Is it posssible to perform any math on ESRI ArcMap dynamic text? For example I have the area of a SDE park layer's SHAPE.AREA, but it is in m2 because the layer is in NAD_1983_UTM_Zone_17N. I want to show the area in hectares (m2 / 10000). How do I do this? Is it possible to add two fields together and display it in dynamic text?
This from Jeffrey Barrette, an ESRI employee:
"No. Dynamic Text provides many different formatting options for dates, times, coord systems, etc but it does not provide the logic to perform mathematical operations. You would need to incorporate Python and then use arcpy.mapping to update text elements in a layout."
Open layer Properties and go to the Labels tab. Click the Expression Button. Type your calculation (Area/10000 in this case) inside the expression area.
Make sure that Labeling is enabled for this layer.
