That is such an absurdly specific but accurate description. I used to manage a site that had a lot of geospatial elements, including various custom maps and obscure (outside of the GIS world) data formats like geotiffs or KML or DTED or the WMM. Coming from a non-GIS background and without the need for an expensive solution like ArcGIS, I have no idea how I would have sanity checked any of it without QGIS
