Information concerning the DEMs Longyearbyen

[belletva]

I would like to gather more information about the DEMs Longyearbyen and I didn't found it in the documentation.

I propose to add in the documentation, some information about these two DEMs (1990 and 2009): Where were these DEMs obtained or downloaded from? (e.g., specific website, organization, or project) ? What technique was used to generate these DEMs (e.g., photogrammetry, lidar, radar, etc.) ?Were these DEMs derived from a single acquisition or multiple sources over time?

Thanks :-)

Good idea! That's for @erikmannerfelt to answer :)

Had a quick look into the link here in xdem-data: https://github.com/GlacioHack/xdem-data/blob/98004a09f84def4c78b253d41b212baca2b3cccb/download_data.py#L25

And it looks like this is the dataset DOI: https://doi.org/10.21334/NPOLAR.2014.DCE53A47

If @erikmannerfelt confirms, we can update this info somewhere.
