A comprehensive toolkit for geospatiotemporal analysis
featuring 60+ vegetation indices, advanced raster visualization,
universal spatial mapping, water quality analysis, CDL crop analysis,
spatial interpolation, temporal analysis, and terrain analysis.
Designed for agricultural research, environmental monitoring, remote
sensing applications, and publication-quality mapping with support for
any geographic region and robust error handling. Methods include
vegetation indices calculations (Rouse et al. 1974), NDVI and enhanced
vegetation indices (Huete et al. 1997)
