So, I essentially have a map of Greenland, which I have created and there are bodies of water underneath which i want to clip (so i want my map to be my square polygon of the land with some bodies of water 'cut out' essentially)
But i create my polygons along the bodies of water, and this error appears. I've checked other boards and i save my edits, I try and put everything in the same folder etc, nothing seems to help.
)this is university level stuff so not too complicated but i am very confused how to 'cut out' my polygons.)
any help is appreciated.
Hi, yep, here you go! i want my final product to look like the yellow, but i need to remove lakes, as i really am just focusing on the land terrain if that makes sense? i will eventually be calculating NDVI.
I just want to work out how to cut the bodies of water i dont want there out. apparently to do this, i have to use a polygon, but it wont let me clip it.
Extract by polygon.... there is a keep inside and keep outside option
You need the Spatial analyst extension however,
