QGIS is perhaps the only free GIS platform that's effectively comparable to ArcGIS. Use it for basic GIS tasks like map production and geospatial analysis, as well as more specific tasks like disaster risk reduction, terrain analysis, and environmental resource mapping.
Google Earth Pro is a free software that, albeit not a true GIS, allows visualization, assessment, overlay, and creation of geospatial data. This user-friendly resource is often a useful intermediary for learners who are interested in learning more about GIS and want to start with more basic processes and tools.25 Nov 2021
