Question

LiDAR to RasterDEMGenerator

J
Hi all,

 

 

Today is my second day with FME, so I apologize if my quesrtion is very basic.

 

 

I am trying to convert LiDAR (las) to DEM data (esri grid) but am having a problem with the interpolation. Any files that do not have adjacent las files to them - that is they are on the perimeter - interpolate all areas within their tile even if there is no data. 

 

 

Is there a parameter that limits the distance for interpolation or somehting similar? 

 

 

Thanks.

Please keep in mind that I do not have a project boundary etc. that can be used as a clipper. I'm wondering if this can be done without a clipper.

 

 

Thanks!

Hi,

 

 

If you read the LAS file without the point cloud coerder, than you automatically get the bounding box of the features, this can be used as a clipper after interpolating the DEM.

 

Hope this helps.

 

 

btw which transformer are you using to create the DEM?

Hi Itay,

 

 

Thank you for your response. Currently I am using the "RasterDEMGenerator" to convert into grids.
