[mkgmap-dev] Problem with aeroway=aerodrome as a relation

Hi Gerd,
assisting Nelson, using the default style we have ever encountered the first problem is the style does not look landuse = grass forcing us to include in inc / landuse_polygons line landuse = grass [0x17 resolution 20].

Using the default style (with grass included) we only have succeeded using the "comment out" in the following polygons lines of "default style":

:# aeroway=airport [0x07 resolution 20]
# aeroway=aerodrome [0x07 resolution 20]

Hi Nelson,

there is no special java code in mkgmap to treat aeroways.
I guess you don't use the default style, so I can't say what goes wrong.
A good tool to find out what mkgmap writes to the img file is
Use it to open the corresponding img file and double click into the area
you want to analyse. It shows you what Garmin type the area has.
Press escape to close the dialog box followed by
delete to remove that polygon. Repeat this process until GPSMapEdit 
shows something like
"Area of map coverage (0x4b, polygon)"

If you do this for both img files (the good and the bad one) you
should be able to find out what's different.
