Years ago (2011), Nathan Woodrow did a visualization of code commits between QGIS 1.6 and 1.7 using Gource. I wanted to contrast the slow beginning of QGIS in 2002 with the flurry of activity in recent years.
Gource can analyze a git repository and display the activity. The video below begins with the very slow start of QGIS development in 2002. Since displaying all of QGIS activity using Gource would result in a long video no one would want to watch, I took a look at the time period from 2002 to mid-2004, then jumped to June of 2021.
Today we’ll use the qgis2web plugin to export from QGIS to Leaflet. The QGIS project, a location map for the third (in progress) Life on the Alaska Frontier novel, looks like this:
Installing qgis2web The qgis2web plugin is installed like any other. Click on the Plugins->Manage and Install Plugins... menu item, click Not installed, and then find qgis2web in the list. Click the Install plugin button to complete the install.
There’s been several posts to GIS StackExchange along the lines of:
Where’s my .qgis3 folder?
Prior to QGIS 3, the .qgis/.qgis2 folder was found under your home directory. At version 3, the folder has moved to a more standard profile location for your operating system.
There are a couple of ways to determine where the folder is located:
Use the Settings->User Profiles->Open active profile folder menu item Use QgsApplication.qgisSettingsDirPath from Python or the console Here are the “standard” locations for Linux, Mac, and Windows, as found under your HOME directory:
If you’re a developer, or have looked at the QGIS source code, you’ve likely noticed that most C++ classes in the project start with Qgs.
Back before the dark ages of QGIS, Trolltech (now Digia) allowed you to reserve name prefixes for classes that used the Qt framework.
Shortly afterwards, I reserved the gs prefix for my use, resulting in class names that start with Qgs.
You might think this is based on some mangling of words like QGIS or perhaps GIS, but it was purely egocentric:
Nominations for the QGIS PSC closed at 00:00 UTC on August 25, 2013 [1].
With only one nominee for each role, the PSC unanimously moved to accept each without election.
The QGIS PSC welcomes new members Anita Graser, Richard Duivenvoorde, and Jürgen Fischer.
The PSC is now composed of:
Chair - Gary Sherman Community Advisor - Otto Dassau Design Advisor - Anita Graser Financial and Marketing Advisor - Paolo Cavallini Infrastructure Manager - Richard Duivenvoorde Release Manager - Jürgen Fischer Technical Advisor - Marco Hugentobler Testing/QA Manager - Tim Sutton The new PSC members begin their terms immediately.
The QGIS Project Steering Committee (PSC) has announced a call for nominations to fill three vacant positions:
Design Advisor Infrastructure Manager Release Manager Nominations are open until August 24, 2013. For details on the PSC, vacancies, and how to nominate someone, see the [Call for Nominations August 2013] (http://hub.qgis.org/projects/quantum-gis/wiki/Call_for_Nominations_August_2013).
Do you remember this?
If so, you’ve been using QGIS a long time…
OGR and PostGIS support No raster support Three widgets on the Symbology tab No symbology in the legend But you could use it handily on a 640x480 display.
Well not quite destruction, but a bit of hair pulling…
While working on an update to the Plugin Builder, I encountered a small problem. The Plugin Builder displays the version number in the title bar of its main window. After bumping the version number to 1.8.4 in all the requisite places, it still showed 1.8.3 when testing.
Using grep on all the source files revealed no instance of 1.8.3 in any file.
The Quantum GIS (QGIS) project is happy to announce that the Asia Air Survey Co., Ltd (AAS), a Japanese international consulting company, has become a Gold Sponsor. AAS has committed to providing 9,000 EUR (~$11,000 US) each of three years, beginning in November 2012.
The AAS sponsorship is yet another indication that QGIS is a mature and stable project which continues to provide innovative open source GIS software.
The QGIS Project Steering Committee (PSC) wishes to thank AAS for their continuing commitment.
It was ten years ago, on July 19, 2002, that QGIS was officially unveiled. That first release was primitive, supporting only PostGIS layers and having little in the way of navigation controls. Invoking the open source mantra of “release early and release often,” I announced it on Freshmeat and waited.
Slowly it began to attract attention—not all of it positive. Some questioned why I was starting a new open source GIS project when there were others I could join.
The QGIS project has a number of support channels. Like many open source projects, these are loosely coupled. Recently the forum was made read-only and this has prompted a number of questions and concerns about how to receive support. This post outlines the ways in which you can get your questions answered.
Home Page The QGIS home page has links to all the documentation and community resources. The navigation panel on the left has links to both the Community resources and the manual.
The forum (http://forum.qgis.org) has been closed for new registrations and marked read-only. Users have been encouraged to use http://gis.stackexchange.com instead.
If you have an thoughts on the closure, good, bad, or otherwise, please comment.
The raster calculator allows you to perform mathematical operations on each cell in a raster. This can be useful for converting and manipulating your rasters. Operators include:
Mathematical (+, -, *, /)
Trigonometric (sin, cos, tan, asin, acos, atan)
Comparison (<, >, =, <=, >=)
Logical (AND, OR)
To perform operations on a raster or rasters, they must be loaded in QGIS.
One of the difficult things to track in the open source world is the number of people who actually use your software. In the proprietary commercial world you have licenses, invoices, and so forth. In the case of QGIS, we can track the total number of downloads from qgis.org, but this doesn’t represent the total installed base. It is impossible to accurately determine the actual number of people using QGIS, but we can get an approximation of the number and where they are in the world.
I added a simple feature that allows you to search the IRC logs from #qgis back to May 10, 2006.
The search is case sensitive and will return a list of all matches. Not too smart but it will get you close to what you want.
