Button to select latest ingested dataset #68

Open falkamelung opened 1 year ago

falkamelung commented 1 year ago

It would be nice to have a button that allows to display the latest ingested dataset. And/or a scroll window that allows to select one of the latest 3 ingested datasets - if we can do this in a way that not too much screen real estate is used

Do you mean the latest "last_date"? Or the latest table ingested?

If it's the latter, we don't record a time stamp of ingestion time in the database. I'll have to see if there's another way to get when a table was created in postgresql, but last I checked there wasn't a fully reliable way. I can research some more.

The latest dataset. This is what you call table, I suppose. I saw on the server a file which is updated every time a new dataset is ingested. But is it OK to open this file from within insarmaps?

It's not a high priority. I could simply create a little script to display the latest entries if you have no easy way to do this.

Which file is this?

falkamelung commented 1 year ago

Actually, it is not a file. But the entries in this dir have the relevant date stamp [insaradmin@insarweb tileserver]$ pwd /data/tileserver

Oh that is a good idea. We can use the mbtiles files as an indirect way to determine this.
