Part Three: Sometimes our GIS labels need a little extra info. to help avoid confusion.
In today’s installment, we will review the Concat() function. Concat is short for “Concatenate” which simply means it is a tool that helps us group things together.
This can be a very powerful tool (especially when it comes to GIS data) to help make our annotation more “readable”. In other words, if our data contains a numeric attribute value that equals 123.45 and we add that value to a label, what does it represent? Sometimes when looking at the data in context to the model geometry it is obvious. Other times it may not be.
For example, when looking at 123.45, what are the units? Does it represent an area or linear measurement? Perhaps it is a cost.
Often times, adding some additional information in front of our label, after our label or in both places makes the annotation more readable and can greatly reduce the chance of confusion. (i.e. “Area = 123.45 Square Meters)
Check out the video below to see how easily incorporate additional text into your GIS labels using the Concat function.
