Understanding the importance of public access to spatial data, several activities related to the development of Spatial Data Infrastructure (SDI) being carried out through national initiative under the leadership of National Coordinating Agency for Surveys and Mapping (BAKOSURTANAL), an Indonesian government body
As a result of long survey and mapping activities, Indonesia has enormous collection of spatial data consisting of geodetic control points, topographic database, bathymetric database, and thematic database covering most of the national territory. Such data is collected and managed by many government agencies at all levels : national, provincial, districts and municipal, and also stored at different local standards. Beside develop databases, some agencies also build its metadata which is also developed in local metadata standards
Understanding the importance of public access to this data, several activities related to the development of Spatial Data Infrastructure (SDI) was carried out through national initiative under the leadership of National Coordinating Agency for Surveys and Mapping (BAKOSURTANAL), an Indonesia government body.
As a result of this initiative effort, every year all spatial data stakeholder meet in National SDI Coordination Meeting. In this meeting several important issues relating to the ISDI development is discussed. In addition to that, a prototype of Indonesian Clearinghouse has been installed in BAKOSURTANAL website.
For this purpose the FGDC metadata standards is adopted as a national metadata standard and a national metadata and data directory server applying Z39.50 protocol has been built. The application of Z39.50 protocol to metadata server ensures the access opened globally.
Several data standards and a draft of data management mechanism are also available at present. These are created for the agencies in order to develop and maintain their spatial database in such a way that the databases are of good quality, well maintained and nationally integrated. For this purpose a national technical committee of spatial data is established.
In order to authorize the implementation of ISDI development, efforts to pass a law and a presidential decree is being carried out. It is expected that with the present of the law and the decree the national support to the development of ISDI increased and the realisation of the ISDI can be fastened.
Although significant results from the national survey and mapping activities has been obtained since the first institutional meeting years ago, users still find it difficult to obtain and use of spatial data. Here are problems encountered to this difficulties.
In relation to obtaining spatial data, this can be explain follows. Firstly, Most spatial data produced by the agencies is developed for their own used so that there is no awareness to disseminating this to others. Secondly, data is not well managed which causes the data distribution time to user becomes lengthy and uncertain. Finding data is not also easier than obtaining it since there is not well data directory available, let alone the data directory covering the country.
Finally, for any agency that has been prepared to distribute data feels inconvenience since there is no regulation or procedure to protect data from any misuses.
Dealing with using spatial data, data produced by the agencies are created in standards fitted only to their own needs. This disparate datasets create integration problems to those who will use several datasets combined. Even if there is a dataset comply to any standard, the users are not satisfy because standard used is not appropriate to user needs.
