MATIENZO CAVES PROJECT
QGIS v3 with Matienzo Caves Project Data

   The map system (since 2017) for the Matienzo Caves Project is an application based on the widely-used free-ware programme, QGIS. In August 2020 this was updated from version 2 to QGIS v3. Satellite photos, digital terrain model, altitude colours, geology, dowsing data, cave passage centre lines and widths and site positions are shown on a map with surface details and contours. Links to aerial panoramas and videos are available plus historic maps. Two monitors are a definite advantage when bringing up site descriptions, but not essential.

   QGIS allows data to be filtered so that we can see unexplored holes, draughting sites, etc. and also shows underground passage altitudes to compare with the surface. (The fuller QGIS system, used during expeditions and for updating information, additionally allows input of cave grid references through an Excel spreadsheet.)
   QGIS v2 is no longer used. Previous users should update to QGIS v3, download all the resources and uninstall QGIS v2. As an alternative to downloading, the QGIS v3.16 application and all the data is available on a memory stick to Matienzo regulars.
Contact Juan Corrin.
