Gis non habitat shapes

[FERNANDO CESAR CASCELLI DE AZEVEDO]

Dear all, 

I was wondering if anyone could help me with a tutorial about how we can exclude areas of non-habitat of a habitat mask using a polygon from ArcGis (in arcGis or in Rstudio)?

I have a shapefile of my study area that, besides Atlantic Forest, includes several lakes that I would like to exclude from the mask (non-habitat areas) to estimate puma density. I have the shapefile of the lakes as well. 

Thank you in advance.

Fernando

Hi Fernando,

You can use the erase tool in arcgis with the input of your mask layer and the lakes layer to erase that area. I haven't used this mask with holes in a secr model before so I'm not sure if you will have any issues at the moment of analysis.

Best,

Matt

The Erase tool should do it
