Comment: EOTopo

Thanks David. I do have the import option and have done quite a few imports from various formats.

While Memory map won't import ECW directly I can convert it to say Geotiff then import it.

The next question would be how large are the ECW files. When they are uncompressed they get very large.

For example I have an Australia map which is 700Mb, it won't uncompress and give me an error "Too large for TIFF file format"

Ah it sounds like you have done all this before. The Australia single file will uncompress to a small 80GB - yes 80GB. It needs some special gdal tools for BIGTiff support and as such you may struggle. The smallest maps for TAS is 1.3GB. I am compressing the Australia file now to send to Memory Map in GeoTiff and will let you know once it is in compressed Tiff format what size it is.

I have had these files reduced using a 256 colour reduction and GeoTiff compression down into the 4GB for the whole of Aust but I was not happy with the 256 colour reduction for my release on ECW and OZF as they work better using the 16million colours and having those tools work out the palette.

I will advise shortly once the compression is done and I will also try a compression with the 256 colour palette and see what comes out.

Just had a productive conversation with Will from MMap and I am sending over the source data for them to build a release so just give us some time and it will be made available in MMap. More details will follow once it is available.

Sounds great. I tried making a BigTiff file for my example Australia map that's 700Meg.

My I5 laptop overheated and crashed. It's pleading to me not to do it again....... Must be some serious number crunching going on there.

I would rather buy a properly supported map anyway.

I have been looking at you online version of the 200k and comparing it to 2 versions of the 250K that I have.

I guess the tracks and names are pretty much the same at the moment, but the colours and detail, like dunes and National Parks are quite a bit clearer on yours. It will be a nice product over time, especially when you add your new product next year which I assume will be similar to "places" here. Of course that will work with MM too. ( That's a statement, not question David...)

:-)

Oh yeah and if you do not want to stream the map in you can download the qc3 file (2.3GB) from here: crypt_EOTopo_200K_2014.qc3

David, I am travelling and only have Next g coverage but activated the 3day (!!) demo and it has good colour rendering.

I think I will buy it.
