Exporting 3D grids to shapefiles

A new feature in GMS 8.2 is the ability to export a 3D grid to a shapefile. The following figures show a MODFLOW model from the Lake package tutorial. The first image shows the model in GMS. The second shows the grid exported as a shapefile and read into ArcMap 10 with a background map, symbology, and transparency. GMS includes a projection file with the exported shapefile which causes it to be properly positioned when imported to ArcMap.



Training Adelaide Australia



Sustainable Resources Industry Training (SRIT) hosted a GMS training course in Adelaide, Australia from October 4-7. The course was a great success with attendees from Australia, New Zealand, and the Philippines. Thank you to all who attended and to Geoff and Glenys Flight from SRIT for organizing the course.
