update the map_server
Does anyone know a way to update the map that map_server uses? AFAIK, the map is set to the contents of an image file as soon as the node is launched, then remains static for the life of the node. My situation is as follows: I have two nodes this job mapper and map_server. Mapper records ultrasonic range measurements into a png file, and has a service for saving updated versions of the map. How can I push updates of the map to my map_server node?? Will I have to relaunch the map_server node every time? Thanks
