3. 1. About PCGIAP Regional body for National Spatial Data Infrastructure (NSDI) integration Operates under the UN Regional Cartographic Conference for Asia and the Pacific Established in 1995 Executive board and working groups/taskforce President: Mr. Peter Holland (Australia) Vice president: Mr. Komaki Kazuo (Japan) Secretariat: Mr. Li Weisen (China)

4. Members Consists of 55 members in Asia and the Pacific Represented by Directorate of national survey and mapping organizations

5. Aim of PCGIAP To maximize the economic, social and environmental benefits of geographic information by providing a forum for Asia and the Pacific to:  Cooperate in the development of a Regional Spatial Data Infrastructure (RSDI), “APSDI”  Contribute to the development of the Global Spatial Data Infrastructure (GSDI)

6. Display Detailed Metadata Search for Suppliers, Data and Services 2. Why We Need Metadata 6 8th PCGIAP meeting decided implement the prototype of APSDI clearinghouse. APSDI Clearinghouse is an environment that can facilitate access to geo-spatial data, products and services Discover Resource Evaluate Resource Access Resource

7. 7 APSDI Clearinghouse – Architecture APSDI Clearinghouse consists of nodes, each clearinghouse node is composed of metadata of geo- spatial data and a software system for serving metadata Datasets Metadata Web Server Catalog Server Clearinghouse Node Clearinghouse Gateway Metadata is one of the key components

9. Review During 7 th PCGIAP Meeting, 2001-4,Tsukuba,Japana  A task force for APSDI data node was formed  Task: promoting the planning and implementation of APSDI spatial data clearinghouse.  Started a pilot project Before 8 th PCGIAP Meeting, 2002-4,Brunei Darussalam  Workshop on APSDI Clearinghouse (Hainan Islands, China, Nov. 2001);  PCGIAP Metadata profile drafted;  Guidelines for APSDI Clearinghouse Node Development drafted.

10. Review Before 9 th PCGIAP meeting, 2003-7,Okinawa, Japan  PCGIAP Metadata profile And a metadata entry tool named Mediator complying to this profile is developed and free available.  Guidelines for APSDI Clearinghouse Node Development finished and a reference prototype Implementation of APSDI Clearinghouse provided at http://nfgis.nsdi.gov.cn/apsdi

11. Review Before 11 th PCGIAP Meeting, 2005-5,Bali, Indonesia  Joint Workshop of WG1 and WG2,7- 9 September 2004, Chengdu, China  Closed the pilot project and reinstituted the taskforce  ESRI GIS Portal Toolkit Workshop for PCGIAP, 6-8 April, 2005, Hong Kong, China 13 participants from 6 members (China, Indonesia, Japan, Korea, Nepal, Malaysia) attended 12 th PCGIAP & 17 th UNRCCAP, Tailand, 2006 Recommends PCGIAP encourage close collaboration between PCGIAP Working Group 2 with ISO/TC211 in the development of an ISO Metadata standard profile for Asia Pacific.

15. PCGIAP Metadata profile They are enough to answer ”what, why when who, where and how” questions about geospatial data. What - title and description of the data set. Why - abstract detailing reasons for the data collection and its uses. When - when the dataset was created and the update cycles if any. Who - originator, data supplier, and possibly intended audience. Where - the geographical extent based on latitude / longitude, co-ordinates, geographical names or administrative areas. How - how it was built and how to access the data.

16. Metadata Edit Tool Features: Use treeview to represent the relationship between elements of different level in the hiberarchy structure. Pop-up menu can be created dynamically according to the adopted schema You can customize the interface, template, and even add new XML Schema to enable this software to create other XML file according to the specified XML Schema. A lot of short cuts, pop-up menu enable you edit your document freely. Used to capture metadata complying to the profile
