Size issues with GeoJSON

[krabina]

Setup

• Maps version: 7.4
• MW version: 1.31
• PHP version: 7.1
• SMW version (if applicable): 3.0.1

Issue

I have tried the GeoSON capabilities of maps and there seem to be size issues:

As GeoJSON files can become very large, putting them as Wikipage in the Geojson: namespace simply will not work. Is there a way to overcome this?

Secondly the parameter geojson= that points to an small file, works, pointint it to a larger file results either in the page not being saved or the page shows an "Unstrip size limit exceeded (5,000,000)" message.

These ones I have tried

• works: https://data.wien.gv.at/daten/geo?service=WFS&request=GetFeature&version=1.1.0&typeName=ogdwien:UBAHNOGD,ogdwien:UBAHNHALTOGD&srsName=EPSG:4326&outputFormat=json
• unstrip size warning: https://data.wien.gv.at/daten/geo?service=WFS&request=GetFeature&version=1.1.0&typeName=ogdwien:GRDSTKSTADTBEFOGD&srsName=EPSG:4326&outputFormat=json
• shows a blank page: https://data.wien.gv.at/daten/geo?service=WFS&request=GetFeature&version=1.1.0&typeName=ogdwien:FRANZKATOGD&srsName=EPSG:4326&outputFormat=json

Currently the page with the map obtains the geojson from the file or geojson page and saves it into its own content for the map to use. Possible solution: only the url is included in the content and the map pulls in the geojson from this url client side.
