GeoIndexR: Computation of Spectral and Geospatial Indices from Multispectral Raster Data

Description

A unified, fast, and extensible framework for calculating spectral and geospatial indices from multispectral raster datasets (e.g., NDVI - Normalized Difference Vegetation Index, NDWI - Normalized Difference Water Index, MNDWI - Modified Normalized Difference Water Index, NDBI - Normalized Difference Built-up Index, SAVI - Soil Adjusted Vegetation Index, EVI - Enhanced Vegetation Index, GNDVI - Green Normalized Difference Vegetation Index, NDMI - Normalized Difference Moisture Index, BSI - Bare Soil Index). Designed around 'terra' 'SpatRaster' objects, it supports multi-band rasters, automatic band resolution, sensor presets (Sentinel-2, Landsat-8/9), customizable index parameters, vectorized computations, and comprehensive validation. Methods based on Rouse et al. (1973), McFeeters (1996) \Sexpr[results=rd]{tools:::Rd_expr_doi("10.1080/01431169608948714")}, Xu (2006) \Sexpr[results=rd]{tools:::Rd_expr_doi("10.1080/01431160600589179")}, Zha et al. (2003) \Sexpr[results=rd]{tools:::Rd_expr_doi("10.1016/S0034-4257(03)00087-7")}, Huete (1988) \Sexpr[results=rd]{tools:::Rd_expr_doi("10.1016/0034-4257(88)90106-X")}, Gitelson et al. (1996) \Sexpr[results=rd]{tools:::Rd_expr_doi("10.1016/S0034-4257(96)00072-7")}, Wilson and Sader (2002) \Sexpr[results=rd]{tools:::Rd_expr_doi("10.1016/S0034-4257(01)00318-2")}, and Rikimaru et al. (2002).
