The Open Landscape of Geospatial Information: Open data, open source, open standards
Presented at ASPRS GeoTech 2013 conference: http://www.asprspotomac.org/geotech2013/
Abstract:
The many dimensions of "open" provides users with higher quality geospatial information. Open Standards ensures interoperability to information whether its served by proprietary or open source software. Open Source software benefits the development of open standards and leads to a business ecosystem that includes more providers, more partnerships and more customers.[1] In the end the user does not care if the code is open or proprietary. Users care about access to data and the quality of the data. Open Data has advanced with the recent policies from GEOSS Data-CORE [2] and the US Open Government Initiative [3]. Open Earth Observation data from government sources benefits industry and users. Open standards, Open source and Open data can result in higher quality information. The fusion of data from multiple sources results in higher quality. Fusion is possible based on multiple data sources that can be interrelated [4]. Improving Data Quality through knowing the uncertainty and the provenance of derived information is dependent upon an open landscape of geospatial information.

14. Where such standards exist, EarthCube should use formal, internationally
approved, geoscience-wide data access/sharing standards and protocols
(e.g. ISO, OGC). (v100 R2)
Where there are not formal, international standards, please indicate your
priority between, on the one hand, EarthCube encouraging development or
extension of formal, internationally approved, geoscience-wide data
access/sharing standards and protocols (0) versus EarthCube have its own
systems of standards and protocols (1). (v101 R2)

15. Why Open Standards?
• Prevents a single, self-interested party from controlling a
standard
• Lower systems and life cycle costs
• Encourage market competition
– Choose based on functionality
desired
– Avoid “lock in” to a proprietary
architecture
“People want government
to be transparent, so why
shouldn't the technology
be?”

• Stimulates innovation beyond the standard by companies
that seek to differentiate themselves.
