I have a vectorized land cover map over a city. To start with I would like to separate the parks, de problem is thet, for example, the polygon that shows the open area of the park also stretches into the built up area.

 

I guess I have to create new polygons that follows the correct borders of the park. Is this the easisest thing to do? And how do I do that the easiest way. It´s a pretty large city with a lot of parks so there will be some polygons created.

 

The second thing i wanna do is to distinguish the parks that are larger than 1 hectare. To do that I guess that all the park polygons will be in the same shapefile where i calculate geometry for each park and.. well i guess i figured it out as i wrote this :) Are there any other ways to do it?

 

Regards!

Maybe you could start with stating what software you have at hand... ?

oups sorry...

 

So you are saying that the polygons for land cover have overlaps? I guess you have to inspect the data and decide if the overlaps should be classified as either park or built-up, right - and then either cut off the overlaps or keep them.

 

The second part is quite straightforward, as you describe it.
