ENVI hdr format Imagine compatibility

Hello,

 

 

When reading a hdr file pointing to a DEM from ENVI within Imagine, I observe a shift of the Imagine relative to its actual position. Is the hdr form correctly decoded by Imagine, or do I need to export it in another format (like GEOTIFF) ?

 

Please find an example of hdr metadata in attached file.

 

 

 

Regards

Re: ENVI hdr format Imagine compatibility

Hi Cheryl,

 

I got the same problem. It seems that Imagine doesn't read correctly the map info in the hdr. It takes the the coordinates of the tie point as the top left corner but it can be another location within the image. It is defined by the x/y coordinates (image space) just before.

Is there any solution for that?

I am asking that because I found the issue in APOLLO that uses the same librairies than Imagine for some image formats.

Thanks.

Hi Florent,

Is it a ENVI hdr BSQ  or BIP  format data? There are some problems related to projection and rotational information with those types of data in IMAGINE.
