hi,
i need to read .kap file for writting vb.net app.
i found information about header .kap files at :
https://github.com/ngacharts/ngachar...r-and-bsb-file
but some mistake?
REF field give reference point from x,y image position to geoposition (index,x,y,lat,lon)
but in some kap file i found that :
REF/1,7752,754,43.666666667,5.216666667
REF/2,7770,11463,41.233333333,5.216666667
REF/3,315,11502,41.233333333,2.916666667
REF/4,297,793,43.666666667,2.916666667
i've got same longitude (2,91666) for different x pos 315 and 297.....?
Opencpn give me the right position how he do it that?
my kap file are official files from SHOM
charts and GE2KAP files generated
I've only right pos with
opencpn kap files
anothers things :
numer and order of REF fildeds are not fixed ?
and what is exactlly PLY fileds ?
Thanks
