We will use the QGIS sample data for these Of your own data that you wish to use, but all of the techniques areĪpplicable to any GIS data you have. gpkg extension, which unlike the ShapefileĪre going to start by loading data into QGIS 3.4. Geospatial Consortium and is increasingly being adopted by It isīuilt on a SpatiaLite database, has no file size limitations,Īnd works as one file. GeoPackageģ has chosen GeoPackage as its default format. If you can’t find your format on the list, it is probably not supported in QGIS at this time. To see the latest list of OGR vector formats and GDAL raster formats check out the GDAL documentation. GeoTIFF are probably the most common form of raster data, and QGIS also Shapefiles are the mostĬommon form of vector data today, and QGIS supports this format. Vector data and the GDAL library for raster data. We will then learn how to load and interact with data within QGIS. This article, we will first briefly have a look at the data formats supportedīy QGIS 3.4. To follow along with the examples implemented in this article, you can download the code from the book’s GitHub repository. ![]() By the end of the book, you will have become proficient in geospatial analysis using QGIS and Python.
