    45  * G7:i.albedo: new
    46  * G7:i.aster.toar: new, transforms calibrated digital number of ASTER data to top-of-atmosphere radiance, reflectance and temperature
    47  * G7:i.biomass: new
     45 * G7:i.albedo: new - Computes broad band albedo from surface reflectance.
     46 * G7:i.aster.toar: new - Transforms calibrated digital number of ASTER data to top-of-atmosphere radiance, reflectance and temperature
     47 * G7:i.biomass: new  - Computes biomass growth, precursor of crop yield calculation
    4848 * i.class: rewritten in [http://grasswiki.osgeo.org/wiki/WxIClass wxGUI]
    4949 * G7:i.cca: supports now much more raster maps for canonical analyses (multi-spectral (8) -> hyper-spectral (thousands)),  converted from Fortran style to C-style
    50  * G7:i.eb.eta: new
    51  * G7:i.eb.evapfr: new
    52  * G7:i.eb.h_sebal01: new
    53  * G7:i.eb.netrad: new
    54  * G7:i.eb.soilheatflux: new
    55  * G7:i.emissivity: new
    56  * G7:i.evapo.mh: new
    57  * G7:i.evapo.pm: new
    58  * G7:i.evapo.pt: new
    59  * G7:i.evapo.time: new
     50 * G7:i.eb.eta: new - Actual evapotranspiration for diurnal period (Bastiaanssen, 1995)
     51 * G7:i.eb.evapfr: new - Computes evaporative fraction (Bastiaanssen, 1995) and root zone soil moisture (Makin, Molden and Bastiaanssen, 2001).
     52 * G7:i.eb.h_sebal01: new - Computes sensible heat flux iteration SEBAL 01
     53 * G7:i.eb.netrad: new - Net radiation approximation (Bastiaanssen, 1995).
     54 * G7:i.eb.soilheatflux: new - Soil heat flux approximation (Bastiaanssen, 1995).
     55 * G7:i.emissivity: new - Computes emissivity from NDVI, generic method for sparse land
     56 * G7:i.evapo.mh: new - Computes evapotranspiration calculation modified or original Hargreaves formulation, 2001.
     57 * G7:i.evapo.pm: new - Computes potential evapotranspiration calculation with hourly Penman-Monteith.
     58 * G7:i.evapo.pt: new - Computes evapotranspiration calculation Prestley and Taylor formulation, 1972.
     59 * G7:i.evapo.time: new - Computes temporal integration of satellite ET actual (ETa) following the daily ET reference (ETo) from meteorological station(s).
    6060 * G7:i.fft and G7:i.ifft: In GRASS 6.x, the only operation which can be performed upon the FFT data is a binary mask; a given component can be included or excluded, but not scaled. In GRASS 7.0, the frequency coefficients are saved as raster maps, so they can be manipulated with e.g. G7:r.mapcalc. The main constraint is that both i.fft and i.ifft require the data to fit into memory. Eliminating this requirement boils down to transposing a large array efficiently.
    6161 * G7:i.latlong: new
