URL Cannot be Accessed and Cannot Find Metadata for Sun Azimuth and Sun Elevation #21

Open zakiindra opened 1 year ago

zakiindra commented 1 year ago

I tried to create a new dataset from other JAX aoi IDs, but I have trouble using create_satellite_dataset.py.

  1. The URL http://138.231.80.166:2334 for downloading the NTF files cannot be accessed.
  2. As an alternative, I downloaded the NTF files from https://spacenet.ai/core3d/ , but I can't find the value of NITF_USE00A_SUN_EL, NITF_USE00A_SUN_AZ, and NITF_STDIDC_ACQUISITION_DATE. Is there any other way to obtain those values?

Thank you.

Hello @zakiindra , I believe the url is up again.
In case it helps: I usually use gdalinfo to quickly check the metadata in geotiff image files from the command line. Sometimes the metadata may not be in the geotiff but in some associated xml file or similar. In create_satellite_dataset.py the metadata is assumed to be in the geotiff and it is accessed using the rasterio library. Best, Roger
