GIS Day 2022

Today is Global Geographic Information System (GIS) Day! Let’s take a moment to learn a little bit more about GIS in Johnston from GIS Coordinator David Croll, who has served the City of Johnston since July 2005.

David works with all departments within the City and his day-to-day duties are never the same. On a daily basis, he creates and maintains data that goes into maps and infrastructure databases. He often has special requests for maps or information to help make data-driven decisions. These require him to delve deep into the City’s oldest records to determine what previous staff have approved or constructed in the field.

David uses old maps, records, survey information, aerial imagery and personal anecdotes to piece together information that some may call a puzzle. Essentially, he is trying to understand what issues are occurring and determine a solution for the betterment of the community.

David has seen a lot of growth within our community throughout the years, and his role is always changing, which is one of his favorite parts. Join us in celebrating #GISDay and thanking David for his service.
