The Land Cover Change Application summaries the trend how much and what land cover types has been changed between 1996 and 2011 within H-GAC region based on National Land Cover Data (NLCD). It allows search by counties and do direct comparison between 1996 and 2011 change by type of land cover.
The 2015 land cover dataset was produced by the Community and Environmental Planning GIS (CE GIS) at H-GAC for the purpose of having biannual basis land cover data product with a level of accuracy suitable for planning and research applications at the regional level.
The dataset was developed based on 2015 LandSat 8 Operational Land Imager (OLI) and the Thermal Infrared Sensor (TIRS) scenes of 30m resolution acquired from the USGS. Four scenes with 0-5% cloud cover were used to cover the entire area. Using supervised and unsupervised classification techniques in ENVI remote sensing package, the imageries were classified into 10 major land cover classes. Classification classes were determined based on the NOAA and NLCD land cover classification schemes. The output cell size is in 30m resolution.
2015 10 Class
H-GAC unveiled the 2008 land cover data set which maps the 15 counties that encompass the Clean Rivers Program's (CRP) assessment basins.
The 2008 land cover data set updates the 2002 land cover map and is available in three formats: an original 10 category classification and two reprocessed classifications which slightly modify the original map. The 10 category classification used in this land cover delineation follows the hierarchical classification scheme utilized by the National Land Cover Data (NLCD).
Due to accuracy limitations the land cover data is not to be used for regulatory, jurisdictional or local planning decision making without thorough field verification.

H-GAC's 2002 Land Cover data set classifies the region's landscape into nine land cover categories.
The Land Cover data is available in three formats: An original nine category classification, and two reprocessed classifications based on the original classification.
Due to accuracy limitations of the classification, this data is not to be used for regulatory or jurisdictional decision making without rigorous or intensive field verification efforts.
