Development of Ogc Framework for Estimating Air Temperature from Modis Lst and Sensor Network

While the satellite data and meteorological measurement are more easily available, there is a lack of comprehensive framework that provides an estimated air temperature map with ease of use to the end-users. This study focus on the developing of a comprehensive web based framework for estimating air temperature map from MODIS LST evaluated relationship with in-situ data collected over a distributed sensor network of ground sites. The development is based on various open standards of OGC (Open Geospatial Consortium) Web Service specifications such as Web Processing Service (WPS), Sensor Observation Service (SOS), Web Mapping Service (WMS) and Web Coverage Service (WCS). The availability of high temporal measured air temperature by sensor network provides as a superior ground based data source for estimating air temperature from satellite observation. The MODIS LST dataset as a data source from WMS server was evaluated relationship with near surface air temperature of Live E! Project sensor network weather station from SOS server to calculate air temperature map with on-demand processing capability of developed WPS server requesting satellite data source from WCS server. The developed OGC specification compliance system, that supports interoperability, scalability and robust platform, shows its powerful potential for standard data sharing and on-demand processing interfaces on satellite image and sensor observation data.
