenario-based land cover projections, and (5) the systems and services that enable these capabilities. The mapping and monitoring component of LCMAP is currently based on the Continuous Change Detection and Classification (CCDC) algorithm developed by Boston University researchers (Zhu, Z. and C. Woodcock, 2014, Continuous change detection and classification of land cover using all available Landsat data: Remote Sensing of Environment 144:152-171). Recent developments in LCMAP include using the recently released Landsat Analysis Ready Data and the application of CCDC to produce prototype annual land cover & cover change products for a 32-year period (1984-2015) across the coterminous U.S. To date, products covering six large areas have been evaluated. This presentation reviews the developments to-date, early results, lessons learned, and the next steps going forward for the LCMAP project.
