View Full Version : using application in offline mode
05-20-2008, 12:01 PM
I'm new to develop an application which uses World Wind.
I need to run it in a public presentation, and during it there's no access to the internet. So I have to set offline mode, and I don't want to see the terrain blurring while I zoom. :confused:
I was thinking... can I download maps in my pc? Just the set for a specific zone! I hope I can. :D
Thank's a lot!

Best way is to set up your own server to sent the tiles to the WWJava application. There are several threads on that already.

If you navigate long enough over the area you plan to show during your presentation you will have everything you need in the cache. Being offline should still let you use that data.

thank you guys!
there's the possibility that i can't use my own laptop... so even if i store data in the cache by using application more and more in the same zone, the problem still exists. :mad:
I think that it needs to send tiles to JavaWW Application..
Can you tell me how? you said there are some other discussions about this topic but i can't found them... if you refer to one in particular, please can you link it?
I hope my thread wasn't off topic... if it is, I say sorry to you all...

Not sure i understand... if you have no network access and cannot use some local pre cached imagery... you may as well not use a computer altogether and use words to describe what users would see - just joking :).
Will you be able to instal and use a local server?

ah ah ah! You're right! It could be better :D
I think I 'm able to use a local server, can you tell me how do this?

Rather than set up a local server it may be easier to copy the cache from the computer you downloaded the images on to the computer you will make the presentation with.

And in case you haven't found the cache (I'm assuming you're using Windows), you can find the cache in "C:\Documents and Settings\All Users\Application Data\WorldWindData\Earth". As nlneilson suggested, you could just copy that data to your presentation machine. It's possible that this is a lot of data, but I think it's all uncompressed, so you should be able to zip it up if it turns out to be a lot of data.

Ok! Thank you so much!
Tomorrow I will try this strategy! ;)

It worked for me, so it should work for you too! Just be careful, the cache path for Vista is different: C:\ProgramData\WorldWindData (you may need to create the "ProgramData" folder, and there might be a space between 'Program' and 'Data', I can't remember right now).
