Automatic terrain generation from geographical data (a tool I created)

[bustr]

In your tutorial the section about lakes at altitude, if you don't need really complicated shoreline shapes, you can use the new river path object. Create many segments then stretch their individual widths. The bed for it to lay on has to have the shores(boarders) flat so you don't get intersection interference from the surrounding polygons.

Here I ran one river and created several lakes.


 


Wanted to bomb a dam with a Lancaster.

when I created this program the lakes hadn't been implemented in AH, so... I need to do some/many  changes to the program

I still love the program Artik, its great!!!!

Just experimenting and get this error:

The file doesn't exist on the noaa site.  Is there a fix?

These files get moved every year or two. Look in the "download_sources.txt" file for the the sources list. You will need to do a web search for "gshhg-bin-2.3.6.zip" Once you find the new link-location, fix the line in the text file.
For every error, rinse and repeat.

One more note, latest download_sources.txt can be found on github there:

Replaced download_sources.txt and it is working fine now.  Thanks!

The last couple of terrains I've generated include very large areas of 1 foot elevation.  Is this due to insufficient elevation data in the SRMT3 dataset?  I've tried adjusting the solver_threshold.  Is there some other setting that would increase elevation resolution?  Is there a way to offset the 1 foot elevation areas to make them water?

The area I'm currently working on is:

lat=29.7
lon=116.0
scale=0.8

Thanks.  I've been having a blast with this program!

1st I suggest open another discussion rather than using this thread. What do you mean 1 foot. AFAIR I always add 100 foot to all ground area to make sure it does not become water see water_to_land_range/water_to_land_slope but in general can you describe your problem more precisely?

New Release 1.13

- Updated download sources with correct URLs
- Added support of OpenCL GPU platform selection for water optimization
- Added support of altitude offset according to user requests: altitude_offset parameter that is added to actual elevation
- Fixed grid for 256 miles map

thank you so much artik. i know theres only a few of us that use your terrain but we are really grateful!!! thanks for all you do to help us and the game!!
