OpenSeaMap-dev:Catalogue of INT Charts

Basics

• Catalogue of INT Charts
• Test charts: OSeaM_INT-1463
• github: chart-sheet-properties

Issues at github:

• Desired format
• Set up scripts to generate INT charts in various formats

Tools:

• pdf-converter Nitro Pro 9 works verry well on WIN (30days trial):
  After conversion to .xlsx, save as .csv and continue with text-editor to get rid of joined cells...
• PDF2Table does a very good job and is Open Source. It's producing a file output.xml containing the table information.
• coords transformation dd°mm.mm' to dd.dddd openoffice-calc example (Gebietsschema 'Deutsch (Schweiz)' wg. Dezimaltrenner!):

=WENN((RECHTS(N2;1)="W");(LINKS(N2;FINDEN("°";N2)-1)+WERT(TEIL(N2;FINDEN("°";N2)+1;LÄNGE(N2)-2-FINDEN("°";N2)))/60)*-1;(LINKS(N2;FINDEN("°";N2)-1)+WERT(TEIL(N2;FINDEN("°";N2)+1;LÄNGE(N2)-2-FINDEN("°";N2)))/60))
