Land use and land cover (LULC) classification of the CAP LTER study area using 2010 Landsat imagery
Publication date: 2015-09-18

Abstract:
The land use and land cover (LULC) mapping generated from the 30 meter resolution Landsat TM5 is prepared for CAP LTER analyses. The series of products includes three levels LULC classifications, from coarser land-cover types to finer, hybrid LULC types, arranged in three thematic maps with contrasting numbers of LULC categories: (1) 12, (2) 15, and (3) 21. The percent of vegetation cover (vegetation fraction) in the residential area is provided. The image has a resampled spatial resolution of 15 meters due to the image classification procedure.

The land cover mapping methods were mainly based on the expert knowledge decision rule set and incorporated the GIS vector layer as auxiliary data. The classification rule was established on a hierarchical image object network, and the land use and land cover (LULC) types were classified at three levels accordingly. Image object segmentations and classification are based on their characteristics, such as spectral, spatial, contextual, and geometrical aspects. Classification results include three maps with: 12, 15, and 21 LULC categories.
land use land cover (LULC) categories for the map with 12 LULC categories (landsat_2010_12class) include:
- 0 = unclassified
- 1 = Water
- 2 = Riparian vegetation
- 3 = Active crop
- 4 = Cultivated grass/tree
- 5 = High_densed_mt_vege (high density desert vegetation)
- 6 = Mid_densed_mt_vege (mid density desert vegetation)
- 7 = Low_densed_mt_vege (low density desert vegetation)
- 8 = Undisturbed
- 9 = Soil (urban compact)
- 10 = Urban built up
- 11 = Inactive crop
- 12 = Canal
- 13 = Building
land use land cover (LULC) categories for the map with 15 LULC categories (landsat_2010_15class) include:
- 0 = unclassified

- 2 = Riparian vegetation
- 3 = Active crop
- 4 = Cultivated grass/tree
- 5 = High_densed_mt_vege (high density desert vegetation)
- 6 = Mid_densed_mt_vege (mid density desert vegetation)
- 7 = Low_densed_mt_vege (low density desert vegetation)
- 8 = Undisturbed

- 12 = Canal
- 13 = Building
- 14 = Mixed building and parking
- 15 = 0- 10% vegetation cover residential area
- 16 = 41%- 50% vegetation cover residential area
- 17 = 11%- 20% vegetation cover residential area
- 18 = 21%- 30% vegetation cover residential area
- 19 = 31%- 40% vegetation cover residential area
- 20 = 51%- 60% vegetation cover residential area
