Esri will host a live training seminar this week that demonstrates how to easily develop Web mapping applications using the new, no-cost ArcGIS Viewer for Flex. Introduction to the ArcGIS Viewer for Flex will air Thursday, September 23, 2010, on www.esri.com/lts. Sessions will begin at 9:00 a.m., 11:00 a.m., and 3:00 p.m. (Pacific daylight time). ArcGIS Viewer for Flex is Esri’s ready-to-deploy, configurable client application built on the ArcGIS API for Flex 2.1. The viewer can be used to create customized geographic information system (GIS)-enabled Web mapping applications without doing any programming.
