Descriptions of this project

ArcGIS geoprocessing to select suitable locations by tool development with geoprocessing script

The object of this project: to make a tool with geoprocessing script to find the best site selection for his family at the city of West Lafayette of a new Purdue student


Procedure

1. Create a personal geodatabase to save or load all the involved data

2. Load all vector and raster data in geodatabase

3. Project all vector data and raster data (DEM in Lafayette)

4. Perform spatial analysis tools by selection criteria to find the best location


Contents of Geoprocessing Scripts

Script Project 4a: Create a personal geodatabase to save or load all the involved data

Script Project 4b: Load all vector and raster data in geodatabase and project all vector data and raster data (DEM in Lafayette)

Script Project 4c: Perform spatial analysis tools by selection criteria to find the best location


Selection criteria

Input all feature data (all streets, restaurants, CE building, schoolmap, and houses shape files) into geodatabase

Project all feature data on UTM zone 16N, NAD83 Project the elevation_lafayette raster data on UTM zone

16N, NAD83 Select US Highway 52 from all streets Buffer US Highway 52 within 1 mile from selected US

Highway 52 Buffer restaurants within 2 miles from restaurants Buffer 6 driving distance miles to the Civil Engineering

building Buffer 3 driving distance miles to school Select houses with 3 bedrooms and a price less than

$150,000 from geocoding house addresses


Selection criteria (features)

Clip all_streets_buffer and restaurants_buffer → clip1_out

Intersect civil_engineering_buffer and school_buffer → intersect_out

Clip clip1_out and intersect_out → clip2_out

Intersect clip2_out and houses_select → final_out
