atpol100k |
atpol100k creates ATPOL grid 100km x 100km and returns it as sf object |
atpol10k |
atpol10k returns ATPOL grid 10x10 km and returns it as sf object |
atpol1k |
atpol1k creates ATPOL grid 1km x 1km and returns it as sf object |
atpol_div |
atpol_div creates ATPOL grid divided by 2, 4 or 5 (based on divider parameter) and returns it as sf object. Useful for grids like 5 x 5 km (divider = 2), 250 x 250 m (divider = 4) or 20 x 20 m (divider = 5). For details see Verey and Komsta (2018) |
boundaryPL |
boundaryPL reads the file data/pl_boundary.Rds with simplified boundary geometry. |
check_atpol_square |
Reverse engineering of published ATPOL grids |
grid_to_latlon |
grid_to_latlon converts the ATPOL grid to latitude and longitude. With 'xoffset = 0' and 'yoffset = 0' parameters it returns coordinates of the upper left corner of the grid. |
latlon_to_grid |
latlon_to_grid(lat, lon, length) converts geographical coordinates to ATPOL grid of given length |
plotPoitsOnAtpol |
plotPoitsOnAtpol() plots the observations on ATPOL 10km x 10km grid |
