Brief description
Crop maps represented in 11 spatial layers (ESRI GRIDS) which were classified from remotely sensed imagery (Landsat TM 5). The 11 layers are named with the month and year from which the image was captured as follows:jul11 (18/07/2011), may11 (15/05/2011), apr11 (13/04/2011), oct10 (3/10/2010), sep10 (1/09/2010), aug10 (16/08/2010), oct06 (24/10/2006), jul06 (20/07/2006), may06 (1/05/2006), oct99 (29/10/1999), aug99 (10/08/1999).
Lineage: Each Landsat image was atmospherically corrected then spectral samples were taken for known cover types (verified by ground truthing) and saved in a singature file. A supervised parallelpiped classification was then performed using ERDAS Imagine (v9.2). The classified layer was then reclassified into 41 classes within ArcGIS v9.3. There is a lookup table with the data (Crop_class_LUT) which lists the minor crop types (41 class values) as well as the major crop class grouping (9 cover types).
