Developing one map of national marine resources of Indonesia

Indonesia is the largest archipelagic country in the world, with two third of waters containing large marine resources. However, the coastal and marine resources have not been optimally utilized due to the limitation of Spatial Zoning Plan for Coastal and Small Islands (RZWP3K). In addition, there were many institutions which produce thematic maps of the coastal and marine resources (MGI) using different basemap, standard and technical specifications. Hence, same thematic maps provide different information. For these reasons, One Map Policy (OMP) is required to overcome the problems. The objective of this research was to develop datasets of one map of the coastal and marine resources needed for developing RZWP3K by using thematic layer maps produced by their respected Ministries/Agencies as the custodianships. The current custodianships of thematic maps in Indonesia is defined based on the Head of Geospatial Information Agency Decision Number 54 Year 2015. The method used the OMP approach was based on one reference, one standard, one database, and one geoportal. The research resulted the dataset of MGI integrated to the national basemap in a geodatabase format. From this research, it was concluded that the thematic maps of the coastal and marine resources which were produced in many institutions can be integrated to a national basemap and standard specification. The integrated thematic maps are then useful for developing the RZWP3K.
