14 September 1997
| Issue | Responsibility | Action / Decision |
| Cambridge Meeting | Manning | Finalise record of Cambridge meeting to include comments from Sievers, Thomson, Mullins. |
| SCAR Bulletin | Clarke | Advise SCAR of corrections to the wording in the place names resolution, as published in Bulletin 126. |
| COMNAP Liaison | Clarke | Discuss COMNAP liaison issues with Jack Sayers, then write to SCAR and COMNAP to formalise arrangements. |
| SCAR Executive | Clarke | Continue to pursue regular meetings of SCAR WG Chief Officers with the SCAR Executive. |
| WG-GGI Executive | Clarke | Prepare and distribute record of actions and decisions from the Reston Executive meeting. |
| WG-GGI Web Site | Clarke | Arrange for update of WG-GGI web site to include 'What's New' (meetings, workshops, announcements, publications etc) |
| Santiago Workshop | Manning | Discuss proposals for Santiago Workshop with
Prof.Eng Victor Villanueva: dates, publications, attendance,
speakers, program etc. Advise Executive of outcome as soon as possible. |
| Concepcion Meeting | All | General structure of 1998 Concepcion meeting to
be: 1. Status reports from the 3 programs 2. Presentations from external parties 3. Plans for 1998-2000 (each program to hold an informal meeting, consecutively, then present and finalise scope and structure of projects in plenary session) Program leaders are to chair 'their' sessions, and to maintain notes. WG Chair to prepare official record (report to SCAR). Written reports to be requested for each project (for discussion in Part 1 of the meeting), and for each country (for tabling only). |
| Communications | All | Acknowledge receipt of all WG-GGI e-mails, even if detailed response to follow at a later time. |
| Project | Responsibility | Action / Decision |
| Permanent Observatories | Manning / Mullins |
Pursue upgrade of McMurdo antenna to VLBI with NASA Goddard Space Flight Center. |
| Manning | Write to all Antarctic permanent GPS tracker operators and request that data be routinely provided to IGS. | |
| Epoch Campaigns | Manning | Prepare an index of GPS epoch campaigns, with cross references to publications of results, and include on WG-GGI web site. |
| Geoid Mapping | Manning | Review options at GIANT meeting to progress the geoid project (need to find an agency sponsor). |
| Geodynamics | Manning | Prepare a paper on results of epoch campaigns and permanent observatories, for publication in Antarctic Science in late 1998. |
| General | Manning | Circulate notes of September 1997 GIANT meeting. |
3. Standards and Directories Program
| Project | Responsibility | Action / Decision |
| Map and Data Standards | All | Provide comments to Thomson on content of first draft (as tabled by Norway in Cambridge). |
| Mullins / Thomson | Review first draft, and determine structure of the final document (scales, data dictionary etc). Request Norway to produce second draft for Concepcion. | |
| Metadata Standards | Mullins | Arrange for NZ to further develop their
draft: 1. Determine TC211 compliance. 2. Determine AMD compliance. 3. Obtain content review by subject specialists. 4. Include satellite imagery. 5. Produce final draft for consideration at Concepcion. |
| Geodetic Standards | Manning | GIANT to consider need for Antarctic
standards: 1. Reference Systems 2. Quality Descriptions 3. Data transfer and Interface Consider TC211 and IGS standards as basis. |
| SPA Specifications |
|
No further action required, unless requested by GOSEAC. |
| Station Map Specifications | Mullins | Determine status of 'COMNAP Stations Handbook' - does COMNAP require assistance with a standard specification for station maps and plans? |
| Toponymic Guidelines | Clarke | Discuss with SCAR and COMNAP Execs mechanism for 'one name per feature' policy for all future names. |
| Clarke | Prepare and circulate outline of a paper on Antarctic place names for the Polar Record (to be jointly authored with Sievers and Cervellati(?)) | |
| Sievers | Update collection of national Antarctic place naming policies (to be verified at Concepcion). | |
| Geographic Data Directory | Mullins | Update Web Site linking existing national and international sites with relevant directory information. |
| Mullins | Prepare proposal on GGI directory for discussion at Concepcion, considering TC211, DIF, AMD and GLIS. | |
| Mullins | Update SCAR Map Catalogue based on USGS holdings. Circulate to all countries for review, then table final (Supplement or new Edition) at Concepcion. | |
| GIS Project Register | Mullins | Arrange for NZ to report on updates and site visits at Concepcion meeting (to enable review of needs). |
| Project | Responsibility | Action / Decision |
| Composite Gazetteer | Thomson / Sievers | Objectives are to: 1. Validate web site database by Concepcion. 2. Produce interim hardcopy for WG Members and SCAR Delegates at Concepcion (say 100 copies), without descriptive info or date of approval. 3. Obtain SCAR approval for publication of official Gazetteer (say end 1998). |
| Thomson | Arrange following changes to Gazetteer web
site: 1. Confirm GEBCO vs. IHO as bathymetric place naming authority - amend documentation as required. 2. Include a title of 'Draft Working Version', or similar, and a preface table indicating data sources, limitations 3. Ensure that pejorative terms such as 'variant' are deleted from all documentation - use 'features'. 4. Adopt definition of 'Date of Approval' as used by each authority (document actual definitions in preface) |
|
| Clarke | Arrange for SCAR to write to Argentina, Belgium, Chile, Norway regarding status of their contributions. | |
| Thomson | Review (with Italy at October meeting): 1. Process for validating the composite data 2. Capacity to produce the 100 copies for Concepcion 3. Database used (system, model, schema) 4. Capacity to maintain the database/site for next 5 yrs Circulate notes of the meeting to WG Exec. |
|
| Thomson | Prepare (with Italy) and circulate to Exec for comment, the title, preface pages and indicative content of the Concepcion draft hardcopy. | |
| Antarctic Digital Database | Thomson | Objective is to publish Version 2 on the Web. Issues to be considered are: 1. File sizes and downloading times 2. Use of ICAIR as distribution site 3. Registration of users (as alternative to purchasers) |
| Digital Elevation Model | Sievers | No collaborators identified for this project. Continue to monitor developments. |
| Station Maps / SPA Maps | Thomson | No further action pending COMNAP or GOSEAC requests. |
| Ground Control Point Library | Sievers | Prepare paper on scope of the SCAR project, then review fit and relationship to current NASA project. |
| Data Integration | Clarke | Arrange for detailed scoping study and data survey results to be tabled at Concepcion. |
