>
> When opening a Sentinel 1 GeoTIFF image, the call to
> {{DataStore.getMetadata()}} cause the JVM to attempt to allocate about one
> gigabyte of memory. This is not caused by the image size, but rather by a
> mathematical error. In the {{LocalizationGridBuilder}} class, private method
> {{infer}} computes the greatest common divisor of _X_ and _Y_ translations
> from the grid origin. Sentinel 1 image have control points spaced by 1320
> pixels on the _X_ axis, except the very last point which is only 1302 pixels
> after the previous one. This cause {{LocalizationGridBuilder}} to find a much
> smaller common divisor than expected (6 instead of 1320), which cause it to
> attempt to create a localization grid much larger than it should be.
