I am interested in taking address data and converting it into longitude and latitude data in order to display concentration on a heat map. I have done some research and have found a few products that I can do this with. I'm wondering - what are the newest and best products available to do this? Does anyone have recommendations? Also are there any free ways to do this? Thanks.
IMHO the best solutions are from Qlik's partners. Some of the geospatial ones like GeoQlik, Analytics8 offer the most flexibility. There are other good ones too on http://market.qlik.com.
For 'free ones' you could go for a trial with one of the partners or find an extension that someone has already written. There is a new site that Qlik hosts for extensions called branch.qlik.com. You may find some there as well as github.com and here too (community).
