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.

Three Tips to Reduce Personal Data Tracking in 2019

1. Switch to Firefox Why: You’re probably using Chrome right now.

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.

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.

For each recent episode you have options to: Listen (on same page) Add to Listen Queue (on same page) Download (Direct link to MP3 via Podtrac website) View a transcript

2017 Lambert St. Louis Airport Passenger Data

The St. Louis Airport recently released the 2017 information on passenger data. I really appreciate that they are releasing this information, but would love if the data was in a better format for working with this. To help others use this data, I’ve created GitHub repository where you can download this data. I’ve also created a few graphs based on this live data. The data is here: And I created a few graphs here: gavinr.
