WMTS (Web Map Tile Service) is a geographic information system database that contains different map layers. To use these types of maps, you need to connect to the server and choose the map layer or layers that you want to use. You can use WMTS layers as base maps or as overlays in your questionnaire. If the WMTS map that you want to use is not in the WGS84 EPSG: 4326 or 3857, please contact us at email@example.com. However, you should be able to use a WMTS map in virtually any coordinate system in Maptionnaire.
WMTS layers are easy and reliable to use and we recommend using WMTS or WMS layers in case you have large quantities of data you want to use in your questionnaire.
For further information, you can read more at OGC.
Please note that you should not try to enter the URL of the map layer into Maptionnaire, but the general URL connecting to the WMTS server. Layer choices are made once Maptionnaire has established a connection with the server.
How to upload a WMTS layer?
Go to Materials, choose the Maps tab and click Add Map on the upper right corner. Choose Add WMTS layer from the drop-down menu. You can also add the layer directly in the questionnaire editor in the Maps section of the main settings.
Enter the WMTS server URL in the window that opens. If the WMTS that you are using requires an API key, you can enter it in the section URL Parameters. In the first field, enter the name of the parameter as it would be written on the URL, e.g. api-key. In the second field, write the ID in the parameter, e.g. the individual API key you have been given for using that map.
Once Maptionnaire has established a connection to the server, you should choose the layer or layers that you want to use in your survey by typing their names in the Layers section. Remember to also check that the coordinate system is WGS84_Pseudo-Mercator in Matrix set.
- Finally, click Create item, or Save if you are editing the settings after creating the item.
