Color stream segments by attributes (assigned and extrapolated)?

Discussion created by dbrooksf on Mar 29, 2011
I have multiple samples along a stream segment (pulled from NHD) from which I'd like to extrapolate to create a gradual color scheme of a single stream. For example, say I'd like to color code the stream by temperature measurements, in which red colors would represent relatively high temperatures and have a gradual progression of colors down to blue, representing low temps. I'm assuming a similar analysis has been done, but I don't know what to search for in the forums because I'm not sure of the correct terminology for such an analysis.

More specifically, is there a way to evenly divide up stream segments and assign a value (temperature in this example) automatically? Is there a tool that will assign values to stream segments by extrapolating between line segments which have an assigned value (temperature in my example). I'm thinking something similar to creating contours in a raster, but for a single line instead.

Any suggestions would be much appreciated!
