Calculate Length (Meters) of Unprojected Line Feature in Model Builder

[BenGrod]

Any suggestion on how to calculate the length (meters) of a feature class (line) which is in GCS_WGS_1984. Calculating the Meters field based on Shape_Length results in the decimal degrees distance. I could project the feature class, calculate area, join back to the original feature, and calculate the meters but I was looking for something cleaner. Is there a way to define a projection temporarily within Model Builder then calculate area? Thanks in advance for your suggestions.

Hi Ben,

Take a look at the Add Geometry Attributes tool.

Thank you Jake, speedy response and works perfectly!

Alternatively, you could project the dataframe. And calculate geometry (length) using the projection system of the data frame in the attribute table.
