This is such an epic map, and used so often during Covid. John, another fantastic video - thank you as always. Keeping us GIS geeks "real".

I love your channel, John. It's so informative, and I've really taken maps that I produce for my job to the next level thanks to your channel. My only complaint is that you don't release videos more frequently! Seriously, thank you for all you do for people like me.

I made this same vertical stack map back in 2009 to get a GIS consulting job with our county health department. I also made several other visual displays of the same data to illustrate what I could do with the data they already had. Their in-house GIS guy was using ESRI at the time, and I was using Manifold. I'm not certain that, back then, ESRI had the tools to do everything that Manifold did, so I got the job. If you read the book about this bit of history, it explains why there are no deaths reported two blocks to the NE on Broad Street. That block was a brewery, and everyone there drank beer instead of water from the pumps. Another aspect of this detective work was that a clergyman in the neighborhood disagreed with Dr. Snow about the cause and set off to disprove Snow's claim by doing his own interviews to collect data. In the end the clergyman agreed with Snow and they combined forces to help end the problem. The problem resulting in the cholera outbreak at the Broad Street pump was disposal of diaper materials too close to the pump well. Pumps and cesspits did not have enough distance between them, and the clay used for the pipes was easily broken leading to cross contamination.

I used manifold for a while many years ago. Your approach to applying for the job sounds brilliant. Yes, I read the Ghost Map. Great book. I was astonished at how much poop there was everywhere in the urban environment. Basements filled with dumped raw sewage. And farmers who harvested the “night soil”.

Really cool map! and awesome content! Really appreciate the dives into the technical cartographic nuances in ArcPRO that your channel provides!

I haven't used a GIS program in 15 years; this video was obviously technically dense without being a drag for non professionals. Absolutely great at sharing information and inspiring design.

Thank you John for your view of the classic map. Most of us think at least about re-doing our own or classic maps like this one. I liked your colour choices for the map.

@ZorkoZerg 10 ай бұрын

A while ago I have suggested you to make a short video of layers from Living Atlas & ArcGIS Online you use in your maps, like Outline in this one. Are there any chances of making that video? Pretty please. 🙏

@JohnNelsonMaps 10 ай бұрын

thanks Zorko! i tend to shy away from red except for danger or warning. and this seemed like a topic that could accommodate red.

@JohnNelsonMaps 10 ай бұрын

i have been trying to highlight Living Atlas layers in my maps since your good suggestion. you might notice me adding Living Atlas content in almost every video.

Do you have any tips for creating fake data for maps? I'm working on a map of a fictional area and all the ideas I have for creating topography for them is incredibly tedious. Any and all tips are welcome!

@@JohnNelsonMaps That is a good technique. After watching dozens of videos from game programmers about generating terrain, I always wondered why no one somehow remixed real terrain. I suppose game programmers want to make their terrain much faster and more expansive than your average cartographer, though.
