Thanks to everyone who helped with their experiences and solutions to my problems along the way -- Kismac is now doing great war driving in the Vancouver area and is proving to be exceptionally reliable and accurate. I have, in fact, found it to be exceptionally useful, and in many ways easier to use and less problematic than dedicated GPS software! Suggestions: [optionally] display other information (altitude, velocity) in the bottom bar, along with latitude and longitude allow us to create a list [table) of maps so that we can jump from one map to another fairly easily. This might be implemented as a "checkerboard" type of interface in which you click on a square, associate a map name with that square, and then you could easily jump from one map to another using a palette. Perhaps even automate it, when you move from one corner of one map to another... or even load the map automatically depending on the lat/long! [optionally] centre the blinking blue dot on the screen create a tutorial or help page to help people calibrate a map -- I volunteer to do this, if you like ...r
