  • How to Perform Spatial Analysis

    The big idea here is that you can begin applying spatial analysis right away even if you are new to GIS. The ultimate goal is to learn how to solve problems spatially. Several fundamental spatial analysis workflows form the heart of spatial analysis: spatial data exploration, modeling with GIS tools, and spatial problem solving.

  • 4-GIS data Analysis

    Types of spatial analysis (Volusia, 1997) and (Chou, 1997) include: Single layer operations are GIS procedures which correspond to attribute queries, spatial queries, and alternations of data that operate on a single data layer, Multiple-layer operations are useful for manipulation of spatial data on multiple data layers, Spatial modeling involves the construction of explanatory and predictive models for statistical testing, Point pattern analysis deals with the examination and evaluation of

    The polygons network analysis class stores the resultant service area polygons. As with other feature layers, its symbology can be accessed from the Layer Properties dialog box of the feature layer. When a new service area analysis layer is created, the Polygons class is empty. It is populated only when the analysis layer is solved.

  • Overview of Weighted Site Selection and Suitability Analysis

    How to Use Weighted Site Selection in GISWhen to Use Weighted Site Selection in GISWeighted Site Selection ExampleRelatedIn order to use weighted site selection there is a standard workflow that should be followed. This workflow usually begins with defining a problem or criteria such as locating some potential sites for a new ski resort. The next step is to gather data and create raster surfaces to be used in the analysis. This step is followed by reclassifying the layers, weighting them and then overlaying the output layers with background information such as a map of topography to see the best potential sites. Reclassification is important in weighted site selection because it is used to simplify the interpretation of raster data by changing a single input value into a new output value (ESRI). It can also be used to group ranges of cell values into a single value. For example you can assign a value of 1 to a set of values that range from 1-50 and 2 to values that range from 51-100. This simplifies weighted site selection because different types of raster data will have different values based on what...

    Digital terrain analysis, GIS can build three dimensional models, where the topography of a geographical location can be represented with an x, y, z data model known as Digital Terrain (or Elevation) Model (DTM/DEM). The x and y dimensions of a DTM represent the horizontal plane, and z represent spot heights for the respective x, y coordinates.

    Another type of spatial selection is point distance (which has line and polygon versions too), which identifies all the points in one layer that are within a specified distance of a selected point(s) in a different layer. Like any type of selection, you can perform analytical processes on those highlighted features or save them to a new layer.

  • Suitability analysis - GIS Wiki | The GIS Encyclopedia

    Suitability ModelingDecision AnalysisApplicationsToolsSee AlsoA suitability model typically answers the question, "Where is the best location?" — whether it involves finding the best location for a new road or pipeline, a new housing development, or a retail store. Often, a Multi Criteria Evaluation approach is required in order to answer this question. Multi-criteria evaluation is the the process by which a set of known project criteria are explored, ranked and/or weighted, in order to find the best outcome. For instance, a commercial developer building a new retail store may take into consideration distance to major highways and any competitors' stores, then combine the results with land use, population density, and consumer spending data.This information would be ranked based on its importance to the storesuccess. Some of the criteria might be absolutely essential, while others may not be so vital, though certainly of benefit. This data could then be weighted based on these rankings, allowing for the vital criteria to be met first. The d...
