We've come along way with ArcMap and ArcPro since this video was made. Great demonstration, thanks!

Thank you for the short video combining kernel density and contour tool along with the link of the data.

Thank you!! (Our class uses your KZbin video as an example of how to do it! Also, I find it interesting that John Snow took time out of his daily routine of saving Westeros from white walkers and zombie dragons to help find the cause of the Cholera outbreak. A hero all 'round really wasn't he! ;-))

Hah! Pretty funny. Now we just need a density surface of the white walkers north of the wall!

Many thanks. I remember hearing about Mr. Snow's analyses in James Burke's excellent 1985 series "The Day the Universe Changed". Being able to work the actual data makes me feel part of history.

Absolutely! I'm glad you found it useful, and yes - working with these data is kind of a fascinating way to further explore history a bit on your own. It does really help bring it home I think.

Hi Chris, If you wanted to show density/kernal of multiple kinds of points (i.e. the density of pumps and deaths), is that possible?
@ChrisGoranson10 жыл бұрын
Culper Junior Hi Culper - if I read your question correctly you want to create a density surface of the pumps with the deaths combined? Technically you could merge the two layers together and create a density surface, but I'm not sure why you would want to do that. You might be interested in reading a bit about calculated rasters, which allow you to combine two (potentially weighted) surfaces together. Again, not clear that would work for anything of interest for this particular example, but they are powerful and the help within ArcGIS does a nice job of walking you through the details of such tools. Good luck!

Chris, I used the dataset in the given link but the density looks different on ArcGIS? Have the data been changed?

8:13 - 8:18 Can you manually make the box that surrounds the data points larger? I have a very large map with data points scattered throughout but the box is only including some of my data points because of the weight. Any advice?

Excelente muestra, que después de 1984, ha sido la base en la cual se ha sustentado el análisis SIG. hay posibilidad de que pases los datos?

I attempted to use this technique to display density using point data representing bicycle thefts. Instead of a graduated circle or glob shown in the video I repeatedly got big blue dark and light squares behind my city layer. I tried using kernel and point density and the results were the same.

Great video. Do you know how to perform a Network Kernel Density Estimation (NKDE) analysis using points and roads? If so, please make a video explain how to do it. Thanks in advance.

@aliatt28 жыл бұрын
Hi Chris, thanks for the tutorial. I used the tutorial and my results would give me kernel densities on each separate death incident instead of coming out as a group like in your case. Could you help me out?
