Calculates multi-scale geomorphometric terrain attributes from regularly gridded DEM/bathymetry rasters.
CRAN says tarball of package should be below 5MB to streamline checks. Maybe reduce dpi of figures in vignettes.
"An additional benefit of the quadratic surface is the derivation of the R2 goodness of fit statistic, which allows an assessment of both the reliability of the results and the...
Explore adding support for more functions to be used in unprojected coordinate systems. raster::terrain [(terrain.R,](https://github.com/rspatial/raster/blob/master/R/terrain.R) [terrain.cpp)](https://github.com/rspatial/raster/blob/master/src/terrain.cpp) uses haversine distance and [ArcPro Surface Parameters uses a 3D Earth Centered, Earth Fixed...
Add option to fit a 3rd order instead of second order polynomial in Qfit (Florinsky, 2016). Florinsky, I.V., 2016. Digital terrain analysis in soil science and geology, 2nd ed. Elsevier/Academic...
Have option to have weights for each cell (e.g. inverse distance weighted). From Wood, 1996: "In common with all inverse distance functions, an (arbitrary) decision has to be made about...
To remove correlation among successively larger spatial scales that include data from all previous scales, add option for the quadratic to be fit only using only the outer edge of...
Determine and implement a list of test cases to make sure functions are working as intended after each update

Packages in Suggests should be used conditionally: see 'Writing R Extensions'. This needs to be corrected even if the missing package(s) become available. It can be tested by checking with...
