Create my first map

The objective of this exercise is to become familiar with the data import process and the map editor within eVouala. To do this, we will use open data from the City of Guelph.

1) Download the dataset required to complete this exercise. You will find:

  • PollingStations-2014.geojson

Note: The data comes from the Guelph Open Data Site.

2) Open the data importer by clicking on the '+' button in the main menu on the top right and import "Guelph Polling Stations" by clicking on the "Data Import" tab. Keep a meaningful name "Guelph Polling Stations".


Note: Click on the "Advanced..." validate the EPSG code and be sure the checkbox "Generate base form" is activated.

3) Repeat the previous step for "Wards", "Streets" and "Property".

Repeat this operation for "Wards", "Streets" and "Property". Notice the properties of the Data Sources in the Library.

4) Once the import is done, return to your Library to make sure you have selected one of the newly imported Data Source, then click the "Create Map" button on the far right.


5) Click on the Legend to open the Layer editor. Notice the options, and be sure to add the 4  data sources newly added to your space on your map by using drag-and-drop. 

6) Reorder your layers to have point layer on the top, then line and polygon at the end. 

7) Select the "Polling Stations" layer. Then, click on the "New Class" button 3 times to cover the different types of buildings used as "Polling Stations".

Tip 1: Change the name of each class in the "Name" field to have a Legend with more clarity.

Tip 2: Use these Filter options for each class:

  •  '[type]'='School' 
  •  '[type]'='Institutional'
  •  '[type]'='Place of Worship' 
  •  Others ...


8) Use only an outline color for properties layer

9) Use only an outline color for the Wards layer, and add a label by using "ward" field

10) Save the map "Guelph Map".

11) Et vouala!
