Hi,

 

 

I don't have experience in working with las file but I know that it is a point file.

 

 

So just a try, have you tried "PointConnector"

Hi,

 

 

Does the data have serial number (i.e:1,2,3)?

 

 

Is it possible to send sample data.

If you use a PointCloudCoercer to transform the point cloud to individual points you can then use a HullAccumulator to create a concave hull of those points. It's probably advisable to thin the point cloud first though (PointCloudThinner)

 


Hi!

How many LAS files do you have?

I would recommend using BoundsExtractor because it's easy to use. Here's a simple example below in which I take one .las file as input and create a extent polygon in a geojson format:

If you like you can also use a bufferer to produce a buffer polygon with 0 buffer and merge all those buffers into one single polygon.

In the following link I found a lot of transformers you can use on Point Clouds.

The BoundsExtractor only works if your LAS files are square and in a straight north-south and east-west line - otherwise the HullAccumulator suggested by @redgeographics is the way to go!
