Beyond Mapping Population Density: Cartography for Big Data

Big data sets are not only 'big' in size and/or number of records, but also in the variety of stories and insights they hold. Piling millions of points on a map can be beautiful and eye-catching, but what story does it tell? Each coordinate in the data provides the opportunity to extract meaningful patterns and observations at multiple scales over a variety of topics. The result? Maps driven by big data that are both beautiful and informative.

Introduction to GTFS: The Standardized Transit Data Feed

In 2005, Trimet (Portland, OR Transit System) and Google set off to create a computer readable format of Portland's multimodal transit system. Since then the GTFS documentation has been released to the public and hundreds of agencies all over the world have adopted this open data standard. While the intent of this data feed was originally to just be used in Google Maps other search engines, developers, planners, and GIS professionals have begun to use this data that many host on the open web.

Developing a Geospatially Explicit U.S. Synthetic Population Using Open Source Tools

Synthetic populations are a means of representing each individual household and person in an entire country. They are created from census data and several other government sources of information in such a way that a computer representation of every household and person can be created with characteristics such as household size, householder age, householder race, household income, age, gender, and location.

Managing Versioned Data with QGIS using GeoGig

This workshop will introduce attendees to GeoGig, a distributed version control system for geospatial data. We will start with a discussion of distributed version control as applied to the specific case of geospatial data, followed by a hands-on session with GeoGig. Then we will explore workflows suitable for data product generation and field collection using the graphical GeoGig interface in QGIS.
