comment ArcGIS Kernel Density with polyline, search radius / bandwidth calculation
In the study area, rivers are important means of transport. So areas with higher river density are expected to see more of certain types of activity and visa versa. Given this, any thoughts on determining an appropriate search radius? Thanks.

Ah! I see what you mean. The points in this case represent towns. It would be ideal to have some value derived from other research that would help determine a meaningful distance. But that data is not available. Thanks for clarifying. I have gone back to client to get clarification and I'll post back when I know more.

Fair enough. However, the question I asked had to do with issues determining a search radius while using polyline features. If the number of features is a factor in determining the radius, what is the best way to handle lines where segment lengths differ (sometimes significantly so)?

To be honest, I'm not entirely sure how they will be used. I'm doing this work under contract and only have a few details about the project. My understanding is that the intent to create a measure of how "in the creeks" each point of interest is in. My assumption is that the extracted value will ultimately be used in a regression model, but I don't know specifics. Sorry, not a very satisfying or useful answer but I've only been given limited information at this point.

Sure. The polyines represent river features. There is a separate layer of points of interest. The intent of the density analysis is to create a raster file on which the points of interest file will be overlaid. The raster value at each point of interest will then be extracted using the Extract Values to Point tool. Thanks.
