Although this clip of my map is displayed on ArcGIS Online, I created it in ArcGIS Pro.
I drew this polygon of an estuary by tracing the shoreline from an aerial image. Then I separated the polygon into different zones (polygons) where volunteers will collect and track an invasive plant called frogbit.
For the analysis, I need to know how many square feet each of the zones are, but as you can see from my table, that information is not correct. Based on the scalebar the estuary zones should be more than 600 feet across in some areas, but the table shows shape feet, area and length in minuscule numbers which are less than a foot. Does anyone know how I can fix this to show true distances using ArcGIS Pro?
I appreciate any help you can offer!
I think this is due to the units of the spatial reference of the data. If the units are degrees, then it won't look like what you're expecting. Right-clicking a column in ArcGIS Pro (you can add the feature service to Pro), you will see an option to "Calculate Geometry". This also lets you choose which projection/spatial reference (and thererefore, units) you want the resulting calculation to be done in. If you pick a local projection that has the units you would prefer, you can ensure to get something useful. There is also a way using Arcade that will allow you to do a field calculation to get the result in your desired units.
Thank you, Doug. I will also try your methods and see what I come up with.
Those default Shape fields are calculated automatically by the database backing the data using the spatial reference of the feature class. In most cases they're completely useless and should be ignored. There's a few ways to get the proper area for a feature:
Give these options a try, you should find something that suits your workflow and requirements.
Thank you David!
I will give those a try.
