Significant atmospheric correction improvements can only be achieved by accurately representing the dynamic variability of the intrinsic atmospheric optical parameters that serve as input to the radiative transfer model. The challenge is to render the existing array of ground and satellite based (input) atmospheric optical measurements coherent and standard. This is accomplished by assimilating the atmospheric optical measurements and their expected errors with a spatiotemporal atmospheric model driven by meteorologicalscale wind fields. Such models act as intelligent interpolators in space and time, and as a tool for product QA and standardization. The concept of a meteorological scale optical parameter prediction system for atmospheric corrections (NOMAD for "Networked On-line Mapping of Atmospheric Data") is presented in this communication along with examples of ongoing developmental work. The system is viewed as multi-level in that it will output atmospheric optical parameter estimates ranging from the meteorological to climatological scales and from the synoptic scale to the lower mesoscale (AVHRR scale to SPOT scale). The operational concept is that it will reside on a central server that will be accessible to any atmospheric correction system. Aside from the obvious advantage of atmospheric corrections operationalization, this concept will transfer the responsibility of quality assuring atmospheric parameters from the user to the science and technical staff maintaining the atmospheric server.

“…However, these systems are either platform specific, very difficult to develop or not very easy to be discovered and used by clients. Most of these systems are developed for specific applications, and work with specific datasets [3]. These systems tie data and processing functionality together, making them unavailable for most other systems.…”

Internet has been employed as an efficient avenue for the dissemination of a variety of geospatial information. However, the distribution of the geospatial processing capabilities over the Internet, especially those related to geospatial image processing, is still lacking. Many customized solutions based on CORBA (Component Object Request Broker Architecture) and DCOM (Distributed Component Object Model) have been developed to deliver geoprocessing functionality online but they are often designed to operate on specific datasets and they cannot interact with other online data sources easily. Geoprocessing is usually achieved through a series of steps. The inability of these solutions to support generic online data makes it impossible to chain with other systems to perform sequential processing. The inseparability of data and geoprocessing functionality of these online solutions has limited their usability.To achieve the separation between online data suppliers and geospatial processing functionality, a framework of geoprocessing web services is proposed in this research. An online image geometric rectification web service is developed as an example. This web service allows the images to be rectified and transformed into a known geographic projection (with map coordinates). The reference images or maps with known projection can be obtained from a data supplier web service. The users of the client application can identify ground control points (GCPs) from both the reference digital map/image and the local input image. The proposed image geometric rectification web service then performs the actual rectification based on these GCPs and returns to the client application the transformation parameters estimated through a least square solution. Due to the use of industry standard technologies such like XML, SOAP, WSDL, and UDDI to build geoprocessing web services, it is possible to distribute the geoprocessing capabilities in a platform and language independent manner over the Internet, with faster client application development, easier service deployment and efficient online discovery.
