Resource Abstract:
This data set provides land use and land cover (LULC) classification products at 100-m resolution for India at decadal intervals for 1985, 1995 and 2005. The data were derived from Landsat 4 and 5 Thematic Mapper (TM), Enhanced Thematic Mapper Plus (ETM+), and Multispectral (MSS) data, India Remote Sensing satellites (IRS) Resourcesat Linear Imaging Self-Scanning Sensor-1 or III (LISS-I, LISS-III) data, ground truth surveys, and visual interpretation. The data were classified according to the International Geosphere-Biosphere Programme (IGBP) classification scheme.

The 2005 satellite data were classified and a national map of land cover was produced. The 2005 satellite data were aggregated into 19 IGBP classes (Table 2) from the available 150 classes using hierarchical class merging approach and converted to a vector map using webGIS tool. The 2005 LULC vector map was overlaid on the satellite data (Landsat TM 2005) for three seasons, winter (January-March), pre-monsoon (April-June), and post-monsoon (mid-October to December) to identify cropland and fallow land (multiple cropping was not captured). Extensive ground truth data were collected using existing field transects with high-resolution satellite images. The errors and discrepancies were corrected using the ground truth data and ancillary information supplemented by existing maps (Roy et al., 2015).

Resource Classification Categories:
1- Deciduous Broadleaf Forest
2- Cropland
3- Built-up Land
4- Mixed Forest
5- Shrubland
6- Barren Land
7- Fallow Land
8- Wasteland
9- Water Bodies
10- Plantations
11- Aquaculture
12- Mangrove Forest
13- Salt Pan
14- Grassland
15- Evergreen Broadleaf Forest
16- Deciduous Needleleaf Forest
17- Permanent Wetlands
18- Snow & Ice
19- Evergreen Needleleaf Forest

Cropland. Temporarily cropped area followed by harvest and a bare soil period (e.g. single and multiple cropping systems). Note that perennial woody crops will be classified as either forest or shrubland, whichever is appropriate. Includes orchards. Different types of cropland based on seasons (e.g. kharif, rabi, zaid) were not subclassified

Reprocessing for MODIS-GLAM (250-meter) applications:
The 2005 India Landcover/Landuse file was resampled to a raster image with 250-meters spatial resolution for cropland data drilling on MODIS-GLAM. The processing steps follow:

Pixel values of 2 (cropland category) were set to a binary value of 1.
Above binary data set was resampled from 100 meters to 250-meters spatial resolution.
