Suitability analysis is an evaluation of the suitability of a location or area for a certain use. based on how closely they adhere to criteria that you select and define.
The standards and conditions in the ArcGIS software environment are expressed in weight.
Inputs
Raster Vector
Examples of suitability analysis
Benefit from this Analysis
- Analysis for road networks .
It applies a lot of plans and follow up the planning processes.
- Analysis the sewage network .
- Finding the best sites for establishing projects.
In order to save time and effort and slove problems
The results are often displayed on a map that is used to highlight areas from high to low suitability.
Most important tools in Arc Toolbox used in Suitability Analysis
weight overlay
reclassify
Path distance
Slope
Polygon to Raster
EXP: Suitable Analysis to build a school
what are the criteria?
Flat Area Far from outher schools Close to recreational Area On a suitable land
The steps to do suitable analysis:
1- Inter the Inputs.
2- Standardization of cooordinates.
3- Start analysis .
