The raster to polyline tool creates squares even with the option "SIMPLIFY". Is there a tool to create one line out of it this squares?

What were the other parameters set to? eg background_value, minimum_dangle_length

What was the cell size? and was this originally a float raster converted to integer?

 

PS The last time I saw that using "Thin" seemed to work

Hello,

the parameters are:

backgrVal = "ZERO"
dangleTolerance = 10

The cellsize is 1m, and yes it was a float raster converted to integer.

I will try thin tool, thank you for your help. I try to detect small ditches in flat wetlands.
