| Abstract | National Land Cover Database (NLCD) 2016 Land Cover, produced by MRLC (Multi-Resolution Land Characteristics) Consortium. This dataset is part of the updated NLCD 2016 release. The NLCD provides nationwide data on land cover and land cover change at a 30m resolution with a 16-class legend based on a modified Anderson Level II classification system. NLCD 2016 offers 7 integrated epochs of land cover for years 2001, 2004, 2006, 2008, 2011, 2013, and 2016. Developed classes in these years are directly derived from and updated following the impervious surface cycle. Full metadata are included in the nlcd2016.img.xml file located in the same path as the maintenance format file. Other products in the 2016 release update previously released versions of landcover products for CONUS (NLCD 2001, NLCD 2006, NLCD 2011) and are not directly comparable to previous releases/versions. -- See more information. | |
| Known errors/qualifications | 1. Since new 2016 versions of NLCD products for all years have now been released, the decision was made to refrain from reprojecting this dataset into the County's standard NAD83 HARN projection. Since pixels were therefore not resampled, they do now represent the exact area on the ground that the original satellite sensor collected. 2. Some sections of the file metadata and areas on the MRLC website accessed through the "More Information" link incorrectly state that land cover products were released for 2003, rather than 2004. 3. The version of this layer used as the raster (small-scale) portion of the "Vegetation - National Land Cover Database - 2016" MapGuide layer has been reprojected to the normal NAD83 HARN projection for use on that platform. | |
