NOAA: NauticalCharts.govSituationThe National Oceanic and Atmospheric Administration's (NOAA) Office of Coast Survey (OCS) provides mariners with nautical charts containing hydrographic data essential to safely navigate our nation's waterways. In the past, charts were printed in large quantities, warehoused, and sold through a variety of retail outlets. Dredging operations, cable laying, pier and buoy construction, and the like quickly made the charts inaccurate. Mariners were forced to manually update charts from OCS Local Notices to Mariners - a time consuming and tedious process. Furthermore, it was not possible for mariners to have data specific to their needs printed on the charts. SPS - Problem Solved. NOAA selected SPS to design, develop, implement, and support a "Print on Demand" (POD) system that enables just-in-time printing of nautical charts overlaid with current hydrographic data and information specific to a mariner's needs. This system became the award-winning www.NauticalCharts.gov e-government system, subsequently built and deployed in less than a year. Methodology Print-on-Demand was one of the first Government projects developed with the Rational Unified Process. SPS conducted interviews, facilitated sessions, and documented the results as Use Cases (using the Magic Draw tool). The Use Cases, dynamically maintained throughout the project, drove design elements, test criteria, and test cases. Excellent client interaction and guidance was greatly facilitated by the iterative approach and multiple production releases inherent in the Unified Process.
Using XML messages and FTP, NOAA transmits chart components and orders directly into the printer's ERP and chart production systems. Other product suppliers can elect XML, e-mail, or fax as the means to receive orders. Privacy on the e-commerce site is achieved using password protection to limit access to an agent's records. Persistent cookies are not used. Security is provided by password protection, and by an automatic session time out to prevent the use of an unattended logged-on computer. Automatic daily backups are made, and mirroring is available to limit the impact of a security breach. Security is further enhanced by hosting at a secure Internet service provider and by regularly applying security bulletins and software security updates. Lessons Learned Originally, SPS was tasked with just developing an ordering site for POD charts. As with many projects, "Scope Creep" quickly set in. We found ourselves increasingly involved with the process of locating and assembling the relevant digital files, and actually constructing the batch instructions for the print process. As with many projects, understanding the customer's business needs was key to success. Results SPS produced a system for our customer that was innovative and well received in several areas. Due to the then-unusual practice of tapping open source resources, we were able to construct a sophisticated, secure site for significant cost savings. Our customer estimated that they saved over 40% on the initial delivery cost by using the SPS approach. Similarly, the end users of the system (chart agents and commercial mariners) continue to switch to POD charts: over 1,000,000 charts have been ordered on the system since it was first put into production.
