The best example of this is altitude: a topographic map, like the ones you see on the right, can be created from a GIS file in which each pixel represents not only a geographic coordinate, but also information about its altitude. Reversely, objects can be placed on a map and associated with specific coordinates; this is commonly used for ...
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.
A shape-"file" actually consisted of several files, including at the very least a .shp file to store the geometry, and a .dbf file for the attributes, the latter directly adopting the dBase format that was the dominant microcomputer database at the time (despite it being a proprietary trade secret, the .dbf format had been legally reverse ...
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 ...
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.
Well-known text (WKT) is a text markup language for representing vector geometry objects. A binary equivalent, known as well-known binary (WKB), is used to transfer and store the same information in a more compact form convenient for computer processing but that is not human-readable.
A GPX file's main components include waypoints, routes, and tracks: A waypoint (wptType) consists of the WGS 84 (GPS) coordinates of a point and possibly other descriptive information. A route (rteType) is an ordered list of routepoints (or waypoints representing a series of significant turn or stage points) leading to a destination. [ 3 ]
