![]() 8.1.1 updates the GMDEbinary file format so that the information linking orientations to their projected contacts is saved in the file. Once you convert them to a manual contact, changing the orientation no longer changes the contact. Using this, you can really fine tune the orientation so it yields the contact with the best fidelity to the imagery. This makes it particularly easy to change, say, one of the three points in a three point orientation and, when you record the change, the project contact is automatically reprojected. NEW Linked orientations and projected contact - Now when you change an orientation that was used to project a contact, the contact is automatically reprojected with the new orientation.Fixed: Duplicate contacts can now be edited separately from the original.Fixed: SVG files now can include contacts projected into the subsurface.If the window is less than 800 prixels a scroll bar will appear tot he right of the Data pane, allowing you to scroll it. NEW: The Minimum window height has been reduced to 640 pixels.Text also gets a shadow behind it to make it stand out better. NEW white outline around orientation symbols - This option, set in the Inspector Palette, will draw a thin white line around orientation symbols so you can have dark symbols stand out on a dark background.You can also download a step-by-step quick start guide to GMDE, although this same document is also included in the zip file with new distributions of GMDE. To get a feeling for how it works, you can download the Big Elk anticline project. ![]() SVG files for use in your favorite (modern) graphics program GMDE can project apparent dips onto the line of section. Because topo profiles can have as many bends in them as you want, in addition to making geologic cross sections, this is useful for constructing river profiles, etc. Construct topographic profiles along a line of section marked with the unit boundaries, just by clicking on the boundaries and entering an annotation.These digitized contacts can be used in digital down plunge projections and can be exported via. Digitize contacts in latitude, longitude, (and Eastings and Northings) and elevation using as many points as you want.Measure irregular line lengths (both map length and slope length) and areas.Calculate the map thickness of stratigraphic units using any two points, one on the base and one on the top of the bed.kml file for visualization in Google Earth using Tom Blenkinsop’s cool 3D symbols. The strikes and dips can be output to your favorite stereonet program or saved as. Use the mouse to drag along a strike line you type in the dip and the program automatically determines the latitude, longitude, elevation, and strike of the datum.Carry out three point problems to determine the orientation of stratigraphic units, faults, and other types of geologic contacts.7 you can give them the gridFloat DEM of the map you want them to interpret! If you are in the US or Canada, use the USGS or Canadian DEM servers which are government supported and currently have no download limits.There is no additional educational value to making each student digitize their own data. ![]()
