Abstract

With increasing volumes of hyper-spectral, multi-source data, there is a high demand for automation and simplification of the process for advanced remote sensing classification research. We present a novel geospatial modeler tool. With flexible modeling and data analysis function, this tool provides an easy environment for scientist and educators for remote sensing community.

The tool is designed toward a generic framework for external packages integration. Three major components are graphic modeler, algorithm toolbox, and result viewer. Developed in a modular fashion, it incorporates algorithms written with languages which are widely used in remote sensing application, including Python, R, Matlab, and C (GDAL/OGR executables). This tool has features such as data loading and transformation, preprocessing, modeling, validation and visualization. Geospatial data processing routines are already available, and the ease of model building and program development makes it straightforward to implement new algorithms and to assess the results. Collecting data visualization routines into the package will make them readily available for evaluation for particular applications.

As part effort of the GAABS project, we demonstrate the abilities of HUBzero to host the tool. The tool is deployed and configured at GeoHub server. A synergy effect in the simple flexible tool framework and a powerful fabric of RS/GIS libraries and applications in HUBzero can be observed. We extend the HUBzero platform by integration with IData service. Input and output data, and algorithms are readily shared across network, which allow researches in cooperative environment.
