GMS Training - Perth, AU - Recap

We just completed a training course in Perth, Australia from October 23-26. The course was a great success. Users from all over Australia came together to learn how to use GMS to solve their ground water modeling problems. We even had a user fly in from Japan.


Many thanks to our friends at SRIT (Geoff and Glenys Flight) for organizing the course.
SRIT also had a drawing for some prizes for our course attendees.


Rasters

A new image object type which we are calling a "raster" has been added with GMS 9.0. Rasters are essentially images with elevations - an image that includes a color value and a data value at each pixel. GMS uses the raster object type to support DEM files, and a large variety of DEM file types can be imported into GMS as rasters.



Rasters can be displayed as 2D images, with or without shadows, or as a 3D point cloud without shadows. Both options are very fast and memory efficient. Four different shaders, or color ramps, can be used to show  variations in elevation.

Rasters can be interpolated to all other GMS object types as well as to MODFLOW layer data (similar to 2D scatter points). They can be created inside GMS from 2D scatter points.

A wiki page has been created to document the raster interface in GMS and a new Raster tutorial will be available when GMS 9.0 is released.

Online Maps

"Online maps" are a new feature added at GMS 9.0. Online maps are free raster data (aerial photos, street maps, elevation data etc.) from sources such as ESRI and OpenStreetMap.org (other sources can be added via an Advanced button). If you have an internet connection, online maps can be displayed in the background in GMS and are updated automatically as you zoom in and out or pan the view. The imagery is automatically projected to the current display projection and displayed in real world coordinates. An online map can be exported and saved locally with your project.

Online maps provide an easy way to locate and start a new modeling project. For more information, see the wiki.

MNW2 - Multinode Well 2 Package

GMS version 8.3 has added support for the MNW2 package in MODFLOW. This package is an update to the MNW1 package. In addition to supporting the capabilities of the MNW1 package, the MNW2 package can also calculate additional head changes due to partial penetration affects, flow into a borehole through a seepage face, changes in well discharge related to changes in lift for a given pump, intraborehole flows with a pump intake located at any specified depth in the well, and improved capability to simulate nonvertical wells.

Take a look at the GMS learning center here for new tutorials with the MNW2 package.





GMS supports manually creating/editing MNW2 boundary conditions directly on the MODFLOW grid.

In addition, the conceptual modeling tools have been updated to support the MNW2 package.


 
 


GMS continues to add support for MODFLOW packages. Look for more packages in the near future. Happy modeling!

GMS Training, Nancy, France - Recap


From June 12-15, 2012, members of the GMS development team and Dr. Norman Jones taught a GMS training course in Nancy, France at the Institut National Polytechique de Lorraine.

Many thanks to Dr. Fabrice Golfier for helping to organize the class. Individuals from Europe and the Middle East were able to come together and learn about the most advanced groundwater modeling software available, GMS. Once again the course attendees commented on the many powerful features available in GMS and how they could use the software in their work. Thanks to all those who attended.
