  • Choosing a web mapping system can be difficult and confusing. It seems like every week, there is a new technology that will be a revolutionary change forward. You can start with the most simple Google Maps based product, to full custom ESRI ArcGIS Server geoprocessing. The goal is to find a system that works with your existing workflows, but still gives your “customers” a product they can use. We will look at what makes a modern mapping system, what systems that are out there and what to consider when looking at these systems.
