Hi there,

I am working on a system, where the bathymetry does not exist in Ocean Data View. I have the bathymetry data, but I would need to turn them into a shapefile to then use it in ODV.

How can I make a shapefile out of a set of coordinates (lat, lon) and depth? I have about 400,000 data points..

Thanks for your help!

Louise

Hello! My field of science is oceanography. I would like to basically map the bathymetry that I have into a shapefile contours, to then import it into another software. I am a beginner on matlab, thanks for your patience.

Louise, my experience with ODV is limited--what can you do in ODV that can't be done in Matlab?

Hello,

I was wondering if this was possible WITHOUT running it through a for loop? I make MANY shapefiles and have recently been writing them using MATLAB but they take FOREVER when they contain around 10,000 points. It takes less than 5 seconds to actually compute the data but then about an hour writing it to a shapefile. Avoiding a for loop would be wonderful.

Thank you!
