Getting value through the GDAL RasterIO function.
Get Values directly from the GDAL Raster Band. (Slower for seldom values) get method using GDAL access function throught file buffering RasterIO method this is slow comparing to accessing the value directly from the buffered data (values data member) value should be already allocated

HOMOGENEOUS_TYPE jafar::lgl::GDRasterBand< T >::homogType [protected] |
Type of homogeneity test that will be done in the isHomogeneous method.

T jafar::lgl::GDRasterBand< T >::sigmaFactor [protected] |
Factor for admissible values in |mean - this_factor * sigma|.
From 0.0 to 3.0 are good values. Less than 0.0 will generate an always-false result (no homogeneity) while values more 3.0 will generate full homogeneity and create partitions with barely identical terrain states. Default is 1.5
Definition at line 306 of file RasterBand.hpp.
T* jafar::lgl::GDRasterBand< T >::values [protected] |
One dimension Raster Data.
2D Raster data is held in this one dimension array by transferring the data line by line (GDALRasterIO)
Because gdal use file IN/OUTPUT buffer and does not really stock all information in the memory, so copy the data to this variables for speeding up the reading and writing speed
