This routine has been replaced with the OpenRaster method to ENVI.
Use this procedure to open a data file. ENVI Classic supports several standard file types, including formats for selected sensors, military formats, DEM formats, image processing software formats, and generic image formats.

Arguments
Fname
Specify the filename to open.
Keywords
Set one of the following optional keywords to specify the type of file being opened.
ACRES (optional)
ACRES CCRS Landsat and SPOT data
ADRG (optional)
Defense Mapping Agency ARC Digitized Raster Graphics (ADRG) format
ALOS (optional)
Advanced Land Observing Satellite. Use this keyword to read data from the Panchromatic Remote sensing Instrument for Stereo Mapping (PRISM) sensor, Advanced Visible Near-Infrared Radiometer (AVNIR-2) sensor, or Phased Array type L-band Synthetic Aperture Radar (PALSAR) sensor on the ALOS satellite.
ASTER (optional)
Earth Observing System (EOS) Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) data
ATSR (optional)
Gridded brightness temperature (GBT), gridded browse (GBROWSE), and gridded SST (GSST) data from ATSR-1 and ATSR-2
AVHRR (optional)
- Level 1B data from the NOAA-K through -M satellites (KLMN)
- Standard-family HRPT Archive Request Product (SHARP) format
- Quorum format
Note: To open an AVHRR file in the ESA_SHARP format, set the keyword ESA_SHARP instead of AVHRR.
BMP (optional)
Bitmap
CADRG (optional)
Defense Mapping Agency Compressed ARC Digitized Raster Graphics (CADRG) format
CIB (optional)
Defense Mapping Agency Controlled Image Base (CIB) format
CORRECTED_SRTM_OUT_NAME (optional)
If you are reading SRTM data (and you set the SRTM keyword), you can choose to automatically correct bad data points. Set CORRECTED_SRTM_OUT_NAME to a filename to store the corrected data points. If you do not want to automatically correct bad data points in SRTM data, do not use CORRECTED_SRTM_OUT_NAME.
COSMOSKYMED (optional)
Set this keyword to read COSMO-SkyMed data in HDF5 format. ENVI Classic supports the following COSMO-SkyMed products:
- Level-1A Single look, complex, slant range (SCS)
- Level-1B Detected Ground Multilook (DGM)
- Level-1C Geocoded Ellipsoid Corrected (GEC)
DIMAP (optional)
SPOT-5 Digital Image Map
DMSP (optional)
NOAA Defense Meteorological Satellite Program (DMSP) Operational Linescan System (OLS) format
DOQ (optional)
USGS Digital Orthophoto Quadrangle data
DRG (optional)
USGS Digital Raster Graphics data
ECW (optional)
Enhanced Compressed Wavelet
ENVI (optional)
ENVI Classic standard file formats
ENVISAT (optional)
AATSR, ASAR, or MERIS data
EOSAT_IRS (optional)
Indian Remote Sensing (IRS) data in Earth Observation Satellite Company (EOSAT) Fast format
EOSAT_TM (optional)
Landsat TM data in EOSAT Fast format
ERMAPPER (optional)
ER Mapper
EROS_1A (optional)
Earth Resources Observation System 1A data
ERS (optional)
European Remote Sensing Satellite-1 or -2
ESA_SHARP (optional)
European Space Agency SHARP data
ESA_TM (optional)
European Space Agency CEOS Landsat TM data
FORMOSAT2 (optional)
FORMOSAT-2 DIMAP (.dim) data
HDF_SD (optional)
HDF Scientific Data
HDFSD_DATASET (optional)
This keyword prevents the HDF Dataset Selection dialog from appearing if you set the keyword HDF_SD. The keyword HDFSD_DATASET allows you to select an HDF dataset without any user interaction. Set this keyword to the index of the specific HDF dataset you want to open within an HDF file. If this dataset contains three dimensions, you must specify a HDFSD_INTERLEAVE value. If the dataset has only two dimensions, then interleave is ignored.
HDFSD_INTERLEAVE (optional)
Set this keyword to one of the following values if the dataset index you specified in HDFSD_DATASET has three dimensions.
- 0: BSQ (default)
- 1: BIL
- 2: BIP
IMAGINE (optional)
ERDAS IMAGINE 8.x (or later) file. This keyword opens both .img and .ige IMAGINE files.
INVISIBLE (optional)
Set this keyword to prevent the file from automatically displaying in the ENVI Classic interface. This keyword only applies when using ENVI_OPEN_DATA_FILE in ENVI Classic programming. A file opened with the INVISIBLE keyword set will not appear in the Available Bands List and will not automatically display.
IRS_SUPER (optional)
IRS Super Structured data
JERS (optional)
Japanese Earth Resources Satellite
JP2 (optional)
JPEG2000
JPEG (optional)
JPEG
KOMPSAT2 (optional)
