2. Problem How can we link mm-scale outcrop observations to the big picture? nextback

3. GPS tracking + Photogrammetry Back to Menu Method nextback

4. Blue: shear zones mapped with GPS tracking Back to Menu Import the data 30 m nextback

5. Photomosaics are referenced to GPS tracks GPS accuracy is about 4 m, but relative error is low. Tablet uses the compass for refinement of tracks Back to Menu Import the data 1 m nextback

6. Accuracy is in the error of projection. Back to Menu Precision 40 cm nextback

7. Objects with size of about 1 mm can be mapped relative to satellite image scale! Back to Menu Precision 10 cm Next back

11. Locus Map and Locus GIS Locus Map is available for Android. Pro version for 8.50 € Navigation, Map overlay, GPS accuracy etc… GPS tracking is highly customizable. Locus GIS is in beta-testing phase. Full support for editing/displaying shapefiles. Back to Menu Locusmaps.eu

12. Photographs are taken in an array. Every point should be covered by at least two images. Wide angle lenses are recommended. Field photography Back to Menu

13. Agisoft Photoscan Images are loaded and automatically aligned. From common points, the position and orientation of the photographs are calculated. Back to Menu next

14. Agisoft Photoscan A mesh is calculated to reconstruct the 3D geometry of the outcrop. From this, a texture can be calculated and can be projected on the horizontal plane. Back to Menu

15. Back to Menu Tablet Basically any tablet can be used to display GIS data and for GPS positioning. Common Android models cost about 300 € new. The program “TileMill” can transform large images into a tile database which allows fast display of big maps.
