Know any photo editors that can handle the 16384x16384 water bmp?
I get to about 8000x4000 and I get memory errors if I try to change anything.
Any ideas?

I use Photoshop and Gimp2 both load them fine.

I couldnt find a hi-res (even as low as 4096) so I am having to make my own...

I was fairly proud of my Google Earth idea til I got the memory error.
:lol
Thanks for the GIMP2 idea, the latest download version allowed me to keep going.

I tried Gimp when my ancient copy of Photopaint stopped working after upgrading to Windows 7 and it is HORRIBLY unintuitive.

Quoted for truth.....you cant even downsize the damn thing. No matter what you do if GIMP is running the tool bar is showing.
On the other hand its the only photo editor I have found that lets me edit a 16386 square bmp.
-
Photoshop can handle a file that big but you only if you have the memory and CPU for it. Otherwise it is very slow loading and editing a 262 MB file.
-
Right now GIMP shows my file size for the image I am working on at 1.4 Gb.....
:uhoh
-
That would definitely do it. Basically it is trying to load 1.2 GB into memory.

It worked tho....
Proud to say I was flying around in San Fransisco harbor today, with shorelines taken directly from Google Earth.
800 miles of shoreline later....
:lol

Screenshots please? :)
I'm interested to see what is possible with the new editor.

San Fran is so big I can only show bits and pieces of it with screen shots.
Here is a Google Earth shot of San Fransisco....

Here is the water map of that area, slightly modified to give better presentation.

For reference the harbor is 50 miles end to end, the image you see here was cropped from a very large high-res bmp and scaled 50%.
Edit: The water map defines where the shorelines are, as it stands now I have most of the west coast modeled with nearly the same detail.

That's fantastic. At least I know my idea will eventually work then. I also thought of the google-earth, but figured the names of locations would be frowned upon.
So I scalped my image from Google Maps. I set the map for Satellite Imagery, then zoomed out until the country and city names disappeared. Then I took a screen shot (cntrl-prnt Scrn) and pasted it into a new bmp window (Paint). From there, I used the selection box to create a frame around the area I wanted to keep and copied the selection. I opened a new bmp window and pasted the clipped version onto the new window. Voila, I have a satellite image of the map I want without the clutter of the toolbars, headers, and city names.
My main problem now is understanding the scale to ensure that it will fit as a playable map in the clipboard, game, etc... I have posted a question about this in another thread. I hope to learn the answer so I can continue to develop a new map. I have (in my opinion) a great idea for a map and would love to eventually be able to send it to HTC for consideration.
Anyway, great job on creating the SF harbor. It looks great and I am sure interesting to fly in. Any help or tips toward creating my map (like you did yours) would be greatly appreciated. First and foremost, how did you get the grayscale elevations and how did you overlay them to accurately elevate your google earth map?
Great Job!

Greyscale elevation works like this.
You have 255 colors.
Each color is a step in elevation starting at see level which is black (rgb 0,0,0). The highest elevation is white (rgb 255,255,255). So one step above sea level is 1,1,1 and so on.
However, you have to realize the distance of the steps depends on your max elevation that you set when you import the grayscale elevation map. Even though it says 64000 is the max you can set actually it doesn't take anything above 32,000. So lets say you set your max at 20,000 ft. that is then divided by 255. So each gray scale change after 0,0,0 is a 78.4 ft increase in elevation ending at 255,255,255 which would be 20,000 ft.
If you set your max elevation when you import at 10,000 then each gray scale step would be 39.2 ft.
In the case of the map I was working on the highest mountain was 9,772 ft. so each step is 38.3 ft increase in elevation.
Although I think HTC code rounds the numbers so my examples really would be 78ft for 20K, 39ft for 10K and 38ft for 9772.
So for the U.S. find the highest mountain height for the continental U.S. and use that as your max elevation when you important your grayscale map.

And I'm proud to say I was flying around in San Fransisco harbor last weekend on my 2nd solo flight with shorelines taken directly from planet Earth.. :rock
Looking cool Strip! :aok

Wtg on solo Nova!
This is the final version of my land mass save small edits in the T.E.

Still debating on whether to go for one big terrain or several smaller better detailed ones tho.
