GIS: Geographic Information Systems
 The City’s Geographic Information System (GIS) is a computerized intelligent mapping system composed of maps, data, and the tools to create, manage, analyze, and display these maps and data in a variety of ways. The GIS Department is responsible for creating and maintaining this system, as well as for seeing that the system is used to benefit Derby in as many ways as possible.

Some of the features included in the City’s GIS include:
Basemaps Features:
Parcels, street names, ward boundaries, USD 260 boundaries, plats, addresses, city boundary, aerial photos, zoning, flood zones.
Infrastructure Features:
Sanitary sewer system, water supply system, streets, parks, storm water sewer system, traffic signals and signs, sidewalks, city facilities
Public Safety Features:
Siren locations/coverage, vehicular accident data, police citation data, crime data
Once features have been created in the GIS, maintaining those features and data in the system is a never-ending process. One example of this is in keeping up with the City’s growth. As the City continues to grow, the City boundaries must be constantly updated, parcels from new plats must be entered, and the new infrastructure to serve those new developments must be added. Maintenance records for much of this infrastructure are also recorded in GIS. Another example is entering the data received from the police department. Crime, incident, and accident statistics must be entered in GIS on a continual basis so patterns and trends can be studied in a timely manner.
With a powerful and properly maintained system, GIS staff is able to provide a service that enables City personnel, officials, the public, and others to make more informed decisions without delay.
Some of the GIS services include:
- Creation of new ward boundaries to better represent the Derby population.
- Providing builders with information such as where a new house is to connect to the sanitary sewer system.
- Tracking and planning maintenance and repair of various City infrastructure.
- Tracking and analyzing crimes, incidents, accidents, and citations.
- Use of storm water system maps to help meet regulations as required by the EPA’s National Pollutant Discharge Elimination System (NPDES).
- Provide information to assist with the planning of proposed developments and improvements.
- Provide maps for Derby’s website.
In the future, GIS staff plan to provide interactive maps that allow users to produce customized maps to better meet their needs.
