A little while back, I posted a few mapping extensions that read in various kinds of data to allow mapping of regions and data on Google Maps. One major problem with those is that Google is now charging money for useof their mapping product, so in order to use this extension on any grand scale,they'd need to purchase licensing.
So, in response to this, I've built an extension which uses all open source (free) products to provide some similar mapping capabilities(and then some). The tool which provides the scrolling and "slippy" map features is called OpenLayers which reads in map imagery from OpenStreetMap. What I've done this time, however, is built the extension to read in KML files for the regions. KML is a format that is very common in the industry (Google Earth uses and creates the files) ,and there are many tools out there to convert other formats (like shape files) into the KML format.
So, for example, I went and found a KML file for the US 50 states and put it into this new extension, and was able to create a map similar to my other US Map extension:
New Features
Above and beyond the normal features of the extensions I created for Google, this extension provides a few new features:
I've attached the extension as well as a QVW and quick guide. In the extension is a sample KML file called us_states.kml that can be used with the example QVW.
Please let me know if you have any questions. Hopefully this is useful to people.
Due to some issues with versions of Internet Explorer prior to 9 and how it handles different data formats, it is now necessary to change the KML file into an XML file prior to loading it into the extension. So, for example, if you have a KML named "counties.kml" you need to change the file extension so it becomes "counties.xml". Hopefully I'll eventually get time so this last step can be avoided, but for now it's necessary in order for the extension to work in IE8.
I've updated the attatchments on this post to use an XML file, so the examples should now work.
Hello Team
can any one upload the proper qar or zip for the openlayer map,I was extracted the once which was attached at this community and can able to see lot of QVPP files got missed and i could not able to see the map. kindly find the attachment.
Thanks all for this discussion. I have sales data that is available at the country level and for US i have it at the state level. I want to be able to show this at the country level and when i select US i want to be able to see it at the state level. Is this possible using this extension? also how would i go about creating the kml file? I assume i would need a different kml file.
Thanks in advance for your help.

Hi Vishal,
There's a few options available to you in achieving this. Probably the simplest way is via this extension, you can use an expression to determine the scope of your selection and change the KML file from a country level one to a state level one as desired. Your expression might be something like:
if(getfieldselections(Country_Name) = 'US', 'state_level_kml_file.kml', 'country_kml_file.kml')

Hello,
first of all, this extension is really great, thanks a lot for that.
But I have a problem with wrong popups showing for areas which are inside other areas.
For example, I have Innsbruck (City) and Innsbruck-Land, the polygons and colors are fine, but the popup for Innsbruck shows the vales from Innsbruck-Land.
Same for other big Cities in Austria, where the polygons overlay.
Is there any way to show the right popups?
Thanks in advance!

Dear Brian,
I have tried many things but I end up in the same position as many guys here with a blank screen of the actual map object.
I have installed the quickMap extension, and also your extension that I have tried to tweek with.
I am using::
Qlikview v.11, 11.20.12852.0 SR11 64bit
Internet Explorer:11.0.9600.17801
OS: Windows 7 Pro, SR1
Any ideas what could be the problem of not seeing the object?
Did you get it to work Francesco?
I have the same problem.
Using:
Qlikview 11.2, SR11
Internet Explorer 11
Windows 7 Pro
Hi Daniel,
did you try the latest version of Brian's Extension?

Hi...
I've downloaded the latest version of the extension but I also don't see the maps.
Has anyone succeeded to see it?
Do I have to do something additional in order to see the sample map?
Linoy,
Alexander is right, try the latest Extension made by the same developer, Brian Munz:
Ok, the answer is simple, its an outdated Extension that is not working anymore with the latest Qlikview version.
You have to download the latest QuickMap extension from GitHub, made by the very same developer, Brian Munz:

Good luck everyone!
