For creating a Point map, you will need a table that contains Latitudes and Longitudes. Check out this video.
For creating a Heat Map, there are multiple options.
1. You can use an extension to build such a map. Here is one of the extension

This is Trey with the QlikMaps team from Analytics8 (QlikMaps.com). First, I apologize for not getting back to you sooner. We get most of our QlikMpas related questions from our support portal (support.analytics8.com) and I have not done a great job of monitoring the community for such questions. That will change now as I'm going to put much more effort in to monitoring the community for such questions.
Now, to answer your questions, HeaMaps are available through a check box in the layer control on a points map. No configuration necessary. Simply select the Heatmap option and the visualization will change. For additional questions, I'd recommend checking out our Knowledge Base at QlikMaps.com/docs and login with your QlikMaps login.
