Spatial Statistical Analyst

Pubblicato: Martedì, 20 Maggio 2014 Scritto da Supergeo Italia

SuperGIS Spatial Statistical Analyst è l'estensione finalizzata all'impiego di metodi geostatistici nel GIS. Oltre all'esplorazione dei dati spaziali, l'esecuzione di query e la visualizzazione di dati ed informazioni delle features dispone di capacità statistiche di base e consente agli utenti di eseguire analisi geostatistica per ottenere una migliore comprensione circa la varianza e la relatività dei dati territoriali.




Basic spatial statistical analysis

  • Enables users to compile basic statistics on the sample data (point layer), including the sample count, average, maximum, minimum, quartile, variance, standard deviation, skewness coefficient, variance coefficient, kurtosis coefficient and so on.
  • Enables users to review the distribution interval based on Divide and Interval.
  • Enables users to review the data distribution via three types of charts: Quantile, XY Distribution and Trend.


Variogram and Krigings

  • Users can conduct covariance analysis and illustrate semivariograms.
  • Provides users with various models for model fitting, such as Spherical model, Exponential model and Gaussian model and so on.
  • Users can modify the parameters for Nugget, Sill and Range in the semivariogram.
  • Users can set up the parameters of searching direction by themselves, such as Angle direction, Angle tolerance, and Bandwidth, to analyze the variance of the data in different directions.
  • Various Krigings are provided:
Universal Kriging
Ordinary Kriging
Simple Kriging
Indicator Kriging
  • Cross validation is provided via the cross validation chart and the measured values, predicted values, and error values of the paired point data, through which the overall distribution of the estimated values can be reviewed.
  • Users can obtain a linear regression equation and a linear regression chart for the sample data via Cross Validation.


Layer management 

  • Spatial statistics analyst provides layer manager tools that allow the adjustment of range and interval of the result values.
  • Enables layer display configurations using Grid, Filled contour or Contour.
  • Exporting the raster results as image files is supported.
  • Display raster with/without Hillshade.
  • Enables users to configure the sunlight location.


Supported file format

  • Vector files in GEO (SuperGeo GEO Format) and Shapefile formats are supported.
