The national spatial data metadata (MDSN) database was established in 2002 by BAKOSURT ANAL as national agency for surveys and mapping. Ideally MDSN consists of metadata from all spatial data producers in Indonesia and gives information about metadata to users via internet. The problems are (1) all spatial data users agree that spatial metadata is important. However, not all spatial data providers accompany their spatial data with appropriate metadata, (2) the constructed standard of national metadata database consists of many items and it could be complicated for many users to understand, and (3) spatial data may come from various sources with different reference system. It requires specific handling method for each spatial metadata database since not all of the content of spatial metadata is applicable for each data source.
The objectives of this research are (1) to develop strategic plan to encourage all spatial data providers to participate in national spatial metadata system (2) to develop guideline on constructing a spatial metadata database as a part of national spatial metadata system (3) to develop spatial metadata database of Mahakam Delta of East Kalimantan that can be accessed from national spatial metadata system.
The method used in this research consisted of literature study and fieldwork. In the fieldwork, questionnaire and content of metadata database from data providers were used to collect data that were then used to identify the problems. The identified problems were analyzed using SWOT analysis method resulting in a proposed strategy for the development of national metadata in the future. Then the research also proposed guidelines, and developed spatial metadata database related to national metadata.
According to survey result, major problems in implementing metadata are: (a) vision, perception, motivation, and understanding were not uniform among data providers also between operator level until decision maker and (b) no strong coordination / cooperation among data producers. Several strategic plans have already been developed, and the result can be proposed to develop the national metadata program in the future. Several strategic proposed plans were (I) the need of socialization among data providers about national metadata to avoid spatial data providers not interested to joint the program (2) the need of law/regulation about national metadata to avoid miss coordination function of the metadata center. The guidelines for filling metadata database have also been developed. This research focused on two types of spatial data ( 1) topographic map representing the map data and (2) landsat image representing satellite image data. The metadata database related with national metadata was tested with a case study of spatial data of Mahakam Delta, and ICOMar as data provider.
