All-in-one Project QGIS Plugin: Unterschied zwischen den Versionen

Version vom 19. Juni 2016, 14:46 Uhr

This is a software project (and plugin) about sharing and exchanging of a whole "QGIS project" including data and symbology/styling.

• A project by Geometa Lab HSR
• Project Lead: Stefan Keller
• Author/Developer: Tobias Schmitz and Rafael Krucker from Geometa Lab HSR
• Project status: Still in development (nothing published yet on http://plugins.qgis.org/).

Background

Often users want to share their local QGIS data includ

• Proposal to put all data and related styling info into GeoPackage

put everything - including project settings and data of map layers - into one file. When copying/moving project files to other people, it is necessary to manually collect all required files and update the project file. This is even more complicated when working with map layers from databases, web services or temporary (in-memory) data. See also Martin Dobias' GSoC 2012-Proposal. It's related to the proprietary ArcGIS Layer and ArcGIS Map Packages and the standardized GeoPackage.

Currently QGIS project files (.qgs) are XML files that contain mainly project settings including links to resources and symbolization.

Issues:

• Data:
  • A map layer source is stored in files somewhere locally
  • A map layer source is a remote web service which requires credentials
• Styling:
  • SVG files are stored somewhere locally or remote
  • Color Ramps are stored somewhere locally or remote
• Others:
  • A plugin enables or changes a Layer source functionality. There are data resources which require plugins, which are eventually not installed. See e.g. Editable_GeoCSV_QGIS_Plugin GeoCSV.
  • A styling default changed after in a new QGIS version

• Proposal to put all data and related styling info into GeoPackage

Discussion

The user must be able to specify what should be inside the project:

1. link everything (no zipping, just plain XML as before)
2. include everything (put all files into zip),
3. hybrid (put some resources into zip, keep something as a link, e.g. put symbol SVGs into ZIP but keep original links to layers)

Internally the all-in-one projects could work in a fashion similar to ODT from LibreOffice or KMZ from Google Earth: All files required by the projects would be identified and put into a ZIP file (together with the project XML file). All map layers should be converted to a common file-based format (GeoPackage).
