Go to Data Management Tools > Raster > Raster Processing and double. You will see boundary, roads, protected_regions, water_polygons and water_polylines layers loaded in the Layers panel. In an open ArcGIS 9.3 project, access the Arc Toolbox by clicking the red toolbox button. Expand it and drag each of the 5 individual data layers to the map canvas. You can download a copy of the geopackage from the link below:īrowse to the downloaded assam.gpkg file in QGIS Browser. Geofabrik India shapefiles were downloaded, clipped to the state boundary and packaged in a single GeoPackage file. We will be using the OSM data layers for the state of Assam in India. The Tools list provides a selection of commonly used conditional and mathematical tools, allowing you to easily add them to the expression. Use the Rasters list to select the datasets and variables to use in the expression. Geofabrik provides daily updated shapefiles of OpenStreetMap datasets. The Raster Calculator tool allows you to create and execute a Map Algebra expression that will output a raster. OSM is a global database of freely available base map data. We will use vector data layers from OpenStreetMap (OSM). In this tutorial, we will identify the suitable areas for development, that are This tutorial goes through the typical workflow for performing a site-suitability analysis - converting source vector data to appropriate rasters, re-classify them and perform mathematical operations. In general, this is the preferred approach for site suitability. It also allows you to combine any number of input layers easily and assign different weights to each criteria. Working in the raster space gives you a ranking of the suitability - not just the best suited site. This method is ideal if you wanted to find a binary suitable/non-suitable answer and you are working with a handful of layers. You can do the overlay analysis on vector layers using geoprocessing tools such as buffer, dissolve, difference and intersection.
