Labeling features can be a time-consuming part of creating a map. When you’re dealing with many features, it may seem downright onerous. But there are ways to make the job easier. Consider this illustrative tale.

Week 1: James—smart, ambitious, new on the job—is designated the department map maker. Sam, data technician by day, ink artist by night, tells James about a new dataset with a thousand or so point features that will be used as an operational layer in several high-profile maps produced by the department. The data will be updated weekly and the maps need to be in sync (Sam also suggests a warrior armband to command respect from Marc, the alpha analyst in the group).

In ArcMap, James adds the point layer and turns on dynamic labels, spends time creating label classes and setting scale ranges and formatting the labels in each class appropriately for the map products. He converts the labels to a standard annotation feature class stored in the same geodatabase as the point feature class so the annotation can be reused easily on multiple maps. He then spends several hours painstakingly positioning the annotation until he’s satisfied the map text looks perfect.
