I am completely new to ROS. Without a massive amount of reading mostly in the wrong directions, down rabbit holes, I want to distill the essential details of how to solve this problem below.
1. Create a 2D indoor map using LIDAR of a building in realtime as per many examples on youtube.
2. Create on that 2D generated map another coloured heatmap of a Wifi signal from wifi access point(s)
Neither of these problems are new science both have been individually achieved in this or other domains. But it seems to be exponentially difficult to find out what packages are required and how they interact in ROS. I would like to build over a 2D generated map, a heatmap of RSSI signal from a given BSSID. I am not sure where to start. The weakest link is the Wifi mapping part. I have loaded up kinetic, the one heatmap program I found is for jade I now discover. I have no idea where to start or how to decompose this in ROS due to its messaging mechanisms and many sub component libraries and apps. I could start on the 2D mapper but that seems a well worn path with many examples. It appears there are many libraries that are combined to move a robot, I have at this point no desire to move any robot just the 2D mapping and heatmap only, so I cannot figure out what subject matter is noise related to robot movement topics and what is not. Can anyone point me in the right direction? Like use this package, ignore these components you only need this or that? It would be much appreciated.
