"I've attached fixes to DataSet that should fix the problems that Maya was seeing yesterday. The issue was that the new interpolation code I submitted didn't use the SourceData's georef, it was assuming that the GDALDataSet had a proper geo-ref. I've made the getInterpolatedValue method a member of SourceData and now it uses the georef the SourceData's georef.
I also forward declared the GDALRasterBand class in the DataSet header."
