Hello,

 

I want to extract individual tiles/images with a fixed dimension (pixels x pixels) from an orthomosaic file (.ecw format), containing a single building in the centre of each tile/image. I do have a shapefile containing all building footprints but a can figure out how to approach this.

Can someone help me or give me some tips?

 

Thank you!

 

Best regards,

Bram

Hi @brmschipper, I would use the clipper with your inputs, just make sure that the footprints are buffered a bit so the you dont miss some info.

Hope this helps.


Generate a centerpoint for each building then use the 2DBoxReplacer to make a polygon centered on that point with the size you want, then use that as input for the clipper as @itay suggested.

I would use a BoundingBoxAccumulator grouped by the building id. Then scale them to your required size.

Thanks! Worked perfect!
