reading geotiff images

[irfocus]

I had thought that geotiff images were simply tiff images with specifically formatted spatial (meta) information in the header and they could be read in as a standard tiff image without the header info.  Apparently I am wrong.  Labview will not recognize a geotif image in any of the image formats available.

Does anyone have or can suggest Labview tools that can read a 16 bit geotiff?  I would like to read the meta data but would settle for just reading in the geotiff image and displaying it, I can get the spatial information in other ways if needed.

Hi irfocus,

I was not able to find any easily implementable geotiff file support. The most useful information I found came from the following thread.

http://forums.ni.com/t5/LabVIEW/GeoTIFF-files-in-LabVIEW/td-p/417932

One user recommended saving or using the supported TIFF file format and then appending to that file using binary file I/O which would be rather involved.

I think a better solution would be to find a software that reads/writes geotiff files and that can be called by LabVIEW as either a DLL, or through ActiveX. I am unfamiliar with these softwares, however at the bottom of the thread a user has compiled and coded an example which reads the location data from a GEOTIFF file.

I hope this helps!

Thanks for the input.  It confirms what I have been discovering andi think I will concentrate on finding a 3rd party DLL and leave the idea of having my own version behind.
