Open Data in University City

I live in University City, MO, which has no crime. Don’t believe me? This map says so: Open Government The benefits of open government data - crime data being just one aspect of that - is well documented. It allows you and I to take the data the process it, innovate on it, be informed based on it, and keep our government officials accountable. It is easier now more than ever to have a basic open data program at any government level.

Extending Widgets in ArcGIS Web AppBuilder

I’ve had many requests and ideas for Web AppBuilder widgets over the past few years, and many times they are ideas that are building on an existing widget. For example, a query widget that is custom to a particular workflow, an edit widget that enforces certain geometry movement restrictions, or maybe adding a few more options to the built-in print widget. Most developers will copy the original out-of-the-box (OOTB) widget, rename it, and then start development from there.

St. Louis Bike Trails with Open Data from Great Rivers Greenway

2016 was a year of biking for my wife and me. We biked many trails in St. Louis, and even did part of the Katy Trail. So when I saw St. Louis City alderman Scott Ogilvie tweeting about Great Rivers Greenway, the trails organization in the St. Louis area, I started wondering what the future of St. Louis trails will be. Just send an email to [email protected] and let us know what you are looking for.

How to Create Pitch Charts with Python

A guest post by Gregory Brunner I have been interested in looking at MLB pitch data and play-by-play for a while now, however, I have not found any good blob posts or tutorials for doing this. So during the MLB Playoffs, while I was checking the score of Cubs vs. Dodgers, Game 5 on Yahoo! it struck me that there is probably a way to get the live game data from Yahoo!

OKSCAUG, Thunder Up!

By Gregory Brunner I was supposed to be at OKSCAUG in Moore, Oklahoma on Tuesday presenting on Mapping Russell Westbrook’s Shots with Python and ArcGIS; however, on Friday I fell through my garage ceiling and injured my left wrist, elbow, shoulder, and hip. Here’s the hole I left in the ceiling: It was a 10 or 12 foot fall. Amazingly Miraculously, the x-rays taken at the ER show no broken or separated bones!

Team Basemaps

Team Basemaps is a web app that allows you to choose your favorite team, cycle through the team colors to get the map looking exactly like you want, and then save it to your ArcGIS Online account to use in maps. It uses the Vector Tile Layers in combination with the new ArcGIS JavaScript API 4.0. I’d love to see your favorite basemap color combinations - post them in the comments!

Release Your New Web AppBuilder Widget in Four Steps

So you just wrote a great Web AppBuilder widget, and want to release it to the world so everyone can benefit.

GitHub CSV Import

Have you ever wanted to import issues from a different system into GitHub? I just released a new tool that will allow you to do that. All you need to do is get your issues into a simple CSV format including title, description, and the tags that you want, and the script will do the rest. To use, just install using npm install -g github-csv-tools and then run githubCsvTools myFile.csv from the command line, referencing your CSV file that you want to import.

How to Map the Infrared Universe with Astropy and ArcGIS

A guest post by Gregory Brunner I love astronomy. In a previous life, I was fortunate to study astronomy and work with some of the coolest hyperspectral data collected by the Spitzer Space Telescope. So since joining Esri five years ago, I’ve had it on my mind to use ArcGIS to map the infrared universe using observations from Spitzer Space Telescope; observations with which I already have some familiarity. Over the past few months I’ve been exploring the various Python packages that I could use for astronomy.
