make_3d_grid
(sitecoords, proj, maxrange, maxalt, horiz_res, vert_res, minalt=0.0)¶ Generate Cartesian coordinates for a regular 3-D grid based on radar specs.
- Parameters
sitecoords (tuple) – Radar location coordinates in lon, lat
proj (object) – GDAL OSR Spatial Reference Object describing projection
maxrange (float) – maximum radar range (same unit as SRS defined by
proj
, typically meters)maxalt (float) – maximum altitude to which the 3-d grid should extent (meters)
horiz_res (float) – horizontal resolution of the 3-d grid (same unit as SRS defined by
proj
, typically meters)vert_res (float) – vertical resolution of the 3-d grid (meters)
- Keyword Arguments
minalt (float) – minimum altitude to which the 3-d grid should extent (meters)
- Returns
output (
numpy.ndarray
, tuple) – float array of shape (num grid points, 3), a tuple of 3 representing the grid shape
