GOAL: I want to find out how much land is agricultural/forest/urban/water/sand within 5km of a point.
WORKFLOW: (SEE IMAGE ATTACHED)
You can figure out the XY coordinates of the point in question by right clicking the point then hitting Identify. This will give you the coordinates of the point in whatever units were specified for the map. You can then enter these coordinates in the Extract by Circle tool to achieve the desired result.
Let me know how this goes for you,
Thank you for showing me how to find the X,Y coordinates. I just tried the extract by circle tool - input raster "MLClass_All_6" and the X,Y coordinate of the point, and the radius as 5000, and I kept the extraction area inside. I ran the tool, and it runs successfully - but nothing shows up.
I tried using that tool just now and the output generated was empty as well. Not sure what's going on with that. I did however find an alternative method for achieving the desired result. Try utilizing the Clip (Data Management) tool. Simply input the raster, specify that 5km buffer as the Output Extent, and be sure to check the Use Input Features for Clipping Geometry option. Running this should produce the clipped layer you're looking for.
One last issues to overcome! I need to calculate the area (in acres or some other form of area) of each category within the clip. I'm not sure how to convert the count in the attribute table (or if that is even what I should be doing) into area. I created a column for acres and when I right click it to use calculate geometry it is grayed out.
Never mind!! I figured it out! I just found the size of reach cell and multiplied that by the count and got meters squared. Then I converted meters squared into acres! Yes!
