SFU-licensed data (SFU login or librarian-mediated access)

Abacus 
The licensed geospatial data that SFU Library has purchased are available for instant download in SFU's section of Abacus. Browse datasets or use the search box in the top right to search by keyword(s). All of the DMTI Spatial datasets are in Abacus. This is a popular collection of detailed geospatial data for Canada that includes current and historic datasets of road networks, parks, water bodies and rivers, rail infrastructure, business locations and building footprints, digital elevation models, neighbourhood and community boundaries, postal codes, and more. The most recent DMTI data is the CanMap Content Suite v2021.3. Read the data dictionary to find what data files are included. Note: you will need to log into Abacus before you can download the datasets. 

Note: the DMTI Spatial datasets are licensed for specific uses only. Make sure to carefully read the Terms of Use section in the Cataloging Information tab for each dataset in Abacus. In particular, the DMTI Spatial datasets are to be used exclusively for teaching, academic research and publishing, and/or planning of educational services within SFU. This means the data can only be accessed by educators, students, and other staff members at SFU, and cannot be used for any contract-based or income generating work (whether privately or through SFU). Also, no vector data can be published - any journal article or research communication can only include raster images. In this context, 'published' could also mean uploading map products to online web GIS platforms such as ArcGIS Online or StoryMaps.

Abacus also contains statistical and numeric data.

Integrated Cadastral Information Society (ICIS) Data
Read about ICIS data here. The GIS & Map Librarian (Sarah (Tong) Zhang; tza68@sfu.ca) can download the following datasets on behalf of SFU researchers. These datasets can be downloaded by regional district or for the entire province.  Download the list for available dataset (on Abacus, under the Files tab, ICIS_File_Manifest.pdf) to see what files are available. Note you will need to log in to Abacus to download the file. 

  • Cadastral data for all of BC
  • AddressBC Data - A central authoritative, accurate and accessible point-based civic address registry for British Columbia.
  • BC Assessment Data - Geospatial representation of the assessment roll. It contains a record for almost every assessed property in British Columbia.  Unlike a legal cadastre fabric, it is an ownership fabric. This means there may be many legal lots represented by one assessed property or folio.

BC Assessment Data
SFU Library is participating in a pilot to enable SFU researchers to access BC Assessment (BCA) Data including value assessments and sales information for properties in British Columbia. SFU Faculty may request access to the data and can use the data in course assignments under the terms of the agreement. For more details on what data is included and how to access the data, refer to this page

BC geographic data - Many products on this page are free and can be downloaded by anyone, Raster topographic maps, for example. However, some have a cost. The GIS & Map Librarian (Sarah (Tong) Zhang; tza68@sfu.ca) can download the following products on behalf of SFU researchers for free or a reduced cost. These products are made accessible to the SFU community via a license agreement negotiated by the Library and are for academic use only. 

LandScan Global Population
Country-level demographic data, 1st level admin demographic data, pixel (1km²) level data, and a layer with area calculations for population density. Country and 1st level admin level data include age, gender, and age-by-gender population breakdowns.

Open data portals across Canada
Not an exhaustive list. If you don't see the area that you're looking for, try searching for the name of your municipality, region, or province + "open data" in Google. Note that sometimes you won't find data at the most granular level and will have to take a step back—for example, you can often use regional, provincial, or even national data to get a municipality.
