Bborie Park 56791ce3b5 Fixed the problem where having configure detect that GDAL has the GDALFPolygonize function does not cause the code to use GDALFPolygonize. This is due to the macro GDALFPOLYGONIZE not being set anywhere. So, it is now being set in raster_config.h.in and included in rt_core/rt_api.h. Had to update testapi.c as the geometries generated differ depending on whether or not GDALFPolygonize is used.

Bborie Park 65caa54e1f Refactored functions returning sets to use Datums instead of C strings, which were causing rounding issues particularly for ST_Metadata. This refactoring affected RASTER_metadata, RASTER_bandmetadata, RASTER_summarystats, RASTER_histogram, RASTER_quantile, RASTER_valuecount and RASTER_gdaldrivers. 
Also refactored the ST_Raster2World* and ST_World2Raster* functions to get the raster's metadata in one call using ST_Metadata rather than individual calls for the georeference components

Bborie Park 48ff0b2940 Modified ST_Transform to permit specification of projected raster's scale. This is due to the scale change that occurs when a raster is being reprojected.

 2011-06-23 20:46:32 +00:00
Bborie Park 6ebb8e7534 Addition of rt_raster_gdal_warp function in rt_api.c. This was written based upon GDAL's gdalwarp utility to provide a flexible means to reproject, change the scale of, adjust the skew (deskew) of and shift the origin of a raster. RASTER_transform in rt_pg.c has been adjusted to make use of rt_raster_gdal_warp instead of rt_raster_transform. Regression te 
sts confirm that resulting rasters from rt_raster_gdal_warp are identical to that of rt_raster_transform.

The abilities to change a raster's scale, skew and origin have yet to be tested and have no user-accessible SQL functions as of this revision.  This will occur in future revisions.

The function rt_raster_transform will be removed in a future revision.

 2011-06-13 21:47:27 +00:00
Bborie Park b2ca472ea1 Added function parameter "header_only" to rt_raster_deserialize. This instructs the function to only extract the raster header. 
All functions calls to rt_raster_deserialize in rt_pg.c and testwkb.c have been modified to account for the "header_only" parameter.  In addition, functions that can use PG_DETOAST_DATUM_SLICE have been modified to use it.

Associated tickets are #867 and #985.

Bborie Park 19c5577f52 Removed the ST_SummaryStats wrappers: ST_Sum, ST_Mean, ST_Stddev, ST_MinMax. Only ST_Count is preserved as it has a shortcut for when "exclude_nodata_value" is FALSE. 
Refactored regression test for rt_transform due to removal of some ST_SummaryStats wrappers and make the tests no longer about being exact to specific values but more about being in the appropriate contexts.

Associated ticket is #1005 and to some degree, #985.

Bborie Park 1bb6dcb742 Rewrote ST_BandMetaData to use a C function instead of sequential calls for the metadata of a raster's band in plpgsql. Also added regression tests for ST_MetaData and ST_BandMetaData due to C functions.

Bborie Park 7e143b23c8 Rewrote how the standard/sample deviation is computed in ST_SummaryStats for coverage tables. It now extends the existing use of a single-pass standard deviation calculation to be able to do the calculation for a coverage table.

Bborie Park 0d83cc1894 fixed ST_SummaryStats for coverage tables where the sum of all tiles was not being computed. 
Associated ticket #1005

Also added shortcuts to ST_Count for when parameter "exclude_nodata_value" is FALSE, just compute the count based upon the raster's dimensions.  Performance difference between the normal route and the shortcut is negligible for small rasters but noticable when run on large rasters and coverage tables

Bborie Park 60c2a10862 Added support for coverage tables to ST_Histogram. This entailed adding the ability to explicitly specify the min and max values in the underlying C function rt_band_get_histogram. The min and max parameters should ONLY be used by the established coverage table handling ST_Histogram functions as the returned percent element of the histogram type is changed from returning the percentage to returning the sum of counts for that histogram. 
Associated ticket is #934.

Bborie Park 4752433c0d Add ST_Transform function that achieves the primary purpose of reprojecting a raster to a new projection system. This makes use of the GDAL Warp API function GDALAutoCreateWarpedVRT(). In the future, the underlying C function is expected to be refactored to support skewing and pixel scaling at the same time the raster is reprojected. 
Really minor changes to rt_pg/rt_pg.c adding initilization values to variables for eliminating compile warnings in Windows (thanks Pierre).

Fixed variable "status" in rt_raster_from_gdal_dataset() of rt_core/rt_api.c

Bborie Park 621954071c - added additional function parameters "bandNums" and "count" to rt_raster_to_gdal_mem so that the GDAL dataset created only contains those bands specified
