How do YOU create various resolutions of the same map?

Redrobes,

Interesting. I really should check it out someday....it's only 'being stuck in the app' that's held me back since.

If I understand right, I can zoom out to encompass the whole map, export that at 20000pixels (or so) width, and it will include details that would resolve at that 20000 pixel resolution as though I'd had a 20000x____ window open and done a screen capture? (e.g., all the detail would be there)

I've found 30000x15000 or so is the max. size that compfortably works in -most- programs I've tried. Granted, I've not printed anything out that's 100 inches/50 inches, but you never know - I want to be prepared.

Do people need to own the viewingdale software to view the maps served on the web?

Thanks!

That is correct. It is NOT like a screen capture scaled up to 20,000 pixels, its, as you say, as tho you had a 20,000 pixel screen so that detail which would be at the 1 pixel res is still there in the export. I had a video showing that somewhere. If I find it ill link it.

EDIT - Here it is:

Its a bit long. Start half way through to see it save a 12,000 pixel image with 1 pixel detail.

Theres two modes of seeing a remote viewingdale map. You can a) use the VTT aspect of it where you locally generate the transferred map on your local copy of viewingdale. In that case you can modify the map locally and everyone gets the changes sent back. Its also super fast (realtime) scroll and zoom. For the VTT mode you need a copy. Or there is b) where you can set one master copy of viewingdale to act as a web server for the currently loaded map. In which case other people can use just a web browser only to request an image of the map at a set X,Y & Zoom and image size. In this case you can look at the map at different positions and scales but you cant edit it. You cant get a grid switched on or off or do very much. You just get an image. In a similar way that say google maps sends out tiles of maps to view but not edit. Note also this mode is served from the app not a web site. With your browser you need to ask for the image at your local IP address and do all the normal port forwarding for being a web server as opposed to normally being just a web client.

Using a combination of the two you can play the game with some people using a copy editing the map and have a couple of people using a web browser and they could use browser refresh to get a new image with changes made by the DM and other VTT players but he would have to request someone to move his characters icon.

If you have a static IP address and an always on windows box server then you could make web pages with links to your viewingdale web service so that you could have a wiki or a web based map and have links to map images which might change if you edited the map with the app. I.e. it would be a dynamic up to the minute view of the map areas without any need to FTP upload new static map images to a web site.

Hope that explains it.

Thank you for the great explanation!

Hello, a newbie here. I'd like to resurrect this thread.

Basically, I would like to use Google map API (or something that works similarly) to display both a country-level map,
and county, and then city-level detail. I made a largish map; and managed to slice it into tiles using the GMap Image Cutter.
The resulting Google map javascript-based API is very convenient. But even on my relatively small map,
the labels don't really work -- they are either too large or too small. Other problems have been noted upthread:
there is no feature discrimination, and roads (when I have them) and streams disappear at smaller scales.

Does anybody know a way to host zoomable maps on a generic web hosting site,
without a large investment in GIS software and data entry? Any pointers to further research would be welcome.
