Function Documentation

◆ MtkChangeMapResolution()

MTKt_status MtkChangeMapResolution	(	const MTKt_MapInfo *	Map_info_in,
		int	New_resolution,
		MTKt_MapInfo *	Map_info_out
	)

Change resolution of an MTKt_MapInfo structure.

New resolution must be an integer multiple of the base MISR resolution, defined by MAXRESOLUTION.

The edges of the output map will be anchored at the same locations as the input map. Therefore, the size of input map must evenly divisible by the new resolution.

Returns: MTK_SUCCESS if successful.

Example:

status = MtkChangeMapResolution()

Note

Parameters

[in]	Map_info_in	Input map information
[in]	New_resolution	New resolution.
[out]	Map_info_out	Output map information.

Definition at line 43 of file MtkChangeMapResolution.c.

◆ MtkCreateLatLon()

MTKt_status MtkCreateLatLon	(	MTKt_MapInfo	mapinfo,
		MTKt_DataBuffer *	latbuf,
		MTKt_DataBuffer *	lonbuf
	)

Creates a 2-D latitude buffer and a 2-D longitude buffer in decimal degrees corresponding to the data plane described by the mapinfo argument given a mapinfo structure.

Returns: MTK_SUCCESS if successful.

Example:: In this example, we define a region centered at lat 35.0, lon -115.0 with a lat extent of 110.0km and lon extent 110.0km. We then read the Regional Best Estimate Spectral Optical Depth and create the corresponding latutide and longitude buffers for this dataplane described by mapinfo. This routine computes the latitude and longitude for every pixel in the dataplane for which there is MISR data. It does not preclude the use of the MapQuery routines MtkLSToLatLon or MtkLatLonToLS that compute latitude and longitude. In fact this routine makes use of those routines.

MTKt_Region region = MTKT_REGION_INIT;
MTKt_DataBuffer databuf = MTKT_DATABUFFER_INIT;
MTKt_DataBuffer latbuf = MTKT_DATABUFFER_INIT;
MTKt_DataBuffer lonbuf = MTKT_DATABUFFER_INIT;
MTKt_MapInfo mapinfo = MTKT_MAPINFO_INIT;
status = MtkSetRegionByLatLonExtent(35.0, -115.0, 110.0, 110.0, "km", &region);
status = MtkReadData("MISR_AM1_AS_AEROSOL_P037_O029058_F09_0017.hdf", "RegParamsAer", "RegBestEstimateSpectralOptDepth", 
                     region, &databuf, &mapinfo);
status = MtkCreateLatLon(mapinfo, &latbuf, &lonbuf);

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

Parameters

[in]	mapinfo	Mapinfo
[out]	latbuf	Latitude data buffer
[out]	lonbuf	Longitue data buffer

Definition at line 48 of file MtkCreateLatLon.c.

◆ MtkGCTPProjInfoRead()

MTKt_status MtkGCTPProjInfoRead	(	const char *	Filename,
		MTKt_GCTPProjInfo *	Proj_info
	)

Initialize a MTKt_GCTPProjInfo structure using data from an external file.

The external file must be simple text format with parameter_name = value pairs.

Parameter names recognized by this routine are as follows: proj_code is the GCTP projection code. utm_zone is the UTM zone number for UTM projections only. sphere_code is GCTP spheroid code. proj_param(n) is the nth GCTP projection parameter. (1 <= n <= 15)
