Cogo:

Intelligent 2D & 3D Coordinate Geometry calculations to improve your design efficiency. It's Versatility will assist you with Title Surveys, Subdivision Design or Construction Site Design & Layout.

Terrain Modeling with Contours and Volumes. Interpolate Sections across any Model. Shade models by height and slope. 'Blend' models to create 'as-built' model simply.

Design Roads. whether rural, urban, or highways using either section templates or design strings. Also used for other regular structures such as airfields, channels, conveyors, railways etc.

Borehole logging just got a whole lot easier - simplified entry using your own templates means you get finished sooner, and Graphic Logs displayed as you go removes the errors.

Prolog comes supplied with a number of predefined templates. It also includes a template for the new Australian CoalLOg standard. Ensure your data is consistent with what the major Geological databases require.

Designed for the farmer or land contractor. Ezigrade offers a simple and effective solution for Agricultural Land Grading and Land levelling. Here are some program options.

Calculate a plane of best fit for a simple field.
Split the field into sections and calculate planes of best fit for each section
New - To reduce earthworks; partially grade a simple field by specifying grade tolerances. Those parts of the field within tolerance need minimal or no grading.
Add smoothing as well if required.
Split field into sections and partially grade each section.
Split field into sections and mix and match partially graded and planes of best fit for individual sections.

Simplified - recreational software for creating maps and contoured surfaces. Includes digitizing - both from sketch pad and onscreen. Export your map to "Google Earth". Create 3D views and drape bitmaps.

Designed for the field - with an inbuilt interface to GPS, Total Stations & Digital Levels, Ezifield brings your desktop jobs into the field on WindowsCE based pocket computers. Avoid costly mistakes - see exactly what you collect as you collect it.
