minimum heights

Discussion created by MalgosiaMendela on Jan 28, 2013
could you please give me instructions how to solve the following problem.
I have got X,Y,Z data and I need to create a line by joining points of minimum height values (local minimum heights).
Is there any tool in ArcGIS that would be appropriate for doing this I have heard about the module Spatial Analyst and one of its tool - Zonal Statistics, but I am have never used it before. I know that it recquires raster data so I need to create DEM first before I start any anlysis.
I wonder whether there is another possibility (tool available in ArcGIS) to solve this problem without creating DEM.     

I would be grateful for your help.
