Ecanvasser allows you to visualize the data of your individual Houses, or aggregated List data via our Map page, or in tables and graphs on the Analytics page. Sometimes though, you might want to represent other external data side-by-side within Ecanvasser, and here we've got you covered too!

Why you might use shapefiles

  • Display certain boundaries on your map as a reference

  • Use as a template for cutting your turf

  • Overlay our map with additional data (think previous election results, or maybe target areas for outreach)

In the example below, we've color coded different political units within the city based on what priority they are for your team to engage with:

Technical Specifications

The shapefiles must comply with the following specifications:

  • Either in KML or KMZ format

  • Contain a maximum of 1,000 polygons

  • A maximum file size of 3MB

  • Be styled prior to import

Styling Advice

When styling your file, you'll want to consider what the purpose of the file is.

For example, most of the time, it's likely that the uploaded file is intended to compliment or augment the data already within Ecanvasser, so you'll want to choose a scheme that makes it visible and accessible, but not too overbearing.

We recommend the following is considered when styling your shapefile:

  • High transparency

  • Strong border

  • Pale color palette

File Format

KMZ files are zipped (or compressed) versions of KML files. As such, if you have a KML file that is larger than 3MB, you can reduce it in size greatly by converting it to a KMZ - you can often reduce the total file size by a factor of 3-10, depending on the file. It's a straightforward process, and you learn how to do this here.

Uploading a Shapefile

From the Map page: 

  1. Click your Map View Options

  2. Select to Upload KML

3. Select which, if any KML you wish to display on screen You'll only be able to display one at a time.

Removing a Shapefile

Once uploaded, these files are stored in your Documents page, and can be removed from here too, should you wish.
