Function Documentation

void reproject (  grid_type *  src_grid, grid_type *  target_grid, distance_type  distance, time_type  max_dtime )

reprojects src_grid over target_grid The current implementation uses a "nearest neighbour" policy, an optional argument might be added to choose the reprojection policy (with this one by default) Source and target grids must meet some requirements : their grid_type::lat, grid_type::lon and grid_type::tim fields must be filled grid_type::lat must contain values in degrees between MIN_LAT and MAX_LAT grid_type::lon must contain values in degrees between MIN_LON and MAX_LON grid_type::tim must contain values in time_type (TAI93, Temps Atomique International 1993), e.g. a number of seconds since the 1st Jan 1993, 0h00 UTC Parameters: src_grid  the grid whose content is to reproject target_grid  the grid over which reprojection is to be done distance  the maximal search distance for the nearest neighbour max_dtime  the maximal time difference for the nearest neighbour reproject updates the following fields of target_grid : grid_type::data grid_type::distance_from_ref grid_type::time_from_ref grid_type::src_irows (currently not used) grid_type::src_icols (currently not used)
