Hi. I was wondering if there is a DRA overlay on any of EOz maps? Mainly for the Perth and further south forests.

Hello

Here are the DRA boundaries for SW Western Australia in GPX (data format for software applications) and KML (Google Earth) - I do not know if they can be opened in the ExplorOz Traveller App. - they work in OziExplorer and other mapping programs.





Cheers

GPX waypoint files can be imported as Private Places to your account which you can sync to ExplorOz Traveller however GPX boundary areas cannot as they are not GPX waypoints.

I think the DRA areas change too frequently for this to be a viable thing to add to the base map in EOTopo where we already have many other boundary areas such as forestry, native title etc. We have just compiled all this for the next release of EOTopo just 3 days ago so be quick if you want it in the base data then it can be - we just have to stop the map build and add it, and recompile - but be sure this is data that isn't going to change frequently. Greg maybe you can comment?

Hello Michelle

I don't really know how often they (DBCA) update DRA boundaries but don't think its is very often. The metadata statement says that it is "updated" every year (last updated on 2019-02-20) but that doesn't mean it actually changes...just that it is reviewed I suppose. The information is pretty handy as it shows areas where you cant drive (except on some main arterial roads) - so good for planning.

Cheers

G'day John L43,
Please excuse my ignorance, what is a disease risk area?

Hello

I think the main control is by trying to prevent unfettered access to vehicles but difficult (impossible in fact) to control give the number of 4WD/motorbike cowboys out and about who will ignore signs and destroy gates.

I just googled it.
It looks a huge issue.
It's a bit like the disease that can affect grape vines over here in the east (and probably other areas as well).
It relies on people doing the right thing, just like fruit fly control zones.
Unfortunately not every one does the right thing.

Yes William, it is a big problem over here in the west. I was out in the forests today and luckily one of my mates has the risk areas on his OziExplorer. Apparently it is spread much easier after rains, and it has been wet here, at last!!
Looks like you got your first questions answered.
