Setting up a WMS as a background map in Qlik GeoAnalytics

Patric_Nordstrom — Mon, 01 Aug 2022 13:23:21 GMT

Sense Map chart

Example adding a WMS background

1. Add in Content Security Policy (Qlik SaaS)
Origin: nowcoast.noaa.gov Directive : connect-src and img-src
2. Add Map chart
3. Add background layer WMS
url: https://nowcoast.noaa.gov/arcgis/services/nowcoast/radar_meteo_imagery_nexrad_time/MapServer/WMSServer
version:1.3.0
crs: EPSG:3857, transparent, png, layer: Image

Note, use CRS 3857 if the base map has the Mercator projection (default).
Pick CRS 4326 if the base map has the Adaptive projection.

Link to documentation and example.

(QGA Extension map, old kept for reference)

Start by figure out the correct parameters. In this case the source is a WMS with data from the Dutch city Zaanstad.

Note, the urls below has chnaged and not working anymore, principles still applies)

Easiest way to pick up the WMS source and at the same time verify that it works is through a demo page,
for example http://geo.zaanstad.nl/mapproxy/demo/?srs=EPSG%3A28992&format=image%2Fpng&wms_layer=Zaanstad
Select CRS (coordinate system), 4326 for use together with the default adaptive basemap or 3857 with the defualt basemap. Right click on the map image and "Open image in new tab..." . Copy the image url:
http://geo.zaanstad.nl/mapproxy/service?LAYERS=Zaanstad&FORMAT=image%2Fpng&SRS=EPSG%3A28992&EXCEPTIONS=application%2Fvnd.ogc.se_inimage&TRANSPARENT=TRUE&SERVICE=WMS&VERSION=1.1.1&REQUEST=GetMap&STYLES=&BBOX=77018.328125,474244.265625,153485.671875,512224.734375&WIDTH=1208&HEIGHT=600
Remove the following parameters (these are filled in by the map) : BBOX, WIDTH, HEIGHT, VERSION, SRS.
That produces the url to use: http://geo.zaanstad.nl/mapproxy/service?LAYERS=Zaanstad&FORMAT=image%2Fpng&EXCEPTIONS=application%2Fvnd.ogc.se_inimage&TRANSPARENT=TRUE&SERVICE=WMS&REQUEST=GetMap&STYLES=
Fill in CRS and VERSION (in my example EPSG:3857 and 1.1.1 check the WMS url for the version).

Pro tip, "Load via Server" is practical to use if the the WMS doesn't allow CORS.

Pro tip 2, run Sense in the browser (http://localhost:4848/hub/my/work) and use the dev console (F12), good to spot errors from the WMS server.

Pro tip, how to figure out the wms url:

wms - Is it possible to setup fiddler to capture requests from QGIS - Geographic Information Systems Stack Exchange

Is there any instruction to set up exactly right WMS format URL from ArcGis version 10.4 above that can be consumed in Geoanalytics geolayer without any issues ? thanks

Hi Wallace,

In coming releases we hope to make it easier to connect to other sources.

As of now the tutorial above is the best guide.

Thanks,

Patric

Hi Patric

We want to use REST API which requires a token in the Header authentication.

Is this possible to setup in Qlik Geo Analytics. I see only the URL.

Thanks

Alex

Sorry, not today, header tokens are not supported. Thanks, Patric

The approach works very well using the Layer object and the WMS Service URL. How can the GeoAnalytics Map object be set to use another base map? An URL that works as WMS Service URL does not work in the Map Object as "GeoAnalytics Server URL (needs reload)" as the Map Object expects a GeoAnalytics service. What is the recommended approach?

Hi,

The geodata layer is the way to set another basemap.

If the geodata layer is covering then the basemap can be set to "empty".

Use "empty meters" or "empty degrees" to work get QGA to work with arbitrary coordinate systems.

Thanks,

Patric

Hi Patric,

I'm trying to use this WMS as a geodata layer with GeoAnalytics maps: https://geodata.nationaalgeoregister.nl/wijkenbuurten2018/wms?LAYERS=cbs_wijken_2018&STYLES=&FORMAT=image%2Fpng&SERVICE=WMS&REQUEST=GetMap&EXCEPTIONS=application%2Fvnd.ogc.se_inimage&WIDTH=1286&HEIGHT=1286&BBOX=50.568461590702086,2.9387476408566324,53.646827509232324,7.578926173156744&VERSION=1.3.0&CRS=EPSG:4326

After removing the unnecessary parameters for the geodata layer this remains: https://geodata.nationaalgeoregister.nl/wijkenbuurten2018/wms?LAYERS=cbs_wijken_2018&STYLES=&FORMAT=image%2Fpng&SERVICE=WMS&REQUEST=GetMap&EXCEPTIONS=application%2Fvnd.ogc.se_inimage

The result is a empty white box plotted on the map as a geodata layer. There are no errors in the developers console.

