Mr. Sid has a new format? Guess they aren't using those around here. It has been a while since I have seen a sid.
Where can one download this file to try it out? Lizardtech makes side, right? Do they have a converter? Global Mapper works with just about everything.

It's the State of Montana GIS site. They put up the newer aerial photos, but they're in a newer format and my older programs don't recognize the format. Even lizardtech's Geoviewer 2.1 can't use them. The newer lizardtech's program does read them, but I can't get it to export them to a geotiff.
Here is a link to LizardTech. They are the creators of the MrSID compression technology.
They offer a free viewer that may export to different formats like TIFF.
Thats what we do is use Lizardtech Geoviewer to bring in Sid files and then convert them to .tiff files.
The nice thing is it holds the state plane coordinates and they drop right into LDD where they belong with our GPS points.
Whats works for us is bringing in a SID or multiples, and then just exporting the area we need - no edges then
When we export them we choose Format = Geotiff , Resolution = Full REsolution and we tag the "Write World File" also.
Works like a charm - this is version 5.50.3396 of Geoviewer
Not picking, but if you're running this on your XP machine you're likely closer to the minimum hardware requirements than the recommended requirements. Actually XP isn't even listed in their list of supported OS's.
Geoviewer System Requirements
You can run GeoViewer on 32-bit and 64-bit versions of Windows. GeoViewer supports the following operating systems:
- Windows Server 2012
- Windows 10
- Windows 8
- Windows 7
For optimal performance, verify that your system meets the following recommended hardware requirements:
- 2.5 GHz quad core processor
- 4 GB RAM
- 200 MB of disk space for installation and additional space for images
- SATA drive or better
However, it is still possible to run GeoViewer on systems with the following minimum hardware requirements:
- 1.5 GHz processor
- 1 GB RAM
- 200 MB of disk space for installation and additional space for image
Never let someone owe you more than you can afford to lose.
It's a brand new Dell with Windows 10, 500 G hard drive, i7 CPU, 16GB RAM, 64 bit. It took it nearly 2 hours to process a 150,291KB SID file into a 107063 KB Tiff file.
Resulting Tiff quality was equal to the SID photo.
Are you experiencing that amount of processing time?
I may have to raise hell with Dell.
