GENERATE_EQUAL_VAL_AREAS / export vector not working

robin

Hi,

I wish to run through many TIF tiles and generate valid regions. Testing in the GUI I find 254 (all colours) will split a tif into white and black based on valid/ invalid pixels (Assuming white background=NULL).

But, when I script it I cannot figure why it is not exporting.

I tested the image load with image export function, so that works.

I try changing GENERATE_EQUAL_VAL_AREAS to GENERATE_LAYER_BOUNDS as it is much simpler, but the export does not work.. any hints?

Kind Regards,

Robin

Robin,

You need to add SHAPE_TYPE=AREAS to the EXPORT_VECTOR command for a Shapefile export as there are 3 separate Shapefile export types.

In the future, try running your script with File->Run Script and you should see a log of any errors encountered when running the script.

Thanks so much Mike,

I also found just changing the GMS to GMW permits to view the script at intermediate stages..

Anyway, the equal-area function is not behaving like I would expect. In the GUI, I set distance to 254 but when I set COLOR_DIST in the script is says only 0-128 are permissible?

Any hints?

Robin

This is from the script window... WARNING: The COLOR_DIST value must be between 0 and 128, it will be ignored.

Robin,

That was a bug in the script, it should have allowed 0-256. I've fixed that now. 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 .
