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.

ISO 19130- The Editing Committee

• The editing committee was formed to edit the CD.
• Doug OBrain 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).

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.

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
  couldnt attend the Orlando meeting, and told
  them that I have enough resources to continue as
  the project leader until the project is finished.

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.

SeiCorp Proposals

• In Julys 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 todays 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

Clause 6 Georeferenceable Dataset

• Define the minimum content, components of the
  content, and relationship among the components of
  a IG 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

• 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

  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,
