The correlogram is estimated as a function of range.
So, provide the maximum range that we should consider (in pixels). The distance is computed in pixels of a lat-lon grid (not in kms), so provide the latitude and longitude resolution of that grid here.

| const Sample& w2img::Correlogram::operator[] | ( | size_t | dist | ) | const [inline, inherited] |
get the correlation between two samples separated by dist pixels in an euclidean framework.
dist has to be less than getMaxDistanceInPixels()
| size_t w2img::Correlogram::size | ( | ) | const [inline, inherited] |
Distance to which we have samples available.
| void w2img::DataTableCorrelogram::update | ( | const code::DataTable & | table | ) |
update based on the rows in this table.
The distances between the rows in this data table are cached, so we don't need to recompute.
| bool w2img::Correlogram::write | ( | const std::string & | filename | ) | const [inherited] |
Write the correlogram values in a format fit to be easily plotted.
