All thematic layers were integrated and analyzed in a GIS.
Landscape value is evaluated by using different thematic layers overlaid with GIS geoprocessing.
To identify vulnerability we used following thematic layers: land use/cover, vegetation, soil, geology and geomorphology in ArcGIS software.
Other thematic layers were extracted from satellite images, topographical map, and other collateral data sources, then weighed according to their influence in locating process.
The symbol-based information in the geomorphological maps can be digitally stored as a powerful database with thematic layers and attribute tables.
However, due to the complex nature of fuel characteristic a fuel map is considered one of the most difficult thematic layers to build up.
As a director, Dutt is known for his imaginative use of light and shade, his evocative imagery, and a striking ability to weave multiple thematic layers into his narratives.
Using satellite imagery and relevant field data, eight thematic layers (rainfall, land slope, drainage density, soil, lineament density, geology, proximity to surface water bodies and elevation) of the factors having significant influence on groundwater occurrence were prepared.
It also analyses conditions in relation to protecting and developing the rural region, highlighting the chief problems in water management, access to roads and environmental protection, while graphically presenting basic thematic layers crucial for assessment.
These thematic layers and their features were assigned suitable weights based on the conceptual frameworks of AHP, Catastrophe and Entropy techniques and then they were integrated in the GIS environment to generate an integrated raster layer depicting groundwater potential index of the study area.
Various thematic layers viz.
