Time required to download/upload

Former Member over 15 years ago

I just bought a lifetime maps subscription and downloaded N America for the first time. It took 5.5 hours to download the file and almost 2 hours to extract, generate, and upload the resulting map to my 770. I have a Qwest DSL connection that averages 120KB/sec.

Is this normal? An entire day to update one map? :confused:

The file you were dowloading was quite large. It's just over 1 GB. Sounds about right to me.

Recently downloaded the same map, same result, thank goodness it's just once a year.

it's just the simple fact...large datasets take up a lot of space. I do a lot of GIS work and I can't even tell you how much time I spend downloading data at simply the state/county level. I think some datasets I DL run around 1GB for a whole state, so 1GB for the whole country is a pretty solid deal. Even 3GB for a continent is not too unreasonable. I don't wanna know how much time I'd spend downloading shapefiles for detailed roads info for the entire US.

And let's not even talk about satellite imagery. Usually around ~25mb per TILE for the high-res stuff I use. And I usually can't graphically select an area and just download them all at once. Usually have to get them one at a time due to the way the download sites are organized. Luckily, the browser/OS can usually handle several running at the same time.

Imagine trying to do these sort of downloads a couple of years ago :eek:

An option to provide the maps on DVD might not go amiss.
