Catholic Dioceses of the USA Map - Updated
I've updated the data and map of the Catholic Dioceses of the USA (originally posted a few years ago) - and it's much better now! For example, it now shows the Ecclesiastical Provinces: When you zoom in you see the dioceses: While updating and fixing the data set, I compiled some interesting notes about the Catholic Dioceses of the US: Ecclesiastical Province with the largest number of dioceses: Saint Paul and Minneapolis (10 dioceses) Ecclesiastical Province with the smallest number of dioceses: The Archdiocese of Washington (DC), is an Archidocese that has no other dioceses in its Ecclesiastical Province Largest diocese by area: Fairbanks (area of 401,823 square miles) Smallest diocese by area: Brooklyn (area of 179 square miles) Explore the interactive map here (or download an image)
Use the ArcGIS API for JavaScript with Svelte
My colleague Jacob and I have really been enjoying using the Svelte JavaScript Framework while building mapping web apps with the ArcGIS API for JavaScript. Here are a few links and resources that I've collected: Svelte with the ArcGIS API for JavaScript - Rene at odoe.net eats JavaScript libraries for breakfast and was one of the first to try out the Svelte framework with the ArcGIS API for JavaScript.

Trello Script: Find All Board Owners
I am a member of a Trello organization that is over its limit of free boards, so we're trying to clean up some old boards. The rules in Trello say that the board admin(s) are the people who can delete boards, but there's not a great place in Trello to get a concise list of all the boards in an organization and the details, so I wrote this little script.
ArcGIS JavaScript API Camera Helper
In a custom web map app, when creating your initial view, you usually start with the x/y (latitude/longitude) and an initial zoom level. When creating 3D web map apps that's a bit harder, because you have to worry about the camera tilt and heading too. To make this process easier, I recently shared a little tool … The ArcGIS JS API Camera Helper is a simple app that allows you to zoom to the exact location and camera tilt/angle that you'd like your 3D app to start with, then you can copy/paste the “camera” settings into your own JavaScript app, or generate a Codepen sample and start coding right from there.
Top 5 Interesting Basemaps of 2019
5. Charted Territory This basemap takes its inspiration from a printed atlas plate and pull-down scholastic classroom maps. (more details) Avo Patlong took this basemap and modified it into a “1950s styled” version. 4. Western Map Elizabeth Sutherland at the Western University of Canada created this map in the style of the WU school colors. (more details) 3. Seasons Andrew Skinner and the Esri Basemaps team put together a series of four basemaps, each one representing one of the seasons of the year.
Three Tips to Reduce Personal Data Tracking in 2019
1. Switch to Firefox Why: You're probably using Chrome right now. Google is the maintainer and distributor of Chrome, and have recently been making some decisions with the browser that are not in favor of privacy. Firefox has been making performance strides over the past few years and is basically as speedy as Chrome now, and is a much more privacy-respecting browser. How: Download and install the desktop browser.
St. Louis Imagery - 1990 to Now
What kind of changes to the built environment happened in your city within the past 25 years? Looking at and comparing aerial imagery can be an informative and compelling way to investigate changes. In St. Louis, many large building developments have happened over the years including: The St. Louis Arena Demolition The building and opening of Terminal 2 at St. Louis Lambert International Airport The demolition of Busch Memorial Stadium and the construction of the “New” Busch Stadium … and much more.
Getting the Microsoft US Building Footprints into ArcGIS Pro
Update: there's now an easier way to get this data into ArcGIS Pro. Please see the script that is linked in Arthur's comment here. Last week, Microsoft Released 125 million Building Footprints in the US as Open Data. This is a pretty exciting release of open geospatial data. If you go to the data download page and grab one of the state json files, if you try to load this into ArcGIS Pro with the JSON to Features tool, it's currently failing for me.
National Park System
If you look at all the National Parks across the US, there are about 60: The National Park Service manages many more “park units” other than just the officially-designated “National Parks.” These include things like National Lakeshores, National Monuments, National Parkways, National Preserves, etc. In total there are about 400 units across the US: The National Park Service has an open data portal where you can get an API of all the locations of these parks, so I took that data feed and put it into ArcGIS Web AppBuilder to create an application that allows you to filter the map by park types.
