While QGis will allow you to open many GIS files, we are mainly concerned with .tiff (raster) and .shp (vector) files. If you encounter any issues, you can browse and ask questions at the QGis Forum ( no more active ), or another forum.
A spatial join is an operation in a geographic information system (GIS) or spatial database that combines the attribute tables of two spatial layers based on a desired spatial relation between their geometries. [1]
QGIS also makes it simple to share and publish geospatial data as maps, online services, or print maps in a variety of file formats, such as shapefiles, GeoTIFFs, and KML files. Screenshot of Print Composer. In order to prepare printed map with QGIS, Print Layout is used. It can be used for adding multiple map views, labels, legends, etc.
In each of the .shp, .shx, and .dbf files, the shapes in each file correspond to each other in sequence (i.e., the first record in the .shp file corresponds to the first record in the .shx and .dbf files, etc.). The .shp and .shx files have various fields with different endianness, so an implementer of the file formats must be very careful to ...

Derivative works of this file: Creating maps with Qgis.svg This SVG image contains embedded raster graphics . [1] Such images are liable to produce inferior results when scaled to different sizes (as well as possibly being very inefficient in file size).
GeoTIFF is a public domain metadata standard which allows georeferencing information to be embedded within a TIFF file. The potential additional information includes map projection, coordinate systems, ellipsoids, datums, and everything else necessary to establish the exact spatial reference for the file.
A software capable to read coordinate reference systems in WKT 2 format can also read many (but not all) equivalent systems in WKT 1 format. [9] Some caveats exist, notably the removal of the TOWGS84 element [10] which is replaced by the BOUNDCRS element.
