There is a big difference between line density and kernel density estimation for lines. Line density in ArcGIS is easy to understand, but there is no information about kernel density estimation for line features. Do you know how kernel density estimations for lines (NOT line density) are calculated in ArcGIS? Thank you very much!

Dear Dan Patterson, Thank you very much for your reply. Still, the information you provided is about kernel density for points, do you have any idea of the principle of kernel density estimation for line data? Thank you very much!

ArcMap provides us a Kernel Density Estimation tool for both point data and line data. The principle of kernel density estimation for point features is easy to understand, it is the summation of densities of all points within a bandwidth around the focus point (Silverman (p.76)): But, how to understand the principle of Kernel Density Estimation for line data? The official website of ArcMap says that "the use of kernel function for lines is adapted from kernel function for point densities" (How Kernel Density works—Help | ArcGIS Desktop ), but there is no information about how this adaption is conducted. Could somebody help me understand the principle of kernel density estimation for line data? Thank you!
