The state of Rhineland-Palatinate, represented by the State Office for Environment, Water Management and Trade Control, contracted the companies terrestris and geomer mid April 2012 to implement the Spatial Data Architecture Water (SDA Water). You will find the related press release below: The state of Rhineland-Palatinate orders a Spatial Data Infrastructure focussed on water related issues based on Free Software Current software to be replaced by a modern system Bonn/Heidelberg, May 7th, 2012 The state of Rhineland-Palatinate, represented by the State Office for Environment, Water Management and Trade Control, has numerous water related tasks to fulfill: Flood prevention requires extensive coordination efforts, ground- and surface water needs to be managed in a meaningful way while areas for the generation of potable water have to be delineated. These are but a few of the numerous overall tasks. Due to the spatial character of the problems a web based, geographical information system (WebGIS) is being used. System evolved over many years The current system that grew over many years is now being modernised and transferred into an up-to-date spatial data infrastructure. The tried and trusted expert procedures are to be retained while the shortcomings of the current system are to be replaced by modern approaches. The state consciously opted to use Free Software components for this. Renewal based on Free Software In autumn of 2011 a europe-wide tender was put out seeking offers for the complete redevelopment of the WebGIS. In mid April the companies terrestris GmbH & Co. KG and geomer GmbH were awarded the contract, after being successful with an offer based on Spring, Hibernate, OpenLayers, GeoExt and other components. The geo database to be used will be Oracle Spatial. The services supplied by SDA Water can also be used in Desktop-Clients like ArcGIS from ESRI. Sustainable investment Due to the license the use of Free Software has numerous advantages:
