hello,
I have -only- laser scanner and i can create maps with both hector_slam and gmaping(with help of laser scan matcher).
I wonder that, when it comes to mapping (or localization), how can i compare hector_slam and gmapping?
yes. you can try to make two map, and you will find difference. hector_map just only can afford indoor use, if you are outdoor, the map is too small, and it cannot expand. gmapping has no such limit, used indoor and outdoor, but a little Inferior to hector_map in effiency.
drawing efficiency means that how quickly and how correct the map is drawed. you can change the map update frequency to high to see the difference between the two mapping method.
memory usage you can use linux command, such as: topfree to monitor the memory usage.

I don't think anyone other than you can answer this question. You would need to first define what your performance metric is (speed, accuracy, map quality, ...) before trying to find how to compare the two.
since i dont have a robot, i cant choose speed as a metric...actually, it can be anything to compare (i need a comparsion no matter what) :) it can be accuracy, map quality or something else. but i dont know if they are comparable and how to do so?