I'm using google chrome.

Do you have any idea what is going wrong here?

Regards,

Simon

Hi,

I can see that you are using CRS EPSG:4326 -> set the background map to default adaptive or empty degrees.

Or set the WMS to 3857 if it should allow that.

Thanks,

Patric

Hi Patric, I am new to the GeoAnalytics Server, and now I got a third-party map data for usage instead of the map data pack. How to configure the GeoAnalytics Server such that it is able to use that third-party map directly on the Server call towards QS? Regards, Bevan

Re: Setting up a WMS as a background map in Qlik GeoAnalytics

Patric_Nordstrom — Thu, 01 Aug 2019 09:20:13 GMT

Any third party map server are connected using the geodata or the backgound layer using either TMS or WMS.

To setup a 3rd party TMS as default, check this post:

Hello @Patric_Nordstrom ,

thank you for the explanation , I created this link :

https://geo.zaanstad.nl/mapproxy/service?LAYERS=Begraafplaatsen&FORMAT=image%2Fpng&SRS=EPSG%3A4326&EXCEPTIONS=application%2Fvnd.ogc.se_inimage&TRANSPARENT=TRUE&SERVICE=WMS&VERSION=1.1.1&REQUEST=GetMap&STYLES=

and I put it as server URL for data layer, but I could not see it .

did I something wrong?

Thank you in advance.

Regards

The mapchart has a WMS wizard, that's the easiest way to add a WMS.

The start URL is ok, but it needs to be pruned, pls follow the steps 1-4 above ^^

hello @Patric_Nordstrom , I removed the extra parameters :

https://geo.zaanstad.nl/mapproxy/service?LAYERS=Begraafplaatsen&FORMAT=image%2Fpng&EXCEPTIONS=application%2Fvnd.ogc.se_inimage&TRANSPARENT=TRUE&SERVICE=WMS&REQUEST=GetMap&STYLES=

in properties ( Geodata layer)I changed EPSG to 4326

I put version 1.1.1( which was in linke before)

But still I could not see the map.

I have to notice that I am using qlikview 11.

Do you have any Idea about problem?

Thanks ,

Matsa

Hi @Patric_Nordstrom ,

Finally thanks to your note, we successful to use WMS( not with the link you mentioned )

Now we have another question,about base map when we are using WMS.

Generally we have 3 different types of empty as base map:

1)empty (WGS-84)

2)empty(undefined meters)

3)empty (Mercator)

we thought we have to use 3(empty(mercator)) with CRS--> EPSG:3857 , but it does not work always and we need to change base map to 2.but even with 2 it does not work always.In fact we could not understand the reason of this behaviour( it works sometimes and it does not work other time)

I appreciate your help on this matter.

Regards,

Matisa

All layers needs to have the same CRS (also the CRS of the WMS), the layers are not reprojected in the client.

Empty WGS-84: EPSG:4326 unprojected

Empty (undefined meters) any meter based CRS

Empty(Mercator): EPSG 3587

Default: EPSG 3587

Adaptive: EPSG 3587

Thanks @Patric_Nordstrom for the explanation .

We recognized , we could not see some layers because they are behind of our background( we put one background map with TMS)

We solve our problem in this way:

We deselected ‘Draw order Auto’
We put ‘-10’ as ‘Draw order Adjustment’

Matsa

@Patric_Nordstrom

I am trying to add the following wms link to my geodata layer:

https://nowcoast.noaa.gov/arcgis/services/nowcoast/radar_meteo_imagery_nexrad_time/MapServer/WMSServer

I am not getting the layer on the map. I have set the version to 1.1.1 and CRS to EPSG: 3857 as I am using the default map base.

Do I have something else wrong? The WMS link creates the layer in the regular Qlik map so, so it should be working?

Re: Setting up a WMS as a background map in Qlik GeoAnalytics

Matsa — Mon, 10 Feb 2020 11:15:14 GMT

@Steven_Haught ,

Have you tried with 'Empty(Mercator)' instead of Default Map?

Would you please share the error message which you see on top left of the map?

Regards,

Matsa
