I'm going to work my way through the various documentation and work out what we need installed where on the dq server to have the maps working the way we want and get that done. The bulk of the work will be turning our maps into the images that google maps needs. The google code includes displaying a scale (in feet and metres) so we should aim for our maps to match their scale. Google maps are a series of 256x256 image files, the scale and starting point of each file depends on the zoom level. As I understand the zoom scale, at zoom level 0 one 256 x 256 pixel image covers the whole world. At zoom 1, the world is 2 256x256 images wide, etc. I'm assuming that at Zoom 0 256 pixels is 6,378.14 miles at the equator, and the following scales are based on this. There is a significant margin of error close to the poles at low zoom levels but I'm sure we can deal with this and most of the time we looking at scales where the margin of error is pretty small. NB I'm brushing over the http://en.wikipedia.org/wiki/Mercator_projection which they use to turn co-ordinates on a square map into coordinates on an oblate spheroid. Zoom Level, 256px=, 1px0, 3962mi, 15.5mi 1, 1981mi, 7.7mi 2, 991mi, 3.9mi 3, 495mi, 1.9mi 4, 247mi, 1.0mi 5, 123.8, 0.5mi 6, 62mi, 1277' (feet) 7, 31mi, 639' 8, 15.5mi, 319' 9, 7.7mi, 160' 10, 3.9mi, 80' 11, 1.9mi, 40' 12, 1.0mi, 20' 13, 0.5mi, 10' 14, 1277', 5' 15, 639', 2.5' 16, 319', 1.25' 17, 160', 0.6' Translating this.. The Alusia World map is around Zoom level 2 or 3. The image as displayed on this page: http://www.dragonquest.org.nz/dqwiki/index.php/Image:Brastor-Holdings807.jpg would be about Zoom level 6. Zoom level 17 would probably be reasonable for building floor plans. The other aspect of cutting up and naming our maps is the starting point (which I think is in pixels). At Zoom 0, the image starts at 0,0. At Zoom 1, the top left image starts at 0,0, the bottom right one starts at 256,256. At Zoom level 6 there are 4096 images making up the world and working out the coordinates to start at gets fun. Once I've read a bit more I'll confirm the coordinates method and naming convention, then we can start creating the cut-up images we need. Also, is Alusia the same size as earth? If not, what is its equatorial circumference? And if someone else could read the maps documents and confirm my scale that would be appreciated.

Hi all, In support of changing out DQ Maps to a Google map system format: I currently have a range of maps published in the Photo paint format (Corel Draw paint program). If people want to get any of these files (can be exported to a range of formats) from me and change or work on them you are most welcome too them. The are for the most part (90%+) the same as the map produced by Kelsie. The include a wide ranging area that can be found here as this 9MB download: http://www.parituhu.co.nz/jono/WK-Current.png If you wish to work on any part of this area I am happy to assist.

If not, what is its equatorial > circumference? We have tended to use real world figures for distance to horizon, specific gravity, mass of objects, sunrise & sunset times, etc, all for ease of calculation. It would seem reasonable to presume that Alusia is remarkably close to Earth for dimensions, gravity, mass, etc. Cheers, Martin ------=_Part_49343_18585105.1182748381648 Content-Type: text/html; charset=ISO-8859-1 Content-Transfer-Encoding: 7bit Content-Disposition: inline On 6/25/07, <b class="gmail_sendername">Stephen Martin</b> <<a href="mailto:stephenm@aklnz.net">stephenm@aklnz.net</a>> wrote:<div><span class="gmail_quote"></span><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> <br>Also, is Alusia the same size as earth?
