ExploStat contains tools for exploring spatial variability, ordinary Point Kriging, Irregular Block Kriging and other deterministic interpolation methods. Furthermore there is a method for iterative optimizing sample plans.
Its most important power is visualization of spatial data. For exploration of spatial data it offers linking the variogram and the histogram with points on the map. Selection tools are available to guide the user through large data sets. Plotting transects of interpolated surfaces creates the opportunity to evaluate the effect of interpolation parameters. An important feature is presentation and processing of drill core information. As a result ExploStat offers tools for mapping sediment layers from drill core data.
ExploStat handles points, lines, polygons and raster data. It offers editing of spatial data with the mouse. In fact, it is a GIS program. The vector data are stored as a set of line segments, an arc-node structure is not yet used. Several ASCII formats are supported for vector and raster data. Attribute data are read from ASCII-CSV tables and DBASE IV tables. Just as the most well known GIS-programs ExploStat create project files where information is stored about data sets and location of data sets on the computer. A example data set and it’s associated project file is available on the website of ExploStat. The topics in this manual will be described in an order that is defined by the menu items and speed buttons of ExploStat.
