Sorry I missed your response! I haven't checked my channel for awhile. Yes, sort of. The "multiplying of booleans" (or the "AND" statement) is the closest conceptually to an "intersect" in the vector data model. The "addition" is actually closer to a "union" in the vector data model.

Hey Benjamin! In the last example - can you help me with the expression to it? how does one add up multiple layers? adding two seems to be easy but adding three or more is more comples. Im doing the Multi Criteria Analysis excersice - I followed the setps in the moduel and reclassified the criterion to 1s and 0s - so all I have to do is to use the Raster Calculator and write an expression that finds all the areas with a value of 1. So how does one write such an expression? I used the Boolean AND on two criterion and it worked but it does not work when I use it on all my criterion. Thanks in advance!!
Hi there! I'm so sorry to have missed your comment, I've been busy with other work and don't always get to checking my channel. If you still need help, feel free to contact me and we can Skype or something. www.rhumblinemaps.com It seems like you're talking about doing things that might be better explained in this video: th-cam.com/video/I-LQznw4qH4/w-d-xo.html or perhaps this one: th-cam.com/video/UD8Jjoo2B3s/w-d-xo.html Good luck!
Thanks Benjamin
Is this the equivalent of the intersect tool used for vector data?
