I want to import a large amount of ENVI rasters to an Oracle database using ArcCatalog via a ArcSDE-server. I have downloaded the DLL (ENVI Reader for ArcGIS 1.1 (Microsoft Windows NT 4.0, 2000, XP)) and installed it. This made ArcCatalog recognize the .dat-file and I can import it to the database. The problem is that I can not build statistics on the dataset and if I try to preview the dataset it is all white. Something has gone wrong here and I don´t know what to do. Can anyone please give me an advice? Thanks in advance /Nicklas
