Map terminology in Maptionnaire:
- System maps are included in every subscription. They are OpenStreetMap-based maps from MapTiler and Mapbox, and include satellite and topographical maps.
- Own basemaps refers to maps that you bring to Maptionnaire. They can be WMTS, WMS, Bing, Mapbox or Maptiler based. To use these in your questionnaire, add them first to Materials. The maps should be in WGS84.
- Map overlays are any additional maps that you want to overlay on top of a more complete map (e.g. a satellite map). E.g. a map overlay could highlight project sites on the map with points. You can bring your own overlays to Maptionnaire as shapefiles (shp), geoJSON, WFS, GeoTIFF or Vector Tile Service. Add them first to Materials. All layers except shapefiles should be in WGS84. You can also create maps with points, lines, areas or grids in Create a map, or add an image to a map (georefencing) in Materials.
Add a map background to a questionnaire:
-
Go to the first page of your survey. Select Map and overlay on top of the page.
- Choose Map as the Page type. If you want to use the same map on all survey
pages, click Make default. -
Select the map(s) that you want to use from Add layer.
-
Choose whether to use metric (km) or imperial (miles) as the map scale measurements.
Finally, set the starting/default view of the map from the window on the right and click Set to save it.
Use the same map on all pages, delete or hide map from view/map menu:
The Actions menu next to each map you select allows you to:
- Select the same map to be used on all pages with map backgrounds
- Remove the map
- Hide by default – only show the map layer if the respondent chooses it from the map layer menu.
- Hide from layer menu – show the layer on the map but hide it from the layer menu so the respondent cannot toggle it off.
Can I use multiple maps in the same survey?
Each survey page can have a different map background and starting location.
Frequently Asked Questions (FAQ):
Yes, you can! For more information on the specific requirements for the shapefile, please see this article.
Most likely yes, you can provided your city's maps are publicly available and you know the URL address of the service. For WMS and WFS, we support maps in WGS84 – EPSG:4326 or 3857. For WMTS, any coordinate system is usually possible, but please contact us at support@maptionnaire.com first.
This could be due to several reasons. Here are some of the most common:
- Check that the server URL is correct.
- Check that the WMS is in or supports the coordinate system WGS84:4326 or 3857.
- Choose a map layer(s) that you want to show. You can do this under Layers in the map editing window in Materials.
- Check that you are zoomed in close enough. Sometimes WMS servers only produce map tiles when you zoom in closer to the location on the map.
- Check with the person(s) responsible for that WMS server that the server allows web-based platforms such as Maptionnaire to use its maps. What they should be looking at are CORS settings and specifically the 'Access-Allow-Control-Origin' setting, which should be set to "*".
Yes, you can use cloud optimized GeoTIFFs on Maptionnaire. Make sure that the file is a reasonable size and in WGS84 – EPSG:4326. Send it to support@maptionnaire.com and tell us which team it should be added to, and we'll process it for you!
Yes it is, with the Pop-up map feature.
Yes it is, if you have included each route as a separate feature within the shapefile. You can then choose the color for each route when you upload the shapefile to Maptionnaire.
Unfortunately we cannot offer Google maps in Maptionnaire due to Google's strict terms of service that stipulates that maps from other sources cannot be combined with their maps. For more information, please see Google Maps' Terms of Service (see in particular #3 License).
First, check that the shapefile contains all the correct files and is in a compressed .ZIP format. If these are correct, then the problem may be caused by a z-dimension in the shapefile. To fix this, simply remove it from the file. On QGIS, you can do this by saving the features again, and in the section called Geometry choosing the feature type (point, line or polygon) instead of Automatic. Finally, uncheck the z-dimension.
Not to worry, for this purpose we have created the Create a map functionality. It allows you to place features on a map and thus create a map layer (in GeoJSON format) that you can add to your surveys.
Yes you can, simply select the Feature labels (the name of the column in the file that contains the names of the different features) in the file's settings when you upload it to Maptionnaire and turn on "Show feature labels".
Unfortunately not at the moment. However, if you have access to Mapbox Studio, you can create a map layer with icons and bring it to Maptionnaire as a WMTS map.
Instead of a more traditional legend, respondents can always open a menu with all map layer options from the upper right corner of the map. You can also add a legend as an image file to the question field.
We use WGS84 (EPSG:4326/3857), but it's possible to use WMTS maps and shapefiles with other coordinate systems. If your map is not in WGS84, contact us at support@maptionnaire.com.
The accuracy of the location depends on both the location and the device. If you are using a laptop/desktop computer (i.e. devices that do not have GPS), geolocation is done through Wi-Fi network data. Essentially, the companies that provide the location search (Google, Apple etc.) record all Wi-Fi networks within for example a city, and where they are located there. When you search for a location, the system (a third-party provider with access to the Google/Apple data) locates your approximate position by looking at what Wi-Fi networks are the nearest to you and where their data tells these networks are located. By finding a matching 'network cluster', the service is then able to tell your approximate (never the absolutely exact) location, with a certain error margin (this is the see-through 'halo' around the location point).
In urban areas where there's a dense concentration of Wi-Fi networks, the location is usually fairly accurate. In rural areas it may not be as accurate due to those areas being more sparsely populated and hence having a lower density of Wi-Fi networks. The error margin in rural locations is therefore usually always bigger.
Finding your location is usually more accurate on mobile phones, as they use GPS. In the case that the location isn't accurate, the address search (magnifying glass symbol) can help. Respondents can use it to find different places if they know the address.
There are a couple of function within the maps that can help stakeholders with this. First, they can click the compass/arrowhead symbol to locate themselves on the map. They can also search for specific addresses using the address search (the magnifying glass symbol).
Locating yourself within the map and locating places through their addresses can be helpful in navigating the map, but of course there will always be individual differences with how people read / understand maps, as they always represent space in a two-dimensional mode that is very different from our every-day spatial experience. If you are worried about respondents having a difficulty finding places on the map, perhaps featuring images of the location in the instructions and/or in pop-ups on the map (e.g. respondent clicks a building and a photo of it opens up) could help? You can also always include follow-up questions in a pop-up after each map marking that the respondent has made, so to ensure that they have marked the correct spot on the map you could always ask them to provide some further details.
