Notebooks

• Python
• R
• Julia
• ...and more!

• JavaScript

Why notebooks?

Example: Processing Runkeeper GPX Data

Jupyter

Examples: Query Raleigh CitrixCycle Data

Observable

• JavaScript notebook 
• Uses your browser's JavaScript engine as the environment 
• Change a cell, all dependent cells update (i.e. no hidden state)
• Some idiosyncrasies to fit JavaScript in notebook paradigm
• Still a very new project
• Active community

You might even get help from one of Observable's developers!

LiDAR Tools/Resources

• Entwine: Utility that tiles point clouds for more efficient retrieval and rendering
• Potree: Browser-based point cloud viewer
• PDAL: Utility for translating and manipulating point clouds (GDAL for point clouds)
• USGS 3D Elevation Program LiDAR Point Clouds
  • AWS Open Datasets
