The MapCalc (Map Analysis Package Calculator) System

MapCalc is a comprehensive set of grid-based tools for advanced analysis and display of spatial information. The system has several basic forms—

üstand-alone Windows/NT/2000 version üintegrated modules for leading desktop GIS systems üvariety of application programs such as SoilRx for precision farming üa library of ActiveX controls and development environment for development partners

Import/export modules enable exchange of data with most vector/raster GIS data formats, databases and spreadsheets. Image registration, on-screen digitizing and GPS link provide for direct encoding of map. Display capabilities include 2-D grid and contour maps, 3-D surfaces with draped variables, vector overlay and a variety of summary reports, tables and charts. Integrated modules seamlessly link MapCalc’s advanced map analysis capabilities with the thematic mapping and geo-query tools of desktop mapping systems such as MapInfo and ArcView.

An intuitive graphical user interface provides direct access to individual operations through familiar dialog boxes with Window standard pull-down lists, command buttons, slider bars, text boxes and icons. A powerful macro builder enables users to easily generate, edit and reuse command sequences as GIS models. As commands are specified through the dialog box, a macro language automatically creates grammatically correct English sentences that are linked to a flowchart of the processing steps. Users simply interact with the flowchart to interpret and modify criteria for alternative conditions and scenarios.

The powerful modeling capabilities of MapCalc are divided into two broad classes—spatial statistics and spatial analysis. Spatial Statistics tools investigate statistical patterns and relationships among maps. They include…
