MtkCreateGeoGrid()

MTKt_status MtkCreateGeoGrid	(	double	ulc_lat_dd,
		double	ulc_lon_dd,
		double	lrc_lat_dd,
		double	lrc_lon_dd,
		double	lat_cellsize_dd,
		double	lon_cellsize_dd,
		MTKt_DataBuffer *	latbuf,
		MTKt_DataBuffer *	lonbuf
	)

Creates a regularly spaced geographic 2-D grid consisting of a latitude buffer and a longitude buffer in decimal degrees, given upper left and lower right latitude/longitude coordinates and latitude/longitude cell size.

Returns

MTK_SUCCESS if successful.

Example:

In this example, we create a regularly spaced geographic 2-D grid of lat/lon spanning the upper left latitude 40.0, longitude -120.0 and lower right latitude 30.0, longitude -110.0 with a cell size of 0.25 degrees in both lat/lon.

status = MtkCreateGeoGrid(40.0, -120.0, 30.0, -110.0, 0.25, 0.25, &latbuf, &lonbuf);

Note

The caller is responsible for using MtkDataBufferFree() to free the memory used by latbuf and lonbuf

Parameters

[in]	ulc_lat_dd	Upper left corner latitude
[in]	ulc_lon_dd	Upper left corner longitude
[in]	lrc_lat_dd	Lower right corner latitude
[in]	lrc_lon_dd	Lower right corner longitude
[in]	lat_cellsize_dd	Latitude cell size in decimal degrees
[in]	lon_cellsize_dd	Longitude cell size in decimal degrees
[out]	latbuf	Latitude data buffer
[out]	lonbuf	Longitue data buffer
