How to split the Polygon into multiple polygons?

Hi, 

 

 

I have one big polygon. I want to spit the polygon into multiple based on the area. 

 

 

For example big Polygon (BP) has an area 500 sq.units. 

 

Then I need to have 5 polygons each with 100 sq.units.

 

 

I tried to use the Tiler but it is not functioning as I wanted to.

 

 

Thanks,

Hi,

 

 

what was it about the solution with the Tiler that didn't suit your needs?

 

 

Could you perhaps include a simple drawing / screenshot of what you would like to accomplish?

Hi,

 

 

just upload your screenshot to an image hosting service (e.g. Tinypic), grab the URL for the image and insert it into your post using this button:

Hi,

 

 

You need to use an URL that links directly to the .jpg, such as http://cdn.safe.com/community/attachments/http_download_1445975444514_11364.jpeg:

 

 

 

 

It is a difficult task if you have (very) irregular polygons and you need exact outputs. But if you only need to split them up into approximately(!) similar polygons, this might be something to try:

 

 

Send the polygons into a CenterlineReplacer, then use a Chopper to cut it up by suitable lengths. Send the chopped lines through a Bufferer, then use the Clipper on the buffers to avoid overlaps (hint: "group by"). You can then use another Clipper with the buffers as CLIPPER and the original polygons as the CLIPPEE.
