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.
Hi Arun ,
Could you please share the XML file of INDIA so that i can try the same in my dashboard.
It would be very helpful.
Thanks & regards,

Hi Brian,
is possible to develop the application to allow multiple selections (with ctrl) in the map?

The short answer to this is yes, it is possible. In terms of when I might be able to tackle it, I'm not sure, but when I (or anyone else who wants to take a shot at it) add this functionality, I'll check it into the github location here: https://github.com/brianwmunz/QuickMap-QV11
Thx, looks interesting.
Unfortunately with a PE version, I cannot open this document, is there any guides that describe the use of the extension from scratch?
Hello Brian,
Very nice work !
I'm beginning with Qv and I can't explain why the map doesn't load ( as you can see on the sc).
Have you an idea?

Before going any further, I'd suggest you download the latest version of this. I combined this map with one of my other maps and began storing it on github. YOu can download it with the "download ZIP" button:
Hello Brian,
Everything is running perfectly ...
Thank you so much for your extensions.
Hi..
It's very good extension. But i have a question.
I created the floor plan using autocad tools ( dwg extension). I need to transform this file into KML extension, okay?
I tried transform this file with some online tools but none of them could transform the file as described in Openlayer quick guide. Someone can help me?
Some other solution is possible? With other extension?
Thanks

Hi Brian, I have Qlik 9.00 SR6...I have checked GeoQlik which requires at least Qlik11 and from I have read also your plugin need qlik11...do you know if and how (even programs to be paid as GeoQlik) is it possible to have it on a Qlik 9.00?
