The Canadian Geospatial Data Extraction tool is a handy resource provided by Natural Resources Canada that most geospatial users in Canada should get to know. It allows users to extract seamless geospatial open data based on specific user-defined geographic area and data options. This puts the control into the hands of the user while downloading authoritative topographic and elevation data to use in their projects.
Users can use the Canadian Geospatial Data Extraction tool to extract topographic from the CanVec series, that contains more than 60 topographic features organized into 8 main themes (transportation features, administrative features, hydrographic features, land features, man made features, elevation features, resources management features, and toponymic features). It originates from the best available data sources covering and offers quality topographic information in vector format that complies with international geomatics standards. Because of its many attributes, CanVec data allows for extensive spatial analysis while also being suited to aid cartographic design.
The basic steps to extracting geospatial data is:
Select the data product to extract
Define your clipping area
Fill out the extraction form and submit it
Receive the email with a download link to your user-defined data set
See further below for the link to the Canadian Geospatial Data Extraction tool with more details on how to use it.
How to access the Canadian Geospatial Data Extraction Tool
Select data to be extracted
This section will list all the current geospatial data types that are available for the dynamic data extraction process. If you hover your mouse over the link you will see a description of the data product.
Select one of the product options such as CanVec for topographic data, or Automatic Extraction Data for building footprints from LiDAR data. The tool will then move you to the next section for more options that you need to fill specify based on your selection.
At any time during the process you can always come back to this section and select a different product (note: reference base maps or overlay data shown in the map navigation window will not be included in the download package).
Define your geographic area
There are a few ways to find your area of interest.
With the Find a location box you can search for an area based on an address, place name, natural geographical feature, postal code, or National Topographic System (NTS) map sheet number.
With the Map Navigation window, you can simply zoom in and pan around to define your area. There are several different base map options available to help orientate yourself.
You can use a shape file to define your area. (note: your shape file must be compressed in a ZIP file format before you upload the file.)
You can use predefined clipping areas such as map sheet extent, or a drainage area.
You can specify a custom clipping area based on an area that you digitize in the map window or specify a bounding box based coordinates that you enter
Looking for Nova Scotia Geospatial Data that you can download?
In this section, you select the options for the data set available based on your needs.
Fill out all required and optional fields for the data type and then click the submit button.
After submitting your request, a message should appear at the top of the Canadian Geospatial Data Extraction tool indicating either that your request was successfully submitted or if an error occurred while transmitting the request to the processing server.
Since the data extraction process is not synchronous you will receive an email once your request is completed, and an email will be sent to you containing a download link to data for your specific user-defined geographic area with any other related information on the product you extracted. There is also a job status section at the bottom of the tool that provides some information about your data request.
The email you receive will look similar to this one:
