An effective tool for calculating and displaying the trends of data which vary continuously over geographic space. It provides a mechanism for sophisticated comparison and analysis of multiple map layers. By using grid technology to interpolate between points it is possible to analyse data without using artificial boundaries.

Using grids you can create stunning visual images by applying gradient colour palettes to the range of grid values. You can use Vertical Mapperä to visualise elevation, show the distribution of wealth across a city, optimise the location of broadcast towers, analyse health issues, model environmental information and much more.

Features and Benefits:

• Kriging – a geostatistical interpolation method for building grids with a minimal possible deviation.
• Enhanced speed with large files.
• Direct display of grids through raster drivers - no more generation of additional TIFF images (save disk space!).
• Powerful natural neighbour interpolators offer incredible surface control - grids automatically fill to a user defined boundary polygon.
• Wizard dialogs for interpolation routines.
• Quick access to functions through the grid manager.
• Supports classed grids (characters as opposed to numbers) using a new .grd grid format.
• Dictionary editor for classified grids allows easy reassignment of class names and colours.
• Analyse multiple layers (classified and numeric grid data) using easy-to-build expressions in the grid calculator.
• Support for z-unit types used in the telecommunications industry.
• Run interpolation on mapped or unmapped point data.
• Powerful graphing engine has a wide range of display options for professional graphs.
• Export grids to VRML format for 3D Fly-Through viewing in the standalone viewer or in your Internet browser.
• Gridview is enhanced with a dynamic 3D preview window and has the ability to render multiple grid layers in the same scene.
• Grid resizer allows any change to grid resolution.
• 2 way support for grids (.GRD) between Version 1 and 2.
• Region to grid generator provides 3D thematic maps or input for multi-layer grid analysis.
• Viewshed, point-to-point view analysis, and visual exposure analysis (multipoint to multipoint).
• Dynamic on/off relief shading and colour control of displayed grids.
• Trim grids to complex regions.
• Cluster function allows grid values to be reassigned to smaller "indexed" ranges
• Perform region analysis on entire tables of regions - each region in the table browser is updated with the statistical information from grid cells which lie within it.
• Enhanced legend generator.
• Extended on-line help.
• Limit the extent of voronoi diagrams to user defined boundaries.
• Change grid projections.
• New grid import capabilities.
• Customisable button pads.
• One button volume calculation.
• Interpolation settings are automatically recorded in grid for future reference (metadata).
• True overland distance calculations.
• Statistical filters (jumping or moving).
• Dynamically updated info tool.
• Grid splicer - merge, stamp or tile grids.
• Reclassification of numeric and character grids and exporting grids to .tif formats.
• Predictive analysis tool.
• Point density derivation.
• Correlation tool.
• Custom point estimation.
• GRC reclass.
