SW for creation of arrows and ellipses shapefiles for GIS
SW for creation of arrows and ellipses shapefiles for visualization of vectors error ellipses etc. Input is structured text file. Output is shapefile (open specification from ESRI). Shapefile is widely used in GIS SW.
...Project goal is to generate a toolkit for 2D and 3D bathymetric mesh generation via an anisotropic adaptive mesh method. Emphasis is on approximation with clearly defined error goals so that the final model is quantitatively useful.
Simulates data from a gaussian/beta/piecewise-linear species response function on an environmental gradient, with different sampling (error) distributions. See "Cline (biology)" on wikipedia.org.
