Question: So I have a polygon feature classes with unique identifying names to them that I want to use to rename some other feature classes that are of the point feature type and have the same geography of one of the matching polygon feature classes. Basically the points from the second feature class fit within the polygon feature class. The point feature class has no name identify to it so I would like to change that and add at least part of the name of the polygon feature class to the name based on that fact they share the same geography. 

I was thinking I could use the Select by Location tool but the problem is I basically just have a bunch of unnamed point feature classes in a folder so it's not like I can select individual feature classes. So some how I need to iterate thru all point feature classes and rename them based on the polygon feature class they match up to. I'm guessing I may use Arcpy to do this. Any help or direction would be appreciated.

Answer: 
Cartographic rules to represent the relief as contours are presented in [Imhof's famous book on relief representation, chapter C](http://esripress.esri.com/display/index.cfm?fuseaction=display&websiteID=118&moduleID=1). Some of these rules are given on [this wikipedia page](http://en.wikipedia.org/wiki/Cartographic_relief_depiction#Contour_lines). The main recommendation when simplifying contours it to preserve the terrain main characteristics.

Smoothing the contours independently do not prevent them to overlap: It is advised to smooth the DTM first. A traditional Gaussian smoothing with a suitable parameter depending on the target resolution allows to erase the small details. A drawback is that DTM smoothing fills the valleys and depressions, and flattens the ridges and peaks. Using the douglass-peucker filter algorithm like [in this paper](http://www.isprs.org/proceedings/XXXVII/congress/1_pdf/129.pdf) may be a solution. There are also [number of methods](http://www.citeulike.org/user/jgaffuri/tag/contour) based on the use of contour smoothing algorithms constrained by the drainage network or a skeleton. Finally, to prevent the contours to overlap in sloppy parts, it is possible [to erase them locally](http://www.geos.ed.ac.uk/homes/wam/MackSteven2006.pdf) or also [deform them](http://icaci.org/documents/ICC_proceedings/ICC2009/html/refer/19_2.pdf).
I want to second @whuber's comment. Quantitative Analysis is always better from a DEM directly and Visual Analysis is often better when done from a Hillshade rather than contours. 

To answer the question directly:
In ArcGIS I would use either Focal Statistics or Aggregate [Spatial Analyst Toolbox] to smooth the resulting contour lines. Because contours are a visual analysis feature the amount of smoothing will vary on your need. So you'll have to experiment and see what works best for your project. 

Smoothing the lines after generating them does work but is a little clunky compared to modifying the raster first. One post-contour generation clean up I often do is to select the lines of a certain length (e.g. <10' long) and delete them. This rids the data of "noisy" little bits of closed contours (i.e. tiny loops) that are unlikely to reflect the actual character of the surface being modeled by the contours. 

Other things you might look at [ArcGIS users] are:

Making a Raster Mosaic and/or Focal Statistics Raster Mosaic and use a model to generate contours for the whole dataset. 

Making 3D contours for AutoCAD use. 

Watch out for areas of unusual DEM data (e.g. large expanses of low lying ground needing different contour intervals to accurately represent the surface, areas of dense vegetation giving bogus Bare Earth values, areas of vertical relief - cliffs, etc).
