Error creating buffer for feature SHALLOW
CoordinateTransforms.cpp - 3403
Version: v14.2.6 (32-bit)
Build Time: Aug 24 2013 13:12:47
I selected a single closed line, trying to keep it simple and still got the above error. Do you have any suggestions?
Thanks

What buffer distance did you specify? That error comes from a negative projection distance being specified, I'm just not able to reproduce it so far.

I selected an island and tried 300, 30 and 3. Same results.

Can you provide a sample of the data you are trying to buffer that generates this error? I'm so far unable to reproduce it.
Thanks,

I"ve attached a gmp file. In the middle of the bay is an island on the SHALLOW contour. If you turn most of the other layers off, you'll see it. That's the feature I was trying to buffer.

I cannot get it to reproduce, but I was messing around in the buffer stuff on the 24th, maybe you just got a half-baked build. Can you get the latest build and see if it still has the problem? I have placed a new build at http://www.bluemarblegeo.com/downloads/global-mapper/global_mapper14.zip with the latest changes for you to try. Simply download that file and extract the contents into your existing v14.xx installation folder to give it a try. If you are using the 64-bit v14 version there is a new build at http://www.bluemarblegeo.com/downloads/global-mapper/global_mapper14_64bit.zip .

Unfortunately, now the program just crashes. No text message, just shuts down. I also found the if I select 3D view, I get a blue screen. Do you think the problem is on my end. If so, any ideas what I should check?
Thanks

Frank,
I have made a new build to see if you get the same thing. Usually a blue screen has to come from a driver-level crash though.

I loaded gm's sample map, countries.zip. Picked an island of Hawaii and created a buffer. It seems the buffer works if the buffer size is greater than the island size. As once I specified a size smaller than 60 miles, it failed. Larger than that worked.
However, taking that concept to my map didn't work. I tried 300 miles, 30 feet both failed. The command still crashes the program.

I found it. I need to create a area to buffer. It was trying to buffer lines that failed.
Thanks for helping,

Frank,
This is still strange, it shouldn't really matter if you are buffering areas or lines, I just can't find a way to get a negative number down into the buffer creation code and buffers work fine for me of the size you say. I guess if you are interested in looking into it further I can add some debugging, otherwise I guess we can ignore it since you have found a work-around.
Thanks,
Mike
