Do you need to install QGIS to use SpatiaLite?
In fact with QGIS, there is no installation required at all as QGIS can create new SpatiaLite databases natively. If you really want to take advantage of the power of spatial databases for storing and managing your GIS data you will probably want to install PostGIS at some point.
How to store raster data in SpatiaLite?
There is a rewrite, librasterlite2, available at https://www.gaia-gis.it/fossil/librasterlite2/index , which is “intended to completely replace the superseded librasterlite”. Thanks for contributing an answer to Geographic Information Systems Stack Exchange!
Is the SpatiaLite database the same as PostGIS?
Fortunately, both SpatiaLite and PostGIS implement the Open Geospatial Consortium’s Simple Features for Spatial specification and so their spatial functions are almost identical and most SQL queries will run on both with very little modification.
Where do I find triggers in SpatiaLite database?
Triggers are SQL functions that are executed in response to database events such as adding or updating data. The Table tab shows the attribute table and the Preview tab shows the geometry of the features. The DB Manager panel also has a SQL window ( )that allows you to write, execute, and view the results of a SQL query on the SpatiaLite database.
How can I interact with the QGIS environment?
For interaction with the QGIS environment, there is the qgis.utils.iface variable, which is an instance of QgsInterface. This interface allows access to the map canvas, menus, toolbars and other parts of the QGIS application. You can create a script, then drag and drop it into the QGIS window and it will be executed automatically.
What kind of database is used in QGIS?
While PostGIS is generally used on a server to provide spatial database capabilities to multiple users at the same time, QGIS also supports the use of a file format called spatialite that is a lightweight, portable way to store an entire spatial database in a single file.
