Naming scheme mismatch for Whanganui rural aerials #635

Closed grantpearse closed 2 years ago

grantpearse commented 2 years ago

Hey LINZ team, I got an error parsing the latest datasets and looks like the s3 url path here for the latest rural dataset doesn't quite match the dataset "name" key here as it usually does. This is not a big deal as I can change key value pair I use when parsing the aerial.json but it would be great to know if they are generally expected to match or not before I make changes. Many thanks - Grant @ Scion Research

Hi Grant

This came about because we are looking at (eventually) dropping the linz-basemaps bucket in order to host one less copy of the imagery, and for the naming of the replacement bucket we dropped the rural/urban designation from the name. It is becoming increasingly difficult to define datasets as either rural or urban. e.g. we have datasets that are basically 50% rural / 50% urban in terms of the land-use for the area that they cover. Surveys used to be higher resolution over urban areas and lower resolution over rural areas, but as resolution has increased in rural areas, the line between the two has disappeared.

I would suggest removing the assumption that the two are going to match. They may end up matching in the long term, but it is more of a coincidence than an intentional design decision from us.

Thanks Daniel, yes I noticed the same with the big Auckland rural capture that was well above the usual rural spec. I will make the changes on our end and reach out to discuss the bucket changes with you if that is OK.
