Map Club, Session 03 — Introduction to QGIS (PLUS: Buttons!)

20160712_Banner_v1

By popular demand, Map Club dove into a structured exploration of QGIS this week. QGIS is a free and open source geographic information system that offers powerful tools for data editing, viewing, and analysis. In contrast to previous sessions, this session focused on a few key areas: importing and exporting different file types, re-projecting raw data, and geocoding a list of locations using the MMQGIS plugin.

Attendees worked on completing an introductory projection tutorial, as well as using MMQGIS to extrapolate lat/lon coordinates from a list of place names.

Map Club, Session 02 — SVG Maps with Kartograph

20160712_Banner_v1

This week, Map Club embarked upon its second session by experimenting with Kartograph, a lightweight framework for building interactive map applications without an external mapping service. Kartograph is comprised of two libraries: the first is a Python library, Kartograph.py, which generates compact, Illustrator-friendly SVG maps from shapefiles and PostGIS; the second, Kartograph.js, is a JavaScript library for creating interactive SVG maps based on Kartography.py SVG maps.

After installing the framework and its dependencies, attendees experimented with Kartograph.py to transform shapefiles into web-ready SVG maps. Jingying accessed NYC OpenData to generate a static map of galleries in New York City:

Next week, we’ll take a more workshop-like approach to learning QGIS, a free and open source geographic information system. See you then!

Map Club, Session 01 — Exploring CARTO & CARTO.js

Map Club kicked off its first summer session with a dive into CARTO.js, a unified JavaScript library that interacts with the CARTO (formerly CartoDB) web mapping and visualization engine.

After setting up CARTO accounts and local testing servers, attendees prepared datasets for upload to the CARTO interface, explored different geovisualization methods provided by the platform, and experimented with interactive capabilities offered by the CARTO.js library.
