April 2020 Virtual Maptime Show and Tell

For our April socially distanced Maptime, we held a virtual show-and-tell video conference, seeing a variety of interesting projects people are working on, including some from special guests far beyond Boston!

Below is the chat transcript, including links to work that was shown as well as other related items.

February Maptime - QGIS 101

We are going to get into QGIS (formerly known as Quantum GIS). QGIS is free, open-source, and highly capable GIS software. If you’ve ever been curious about QGIS and want to learn more, or never even heard of it, join us! We are going to go through some of the basics of using the QGIS software, including adding data, projecting data, symbolizing and map design, and geoprocessing.

If you’ve been using QGIS for years, come and lend your expertise to help others get started and answer questions.

Before coming, be sure to download QGIS. Beginners are very welcome. Don’t forget to bring a laptop!
