  1. Briefing on ISO 19130 History and Content Liping Di Center for Advanced Information Science and Systems (CSISS) George Mason University ldi@gmu.edu

  2. Content • History of ISO 19130 • Action on reactivating the ISO 19130 project • Briefing on the current edited version of the document

  3. ISO 19130 History-Project Team • The spin-off project of ISO 19124 approved by ISO TC 211 in March 2001. • Experts from 11 countries and 5 organizations form the project team • Australia, Canada, China, France, Germany, Japan, Malaysia, Saudi Arabia, South Africa, Thailand, USA. • OGC, CEOS, IHO, DGWIG, and ISPRS • Project leader, Dr. Liping Di of USA and Editor, Dr. Wolfgang Kresse of Germany. • The project team produced the WD which was voted to CD in 2004, and project team was disbanded.

  4. ISO 19130- The Editing Committee • The editing committee was formed to edit the CD. • Doug O’Brain: Chair, and Liping Di: Editor • Members of editing committee from 14 countries and 6 International organization. • The CD 1 was passed as DIS in 2004, but the original project team & editing committee/working Group6 felt it is not perfect. Therefore the editing committee reissued CD2 in early 2005. • CD 2 was again passed as DIS. In the CD2 voting, we received about 400 comments. • The editing committee had a one-day meeting in Montreal in September 2005, but could not finish all editing work then. • The EC decided to continue the editing work through the on-line communities (WG6 forum, E-mails).

  5. ISO 19130- Time limit • ISO has a five-year time limit on a project to DIS stage. • In order to meet the time limit, the EC had to turn in the edited version of document by December 2005. • At that time, we had two choices, 1). rush in the document as DIS in December 2005, or 2). Make the document more perfect and re-introduce the project through NWIP which will directly vote the edited document into DIS. • The chair of EC decided to take the second option. • It is easy to reintroduce the project with a nice-edited document. • He thought that WG6 of TC211 can submit the NWIP. • The editing work was finished in March 2006, with edited ISO 19130 document, the juristified comments, and a NWIP submitted to ISO TC211/ WG6. • The edited version represents the consensus of experts in the project team and editing committee. • The ISO 19130 was officially deleted from the TC211 program of work due to passing the time limit.

  6. ISO 19130- Resubmit NWIP through US • The Convener of WG6 (also EC chair), talked to TC211 secretaries about submitting the NWIP through WG6. • Secretaries indicate that it is a rare case to do so. • The common way is through the country who originally provide the project leader. In this case, USA. • I and Doug have communicated with INCITS/L1 for submitting the NWIP through USA before May. • In May, GMU submitted the NWIP along with the edited CD and other documents to INCITS/L1 chair. • No action has been taken by L1 on this. • In May before the TC 211 meeting, I sent E-mail to Doug, Norman, and Charles to explain why I couldn’t attend the Orlando meeting, and told them that I have enough resources to continue as the project leader until the project is finished.

  7. ISO 19130-WG6 meeting at Orlando • The WG6 in Orlando discussed the status of • “Committee Draft 2 of 19130 passed its last vote with 15 YES votes and 2 NO votes, and 404 comments. An editing committee was held on September 12 which addressed approximately half of the comments including all comments that required a broad discussion. The editing committee continued on the WG6 forum and the disposition of comments and revised draft have been posted before this meeting.” • “Since the document has reached its time limit a NWIP for the resubmission of the document as a TS will be submitted by the US. US to provide Project Leader. W Kresse from Germany to be editor.” • “A future version of the document will include additional sensor information including that moved from 19101-2.”

  8. SeiCorp Proposals • In July’s INCITS/L1 meeting, the Chair circulated and discussed two NWIPs submitted by SeiCorp related to ISO 19130 on which SeiCorp will be the project leader: • The first one suggested a major modifications to the existing CD document. • The second one suggested a complete new work. • The chair issued a voting ballot for members to choose the option. • Discussions by INCITS/L1 members about the ballot resulted in a special INCITS/L1 meeting on August 22.

