What is an ESRI shapefile?
A shapefile is a geospatial file format containing vector data, such as polygons (areas, borders), lines and points.
Are there any requirements for the shapefile?
The coordinate system of the shapefile does not matter, but we recommend keeping shapefiles below 500 kb in size and making sure that the combined size of shapefiles on the same page stays reasonable.
The shapefile(s) should be uploaded to Maptionnaire in a compressed .zip folder that contains the following files: .shp, .shx, .dbf, .prj.
Upload a shapefile to Materials:
-
Go to Materials. Click Map and choose ESRI shapefile from the drop-down menu.
- Upload the compressed shapefile folder.
-
Write the name of the layer in the Public title – it will be shown when the respondent hovers their cursor over the map.
-
If you want to add place names to the map, choose the correct attribute column under Feature labels and turn on Show feature labels. If you have a lot of overlapping labels, consider turning on Declutter labels. It's also possible to change the visual appearance and placement of the labels.
-
Scroll down in the editing window to set the color, size and opacity of the features (style is not automatically transferred to Maptionnaire).
If the zip folder contained multiple shapefiles (e.g. different tram lines), you can select different visualization for each of them, as seen in the image below.
- Click Save to finish.
Add the shapefile to a questionnaire:
-
Go to the questionnaire page > Map and layout.
-
Select Map as the page type. Choose a background map from System maps or Own basemaps.
- Select the shapefile from the menu under Map overlay.
- Set the Default map view and preview the page.
