How does Maplex for ArcGIS save me time?
By placing more labels properly the first time (automatically), you will save the time and expense of editing overlapping labels, adding missing labels, and repositioning labels.
I just make parcel maps, not atlases. Can Maplex for ArcGIS help me?
Absolutely. Maplex for ArcGIS provides many options for placing complex text and labels inside polygons. Maplex allows you to make the parcel maps that you need without having an operator create separate annotation strings for each parcel. By saving annotation to the database as feature-linked annotation, you only have to create labels once.
