Xaquang Skyway / The Undercity.
There in the same part ow the map, only one is above the other. Do they count the Exploration % separately? --Poki#3 19:55, 1 July 2006 (CDT)


 * From what i recall, they are only counted once --Torins 12:33, 5 July 2006 (CDT)
 * I am sure that there is a part of skyway (NE river near south vizunah sealed exit) that you can only map via the undercity. I will have to check this tonight on a unmapped char. [[Image:AradaxSig.jpg]] 10:18, 2 August 2006 (CDT)
 * Having mapped the entire Skyway Section (Wall Hugging), and then mapping all north and north east section of The Undercity, this did indeed increase my % by at least 0.2%. This is from the south Vizunah gate where Guardsman Pei is located to the 4 clan fight just to the west.

Therefore the statement in Overview that "The undercity" does not contribute to mapping is false. 12:17, 4 August 2006 (CDT)

The Math..
Here is how the math was computed for Cantha:



For Tyria, I just approximated it based on the ratio of size. --Karlos 19:15, 5 July 2006 (CDT)


 * IIRC it took 4 'bits' of uncovering to get 0.1% in Tyria and it took 3 'bits' in Cantha. And it didn't seem to matter how big these 'bits' were. But I only started counting that once I reached about 99% and might have missed something, so could someone please verify that? --SET 14:50, 3 August 2006 (CDT)


 * This 'bit' thing is a bit shady. Sometimes you don't get a 'bit', but the edge of the area sharpens a bit or something. I don't think it's that simple to determine what is needed to get 0.1%. --[[Image:Gem-icon-sm.png]] (talk)

Difference Maps to Find Unexplored Areas
1) Obtain a 100% map.

2) Take a screenshot of your zoomed-out map in Guild Wars. Be sure to press Shift+PrtScrn to remove all icons. One thing you'll have to assure is that your map is the same resolution as the 100% map you're comparing to.  If it's different, an easy way is to open up your game options and change the resolution to the same size as the 100% map and take your screen shot.

2) Open up Photoshop and load in both the 100% map and your current map (found in your Guild Wars\Screens folder).

3) Once both maps are loaded into Photoshop, press CTRL+A to select your entire image and CTRL+C to copy, move over to the window with the 100% map and press CTRL+V to paste. In the Layers box down at the bottom right, you should see two layers - the 100% map at the bottom and your map above that.

4) Now we'll compare the differences. In that same Layers box, you'll see a dropdown menu saying "Normal." Click on it, and select "Difference." Before doing this, make sure you have your layer with your map selected.

5) You should now have a difference map. Dark areas denotes places which are the same in both maps (places you've defogged), and bright areas shows the places which are different (places left to defog).

7) If you want to check on any area manually, just go to the dropdown menu again (in the Layers box) and select "Normal." In the same Layers box, you'll see an eye to the left of your layers. Clicking it will turn your layer invisible, and clicking it again will make your layer reappear. Just zoom in on the area you want to inspect, and click the eye over and over again in quick succession. This will toggle your map on and off and will allow you to see exactly where the difference is.

8) If you're still having problems making out the differences between the two maps, save and make a copy of the inversion. Now take the copy, open it in Photoshop, and invert the colors.  Now instead of looking for bright spots, you'll be looking for all the dark spots. --&mdash;  xis10al   15:32, 4 August 2006 (CDT)
