![]() ![]() Note: Use the 3D View | Tools | 3D Digitize command to digitize coordinates in the 3D view. Click on the View tab in the Properties window. To ensure that your map is horizontal planar, click on the Map object in the Contents window. To use the Digitize command, you must select a horizontal planar map. ![]() Left-click on a map to write digitized points to the Digitized Coordinates dialog. As you move the pointer across the selected map, the X, Y, and Z map coordinates for the current mouse position are shown in the status bar. Pip install pooch if Pooch is not installed on your system yet.The Map Tools | Layer Tools | Digitize command allows you to write map coordinates to a data file. The tutorial data is downloaded using Pooch ( ) and stored in the specified folder. In addition, the file path to the folder where the data is being stored is set. Otherwise, it is recommended to install GemGIS via pip install gemgis and import GemGIS using import gemgis as gg. If you downloaded the latest GemGIS version from the Github repository, append the path so that the package can be imported successfully. ![]() Set File Paths and download Tutorial Data # The X and YĬoordinates of the different geometry objects can then be extracted using extract_xy() of the GemGIS vector module. In the following examples for point, line and polygon data, we have an id column which was created during the digitalizing of the data in QGIS, a formation column containing the name of a geological unit (this becomes important later for the actual modeling) and most importantly the geometry column consisting of the shapely geometry objects. We can inspect the different columns of the GeoDataFrame by looking at its head. The first step is to load the data using GeoPandas. The basic shapely objects, also called Base Geometries, used here are: Each geometry object is stored as shapely object within the GeoSeries geometry of the GeoDataFrames. These files can be loaded with GeoPandas as GeoDataFrames. Vector data is commonly provided as shape files. 08 Sampling Interfaces and Orientations from Rasterġ1 Removing Interface Points within Fault Buffersġ2 Visualizing Geological Cross Sections with PyVistaġ3 Extracting Interface Points and Orientations from Geological Cross Sectionsġ4 Visualizing Topography and Maps with PyVistaġ5 Opening Leapfrog Meshes and GoCAD TSurfaces with GemGISġ6 Extracting Interfaces from Geological Mapsġ7 Plotting Orientations with mplstereonetĢ2 Creating Temperature Maps from GemPy ModelsĢ3 Calculating Thickness Maps with PyVistaĢ4 Plotting Hypocenters of Earthquakes with PyVistaĢ5 Creating Orientations from Isolines on MapsĢ6 Working with Well Data from the Geological Survey NRWĢ7 Opening OBJ and DXF Files with PyVista in GemGISĢ9 Calculating Orientations from Strike Linesģ2 Using ipyvtk with PyVista for Visualizationģ3 Slicing Geological Models with PyVistaģ4 Interpolating Strike Lines with GemGISģ6 Creating Objects for GemGISģ7 Delaunay Triangulation for Isoline Mapsģ8 Interactive plotting with Bokeh in GemGISģ9 Working with Shapely Base Geometries containing Z componentsĤ2 Draping LineStrings over Digital Elevation Model in PyVistaĤ3 Creating LineStrings from PyVista Contour LinesĤ4 Fitting a plane through earthquake hypocentersĤ7 Delaunay Triangulation of Shapely MultipointsĤ8 Georeferencing Rasters using Rasterio in GemGISĤ9 Slicing GemPy Lith Blocks in PyVista with GemGISĥ1 Assigning physical properties to GemPy lith blocksĥ3 Adding anthropogenic geometries to PyVistaĥ5 Extracting Well Tops from PyVista MeshesĦ0 Adding labels to PyVista Contour LinesĦ1 Exporting Geological Maps and Custom sections from GemPyĮxample 16 - Unconformal Faulted Folded LayersĮxample 17 - Three Point Problem and Folded LayersĮxample 29 - Unconformable Dipping Layers ![]()
