GMDE Lite

September 20, 2024

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....

v. 6.5.1 -- 16 August 2024 • Fix for a bug that could cause a crash while entering text in the details screens. v. 6.5.0 --22 July 2024 • NEW: You can now doing piercing point problems! Select an orientation on the plane of interest and choose piercing pt. Then enter the trend and plunge of the line that pierces the plane and tap and drag on the screen to set the position of the line on the surface. As you drag, the distance from the line to the plane along the trend and plunge and the surface projection of the piercing point is shown interactively. Once you lift the pointer, you'll be given the option to save and plot the line and the piercing point. • NEW: Make a new path out of segments of existing paths/contacts. • NEW: Export the entire project as a compressed, .zip archive. This makes it especially easy to move an entire project -- MBTiles basemaps, DEM(s), and any existing observations -- between devices. • IMPROVED: The handling of segments of topo profiles with no data (e.g., at the edge of a DEM) has been improved. • UPDATED: The users manual has been updated to v. 6.5 of the app, covering the new functionality, as well as a section on using QGIS to create and save MBTiles files. • FIXED: various nagging bugs.

v. 6.0.2 -- 12 March 2024 • A location uncertainty circle is now displayed around the users location when GPS is turned on. If you do not see a circle, that is because your location is more accurate than the size of the location indicator dot on the screen at your chosen zoom level. • Fixed a subtle cosmetic bug in the calculation of appropriate colors.

February 6, 2024

v. 6.0.1 --5 February 2024 • Background GPS track collection -- GMDE Lite can now record GPS tracks in the background when the screen is off or the user switches to another app. The GPS track is limited to a duration of 8 hours in case you forget to stop collecting the track. You must give GMDE Lite permission to access your location always, even in the background in order for background tracking to work. Note that your location is never sent to the programmer and, as long as you use an MBTile base map and have an onboard DEM, your location never leaves your device. If you are displaying a satellite image, your location is sent to Apple to retrieve the appropriate images.

v. 6.0.0 -- 14 December 2023 • Photo thumbnails -- When you tap on a point of interest (POI) which contains a photo, regardless of whether it is a "Photograph" type POI, a thumbnail of the photo will be displayed at the top of the resulting message box. If you tap the photo itself, you will be taken directly to the Photo Screen where you can enlarge or annotate the photo. The remaining buttons in the message box (Show Details, Move, Delete, Cancel) behave exactly as they do in any other POI type. • Auto open DEM with base map selected in the Map Screen -- When you select a base map from the base map selector button on the toolbar in the Map Screen, if there is a DEM with the same root name as the selected base map, the DEM will be opened automatically. This is particularly useful if, for example, you have a regional base map with lower resolution DEM and, embedded in the bigger map, a high resolution base map with, say, a LiDAR DEM of a small area. Selecting the high resolution base map will automatically select the LiDAR DEM, too. You can still select base map and DEM independently in the Modify Project Screen (available from the Settings Screen). • Add, yes, a few additional bugs have been quashed.

November 23, 2023

v. 5.5.7 -- 23 Nov 2023 • Additional error checking for damaged databases and bug fixes. v. 5.5.6 -- 15 Nov 2023 • Rapidly change the base map. If you are like me, you have several different base maps that you use with a single project, maybe a topo map and a a geologic map, etc. The app now scans the project folder and list all available MBTiles files in a box that appears when you tap the map icon in the lower rightmost part of the toolbar. The online satellite map is also listed, and can be chosen, here. Just tap the map that you want to use and it will be loaded automatically. No need to go to the modify project screen any more! • Support for opening and reading ZIP archives created by the desktop version of GMDE which contain all of the elements of a project -- mbtiles base map(s), three files needed for the DEM, and a project SQLITE database. Once you have created such a zip file on the desktop, save it to iCloud Drive or send it directly to your phone via AirDrop or Finder file sharing. Then, in GMDE Lite, select "Open Project" from the Setting Screen, find and tap on the ZIP archive, and the app will create a new project folder in the GMDE Lite Documents Folder and will automatically launch the new project along with any data created on the desktop. This is the easiest way to load a project into GMDE Lite! (The ability to save these zip archives will be available in the next version of GMDE Desktop on all platforms.) • Take a photo right from the map screen. Now, when you tap the add POI button on the Map Screen toolbar, one option will be "Take Photo". If you select that option, the camera will immediately appear. Once you take and select Use Photo, the new POI screen will appear with the photo already embedded and displayed at the bottom of the screen. Photos taken in this way can only be located at the current location. • The data List screen now remembers whether you were displaying POIs, orientations, or contacts and will return to that panel after, say, displaying a stereonet or contact details. • Fixed a bug that would distort photos taken in Portrait orientation. • Fix for a very occasional crashing bug when entering text in a Details screen • Additional bug fixes.
