Over the past 5 years, Middlesex County, NJ has been creating and updating its underlying data layers to create an Enterprise GIS. Now the County is actively using GIS in day to day processes from capital improvement projects to asset management. The County created a web portal so that users can view, download and manage GIS data and applications from the County’s Enterprise GIS. Users can download data layers in multiple formats such as CSV, GeoJSON, Shapefile and FileGDB. The tiered log-in model allows administrators to manage data dissemination and monitor site activity with a robust dashboard showing metrics such as server status, data download frequency and availability. The dashboard also shows detailed metadata updated live from SDE layers edited by multiple stewards. Administrators can easily edit, update and add applications from other sites for easy viewing by the public on the front page. The interactive map also allows users to view, print and download spatial information. Technology for this portal consists of .NET, JavaScript, Bootstrap, and D3. This presentation will demonstrate the application and management tools developed.
