Large (1GB+) GeoTIFFs cannot be opened

I have several GeoTIFF files (orthographic images, exported by Pix4D) which fail to open as a layer, given an out of memory failure.

I have 64GB RAM on my Windows 10 desktop system, so I doubt it’s truly running out of memory in a 64-bit process.

Should Aspose.GIS be able to open large GeoTIFFs like this?

Hi, @kirkmarple

Thank you for sharing additional details. The file is a BigTiff format. Unfortunately, by the moment Aspose.GIS has no option to read data from the BigTiff format.

I have created a ticket GISNET-1266 and update you here as soon as additional information is available.

Please feel free to contact us if you have any other issues.
