Just started using ArcMap - is this kind of analysis possible?

[ElioD_Aversa]

I have 2 files, a shapefile (.shp) and a raster file (.tif). The .tif is merely 2 bands (0 and 1) where 0 represents no forest loss and 1 represents forest loss (file is from here: http://earthenginepartners.appspot.com/science-2013-global-forest/download_v1.1.html) The .shp consists of polygons that represent protected areas (file is from here: http://www.protectedplanet.net/).

What I'd like to do is try a statistical analysis that would simply tell me how much forest loss ("1" points in the .tif) lies within the protected areas and how much loss lies outside the protected areas (in the .shp).

I'm wondering if it's possible to do this in arcmap/arcgis and if so how would I do this?

Sorry if this seems like a stupid question, I haven't been using the software for long and I couldn't find anything online.

Good point, I'm running on little sleep and so wasn't really thinking, sorry. I just uploaded it to mediafire i hope this works: http://www.mediafire.com/download/aaaluh55bo86d6m/loss_0n_60w_shapefile.shp

Thank you sir

Urm, yeah, you only uploaded the .shp file. ALL the different files are needed to use this in ArcMap. Can you zip them all up together and try again? There should be 5 to 7 files, all with the same name.

[ElioD_Aversa]

Ah I didn't realise, my inexperience really is showing now... you'll have to forgive me. Hopefully this is what you need: http://www.mediafire.com/download/9y2ofx4n5da636t/loss_0n_60w_shapefile.zip

Don't worry about it--common rookie error

Elio, what is the area you are interested in analyzing? This raster is 10x10 degrees. That's quite a large area of the earth.

[ElioD_Aversa]

I am trying to analyse as much area as I can, do you think 10x10 is too large? Originally I was planning on analysing the whole earth but I can now tell that is not really possible to do all at once

[SepheFox]

Well, I would say, yes, the whole earth is too large. You could work toward that, but you'll need to do it in chunks. So then the question is, what is your first chunk? You need to define the area of analysis, otherwise "outside the protected area" has no meaning, you see what I mean?

[ElioD_Aversa]

Ok so to start off with maybe it's best to just look inside the protected area? Is there a way to sort of get a number showing how much loss there has been within the polygon?

Then perhaps I can create a polygon that covers the rest of the area and do the same for that.

[SepheFox]

Yes, I will do that, and then tell you the steps.
