QGIS How: Package Layers Into Geopackage In QGIS

Описание к видео QGIS How: Package Layers Into Geopackage In QGIS

A GeoPackage is an open, standards-based, platform-independent, portable, self-describing, compact format for transferring geospatial information. This video shows how to package layers into Geopackage in QGIS

ADVANTAGES OF GEOPACKAGE
I. Open source, based on SQLite database
II. Very lightweight but highly compatible across environments (esp. in mobile devices where connectivity & bandwidth is limited)
III. Geopackages are generally ~1.1–1.3x lighter in file size compared to shapefiles and almost 2x lighter with respect to geojsons.
IV. Loading Geopackage file on QGIS or making queries on the file database is fast.
V. There is no limit on the file size and it can handle a large number of features in a smaller file size.
VI. Compared to shapefiles, the column headers can be full names and right by providing the correct context for each column.
VII. A single geopackage file can have multiple vector layers with each layer having a different geometry type.
VIII. You can have non-spatial attribute tables (pandas tables) as well along with vector layers.
IX. The file can be handled using GDAL, QGIS, Python, R, SQLite and Postgres
X. Etc.
