This application is designed for the geologist to use during field studies. It lets the user take pictures of the outcrop, interpret the high resolution image and export this information in 3D to construct a 3D geological model. On the image, the user can interpret facies intervals, sedimentary structures and boundaries. The user can add annotations anywhere, measure width/height of sediment bodies (channels, lobes, etc.), and compute bodies statistics. Using an iphone or ipad, the user can measure dip and azimuth and locate this measure on the picture or use its GPS location to export dip markers to the 3D model. Once the user defines the image scale, all interpreted boundaries and intervals can be exported in 3D in GOCAD format (image, interpretations boundaries, dip/azimuth and facies intervals). ## Key features - High-resolution outcrop imaging - Interpretation of facies, structures, and boundaries - Annotation and measurement tools - Dip and azimuth measurement - GPS location integration - 3D geological model export (GOCAD format) ## Recent user reviews (1 of 1) All indexed reviews: https://appshunter.io/ios/app/outcrop/id1056810833/reviews.md ### 1/5 — Outcrop Review *2022-09-01* Horrible app, little to no instructions, just a drawing tool for photos that is full of bugs. ## Frequently asked questions about Outcrop ### What geological features can be interpreted with Outcrop? Outcrop allows users to interpret facies intervals, sedimentary structures, and boundaries directly on high-resolution outcrop images. You can also add annotations and measure the dimensions of geological features like channels and lobes. ### How does Outcrop help with 3D geological modeling? Once you define the image scale, Outcrop exports interpreted boundaries, facies intervals, and dip/azimuth measurements in GOCAD format. This data can be used to construct a 3D geological model. ### What devices is Outcrop compatible with? Outcrop is available for iPhone, iPad, and iPod touch devices. It leverages the camera and GPS capabilities of these devices for field data collection. ### What is the update frequency of Outcrop? The latest version of Outcrop is 1.1.5, which was last updated on February 12, 2018. This indicates a less frequent update cycle for the application. ### Does Outcrop have ads? No, Outcrop does not contain advertisements. The application is free to download and use without any ad interruptions. ### What is the user sentiment for Outcrop? Based on the provided data, Outcrop has a rating of 1.7 stars from 3 ratings. This suggests a generally negative user sentiment, with users likely experiencing significant issues or finding the app not meeting their expectations. ### Can Outcrop be used offline for field studies? The description does not explicitly state offline capabilities. However, features like image capture and interpretation are typically designed to function in the field where internet access may be limited. ### What export formats does Outcrop support for 3D models? Outcrop specifically supports the GOCAD format for exporting 3D geological models. This includes image data, interpretation boundaries, dip/azimuth measurements, and facies intervals. ## Version history (last 5 releases) ### 1.1.5 — 2018-02-12 This app has been updated by Apple to display the Apple Watch app icon. This release provides bug fixes and some enhancements. The main enhancement makes use of the IOS 11 new Files App to facilitate exports of GOCAD model files. Files can now be exported directly to the Files App. This new option can be found in the Save interpretation popup. Additional enhancements have been made to the Image selector, to the labeling of boundaries in the Interpretation View, to the interpretation toolbar and to the process of measuring dimension of bodies. The main bug fix was about the display of facies pixmap. ### 1.1.4 — 2017-11-10 Ported to IOS 10.3 Corrected utilisation of full resolution photo capture. Corrected cleaning-up of images and interpretations. ### 1.1.2 — 2016-06-10 Added option to delete a project. Increment name of new image. ### 1.1.1 — 2016-05-06 Simplification of UI to enter the reference scale. Corrections of the display of the callout view on the Map display. ### 1.1 — 2016-04-14 Added Issues/Suggestions button. Allow horizons to be split by faults (an horizon can be now in multiple parts). Corrected stability issues while digitizing and working with color-fill. Corrected line editing toolbar when shown after switching to another tool. ## Apps similar to Outcrop | App | Rating | Price | Category | | --- | --- | --- | --- | | [CADraw](https://appshunter.io/ios/app/cadraw/id1526269907) | 2.7 (9) | Free | Productivity | | [Geology Clinometer: GeoCompass](https://appshunter.io/ios/app/geology-clinometer-geocompass/id6450886950) | 5.0 (1) | Free | Productivity | | [HSvu](https://appshunter.io/ios/app/hsvu/id1022333171) | 3.0 (2) | Free | Productivity | | [ZWCAD Mobile - Mobile CAD](https://appshunter.io/ios/app/zwcad-mobile-mobile-cad/id545035436) | 4.3 (302) | Free | Productivity | | [Sketch Viewer UP-model browser](https://appshunter.io/ios/app/sketch-viewer-up-model-browser/id6447847214) | 1.6 (10) | Free | Productivity | | [MoCoNC](https://appshunter.io/ios/app/moconc/id1574512474) | — | Free | Productivity | --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
