Land Change Monitoring, Assessment, and Projection
Home
Land Change Monitoring, Assessment, and Projection (LCMAP) represents a new generation of land cover mapping and change monitoring from the U.S. Geological Survey’s Earth Resources Observation and Science (EROS) Center. LCMAP answers a need for higher quality results at greater frequency with additional land cover and change variables than previous efforts.
LCMAP Products
LCMAP offers a suite of 10 annual data products that depict land cover and spectral change in the conterminous United States. LCMAP Collection 1.1 has been released, with annual updates to follow.

Florida's Bone Valley is the source for about 60 percent of the phosphate mined for fertilizer in the U.S. LCMAP data offers insight on the frequent land cover changes that accompany the mining process.

Study of California Blue Oak Decline During Drought Draws Interest
A study published June 29, 2021 in the journal Frontiers in Climate, but “Hotter Drought Escalates Tree Cover Declines in Blue Oak Woodlands of California,” by four EROS scientists, already has been attracting attention.
LCMAP Releases Adds Data for 2018, 2019 with Release of Collection 1.1
The USGS Land Change Monitoring, Assessment, and Projection (LCMAP) initiative has released the first update to its Conterminous United States (CONUS) science products, adding two years of data to a satellite-derived product suite already-unparalleled in its temporal density.
USGS Landsat Satellites Enable Google to Portray Global Change
USGS Landsat satellite data and imagery are the key foundation for the newly released Google Earth 3D Timelapse tool. The upgraded Timelapse presents a global, zoomable time-lapse video of the planet from 1984 to 2020.

Hotter drought escalates tree cover declines in blue oak woodlands of California
California has, in recent years, become a hotspot of interannual climatic variability, recording devastating climate-related disturbances with severe effects on tree resources. Understanding the patterns of tree cover change associated with these events is vital for developing strategies to sustain critical habitats of endemic and threatened...
Dwomoh, Francis K; Brown, Jesslyn F.; Tollerud, Heather J.; Auch, Roger F. The effects of urban land cover dynamics on urban heat Island intensity and temporal trends
Assessments of surface urban heat island (UHI) have focused on using remote sensing and land cover data to quantify UHI intensity and spatial distribution within a certain time period by including land cover information. In this study, we implemented a prototype approach to characterize the spatiotemporal variations of UHI using time series of...
Xian, George Z.; Shi, Hua; Auch, Roger F.; Gallo, Kevin; Zhou, Qiang; Wu, Zhuoting; Kolian, Michael Comparison of simple averaging and latent class modeling to estimate the area of land cover in the presence of reference data variability
Estimates of the area or percent area of the land cover classes within a study region are often based on the reference land cover class labels assigned by analysts interpreting satellite imagery and other ancillary spatial data. Different analysts interpreting the same spatial unit will not always agree on the land cover class label that should be...
