Review: EOTopo

ECW format will work with some versions of TwoNav but not all. Most importantly (for Nick at least) ECW files can not be opened with the Android version of TwoNav (and I suspect the iOS version as well). The only option is RMAP format (AFAIK).

I have used Twonav for several years on a Aventura (which does open ECW files). I have also a license for Android TwoNav on a Samsung Galaxy Tab3 10.1 and can assure you that ECW files cannot be opened and in fact don't even show up in the map list even if on SD card.

It is easy enough to convert ECW to RMAP using CompeGPS Land but this costs money to register. The trial version only last 30 days ..and I think Nick has exhausted his time before deciding on going down the Android path..hence his question to you. Obviously he could buy the registered version but for a one off conversion considers it uneconomic to purchase (though CompeGPS Land has other functions that he may find useful - but his call, not ours).

I realise that you cant supply every format for everyone (for various reasons) but I think Nick was hopeful you could assist in this instance (and possibly others in the future).

PS: reminder - Android TwoNav is also restricted to 2gb file size for maps.

Thanks Greg,

I was looking at some documentation - mind you the online documentation and information for the product is rubbish (unless I am missing it in searching). There would be a few issues with this conversion, I would have to convert the state based files as the main image is bigger than 2GB (about 3.5GB). This adds 6 more conversions to my growing list of about 6 formats already needing special conversion. I have not even been able to get Mud-Map to work as it just will not deal with the main map image and suspect it may have a similar 2GB issue however the MM guys have not mentioned this.

I can schedule the conversion in but then I have to buy the product, create another SD/USB drive for distribution, hold stock in the warehouse, update it when a new release comes out etc. This ends up costing a lot of time and money for how many users (I am not sure). If we were talking many 10 to 100's then I could do it but for a couple it is going to cost me more than I will ever recover.

GlobalMapper does not have a writer for it pity. Seems another propriety format for the sake of a propriety format.

A difficult one to answer easily without knowing how many users I am talking about, and that answer is not easy to find.

Hi

Yes, I pointed out to Nick (within a private discussion) that supplying every format for every possible option could be difficult proposition ..as much as you'd probably like to keep everyone happy.

I don't know how popular TwoNav is ...and then of course a percentage of users could do the conversion themselves (under assumption at least some purchase Compegps license) ...so risky business.

ECW is pretty universal and can be converted as well so best single option (as you obviously know). Strange that TwoNav doesn't have option for ecw on android. You can view ecw in Oziexplorer on Android so its not a limitation of the OS. Maybe someone needs to talk to Compegps crew and suggest they make the software more universal with respect to map formats.

Cheers
