Description
GMDE Lite has been designed from the ground up with small phone-sized screens in mind although it also works very well on iPads and spectacularly on iPads with an Apple Pencil. We borrow the best from both GMDE Mobile and Stereonet Mobile and present that functionality in a clean, simple, map-centric interface. Data can be exchanged between GMDE Lite and Desktop, and imported from Stereonet Mobile, GIS programs, as well as uploaded or downloaded to/from StraboSpot.
Things GMDE Lite can do:
• Set a point of interest (POI) at your current location or anywhere on the map which is immediately tagged with location time and date and to which you can attach a photo and an extended description. You can email a POI, complete with photo, to a field partner, Advisor, etc.
• Annotate photos or make digital sketches attached to points of interest.
• Enter an orientation by any of five methods: (1) using the device orientation, (2) tapping three points on the map and having the device calculate the orientation, (3) sighting along the contact plane either in the strike or dip direction, (4) best fit plane to selected vertices on a path, or (5) type typing in the orientation at the location that you specify. You can project a contact temporarily as a check on the validity of the orientation; the projected contact can be converted to a regular contact.
• Read in and display POIs, orientations, and contacts on the map data from Stereonet Mobile or GMDE Desktop. Use copy and paste between devices registered to the same Apple ID using Apple HandOff technology.
• Enter contacts by tapping and dragging a path, by recording a GPS track, or by projecting a planar orientation across the landscape. Edit contacts by lassoing and deleting vertices or tapping and dragging individual vertices (works way better on an iPad with Apple Pencil than it does with your finger on a relatively tiny iPhone screen).
• Use the device camera/orientation as a rangefinder and plot a point of interest at the sighted location. Rapidly use the rangefinder to determine azimuth, inclination, slope, horizontal, and vertical distance to the sighted location.
• Display orientation data on an equal area, lower hemisphere projection which can be filtered by data type. Mean vectors, cylindrical best fits, poles to planes, and rose diagrams can be displayed.
• If you have a data connection, GMDE Lite can display your data on Apple Maps within the program as well as get point elevations from an online server.
• Use a variety of icons and colors to represent different types of data.
• Access all of your data on your device from, and upload to and download from, the Files app on the device. Upload to and download from StraboSpot. Copy and paste between GMDE Lite and Stereonet Mobile.
Skills you need to take full advantage of GMDE Lite
• GMDE Lite can be used "right out of the box" using an online satellite or road base map, and online elevation server, in 2D to measure and collect strikes and dips, plot contacts, do 3-pt problems, etc. This mode requires a wireless or cellular data connection and, in the case of the latter, data download changes will apply. To experience the full power of GMDE Lite, and for complete offline operation (essential in remote field areas), you will need to know how to do the following:
• Produce base maps from whatever source you want in MBTiles format. Because you are producing your own base maps you can use whatever you want (existing geologic maps, USGS Topo Maps, LiDAR hill shade images, etc.) and not just the few option available from online mapping companies.
• Download and format digital elevation models (DEMs) in GridFloat or BIL format. Having a DEM on the device is what allows GMDE Lite to perform its magic, whether calculating an orientation from three points or acting as a pretty accurate rangefinder.
• Know enough about your digital devices to understand how to move files onto or off the device from/to your desktop computer.
What’s New
Version 6.6.4
v. 6.6.4 -- 31 October 2024
NEW -- In the Stereonet Screen, you can now color by type, by tag, or show all with a single highly visible color
IMPROVED -- The New/Modify project screen interface has be updated
IMPROVED -- The export entire project as a .zip file now give you the option of whether or not to include the user collected data. You might just want to export the map(s) and DEM(s) if, for example, you were sending the project to a student's device and you wanted them to collect their own data.
FIXED -- A number of bugs in the POI Details screen that were introduced in a recent version have been fixed.
v. 6.6.3 -- 17 October 2024
NEW -- Overlapping POI labels at a particular zoom level are suppressed resulting in a (somewhat) cleaner look when you have a lot of labels in a small space. You can still tap on a POI that has a suppressed label and get its details, etc.
CHANGED -- Tag types that are hidden will not be hidden regardless of whether you have color by type or by tag selected in Settings. Previously, they would only be hidden if you had Color by Tag selected.
FIXED -- Two finger scrolling of the map while in creating a new Path from Existing Segments now works. It was broken before.
V. 6.6.2 -- 19 September 2024
• Navigate to -- Tap any point on the map and get driving (or walking) directions to that point, from your current location or from a starting point that you tap, in Apple Maps. Once you arrive, you can easily switch back to GMDE Lite to start mapping.
• Rock units have been renamed "Tags" reflecting the fact that you can use them for stuff other than rock units (e.g., you could assign a locality tag to every contact, orientation, and POI in a particular area). The most recently selected Tag is applied automatically to all subsequent observations so, for example, if you are making a number of observations in the Twin Creek Formation or at field station 5, you only have to select the tag for the first observation. Note that tags differ from "types" because types are defined for a particular observation -- "cleavage" can only be applied to orientations, not contacts or POIs -- whereas taps can be applied to any type of observation. Thus, for instance, you can have cleavage measured at different localities and at a single locality you can have a cleavage measurements, and intrusive contact, and several photo POIs.
v. 6.6.1 -- 2 September 2024
• FIXED: a bug in the previous version that would prevent the saving of points of interest (POIs) with attached photos to the database. All users should update to this version.
v. 6.6.0 --29 August 2024
• NEW: You can now assign a rock unit to any POI, Orientation, or Contact. Rock units can be set up in Settings>Edit Types and Rock Units or you can define them on the fly when you tap the Set Types button in the upper right toolbar. Your data on the map can now be plotted using either type color OR the rock unit color. You set this preference in the Settings Screen. Rock units are specific to individual projects. To make sure that your team/students etc. use the same types and units, set up a blank project at the start of your field campaign and then share it with all users.
• NEW: Display planes using the Dip Azimuth and Dip format. This make this choice in the Settings Screen.
• NEW: Redesigned set type (and rock unit) and edit type (and rock unit) screens.
• IMPROVED: Piercing points can now be set by selecting either a planar or a linear orientation (previously they only worked, correctly, if you chose a strike and dip). If you select an linear orientation, then you will need to tap and drag to locate the plane to be pierced.
• FIXED: More bugs....
