How to make this thematic map, and stuff

By John Nelson

One of the great joys of working here at Esri is the opportunity to collaborate with amazing people. Recently I had the opportunity to present at the User Conference about thematic mapping, with Sarah Bell and Kenneth Field. It was a lot of fun and we all surprised each other with what we made from the same source data. One of the most beautiful aspects of cartography is there is no one right way to make a map. Here is what I made with some election data that Ken supplied us with.

The title of this blog post says “How to” but actually it’s more like why to make this map the way that it is. There’s a lot to consider when making a thematic map, particularly election maps. This takes a pretty narrow look and mercifully uses data from Great Britain, which it turns out is not my home country. This was a nice change. Fresh eyes.

Here’s the video…

If you’d like to dive deep into all manner of thematic mapping techniques (it’s an endless path, my friends) I encourage you to check out Ken’s book on the subject.

Thanks for watching, and happy thematic mapping! Love, John

Hi Aziza, thanks for the article, this is great functionality and I’ve learned today that you can create a print service from ArcGIS Pro. However, as you will not be surprised to see someone ask, are there any plans to allow us to host custom print services in ArcGIS Online? We can potentially get access to Enterprise but in conversations with our Esri account managers they’ve generally tried to steer us away from this and suggest the use of AGOL instead. So when we see functionality like this that isn’t available in AGOL it’s a bit frustrating. Any updates would… Read more »

Hi Aziza,

Any news about reports in Near Me in ArcGIS Enterprise? Or a Feature Report widget for regular Feature Services? Or any upcoming support for Map Services in both? We really need reporting capabilities built-in in ExB for ArcGIS Enterprise.

Aziza,

Thanks for the great article! What would be the workflow if we only wanted a report with no maps? That’s actually a more common request at our organization, and I’d love to set a lot of those up for self-service.

Hi Aziza, thanks for providing a detailed workflow for publishing report templates to portal for use in webapps. I am wondering when we will have the capability of printing reports from selected features (and related records) in experience builder.

Thank you, Aziza, for this tutorial. I have been following the instructions here presented and have encountered the following issues: 1. Each Subreport starts with a new page which created excessive paperwork for a tool that has 7 layers with 7 subreports and each has one or two records per table. Is there a way to prevent the page jump between subreports? 2. The printing times of the tool when working with multiple layers are too slow, it takes the printing tool around 2 minutes to print which can be very frustrating for users. I have been trying to optimize… Read more »

Thank you, Aziza, for the excellent tutorials on creating a custom print service with reporting and for implementing it in Experience Builder. I’ve been mostly successful in implementing my own. I have an issue when I try to remove the data references as described in Step 4 of “Create a master report”. You mention that the easiest way to remove the data references from the project is to remove the map. It seems this is successful when I have about 5 layers. More than that, when I remove the map it seems that the data sources remain (I do not get the little red “exclamation… Read more »

Can this be published to a stand-alone ArcGIS Server 11.3 site?
How is this different from the workflow outlined here, that worked in older versions of ArcGIS Enterprise?

We are holding at 11.1 due to other integrations.
