Matienzo is both the name of a village, as well as a karst area, in northern Spain. The public domain project data for the area was obtained to create this ArcGIS Online app. The app shows cave and karst feature locations, along with cave survey lineplots. View the app.
The legend acts as a filter; click to filter on a feature type. The number indicates how many features of that type are within the current map area.

How the app was made
The data was obtained as KMZ files from the project website, and was manipulated in Google Earth, ArcGIS Pro, and ArcGIS Online. The point locations were further manipulated using filter and calculate functions in ArcGIS Online, as well as some data wrangling using Notepad to remove legacy attribute tags from the original HTML document produced in the project's CMS to produce the results shown in the app. The cave lineplots were published from shapefiles, the locations from a CSV. The app used to display the data is the Interactive Legend configurable app.
