Spatial Analyst Extension
Spatial Analyst Extension
A spatial data processing tool that is structured on SuperGIS, providing desktop SuperGIS users to create, analyze and inquire raster data. Users can analyze spatial data using this tool in different perspectives and methods to quickly obtain the required geospatial information. |
|
Functions |
- Display surface spatial data
- Display spatial correlations
- Search for the the best location
- Enhance and display image data
|
|
Features
Spatial Polygon Analysis |
- Distance function is supported, and it contains the following analyses:
|
Straight line analyst: Contains three types of calculation methods, straight |
|
distance, allocation and direction. |
|
Cost weight analyst: Can generate cost distance chart, cost back link chart |
|
and cost allocation chart. |
|
Shortest path analyst |
|
Corridor analyst |
- Density function is supported, which is performed using either Simple or Kernel.
- Interpolation is supported, which includes Inverse Distance Weighted (IDW) and trend, allowing users to use the sample point data to estimate the data for a continuous surface.
|
Terrain Analysis |
- Viewshed function is supported, allowing users to analyze by either importing a known point or selecting a point on the map by mouse.
- Slope analysis is supported, where the display methods include degree, radian and percentage.
- Aspect analysis is supported.
- Curve analysis is supported, providing three analysis methods: Normal, Profile and Plan.
- Isopleth analysis is supported.
- Cut/Fill analysis is supported.
- Hillshade analysis is supported, allowing users to set up the azimuth and altitude.
- Cross Section illustration is supported.
|
Image Data Statistics and Processing |
- Re-sampling of raster layers is supported. It provides three sampling methods: Nearest Neighbor, Bilinear and Cubic.
- Ten statistics are provided for Cell Statistics, Zonal Statistics and Neighborhood Statistics: majority, minority, maximum, minimum, average, median, standard deviation, range, sum and variance.
- When using the Neighborhood Statistics, users can use rectangle, circle, annulus and wedge-shapes to select neighborhood extent.
- A calculator function is provided, allowing users to compile statistics on the raster data for logical and mathematical calculations.
- Users can perform image combination using the calculator function to obtain the results of image clipping.
- Raster to Vector data conversion is supported.
- Vector to Raster data conversion is supported.
- Image filter function is provided. It has many functions, including low-frequency filter, high-frequency filter, linear probing, edge enhancement, and so on.
- Image Reclassify function is supported.
- Legend settings for raster data are supported.
- Mask setting for raster data is supported.
|
Raster Data Toolset |
- Enables users to create raster data from point, polyline, polygon vector layers by four methods: constant, normal, random and text.
- Conversion of raster data to text files is supported.
- Various analysts are provided in the Toolset:
|
Distance Analyst |
|
Conditional Analyst |
|
Extract Analyst |
|
Local Analyst |
|
Neighborhood Analyst |
|
Zonal Analyst |
|
Generalize Analyst |
|
Math Calculate |
|
Support File Format |
- Vector files in GEO (SuperGeo GEO Format) and Shapefile formats are supported.
- Raster data in LAN and GeoTiff formats are supported.
