GeoFieldBook is designed for use in structural geology field mapping projects as a complement or replacement for the traditional paper field notebook and maps. The App integrates the iPad's GPS, camera, data management and mapping capabilities to allow geologists to record structural and formation information, automatically log geo-located data, link images to each record and input pre-defined formation names for different mapping areas. The records are then displayed in real-time on an image base (Apple) with strikes and dips displayed in the correct orientation and color-coded to the formation list. Field measurements and notes can be exported in csv format for integration into analysis software. Existing data sets (records and formation lists) can also be imported into the App. Record types currently supported (more are coming): - Bedding - Contacts - Faults - Joints - Other (generic entries) - Up to five additional user-defined record types with five additional fields per record. Depending upon the record type selected, inputs include: - Name (your entry) - Location (auto recorded) - Time/date (auto recorded) - Dip amount and direction (from your measurements) - Formations (scroll wheel entry) - Notes (your entry) - Five additional user-defined input fields

GST[AR] allows you to browse, download, view, and share geological models in augmented reality. Browse Browse through available models and their features to find a nice selection to present in AR. Models are retrieved from running instances of GST Web. Don’t worry, there are default sources added already, so you can get started right away. Hint: If you see a „Visit“ button near a section of models, you can tap it to learn more about the institution that provides these models for you! When you select a model, you will find a list of features waiting for you. Make your selection and off you go to the AR view. View As soon as the features are downloaded, you will be able to place them on any horizontal surface in AR. Use gestures or sliders to rotate and scale your model. Tap on individual parts to learn about their name or use the legend to even highlight individual features. Superelevation is available via sliders as well! Share When you have placed a feature selection in AR, you get the option to share your session with others! Use the share button to let other peers join your session, synchronize your worlds and you will be looking at the same model in no time. Changes to the model rotation, scale and location will be synced automatically between all peers in the session. Hold down on a model to place your marker to point towards the feature of interest or highlight a certain feature via the legend for all other peers. Settings and customization Customize your experience by changing a couple of settings. In the settings menu, you will have the possibility to change aspects of scaling, how high the models float above the surface or even enable such cool features like "people occlusion" that make your AR scene even more immersive! Furthermore, if you want to access models from a GST Web instance that is not present in the app, you have the possibility to add endpoints of your own.
