Disponible avec une licence Geostatistical Analyst.
Geostatistical Analyst vous permet de créer facilement une surface continue ou une carte à partir de mesures stockées dans une couche d'entités points, une couche raster ou à l'aide de centroïdes de polygones. Les points d'échantillonnage peuvent représenter des mesures telles que l'altitude, la profondeur de la nappe phréatique ou les niveaux de pollution. Geostatistical Analyst fournit un ensemble complet d'outils consacrés à la création de surfaces permettant de visualiser, d'analyser et de comprendre les phénomènes spatiaux.
| Toolsets | Description |
|---|---|
Tools to predict values at unmeasured locations. | |
Contains tools used to assist in the placement of new sampling sites. The Densify Sampling Network tool can also be used to determine which sampling sites are no longer required. | |
Tools in this toolset are used to perform geostatistical simulations and to assist in the analysis of the results. | |
Tools for pre- and postprocessing when developing interpolation models using the Geostatistical Analyst. | |
This toolset contains tools used to create, modify, export, and manipulate the properties of a geostatistical layer. |
Geostatistical Analyst toolbar
Geostatistical Analyst contains tools for exploratory spatial data analysis and a geostatistical wizard to lead you through the process of creating a statistically valid surface. These tools are not part of the geoprocessing tools; however, the results obtained from them can be used in the geoprocessing tools.
| Tool | Description |
|---|---|
Examines your data in different ways, allowing a view into the data before creating a surface so that you gain a deeper understanding of the phenomena you are investigating and make better decisions on issues relating to your data. | |
The Geostatistical Analyst wizard guides you through the process of creating a statistically valid surface. | |
Divides the original dataset into two parts: one part to be used to model the spatial structure and produce a surface, the other to be used to compare and validate the output surface. The Subset Features tool is a geoprocessing tool that can also be accessed from the Geostatistical Analyst toolbox. |
