I have downloaded the latest premium maps.
I find that the online maps are clearer and provide more detail (e.g. road names) than the offline maps at the same zoom level.
I thought they were the same.
I have sent details to Michelle but don't want to keep bothering her if the above is expected.

Level 14 in is an overzoom of the true raster image at the 144k scale so compare level 13.
There are technical output differences between the online system and the extracted raster data. Notwithstanding the different file compression algorithms in the georaster formats of the offline files.

Thanks Michelle.
Zoom 13 does look very similar.
If an over zoom would additional information be included.
In the online version street names are present which are not in the offline version

Just realised you aren't looking at/comparing the raster
EOTopo but comparing
EOTopo online/offline in the Traveller app. These offline maps are yet again a 3rd iteration of the data and use different file type/display methods which might account for very minor variations in some spot areas...its all rather complex being a database rule set that applies for all attributes consistently across the whole map regardless of outback or city.
I have just spoken with David to see if I could paraphrase something useful here but got too technical an explanation!

So you saying this is the way it is and nothing can be done about it.
I must admit I was impressed with street name details from online maps and a bit disappointed when not offline (not a lot just want every thing :)).
A bit if a pity as I don't use a SIM card in my IPAD which means it is only online when I am at
home.

Richard the offline 144k maps for
ExplorOz Traveller do have street labels but not every road at street level in Australia. Have you looked at other areas across Australia or just your
home?

Tried down in
Melbourne, Mt Isa,
Townsville,
Adelaide and all had the same inconsistency. i.e. not as many named streets and map display quality is not as good (this is at zoom 14). Zoom 15 online offers many more name named streets (understand offline only goes to zoom of 14).
I also understand this is not the main reason/function for the offline maps and I am happy to leave it at that to stop bothering you :).
I appreciate that you got back to so quickly.

Should not be a major problem if you can bluetooth or access online maps while driving in town, where there is reception, to get the greater detail. I assume that the offline maps at the higher online resolution would (with current technology) be an enormous download for the whole of Australia

My problem is my iPad does not have a SIM card so no online access unless I have WI-FI which is only at
home
I raised the issue as was not sure if what I was getting was expected or not.
