Create vertecs every 5m for interpolate shape from Lidar GRID?

[MichalEremy]

Hello all,

I want to create profiles form Lidar data (5x5 m grid) through 3D analyst in ArcMap.

My steps in toolbox: Fill, Fl. direction, Fl. accumulation, Reclasiffy,Str. link, Str. to feature, Interpolate shape.
I have one problem: I need to interpolate vertecs only, but vertecs are not every 5m. When the stream is straight for example 40m, ArcMap just make one vertec in 40m (see the picture).
Have anybody some idea to make vertecs every 5m? I have not check "Simplify polylines" in Stream to feature, but it doesnt help.

Thanks a lot.

Try following steps:

1. Use extract by mask tool and extract the pixels below the polyline.

ArcGIS Help (10.2, 10.2.1, and 10.2.2)

2. Convert the extracted raster to points  Using Raster to points tool

ArcGIS Help (10.2, 10.2.1, and 10.2.2)

3. Use the point to split the line using split line at point tool

ArcGIS Desktop

Hope this is helpful

Since you have a vector line, simply use the Densify Tool if you have the appropriate license level or this one if you are working with shapefiles

The Interpolate Shape (3d analyst) tool will resample at any desired density and defaults to the same as the underlying raster cell size.
