Updated planimetric data added to GIS

​Within the GIS, manmade features such as buildings, bridges,
railroads, and roads are classified as planimetric data. The city
contracts with Ayres Associates to update planimetric features for about
twenty-five percent of the City each year. This ensures that none of
the base mapping within the city is older than 5 years. Updated base map
layers are important to ensure that new construction and redevelopment
area are accurately reflected in the base map features.

The base map layers are used to evaluate existing conditions and plan
future updates. By having current layers, the City is assured they are
making the best and most accurate decisions. Accurate base mapping is
only one of the ways that GIS assists the City with making good
decisions.
