3 Last Lecture Map Projec+on: you learned about different type of map projec5ons, map scale, coordinate system What kind of distor5on occur a[er different projec5on process. Datum and Coordinate Reference Systems Basic program of projec5on transform.. 8/25/14 ITS488 3

4 Today s Outline Exchange of informa5on has become a crucial factor thus interoperability of GIS technology with other technologies is very important. We will learn what is Geospa5al data standardiza5on, development process, and how to implement it. We will see some good examples in this session. 8/25/14 ITS488 4

5 What is Data Standardiza5on? Data standardiza5on is the process of achieving agreement on common data defini5ons, representa5on, and structures to which all data layers must conform. 8/25/14 ITS488 5

11 So again, what is an open standard? A document, established by consensus and approved by an official organization, that provides rules and guidelines, aimed at the achievement of the optimum degree of order (interoperability) in a given context.

OGC Standards The OGC develops geospa5al standards that tackle interoperability: We can't share maps on the Web. We can't deliver data to different systems.

17 OGC Standards The OGC develops geospa5al standards that tackle interoperability: We can't share maps on the Web. We can't deliver data to different systems. "We don't have a common language to speak about our geospa5al data or our services. "We can't find and pull together data from our automated sensors. We have security issues rela5ng to geospa5al data exchange. 8/25/14 ITS488 17

18 Some resolutions based on OGC input Any OGC Domain Working Group can be made public ( , twiki, etc).

22 OGC s Approach for Advancing Interoperability Interoperability Program (IP) - a global, innovative, hands-on prototyping and testing program designed to accelerate interface development and validation, and bring interoperability to the market Rapid Interface Development Standards Setting Specification Development Program Consensus processes similar to other Industry consortia (World Wide Web Consortium, OMA, OMG, etc.). Outreach and Community Adoption Program education and training, encourage take up of OGC specifications, business development, communications programs Market Adoption Copyright 2009, Open Geospatial Consortium, Inc.,

23 Interoperability Program Major Benefits To Sponsors Ability to Determine Market Interest -- OGC s RFQ / RFT process validates the willingness of industry to address specific interoperability issues requiring new standards Rapid prototype development yields workable interface specifications in 4-6 months vice years for traditional standards processes Vendors test, validate and demonstrate interface integrity by implementing candidate specifications in their products (reduces the risk that a proposed standard will not perform as intended) Accelerated process encourages rapid time to market for Standardsbased solutions OGC member vendors are typically early adopters of new specifications Copyright 2009, Open Geospatial Consortium, Inc. 23
