Topo Map Update

Posted by Paxtar on 23 July 2016 in English (English)

I got a lot of good feedback from my original diary entry, after which I started a new version of my topo map. It's almost complete, and has turned out better than I expected, but not as good as hoped. I think I've corrected the worst of the problems that were pointed out. After several months of working on the project, it's become a bit of a chore, so other than some minor corrections, I've settled on this one as the final version.

I've been using a version that also includes an overlay with calculated likely waterway locations, as a background in JOSM. I'm hoping this will improve my mapping--once I get everything reorganized. I expect that will take a while, since I have many cities, towns and roads in places where they should no longer be.

Here is a screen grab of the topo map in JOSM showing what I'll be fixing. Larger version here.

It's currently a big mess. After fixing the map, it's on to the Wiki problems...

Wish me luck!

Awesome. I like how you did the elevations/contours. Good stuff you did.

I hope for the best.

Holy crap, what a great job. I'd like to get to the point where I can attempt something like this. What program did you use? Is that a JOSM plugin?

Wow, what an increase of detail in one month of work! Like what you did on your own.

@bhj867 Programmed with Java using Eclipse, I guess. All 2d stuff is possible to be made with the default Java installation on your computer.

Keep on the work. I am looking forward to topographize Gobrassanya!

I wrote/programmed several algorithms in Java using Eclipse (@Bstn thank you again for the Java help) that manipulated a data array of elevations. My starting point was a grayscale image that marked basic elevations. White for mountains, black for sea level, and shades of gray for hills and everything between. I applied a cloud-type fractal pattern to fill in detail, and then used simulated water erosion to add more detail. The output was created by exporting the elevation data to a colored image. The current version took about four weeks to complete. If anyone is interested in specifics, let me know.

I just downloaded the program. Would love a step by step tutorial. I want Pretany to go Boss. Would give me something to work with in correcting and detailing my forested areas.
