Time & Space in the Natural and Human Worlds:  Historical Ecology and Roman Transportation Routes
and Google Map APIs


Mapping California's Historical Ecology

San Francisco Estuary Institute's historical ecology program synthesizes diverse historical records to learn how habitats were distributed and ecological functions were maintained within the native California landscape. This presentation will show some compelling historical maps from the 1800s and early 1900s that have been important data sources, explain geospatial research methods in historical ecology, and explore some of our findings around the Bay Area and beyond.

Presented by:

Micha Salomon, San Francisco Estuary Institute

Micha Salomon is an Historical Ecology GIS Specialist at the San Francisco Estuary Institute (SFEI).  Micha's been mapping historical and contemporary landscapes at SFEI since 2006.


New Features in Google Maps API


Presented by:

Josh Livni, Google, Developer Relations




Modeling Transportation in the Roman World

This presentation will focus on the creation and representation of ORBIS, a historical transportation model of the Roman Empire. ORBIS was built in PostGIS and uses pgRouting for the pathfinding queries. The model is presented in several ways, including traditional GIS maps, an OpenLayers-based route-finding application, a first-person view of the network, a dynamic distance cartogram and several other data visualizations using the d3.js library.

Presented by:

Elijah Meeks, Digital Humanities Specialist, Stanford University

Elijah provides research support for humanities faculty at Stanford University.

    Such great, relaxed, and welcoming people. I was a cartographer as a work-study student in college working with the first '70 era GPS. It is amazing how far we've come.... Thank you for organizing and making me feel so welcome on my first time and thanks to Google for being Google.

    The topics were fascinating. Ecology to Ancient Rome. Not your typical subjects. Very much enjoyed the discussions.

    Hello Catherine, I now have a project in Zambia which will be the foundation of my knowledgebase and economic development work; I would like to have a network of support for the GIS aspects. I would like to talk about it and field questions for 10-15 minutes. Check out for basic intro; let's talk about it to answer your questions and explore what would be best for the group.
