Previous Projects
COMET - The COast-to-Mountain Environmental Transect Project. http://comet.ucdavis.edu/. Developed Web applications for real-time visualization of sensor streams based on open software components and standards. See live sensor data streams here.
GeoStreams - Adaptive Query Processing Architecture for Streaming Geospatial Image Data. http://www.db.cs.ucdavis.edu/geostreams. Designed and implemented a real-time visualization tool for streaming satellite images based on a formal image stream model. See live data from the GOES West satellite here.
StarSpan - A tool for fast data extraction from remotely-sensed imagery. http://starspan.projects.atlas.ca.gov/. Implemented quadtree based algorithms for fast vector-raster intersection and extraction of pixels.
SAMS - Spectral Analysis and Management System. http://code.google.com/p/cstars-sams/. This application allows the user to manage field spectra databases and perform some typical pre-processing analyses. Features include: import/export options in various formats, signature groupings, metadata management, common operations on single or multiple signatures, richer set of plotting capabilities, and a simple data structure for easy integration with other applications.
RTM - Radiative Transfer Model Repository. http://rtm.projects.atlas.ca.gov/. This project seeks to provide a repository of programs and programming libraries implementing Radiative Transfer Models for Remote Sensing research and applications. I myself have contributed to the repository by re-implementing a number of well-known models. Factors like software modularization and flexibility have been the major motivations for this reimplementation. In particular, these features have made easier to develop both linked leaf-canopy models and efficient numerical inversions.
GOES - Reference Evapotranspiration calculation for California. http://goes.casil.ucdavis.edu/. Developed programs for interpolation of ground measured variables (air temperature, vapor pressure, etc.), solar position calculations, and automated download of data from CIMIS stations. Some of this programs are GRASS GIS commands.
some other misc tools developed at CSTARS
red_edge_gauss. A program to compute the red-edge of an image by using an inverted-Gaussian based method.
spectral_index_calculation. A program to compute user-defined spectral indices on remote sensing images.
