Abstract:A GIS-based online portal was developed to store, analyze, and display data from multiple sources pertinent to the ALDOT Coliseum Boulevard site in Montgomery Alabama. These sources comprise various consultants involved with the site including geotechnical companies, water testing labs, law firms, and management personnel from ALDOT/ADEM. The goal of this portal was to centralize information into a single location for easy access by all of these groups while also consolidating a number of activities in relation to data collection, verification, and preparation. The culmination of these goals resulted in a data-driven web map. The web map is able to display the numerous monitoring points and regions related to the site. On selection of these locations, the web map presents associated data and documents for download. In a similar manner, the property owner’s parcels associated with the site can be selected and legal documents relating to that property displayed. For more robust data retrieval, there are several tools capable of querying data based on multiple locations, location types, and constituents. The Search Documents tool can perform similar functions for ascertaining files based on their type and associated location. Any data and documents can be uploaded to the portal through one of two easy to use tools. The Upload Documents tool allows users to upload a file and input related information into several fields for future acquisition. The Import Data tool accepts comma separated value sheets for well specific data like lab testing and groundwater elevation data. The lab data uploaded to the site is put through a verification process before final import to the database. Several other layers can be toggled on and off on the map as well such as groundwater velocity and elevation contour maps. These features contribute to a streamlined and unified environmental site management process
