ABSTRACT

Current web-based GIS (geographic information system) requires a more effective way of managing and distributing large time-series dataset. This paper describes a method for improving the interoperability and extensibility of web GIS services by implementing an Open API (application programming interface) for time- series raster database on the REST (Representation State Transfer) basis. We first implemented spatio-temporal operations for time-series raster dataset by creating temporal objects and temporal functions within a DBMS (database management system) which can be combined with the existing spatial objects and spatial functions of the DBMS. We employed the REST communication for a lighter request-response structure between client and server, and defined URI (unified resource identifier) interfaces for building spatio-temporal query statements. Our Open API can be consumed by any client in the identical ways irrespective of their development environments so that all computer languages supporting HTTP (Hypertext Transfer Protocol) are compatible with the Open API. For the feasibility tests of our Open API, we carried out spatio-temporal queries and the 3-D visualization of time-series raster dataset using Google Earth Web Plugin and WebGL (Web Graphics Library).
