6. MapView

MapView is the dedicated map workbench of pyCSAMT: a Dash/Plotly browser application focused entirely on seeing a survey in space — basemap station maps, profile overlays, Surfer-style contours, and interactive 3-D resistivity scenes with fence sections, blocks, depth slices, iso-surfaces, and draped topography. It is the point-and-click layer over the Python mapping API: everything the app draws comes from the same MapView façade you can drive from code, so a scene you build here can be reproduced exactly in a script.

Watch the demo — pyCSAMT v2.6 as an integrated geoscience interpretation platform: EM processing and inversion, 3-D visualization, boreholes, geological information, and the USGS AI Pack in one workflow, illustrated on a real Cu–Mo (copper–molybdenum) mineralization case study. Opens on YouTube in a new tab.

The case study shown is the audio-magnetotelluric survey and 2-D inversion of [Kouabena2025] (bundled as data/AMT/WILLY_DATA/; see Occam2D and the dataset’s own README.md). Prefer a shorter, silent tour instead? See the animated walkthrough on the Overview page.

A good first pass, in order, is Overview → Installation → Loading & Sessions → Views & Controls → Exports → Troubleshooting.
