Standards Stuff

Open Geospatial Consortium releases spatial data quality survey. CAPE-OPEN gets industry backing.

The Open Geospatial Consortium has released the results of its spatial data quality survey. The survey, of several hundred GIS professionals around the world, is intended to guide the OGC’s development of geographic data quality metrics and a spatial data quality model. Following a laborious investigation into participant’s company type, location and industry the survey investigates how more accurate or more consistent spatial data would help organizations and if data is considered fit for purpose. The sections on data quality and management appear to have been answered by respondents but are frustratingly incomplete. However we did learn that 56% of respondents have no standards for data quality and 52% do not list data quality as a requirement in their contracts. Even more worryingly, some 25% of the sample said that they would not be prepared to pay for assured data quality levels in their contracts. The (incomplete) survey results are a free download from


Michel Pons who heads-up the CAPE-OPEN organization reports ‘major progress’ in CAPE-OPEN implementation and support from vendors including COMSOL, ProSim SA and SimSci-Esscor. The CAPE-OPEN standard promises ‘plug and play’ interoperability of chemical engineering applications used in hydrocarbon process modeling. COMSOL Multiphysics V 3.5 features a CAPE-OPEN thermodynamic and physical properties interface enabling exchange of property calculations with other compliant packages. ProSim also has a CAPE-OPEN interface for its Simulis Thermodynamics package—available as an Excel plug-in, a MATLAB toolbox or dll. Interoperability has been demonstrated with COUSCOUS (AmsterCHEM) and Xist (HTRI). Invensys Process Systems (IPS) has participated in the development of CAPE-OPEN standards and implementations. PRO/II 8.2, released in July 2008, heralds improved CAPE-OPEN support, achieved through a close working relationship with the CAPE-OPEN Laboratories Network (CO-LaN) and customers. IPS has participated in several CO-LaN special interest groups and is working to extend CAPE-OPEN with new interfaces for refinery reactor simulation.
