Business Problem Solved

Decatur faced fragmented data systems, limited GIS staffing, and increasing demand for accessible, real-time information across departments and the public. Critical workflows like infrastructure management, planning, and citizen engagement required more efficient tools and centralized data. InterDev addressed these challenges by standardizing GIS data, modernizing applications, and creating intuitive web-based tools and dashboards. This eliminated silos, improved data accuracy, and enabled departments to leverage GIS for coordinated decision-making while enhancing public transparency and engagement.

Technology Implemented

Decatur's solution is built on Esri’s ArcGIS platform, leveraging ArcGIS Online as the system of record and integration hub. Key technologies include Experience Builder for modern web apps, ArcGIS Hub for public-facing sites, ArcGIS StoryMaps for communication and planning initiatives, and web maps and dashboards for operational insights. The platform supports integrations with systems such as Cartegraph and enables continuous updates to base maps, MS4 stormwater data, and open data services. This cloud-based architecture ensures scalability, accessibility, and real-time data sharing across stakeholders.
