Hello everyone, it might sound as a stupid question, but I can't figure out a solution. When I assign different symbols to different categories, how can I select or unselect some of them to be or not to be shown on the map? Example: in the attched image, I would like to unselect a category (for example Capreolus) to not see it on the map. How can I proceed?

Hi, I used identity (but I also tried with intersect and it's the same). Instead of getting a new polygon with its area in the attribute table, I get this: I need to know the area of the intersect...

Got it. I have another problem. My shapefile "griglia4x4" is like this: while I need it to be only one polygon, with only one area. How can I trasform it?

Hi Darren, thank you for replying. I can use Identity. How would you proceed with it?

Hi everyone, I have a polygon (.shp) and a shapefile (.shp) and I would need to calculate the percentage of the polygon overlapping with the shapefile. Someone suggested me to ude the Intersect function, but I can't figure out how. Could someone tell me how to proceed, step by step? thank you in advance! Nebbiolo

Hi Xander, thanks a lot for your reply I attach you a screenshot to be clearer. This is the situation: in short, I have a .shp and a dtm. Coordinates are X_UTM and Y_UTM, they are in a normal excel file at the moment. I am using ArcMap in ArcGIS Desktop 10.6. I got the student edition ArcGIS Desktop Advanced (Single Use).

I have: - a big map of my country - a shapefile with a "reference area" - several coordinates to identify some points I should: - put the points on the map - draw the minimum convex polygon for the points - find the percentage of the MCP included into the reference area. Could someone help me explaining step-by-step how to proceed? I guess it's really easy but I never used ArcGIS before. Thank you in advance Nebbiolo
