I would like to create a floor map which show foot print of user or heat map based on user movement on floor. I'm not sure how to create this heat map by using .dwg file. I also need to show this live map on my website which give real time data on map and show where users are more (currently I have only .dwg file which is auto cad file where i have complete drawing of my floor plan).
I'm open to use any technology which supports on website and can be used with JavaScript, PHP etc. Is there any tool which can create a heat map for me and generate web based format to host that on my website?
