Discover provides a comprehensive set of surface gridding tools suitable for modelling, contouring, and visualizing any type of data from geochemical, geophysical, hydrogeological, meteorological, topographic, chemical, and environmental surveys.
|
|
Choose from the wide selection of gridding algorithms to create surface models from located point, line and region values. The resulting grid values can be queried and modified with a versatile collection of transformation tools. Compute curvature, slope, aspect, volumes, and other surface properties, or use the versatile grid calculator to derive values from user-defined expressions. |

| Visualize |
|
The Discover MapInfo GIS provides outstanding grid visualization options, and at a map-making standard.
- Map-quality contouring with sophisticated contour labelling controls
- Grid color modulation by linear distribution, histogram equalization, percentile and data breaks, or user-defined
- Dynamic sun-shading with single or dual light sources - ideal for detecting subtle trends in aeromagnetic grids
- Generate multiple profiles across multiple grids draped with polygon and polyline datasets - ideal for combined sectional analysis of, for example, geochemical grids, geological mapping and fault traces

| Very Large Grids |
|
With Discover you can confidently import, display, and modify massive grids, such as the multiple gigabyte grids used for continental SRTM data. The program architecture is designed to not just allow you open these very large grids, but also gives you instantaneous zoom and pan capability. You can also divide the grid into smaller tiles, or clip the grid around your area of interest. |

| Query |
|
Interrogate individual grid cells or select a group of cells that lie within a data range, or multiple data ranges, or by single slope angle, elevation, and aspect. |
