The ENVI file reader has not been updated in quite some time despite it being a dependency in a lot of hyperspectral applications.

With that in mind I have updated the code with the following:

  • a check for the presence of geographical information so that it works with non-georeferenced imagery, and
  • inserted machine into the fread calls for the bil and bip interleave cases to handle big-endian ordered data.

I = ENVIREAD(FILENAME) Reads an ENVI binary file into an array using the information from the corresponding header file FILENAME.hdr. The output structure I contains fields I.x, I.y, I.z and I.info containing the x-coordinate vector, y-coordinate vector, images data and header info, respectively. I.z will be in whatever number format (double, int, etc.) as in the envi file.

I= ENVIREAD(FILENAME,HEADERFILE); Uses the header information in headerfile. ' Thanks to Yushin Ahn for his modifications. NOTES: -Geo-registration does not currently support rotated images.

  • No support for importing complex data .
