You can share a Layout for similar design of map output, but you cannot share the Map!

When I was creating the new map layouts I was using the original map of Ithaca. But then I realized today that whenever I changed the symbology or labeling properties or the data sets (polling locations, tax parcels, etc) for a specific layout, I was changing the symbology or labeling properties or what have you of the original map, thus I was changing the symbology or labeling properties or what have you for the other layouts that were using the original map (if I had polling locations turned on the original Ithaca map, polling locations would show up on all the other layouts). Was I supposed to generate a new map for every new layout? Quote from student’s question.

Every time when you create a new map, you start a new Map session in ArcGIS Pro! Otherwise, the new change you make will complete change the map you already made (you will lose what you have done). You can share a Layout, if your map design is similar.


If I use standard deviation classification, I am unable to adjust the # of classes. I can only have four classes at a time, what happens?

The number of classification with standard deviation is predetermined in the program. If you choose 1 standard deviation as the interval size, there are 4 classes. It is not practical to choose a smaller interval size because it gives more than 7 classes! Remember, the number of colored classification scheme is better not to pass 7.
