Creating Moving Maps of the Goldfields

[BigWave]

Hi Prooz.
It will work if you have a good digital map (or image) and coordinates of points around the map.
They only give you a paper map, so you'd have to scan it first.
Here is one that I did last year of Dells Hole and Long Gully Stations.

I haven't done one of Western Creek.

Hi Dignit.
The MGA coordinates should both be the same as they both use the same GPS.
To test this, I have just driven to the local pub (The Grand in Warrandyte) so as not to show my home address.
No, I didn't have a beer (it's a Monday after all) - so will wait till lunch time
I then fired up both Handy GPS and Avenza's PDF Maps on my iPhone.
I loaded a local file (previously geo-referenced using GDA94) onto PDF Maps, and viewed the displayed coordinates on both.
They both display identical MGA coordinates.
Not just close - but exact.

They also showed the same image location (although one being a map and the other a sat image) - on the footpath exactly across the road from the car-park entrance.
So clearly, I didn't have the "wobbly boot" on when I geo-referenced my local area map.
Both apps are great - they just do different things.

Thanks for doing that BW. Much appreciated. That's very interesting.
I checked my Avenza Map (free version) coordinates on my phone against Handy GPS also on my phone and they showed vastly different coordinates.
However, just realised I was on the Getting Started page which obviously isn't showing correct coordinates, even though it shows a blue dot of my location in Victoria Australia.
Just want to make sure it works correctly before I shell out A$42.99/year for the Plus version which provides unlimited imported maps.
Cheers

Great info BW, I struggle with online mapping :argh: :beer:

Some of the best reading I have done in a while, Thanks.

Hey Guys,
Any luck with geo-referencing your maps?
Crow Pickens had a few issues, so he watched this video:

Seems to reinfirce the Coordinate Reference System (CRS) that I tried to hammer home, and shows a better way to geo-reference images (not maps).
Hope you are all catching on to this great way to geo-reference.
Please PM me if you're having difficulties.

Thanks BW, I haven't given up. Watching the video I think that will help a lot. Do you know if QGIS will work on an apple Ipad? as far as I can see it wont!
No GPS on my desk top. Still very interested to learn so will keep at it.

Hey BW I've only just stumbled upon this thread now and think it's ; 1 aewsome you know all this stuff, and ; 2 you're willing to share it with us! Tops :Y:

I'm going to have a crack at downloading all the nessary documentation as I need all the help I can get!

GDay BigWave I to have just found this topic and will try this on my Android powered tablet over Christmas. Thanks its been a very informative topic and I hope I can get it to work.

Thanks BW. This area of prospecting is very new to me, but it seems to be worth the effort of learning. Cheers, LenK

This thread has rekindled my interest in geo-referencing. My first experience with it was back in 2007, pre smart phone era, and I had an iMate PDA running Windows Mobile 3 and a purchased app called GPSDash. My scanned, or the then "newly" available purchased digital VIC topomaps were geo-referenced on a PC with the Apps companion software and then downloaded to the PDA.

Before a 4WD / Camping trip I would print out the VIC topomaps at full size. The PDA would be always be in moving map mode and when we wanted to know exactly where we actually were on the printed map (aka see the big picture) we could use the PDA as a position finder because the default zoom mode on the PDA conveniently matched the 100% scale on the printed map and it was a simple case of overlaying and matching the display image on the PDA with the relevant portion of the map. Post PDA I had began using MacGPS Pro until recently (it is now discontinued) to georef my GEOVIC custom maps and download trackfiles, polygons and POIs to my GARMIN Etrex. And then along came AVENZA sponsored georef maps which are brilliant but .......
