Issues with Downloading High-Resolution DEM Data

[parker66]

Hi everyone,☺️

I'm currently working on a project that requires high-resolution Digital Elevation Model (DEM) data. I've been trying to download this data from the GeoWeb portal, but I'm running into some difficulties.

Specifically, any dataset larger than 1GB seems to be causing problems. The downloads either stop unexpectedly or the files become corrupted. I’ve already tried using different browsers and internet connections, but the issue persists.

Has anyone else encountered similar problems when downloading large files from GeoWeb? If so, how did you resolve them? Are there any specific settings or tools that could help ensure a successful download?

I also check this: https://geoweb.rsl.wustl.edu/community/index.php?/topic/2026-high-resolutilookeron-dem-of-lunar-south-polar-region/ But I have not found any solution. Could anyone suggest the best solution. Any advice or suggestions would be greatly appreciated.

Thanks in advance!🥰

Hi There,

I'm sorry that we didn't respond sooner. I am happy to help. Are you still having this problem? Is this an attempt to download through the Orbital Data Explorer (ODE) cart, the PDS Geosciences Website, or another location? A specific URL example would be helpful as we work out the issue. Also, is this over a wireless network or a wired?

Depending on the source location, I can provide some quick suggestions. If you are attempting to download from the PDS Geosciences Website, you could try Curl or Wget from our HTTPS locations, in addition to a web browser. We still support FTP downloads from the Geo website, which can be a convenient option, as well. When using the ODE cart, we provide the option to use the free Aspera high-speed data transfer plugin for your browser.

When you mention that files are "corrupt", what issue are you seeing? Do the expected md5 checksums not match those provided or the file is only partially downloaded? Standard PDS .img files may throw a corrupt error if double clicked in a Windows environment because standard Windows doesn't know how to open them. For more information on opening img files, see our FAQ https://pds-geosciences.wustl.edu/faq.html

Thanks,
