Development started in 2002 by Gary Sherman
## Where do we left off? 2nd PDW in Flagstaff, 2015 QGIS was at: * stable realease: 2.8.2, upcoming: 2.10 * platforms: GNU/Linux - OS X - MS Windows
## Where are we today? 4nd PDW in Flagstaff, June 19th 2019 QGIS is at: * Stable: QGIS 3.6.3 'Noosa' (17.05.2019) * LTR: QGIS 3.4.8 'Madeira' * GNU/Linux - OS X - MS Windows - Android (QField) * Upcoming v3.8 (now feature freezing) * GRASS modules accessible from the QGIS GUI

Built-in OGC services

OGC services accessible from QGIS:
  • Catalogue Service for the Web (CSW)
  • Web Coverage Service (WCS)
  • Web Feature Service (WFS)
  • Web Feature Service - Transactional (WFS-T)
  • Web Map Service (WMS)

QGIS is a project within OSGEO



The Open Geospatial Foundation (OSGeo) is a non-profit non-governmental organization whose mission is to support and promote the collaborative development of open geospatial technologies and data.

QGIS for planetary data handling

and

Planetary geoscientific mapping

USGS Astrogeology's First Published Map in 1961

QGIS for planetary mapping: elements


  1. Digitizing plugins
  2. Symbology
  3. Crater count tool

Digitizing interface

Interpretative mapping requires a lot of user-input. Stream digitizing support is critical with modern input devices

Digitizing with beePen plugin

BeePen plug-in by Mauro Alberti

latest version implements smoothing + simplify chain

Digitizing with bezier plugin

Bezier Editing by Takayuki Mizutani

works directly on exisitng vector layers

Geologic symbols lib and design for QGIS

Users can download the existing library and contribute with currently missing symbols

Circle Craters Plugin

Provides a 3-point crater digitizing tool in QGIS, exporting the data into a Craterstat (Michael et al, 2013) compatible file

  1. Developed for QGIS 2.6 by Sarah Braden
  2. ported to Python3 / QGis 3.6

Entry point for updates/discussion

A thread on QGIS for planetary mapping has been opened on the openplanetary.org forum

Acknoledgements

A special thanks goes to the all the QGIS/FOSS4G developers, contributors and sponsors, and planetary data users testing these tools!

that's it!

... and that's only the beginning!
