[mkgmap-dev] splitter r585 ; dem-dist 3342 or 3314 ?

Thu Jan 18 09:53:30 GMT 2018

Hi Thomas,

oops, sorry, 3342 was a typo, should be 3314  ~ 2^32 / (360 * 3600) and 9942 ~ 2^32 / (360*1200)

Gerd

Hi Gerd, in some posts are written different -dem-dist . Which is the right,
3314 or 3342 ? For using with --align-for-dem  1" hgt ?
