Hardware & Workflow Dilemmas • Cost of Storage/Distribution • Server space for imagery alone an estimated $30,000+and were still unable to deliver their full repository of data. • $250,000 -$300,00 increase in Server investment and licenses to deliver full repository. • Not able todeliver data to 3rd party applications: AutoCAD, Microstation, ERDAS, Flash, etc.
Hardware & Workflow Dilemmas • Time Spent on Installation/Management • Took 3 weeks for each County year to load (2003,2007-12). • Took months to load all data, with no guarantee when loaded it would work. • With current setup, they could only deliver ONE year data online. • Lower Budgets • 10% decrease in the Property Appraisers budget for 2012. 147 Days to load imagery into other storage solutions.
