Rotate first, then set the grid

I have been trying to get the latitude/longitude correct for Valencia, Spain - with a little trial and error I manage to set the box near PONTE-DE-SOR, PORTUGAL but when trying to move it further east the map will not show..., I assume my numbers are wrong:

Latitude: 39.2811
Longitude: -08.0005

try

39.4667
-0.3833

Perfect!

...I think this program is gonna' be my new best friend.

Just about any Lat/Long co-ords can be googled with something like

valencia spain latitude

and it pops up as the first entry

Let's try another one:

SALLA, FINLAND (previously called MÄRKÄJÄRVI).

Latitude: 66°49′59″ N
Longitude: 28°40′00″ E

What numbers to punch in? I end up in the Atlantic...

EDIT: Got it! This centers on SALLA:

Latitude: 66.8300
Longitude: 28.650

Love it!

There are some bandwidth limitations with openstreetmap where the images are loaded if they're not found in local or web site cache.

A new version will be available soon (hopefully) where you can just download the terrain map right away after placing the grid. It needs still some coding and testing and may not work in every location of the world.

If there's anybody interested in helping it'd be much appreciated. Some things to consider:

• User manual
• Testing
• Debugging

Especially some help file on how to enter coordinates, how to use the web app (entering coordinates on decimal format, rotating map, placing the grid on current location, what do all those buttons do etc.)

The map download system is getting pretty much ready soon, but will need some testing.

New version is out!

On the left hand side there's the zoom in/out control (mouse wheel works also, as does shift + mouse select)
On the right there's 5 functions from top to bottom (not all visible, hidden if they won't do anything):

• Return the map to normal orientation (north is up)
• Place the map grid on the current view center
• Turn map so that the grid is not tilted (game view)
• Download this map terrain file (see previous messages on how that works)
• Get link to this current grid placement (for bookmarking or linking)

It's now reworked so that it will use Google API for terrain data but Google limits the amount of requests so please don't use it too much. It also limits concurrent requests so map generation is limited to 1 map at a time. Creating a map takes roughly 30 seconds and it'll always be a 160x200 map. Downloading a map does not destroy your current view unless something goes wrong (and you're shown the error message).

Other controls: shift+alt+drag = rotate map (grid stays put unless you replace the grid)
