An Overview of SuperGIS Spatial Analyst Extension

 

 

SuperGIS Spatial Analyst, constructed on SuperGIS , is a set of tools for geoprocessing, enabling GIS users to create, analyze and query raster data. With this spatial analyst tool, users are able to perform spatial data from different aspect and method to obtain the required geospatial information quickly.

 

The various built-in spatial analysis algorithms and expressions can help users perform the complex spatial analyses with the easy-to-use interface. This spatial analysis tool includes the integration of feature class data and raster data , location analysis of spatial data, searching suitable location, analyzing service range of targets, query information across multiple data layers, statistics of raster layer and transforming feature class layer to raster layer.

 

After field surveying, how do you demonstrate and analyze the complicated datum that obtained? No matter hydrology, topography, land use analysis, population density analysis or pollution analysis, you can perform the spatial analysis to the sampling data surveyed in those categories. And integrate, analyze and demonstrate the complex and diversified data. Or you can get the topographic analysis result by analyzing and displaying elevation data. Thus, through the diversified analysis tools and simple manipulation in Spatial Analyst, users can better understand the features of spatial data and help make the proper and better policy.

 

The functions in this analyst are classified into different toolsets, and you can find out the required ones through table below.

 

Toolset

Description

Conditional

The Conditional tools allow you to set the conditions to filter the input raster and control the values of the output raster. The conditions can be set by query attributes or conditional statement.

Distance

Distance tools take the sample points as standard and calculate the distance, allocation and direction of each cell and its closest sample point.

Density

Density tools allow to analyze the known quantity of a specific phenomenon and to spread the predicted distribution to the entire plane based on the spatial connectivity of the location.

Interpolation

Interpolation tools allow users to estimate the related datum of other unknown regions with the spatial sample data.

Surface

Surface tools allow users to get the additional information such as isolines, slope, aspect through further analysis on surface elevation.

Hydrology

Hydrology tools help users model the surface runoff. Working with digital elevation model, users can get the water direction, accumulative flow rate of the surface runoff model with this analyst and run advanced applications(regional planning, agriculture, forestry).

Local

Local tools calculates based on the function concept that each cell value of the output raster is generated by the function of input value. When users are calculating local analysis, they can combine the input rasters, get the statistics value or set the conditional value for multiple inputs to get the output cell value.

Neighborhood

Neighborhood tools create output values for each cell location according to the location value and the values identified in a specified neighborhood.

Zonal

Zonal tools partition the input raster into zones based on successive, identical cell values or by quantifying the input geometry feature. Then perform statistics.

Generalization

Generalization tools allow to generalize and combine the unnecessary parts or over-complicated information through masks and algorithms.

Extraction

Extraction tools extract a subset of cells by cell value or spatial location, which is similar to clip function in raster layer.

Reclassify

Reclassify tools allows to classify the cells of different values into the same class to simplify or combine some classes; or reclassify cells based on sensitivity, priority with a uniform interval.

Raster Calculator

Raster Calculator tools allow users to do mathematic and logical operation to different raster layers as they are executing multiple tasks. Make the multiple raster layers into another one raster layer.