  9. Special INCITS L1 Meeting on August 22 • The decisions on this meeting: • Cancel the previous ballot on ISO 19130. • A team be put together to review both GMU and SeiCorp NWIP's and merge them into one cohesive document, which the INCITS L1 membership will review, comment on and have a new 30-day ballot. • The team will be headed jointly by Dr. Liping Di and Mr. Bill Craig.  • This is why we have today’s meeting.

  10. The Outline of the current version of 19130 edited CD-Sensor Data Model for Imagery

  11. The UML models have been harmonized with other ISO 191XX (e.g., 19115-2, 19101-2, etc) standards. • The Standard has also been harmonized with OGC SensorML

  12. Scope of ISO 19130 • This International Standard specifies the information required to determine the relation between the position of a pixel in image coordinate and its geographic location or map location for data derived from remote sensing – from spacecraft, aircraft, ships and remote ground locations. This information includes a sensor description and associated physical information defined by a sensor model, functional fitting between the image and geographic coordinates and ground control points. The logical association between the measurements and the geolocation information is described. • This International Standard supports direct exploitation or conversion of remote sensing observations into interpreted geographic information. It is applicable to data products intended for distribution, to specify what information needs to be provided along with the data. It defines the metadata to be distributed with the observation data to enable users to determine the geographic location of the observations, by describing a sensor model for each sensor class used to provide observation data. It does not normatively specify how the user will derive geolocation from this information, and it does not describe the format or content of the geolocated data the users generate.

  13. Outline of ISO 19130 • Nine clauses, three normative annex, two informative annex, and an introduction • Clause 1: Scope • Define what kind of geographic data is covered by the standard • Clause 2: Conformance • Define the way for complying with the standard. Conformance

  14. Outline of ISO 19130 • Chapter 3: Normative References • Specify the ISO/TC211 suite of standards that are applicable to this standard. • Chapter 4: Terms and definitions • Define terms used in the standard • Chapter 5: Symbols and abbreviated terms • Define the symbols and abbreviated terms used in the standard

  15. Clause 6: Georeferenceable Dataset • Define the minimum content, components of the content, and relationship among the components of a I&G data product. • The components include Instrument readings, Geometric, and Radiometric. • The relationship tells how to apply geometric and radiometric information to instrument readings. • Geolocation information include sensor and platform parameters, Ground Control Points, and/or fitting functions, which are defined in details in Clause 7. • Data organization: define the common data structures that hosts swath data.

  16. Clause 7: Geolocation Information • This clause defines four ways for providing geolocation information: • sensor model (7.2, 9.2) • Fitting models – multimodels (7.3) • Fitting models  simple functional fit model (7.4) • Ground control points to transform from the instrument system of a remote sensor to geographic coordinates (7.5) • Control points to transform between a digital image and geographic coordinates of a raster digitized product (8.5,9.8)

  17. Clause 8: Sensor types • Groups sensors into groups based on the mechanical and electric properties of sensors • Provide basic descriptions for each type of sensors. • Include Scan linear array, pushbroom sensor, Frame Camera, paper and film scanner, Radar, Lidar, Hydrographic Sonar.

  18. Clause 9: Sensor constitutes • Break the sensor types into common sensor constitutes. • Define those constitutes as classes. • A sensor model can be constructed by using those constitutes. • Provide flexibility to accommodate the new type of sensors

  19. Annex A and B • Annex A- Conformance test • Define the way to test the compliance to the standard. • Annex B –Geolocation information data dictionary • Define the terms used in this standard

  20. Annex C of ISO 19130 • Annex C: Coordinate systems • Define the coordinate systems used in the standard for gelocating the sensor readings to Earth location. • Two groups of coordinate systems defined or referred: • Image coordinate systems • Earth coordinate systems • Algorithms used in the transformation of coordinate systems

  21. Annex D & E (Informative) • Annex D—Coordinate Transformations • Annex E -- Example for geolocation using sensor model parameters.
