Thank you, Ticker. I was able to run this program w/o issues even on Linux (via wine). Statistics tab gives quite a shallow view, it is not able to answer questions like: - am I saving any space if I don't include "name" in the point (restaurants without name)? In other words: how much data is used for labels or other attributes. Does it make any sense to use shorter labels or group them (pizza foo and pizza bar becomes "pizza" - will it be reused?) - How many kBs is taken by 50000 footways or 1000 polylines. The count itself is not really helpful - Is there any padding involved so it makes sense to make labels shorter just "enough" to not waste a single byte - Other statistics - data cannot be exported easily (even via clipboard) That means it's still going to be a lot of trial & error (if I do this - am I getting a smaller output and by how much?).

Hi Jose
GPSMapEdit from
can tell you some of this. The free version should do; install it and open gmapsupp.img or an individual tile. Then look at Map Properties > Statistics tab.

Hello, can someone recommend a way how I can learn more about what the detailed statistics in respect to the byte size of each element in the map generated by mkgmap? What I am looking for is something like: - lines: 3.2 MB - road_class 0: 1.3 MB - road_class 1: 1.2 MB - road_class 2: 0.3 MB .. - points: 1.0 MB - symbol 0x2c04: 0.3 MB - symbol 0x4c00: 0.2 MB Not sure if it makes any sense but the rationale behind is having an tool that would provide some hints as to which map details can be sacrificed when trying to cover the largest area of the map.
