![]() ![]() If so, you can skip installing GDAL separately and jump directly to the QGIS installation. If you intend to install both GDAL and QGIS on a mac, first check out if the QGIS installer maintained by William Kyngesburye ( KyngChaos page) also contains the complete GDAL package. You just have to check out and read the instructions both on the official QGIS site and at KyngChaos to make sure how to do at this point in time (when you read this). But then QGIS set up their own installer for some versions, and then returned to letting William Kyngesburye do it. Historically, William Kyngesburye ( KyngChaos page) has maintained installers and instructions. To get the components setup and working together, might, however, be a bit more complex. Working with GDAL, QGIS and GRASS on MacOS is not more complex compared to other operating systems. That is, however, not covered in this blog it is covered in the QGIS manual Module: GRASS. QGIS actually contains GRASS and SAGA GIS, and if you prefer a graphical user interface (GUI) you can use GRASS under QGIS. ![]() For specific tasks I use Geographic Resources Analysis Support System (GRASS) and for viewing maps, setting colors and creating map layouts I use Quantum GIS (QGIS). Most of my GeoImagine processing I do using Python and the Geospatial Data Abstraction Library (GDAL). The Open Source Geospatial Foundation OSGeo site contains a lot of OS alternatives. There are several commercial packages available, but I only use Open Source (OS) GIS. Working with geospatial data requires a Geographic Information System (GIS).
