proportion of different habitats in an area

Discussion created by jstruve66 on Dec 16, 2011
Good afternoon,

I would like to know the proportion of certain habitats in Tampa Bay (Florida). I have a shape file with the entire coastline of Florida and shapefiles that denote habitats, also for the entire coast. The proportion I am intersted in is the habitat area/bay area.

What is the best way to do this ? Should I define points around Tampa Bay and then "snap" them to the underlying coastline until I have a continuous line that defines the Tampa Bay area and then find the intersections with the habitats ?  Is it possible to create lines in this way ?

Thank you for suggestions,
