Back to FOSS4G2007...

Introduction

For the FOSS4G2007 conference in Victoria, BC, Canada (September 24-27, 2007) the OSGeo Public Geospatial Data Committee would like to pull together a catalog of local data from the area around Victoria so that there would be a readily available pool of services and local datasets for Exhibitors and Presenters to use during the conference. The hope is that this will bring attention to the efforts being made by the Public Geospatial Data Committee committee. Benefits to the conference would be fast access to services (if we were to host them somewhere locally during the conference), an increased local feel, and a resource so that we could see different applications all working with the same data.

This public data will be available for use by the FOSS4G2007 Integration Showcase.

Data Custodians

Government

Federal

The Canadian Federal Government, often in partnership with Provincial governments, makes various types of data available for free, from various sources.

Provincial

The British Columbia Provincial Government makes some of it's data publicly available for free.

Local

Local governments, such as the City of Victoria, or the Capital Region District may have some data available for free.

Commercial

Various companies and organizations, whether they are Canadian or not, may have data that they would be willing to provide for free.

DataSets

Requested Datasets

If there is a particular Canadian dataset that you would like to see be available at FOSS4G2007, add your request to this section. Please include the following information:

• Dataset information:
  • dataset name
  • link to dataset information (e.g. metadata)
  • link to dataset location (if publicly available)
• Your information:
  • your name (and optionally organization), and a way to contact you
  • your role in the FOSS4G2007 conference (e.g. attendee, workshop/lab instructor, sponsor, etc.)
  • why you are requesting the dataset

Dataset Sources

While the authoritative source for a dataset is the dataset's custodian, for FOSS4G2007 the goal is to have copies of datasets, or partial datasets, on local servers at the conference. To accomplish that, local people will have to do the work of obtaining those copies and loading them onto the local servers.

If you can help with this by providing the conference organizers with a copy of all or part of one or more of the Requested Datasets, add your information to the section below.
