Land Cover & Impervious: TCMA 2007 (5 class)

This is a 15-meter raster dataset of a land cover and impervious surface classification for 2013, level one classification with 5 classes. The classification was created using a combination of multitemporal Landsat 8 data and LiDAR data with Object-based image analysis. For urban or developed, a regression model relating the Landsat greenness variable to percent impervious was developed to estimate and map the percent impervious surface area at the pixel level.

Land Cover & Impervious: TCMA 2007 (15 class)

This is a 15-meter raster dataset of a land cover and impervious surface classification for 2013, level two classification with 15 classes. The classification was created using a combination of multitemporal Landsat 8 data and LiDAR data with Object-based image analysis. For urban or developed, a regression model relating the Landsat greenness variable to percent impervious was developed to estimate and map the percent impervious surface area at the pixel level.
