On February 23rd QGIS 3 was formally released. Since then the developers have been working on completing installers for Windows, Mac and Linux. As of yesterday the software is ready to be installed on every operating system! To install it you can visit the QGIS Download page.
QGIS VERSIONS QGIS always has two main versions available. There is the long-term release, which is the most stable because it is supported for one calendar year. In addition there is always a latest release. QGIS 3 falls into this latter category, it is the latest release. At the moment the long-term release is version 2.18. The latest release is still considered stable, but a new one comes out every 4 months.
WHICH VERSION TO CHOOSE?
If you want to have one version of QGIS without having to worry about updates, use the long-term release (2.18). If you want to experience all the new features that come with version 3 you will want the latest release (3.0). As mentioned last month, version 3 is a major new release with a lot of changes and new features.
On Windows machines you can have both. You can easily install both versions of QGIS side by side with no conflicts by using the OSGeo4W Network Installer. On Mac and Linux machines you can only have one version, so you need to choose.
QGIS 3 is fast, stable and feature rich. The main issue for many users is that not all Plugins have yet to be ported to QGIS 3. This is because this responsibility falls onto the individual plugin authors. With that said, at last count there were already 117 plugins available for version 3.
Last year Fulcrum rolled out a new service named Community. They describe it as a, “no cost, short term crowdsourced data collection solution for qualified humanitarian projects.”
It works like Fulcrum, but you need to apply for a license. The application form is short and is right on the Community home page. In the application you need to describe your purpose and how long you will be collecting data. You also need to provide a project description. If approved you can invite any number of data collectors via email to share your App (data collection form). It is generally aimed at humanitarian agencies, non-profits, or government agencies. They restrict commercial use of this service.
We used this last fall during King Tide data collection in Miamiand it was a big success. In fact there are four main categories highlighted on the Fulcrum Community page: Hurricane, Tornado, Flood and Fire. If you click on Flood, the King Tide project is the first in the list. Clicking on it brings up a map with the data collected.
One caveat is that the data collected falls into the public domain and can be downloaded freely by anyone. This is possible because the data are anonymized, meaning any private information is scrubbed. The data remain available for viewing and download after the event ends.
It won’t be appropriate unless there is some sort of disaster relief or environmental issue that demands it, but it is another tool to keep in your Community Health Maps toolkit!
