Upload KML on Geo analytics server

sajalgour2309 — Tue, 07 Sep 2021 18:40:28 GMT

Hello guys,

I have few common KML (area) files which we all use across the company. We have qlik Geo analytics server up and running.
Is there any way I can upload these KML on server so that individual developer doesn't require to load the KML again and again in laod script and they can use directly from front end some how?

Regards,
Sajal

No, geodata can't be added to the server that way.

One option is to load the files and then store the geometries as QVD files, which then can added to apps. Faster and easier for the user. Please note, KML is a less optimal geo file format, I recommend using Shapefiles and load with the QGA connector instead. Use the operation Simplify to improve performance.

Another option is to keep the geometries outside of the app, and link in by reference. All QGA layers supports using GeoJSON files as geometry source.

In the attached example with New York City Council district. The data and geomtries are sourced from two sources and linked through the field "district"/"coun_dist":

See Layer Properties>Location Options:

Location Source: Dimension

Location Service URL: ='https://data.cityofnewyork.us/api/geospatial/yusd-j4xi?method=export&format=GeoJSON'

Location Service Type: GeoJSON File

Source Key Attribute: coun_dist

Thanks,

Patric

Thank you Patrick,
Is there any way we can point to any physical stored Geo json file instead of pointing on web server ?

No, it has to be a url, and a location visible to the client or the QGA Server.
