Contributing to QGIS Using Git

One of the challenges in any open source project is accepting contributions from people that don’t have, need, or want access to your centralized source code repository. Managing repository accounts for occasional or one-time contributors can be come a bit of an administrative issue. To date, the QGIS project has accepted one-time or occasional contributions through patches submitted via a help ticket. To make it easier for you to contribute to QGIS, we have created a clone of the Subversion repository on GitHub.

GeoApt Spatial Data Browser

This is a project I have had lingering around for a while. It is a geospatial data browser written in Python using the PyQt and QGIS bindings. It allows you to navigate a tree structure and preview raster and vector datasets. Metadata extracted from the data can be viewed as well. It supports drag and drop for any target that accepts filenames (e.g. QGIS). For screenshots and more, see http://geoapt.com/geoapt-data-browser.

New label tools in QGIS

In cartography, it is a frequent operation to set labels to fixed positions, together with the position of the fix point (left/middle/right, Top, Half, Bottom) that is kept constant in case of font change, rotation or zoom. Therefore, three new editing tools to manipulate text labels are now in the QGIS developer version: the move label tool drags text labels to a new position the rotate label tool is for interactive rotation of labels the label property tools opens a dialog that lets the user manipulate the data defined properties of a label (and also the text of the label attribute) All three tools work on the new labeling engine and data defined labeling needs to be enabled for the layer (e.

Testing UMN Mapfiles with QGIS

The Sunday night session of the QGIS hackfest resulted in a new release of the Mapfile Tools plugin. This QGIS plugin allows you to display an UMN Mapserver mapfile in QGIS without running a Mapserver instance. It depends only on Mapscript (apt-get install python-mapscript on Debian/Ubuntu) and allows you to zoom and pan on the mapfile layer. In release 0.6, an output window has been added, which shows error messages and detailed layer information.

QGIS goes 3D

Marco, Matthias and me spent three days at the QGIS hackfest in Wroclaw (pictures). There I got the time to work on the QGIS globe plugin and made a presentation of the current state. As soon as the threading branch (Martin Dobias’ Google of Summer project) is merged into trunk, the globe should make its way into trunk as well. In the meantime you can compile the QGIS branch from guthub to test the globe.

Offline editing plugin for QGIS

For data collection, it is a common situation to work with a laptop or a phone offline in the field. Upon returning to the network, the changes need to be synchronized with the master data source, e.g. a PostGIS database. If several persons are working simultaneously on the same datasets, it is difficult to merge the edits by hand, even if people don’t change the same features. Therefore, Mathias Walker implemented an offline plugin for QGIS.

QGIS 1.5 und QGIS Mapserver 1.0

Kurz nach dem Release von QGIS 1.5, das mit vielen neuen Funktionen aufwartet, ist auch der QGIS Mapserver in der Version 1.0 verfügbar. Der QGIS Mapserver ist ein WMS Server, der ursprünglich am Institut für Kartographie der ETH Zürich entwickelt wurde. In der Version 1.0 können neben der Symbolisierierung mit SLD auch QGIS-Projekte direkt als WMS publiziert werden. Dank der von Sourcepole entwickelten nativen Unterstützung von QGIS-Projekten, können mit QGIS erstellte Karten ohne Konvertierungverluste direkt als WMS-Dienst publiziert werden.
