create a new polygon

Hi,

 

 

What is your definition of ' inside maximum polygon' ?

 

can you clarify that?

There's a few things you might mean, but it's difficult to tell from your description, so:

 

 

1) The LengthCalculator will get you the perimeter distance around your polygon.

 

 

2) The DonutHoleExtractor will extract any holes that are inside your polygon and then you can use the AreaCalculator to calculate the size of the hole and the Tester and maybe the StatisticsCalculator to understand which is the bigest hole.

 

 

3) The CircularityCalculator can help you to calculate the "circularity" of an area feature.

 

 

There's some options, feel free to provide a bit more detail as to what you are doing.

I extrac the edge of my raster with transformer RasterBandNodataSetter=0 and RasterExtentsCoercer. After that, i need to create a maximize inner bounding box of my image edge found with the rasterextentscoercer.

 

 

Thank for your help
