Whether it's income data, or pollutant distribution, constructing a continuous surface of point data provides visual impact and offers many enhanced query and analysis options. Begin with your questions and raw data files in MapInfo. With the available information in place, Vertical Mapper calculates trends and relationships between points and generates a raster grid using a choice of mathematical estimation techniques. Each grid cell is assigned a value that is calculated from the point table itself or derived from some spatial characteristic of the data points such as spacing, density, or visual exposure.
Grids serve as an interpolated and smoothed representation of randomly scattered point data.
Multiple layers of gridded data can be mathematically overlain to explore and resolve complex relationships. Vertical Mapper's contour generator threads isolines through any grid file of numeric values to build polylines or polygons with attributes attached. And, unlike many other packages, contour polygons are created as MapInfo complex regions that can be used to query and select information from other data tables. Grid files are displayed on screen as raster images using thematic coloring, hill shading and color ramping techniques. Overlie additional layers of map information to create an effective presentation using Vertical Mapper's powerful graphic capabilities.
