I’m working on GeoJSON and JSON data being pulled in and shown on the map. However, I just can’t get the data example from Sandcastle to work with my node.js server. I am working in Sandcastle in “DataSources” on the “Custom DataSource” example showing world population. I think it’s an awesome example!!
I am trying to replicate the “year” buttons with the population by year but I can’t get the buttons to work. It will load one year of data automatically from my json file but I can’t see how to get buttons on the screen so I could jump through the data by year.
I tried trying to find the js library to import with the Chrome tools but there are a LOT of libraries listed, I had trouble tracing back what is needed to make buttons that automatically populate like the Sandcastle example. Frankly, I would rather animate the data changes and show the year as a display but JS programming is not my first skill….
So then I tried using Gist on Sandcastle so I could at least upload the JSON files I made to see if they were readable but have been unable to put files into the Sandcastle server. It’s frustrating, I’ve spent a lot of time on this and can’t get anywhere.
I want to animate the growth of COVID-19 cases over time based on WHO data since I had employees who flew in from far-flung parts of the world and were quarantined in late March, and customers/family/friends were curious about the risks in the areas where they were, so I thought Cesium would be a good tool to use for illustrating that.
I also am going to model Iridium orbits over 3D terrain so customers can see if their mobile trackers are shaded by the terrain real-time. Iridium has real problems with terrain blockage when low on the horizon. I thought the COVID-19 example would be a good chance to become familiar with Cesium.
Maybe we can work on illustrating COVID-19 changes by geography together? A lot of people would like to see that.
We also launched a new satellite communication product that we are currently selling for emergency communications (the Flare, which turns your cell phone to a satellite phone) so was hoping a beautiful, easy-to-understand visualization might not only enlighten people on the disease spread but as a fringe benefit show people what we can do with data!
