GIS Spatial Analyst Tutorial using John Snow's Cholera Data

Want to work with the John Snow cholera data yourself? For a similar dataset see:

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.

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.

Thank you!! (Our class uses your YouTube 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! ;-))

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.

Thank you very much !!! Practical and easy tutorial.

[imranahmedkhan]

This is very good tutorial, many thanks for this. Can I get this data (shap file)?

[cosmos]

it was very helpful and i request you whcih software havw u used

[Zerojquan]

I am having issues with the hotspot, the circles cut off right from where my data ends.. how do I change it to show the full circles?

[bannongallaher]

Could you help me understand the output cell size you used, as well as the search radius? How do I know what values will be appropriate for my project?

[aliatt]

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?

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?

Hello
Can you help me by a question ?
What do you mean by the following traveler problem?

How do I learn GIS software effectively?

[CulperJR]

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?

From where to get/download this vector data

[ChrisGoranson]

Hi Jesus -

For a similar, downloadable dataset from Yale University see the link in the video description (I can't put links here in the comments).

Hope that helps,

Chris
