Garmin GPS Maps

Hello -

Pro version has the same road lines as the free version BUT also has additional features, i.e.

Capability to search for cities - and when we add them also other POI (Points of Interest.)


Polygons for lakes, dams, rivers, reserves, national parks, (wide) rivers.

For a visual comparison go to the files area at yahoo user group - you will have to join I think...

http://groups.yahoo.com/group/tracks4australia
coast/
and see the folder called Compare T4A vs T4A PRO

The advantage of using Shonkymaps/T4A relates more to using them on a Garmin GPS than a laptop I suppose. It is difficult to say what is best for any one person as it depends what your mapping requirements are - my only suggestion is get it and try - you can never have enough maps. Some people find Shonky/T4A adequate for their needs..others dont. It is the same data as used for 250K Natmap raster maps..but in vector format - you can zoom in and get better detail than visible on a raster map (despite same data set) ...but keep in mind scale of data capture and compromises in file size means some features are not accurately depicted at high zoom levels ie coast line, rivers and roads become "jagged" at highest zoom levels.

T4A is being slowly added to by people contributing track files to the developer (or you can do it yourself if you want) but process of addition and publication of new T4A versions appears slow - could be wrong but no new version has been released for a year or so - guy doing it may have bitten off more than he can chew - but full marks for trying and its certainly better than nothing.

Cheers
Greg

Hello Willie

I am sorry - the third link takes you to files section of the yahoo users group tracks4australia.....but you have to join first - which is why link doesn't work - woops.

Pilbara is half finished- I have done all the available 50K maps (200+) east of lat 117° 30'. Being doing a bit of field testing of late up near Port Hedland/Goldsworthy/Whim Creek and down around Juna Downs - good stuff though all the mining activity up that way means new railroads and tracks not on maps - topo is very handy though, plus older tracks (some overgrown) are shown. I hope to finalise balance of maps (200+) west of here by November. Process is being hindered by work commitments and cash flow issues:)

Cheers
Greg

east of lat 1171 30' =east of Lat 117 degrees 30 minutes

Hi Burnsy

When have tracks showing on GPS you press menu and list of options appears.

The bottom option is "Map Information"

When select it you should have short list of all mapsets in your GPS showing.

The ones ticked are active ones - so just check that shonky is only one ticked and it should work.
