Seatrace tiedostoformaatti

SeaTrace on oheisohjelma joka kirjoittaa tiedostoon paljon enemmän dataa mitä SeaClear. Tässä on tiedostoformaatti:

Yleistä

• Data in comma delimited text string
• All speed in Knots
• Lat & Long in decimal deg
• Other angles in Radians

Sarakkeet

Laskentaohjeita

• Saadaksesi asteita radiaaneista voit ainakin Gnumeric taulukkolaskentaohjelmassa käyttää =DEGREES(solun osoite) määritelmää.
• Saadaksesi solun Jn (J-sarake on apparenttikulma radiaaneissa) näyttämään +/- asteita: =IF(DEGREES(Jn)>180,DEGREES(Jn)-360,DEGREES(Jn))
