Extension to create Map Offline

Mon, 26 Jan 2026 16:26:21 GMT

Hi everyone,

I'm looking for an extension to create maps. Please, notice that my QV server doesn't have access to the internet.

I have had a look at GoogleMap Cluster but it seems like I do need an internet access cause I've tried it on my personnal computer with personnal edition, the webview is fine when I am logged to the internet but doesn't work anymore when I am offline.

I also had a look at QlikMap QlikView Qlik Map, but well, the demo on the website (Launch demo) doesn't work.. (perhaps it comes from my computer ?)

Any ideas ?

Thanks for your help

The extensions are not really the issue here. You need to get an offline copy of the mapping tiles that the extensions are displaying. OpenStreetMaps allows you to download their mapping data for free. Assuming you have enough storage space on your hard drive you could them point the extensions to the mapping tiles you downloaded vs a URL.

Hi Laura,

to work offline (no internet but local network) with mapping data a good solution would be to run a OpenStreetMap tile server in the local network. Then you can point your extension to it. But you also need to have the resource files of the extension locally which is not the case for the most OSM extensions I have seen here (quickMap etc.). Let me know if you need professional support..

Laura,

Here is a tool to download the tiles http: / / wiki.openstreetmap.org/wiki/JTileDownloader

And the Qlikview Quick Map extension project files with a demo QVW you can get here:

..but quickMap still needs internet access to load resource files like OpenLayers.js etc. (see script.js). Can be adjusted of course. I made my own extension using local OpenLayers.js

Thank you all for your answers

So, I need to download the OpenStreetMap tiles but they take quite a lot of space ? What if I only want the map for one country (France), can I download only this one ? And then I have to point the extension to those files.

Ralph told it won't work with all extensions. Do you know a good extension to do that ? And then, how do I make the extension point on the map files ?

Thanks again

Hi Ralf,

Do you think there is a simple way to create offline maps ? I mean, I am not sure I can make my own extension as you did Moreover, I don't have much free space on my QV server.

Hi Laura:

In a server without exit to internet you need the Brian Munz's SVGMap Reader

http://branch.qlik.com/projects/showthread.php?136-SVG-Map-Extension

This is the last version and it works so fine

Hope it helps

Joaquín

Hi again Laura:

Here you have a doc with the instructions, I downloaded from this community but I don't remember where.

Unfortunately, there is no simple way.. But what do you really need for mapping? Sometimes it's just enough to show some regions with SVG/KML files. But if you really need to go down to street level it's getting quite complex and you will need some GBs of space for the tiles.

Thanks Joaquin, but there is no internet access on my QV server and :

"An SVG image is basically an XML document which contains data telling the internet browser how to draw an image. "

You need to get the lat/lon bounding box of your country (France:GeoPlanet Explorer) then set the coordinates in JTileDownloader and start downloading each zoom level (in this case it's prepared for Germany bounding box):

This works locally...

Ooops,indeed ! Sorry

How does it work with SVG ? Your example works fine but I cannot see how it works. Are the maps integrate in the extension or do I have to find myself the maps I need ?

I must have some fields in my dataset to "join" the map like region ? How precise can I be with an SVG ? Can I join on city ?

Can I use longitute and latitude to draw a point ? Or can we only draw region ?

I cannot find any documentation about svg..

Thank you again Ralf

Hey Laura,

The Google Maps Cluster extension does not require a internet connection on the server.

As long as the clients are connected to the internet it should work.

Hi Alexander,

Good point of discussion.

It´s true to say in general, an extension using some web API like maps doesn´t require an internet connection in the qlikview server, just only in the clients ?

Yes, 9/10 times the server does not require a internet connection.

Extensions are built using javascript which is executed in the clients browsers so any references to external content would be fetched by the browser and not the server itself.

For example, if you use Qva.LoadScript() to load a library from the web the extension would simply instruct the browser to go fetch that library and the qlikview server can stay isolated from the web.

And the other 1/10 case ?

Re: Extension to create Map Offline

Alexander_Thor — Wed, 10 Dec 2014 18:17:54 GMT

Ha, I tried but could not come up with a good use case for the 1/10 but playing it safe

I guess if you have a extension which talks with a custom component on the server that in turn talks with a web resource your server would need internet access.
