Hello,

I have latitude and longitude data to plot coastal line of north america and then continent margin. As you can imagine this is going to be two irregular polygons where the coastline polygon will be placed within the continent margin polygon.

I want to plot these two polygons and calculate the area of land region (the area within inside polygon) using inpolygon function. I would truly appreciate if someone could help me with this.

thank you

There are Mapping Toolbox functions areaint and similar functions to do this. Those might be more appropriate. Follow the links in that and related documentation for other such functions.

The polyarea command is for calculating polygon areas.

You can also use polyshape.area.

Thank you for your reply.

There are some places where boundaries overlap. from what I understood this function colors those areas and calculate the total area of all those overlaps.
