GWN-DTM's Unsurpassed Power
GWN-DTM processes all data at one time even for large projects - the software has been tested by processing over 500,000 spatial points in one batch. There is no need to
break the data into smaller sets, which saves you time and enables you to concentrate your efforts on the project at hand. You can further save time and effort by using the batch processing mode which allows you to process
multiple tasks off-line. With batch mode, the processing can be done, for example, overnight.
Maximum Flexibility with GWN-DTM
GWN-DTM has been designed with open architecture, i.e., the software can be
modified to suit your specific requirements. You can incorporate your own utilities and execute GWN-DTM's commands in the sequence you need.
No Hidden Costs in GWN-DTM
When you purchase GWN-DTM, you will not have any additional costs. There is no need to buy different modules to perform specific tasks. With GWN-DTM you get it all in one
comprehensive package - from contouring to alignments, cross sections, earth works and slope analysis, it is all there.
Multi-platform
GWN-DTM is available on MicroStation and AutoCAD on multiple platforms. Whether your choice is PC, Sun or HP workstations, DEC Alpha, Windows or a combination of these, you
will find the same unequaled qualities of GWN-DTM working for you.
