Geospatial Data

Resources

To get help beyond this talk, visit the Berkeley Geospatial Innovation Facility. They have resource guides, office hours, workshops, and more.

Data:

• Berkeley GIF resources for finding data
• Administrative Boundaries
• Climate data
• Open Street Map

Tools:

• Quantum GIS: open source, multiplatform geospatial software

Notes

There are two general types of GIS data. These are:

• Vector data (in shapefiles, for example)
• and Raster data (in pixels, numbered cells).

Where to find Geospatial Data?

For the demo, there are a few places where the data will be downloaded from:

http://gadm.org http://prism.oregonstate.edu http://www.openstreetmap.org

Kevin demonstrated using QGIS (an open source alternative to ARCGIS). http://www.qgis.org/en/site/

He also showed us how to publish our map data on the webservice Cartodb at https://cartodb.com.

Lightning Talks

Aji : TerraView

Aji shared TerraView, a node.js app which can show information about air quality. It has many layers, a straighforward map, using open street map. But, on top of it, using node.js, there’s an open source package called leaflet which allows lots of extra layers to the map. In real time, new values are updated.
