interactive instruments is committed to the application and propagation of open standards. We are one of the leading contributors to the development of open standards for sharing spatial data on the Web. Based on this foundation, we design and implement solutions for our customers and provide products for such solutions. ldproxy implements several of the new OGC API standards, which are also increasingly supported by ArcGIS. ldproxy is avalable under an Open Source license and an OGC Reference Implementation for OGC API Features. XtraServer offers a configurable software suite for providing geographic information using OGC Web Service standards like WFS and WMS in a highly efficient way. XtraServer is also available as an ArcGIS for Server Extension.
