closes #763

At https://www.digitalglobe.com/ecosystem/open-data/australia-wildfires under license it says:

OpenStreetMap Exception
In the licensing terms, DigitalGlobe has a stated exception for OpenStreetMap. OSM is allowed to use imagery released under the Open Data Program. Even though OSM enables commercial usage, OSM is a critical platform for the disaster response community. Allowing usage of our imagery in OSM will enable faster data access by local communities as well as global relief efforts.

What is this? A map of bushfires that occurred in 1920?

[vincentsarago]

😬 I guess the name Maxar 1920 Bushfires Pre-event should be updated to Maxar 2019/2020 Australia Bushfires Pre-even or something

[andrewharvey]

It cover's the 2019-2020 Australian bushfire season including the state of NSW only, before and after satellite imagery. Maybe I short-handed the name too much. Happy if it's extended.

[don-vip]

Maxar 2019/2020 Australia Bushfires is enough for me. I find "pre-event" hard to understand and translate.

[andrewharvey]

Though when more post event imagery is released it's nice to have both so they'll need different names. Does this need to be translated?

[don-vip]

In JOSM we translate all imagery names. Don't the other editors do the same?

[andrewharvey]

Ok so pre event means imagery from before the bushfires and post event means after the bushfires.

[don-vip]

ok thanks. It was especially difficult when I considered 1920 to be a date. With 2019/2020 it is easier to understand :)
