I was just having a look at the BTOs new dataset on ALS and on the dataset page I can see that it has a whopping 13,064,724 records. I think Wow! that's amazing so I click on that number to look at them on the map. But then I see: 1,150,540 results for Data resource: Birdtrack.

I assume that's because it's restricting to Scotland.

If I was a user in Scotland I would probably have ALS as my default - how would I know/be able to access the full dataset? To the uninitiated it looks like there is bug in the system that's losing 11,914,184 records.

A better option, from my point of view (and I think Murdo highlighted this in a different form) is to not restrict to Scotland but to have the filters pre-set so that Scotland is 'ticked' but Wales/England aren't. I.e. have a country filter in the filters section.

(or is this all an artifact of not having the overarching atlas to supply the data..?)
