A New Method to Publish Spatial Sectoral Data and Spatial Planning in Local Government to Support One Map Policy (Case Study : East Java)

Spatial data could be sectoral data or city spatial planning data. Province government manage sectoral data, whereas local government manages city spatial planning. To management spatial data, local government can't access sectoral data in the provincial government. It has happened because there is no procedure to integrate their data. Each region/city also has their different map version so, that allows overlapping. This is because each local government hasn't reference in solving spatial, land, or development problems. Therefore a One Map Policy was formed, is becoming an important point that should be considered to be realized. This paper presents a new automatic WebGIS framework to integrate sectoral data and city spatial planning for support One Map Policy. This system using REST API Geoserver technology. This technology is carried out automatically with a web browser. In this case, Every local government can manage and access this system. In carrying out the process, each data must be in accordance with the Standard Operating Procedure (SOP) of the application system. Each local government will upload data using a web browser and the system will work automatically. After the data is successfully stored, the system also automatically processes the Geoserver until a layer is formed. The formed layer is ready to be displayed to WebGIS using Web Map Service. With REST API technology, it will help to manage the creation of a spatial and information system more efficient. The experiment result shows that this system can integrate the data between local government and provincial government. And it can use as a reference in the process of managing spatial data and information in the local government of East Java Province to support One Map Policy.
