Thumbs up Navionics App Markers.db

HI All, good day, need some advise on Navionics apps i have list of coorindated to import into Andriod navionics apps, i managed to find the location to import the Markers, however the market format are as such x and y axis, i have googled over the world find no clue how to convert this numbers to decimals degree vice versa.

Below are the sample wonder if anyone knows how this is being compute?

IN Navionics markers.db shows
x = 11539022
y = 358835

the decimal degree for this location is 3D14.603' 103D39.163' where D=Degree

Hope someone can assist to solve the mystery.

I have hundreds of markers to import i can't be scrolling the points one by one. Also it would be use for future export if need to change system

Just to share if you would like to export the navionics markers, you need to have root access, then proceed to /data/data/it.navionics.xxxxxxxx version you are/database markers.db. Also please do take note on the permssion is rw rw ---- and also the owner permission must follow the markers-.db-jounral when you replace the marker.

Hope got some clue.

Re: Navionics App Markers.db

Woods Hole has a little utility to make the conversion: Coordinate Conversions but you have to know the origin that Navionics uses for their charts in the X-Y plane. Maybe an email to customer service could solve it? They are usually super helpful
