The name of each element is set to be the numeric type (and* sub-type for points).** This can be used to decode the type_id's.** Instructions for use: If you run this program with the environment* variables BASE_LAT and BASE_LONG set to something just SW of where you* are then the map generated will be located near where you are. Otherwise* the default location is at (51.7, 0.24).* Options --x-base-lat and --x-base-long have the same effect.** The map doesn't have a standard background and so flags have to be set to* say it is transparent. This is done in ./ElementTestDataSource.java** To run, something like:* java -jar mkgmap/mkgmap.jar --verbose --gmapsupp --order-by-decreasing-area test-map:all-elements** You can then use the find facility of your GPS to* show the near-by points.
