DESCRIPTION:**[GeoBlaze](https://geoblaze.io)** is a blazing fast raster an
 alysis engine written in pure JavaScript.  With geoblaze\, you can run com
 putations ranging from basic statistics (min\, max\, mean\, median\, and m
 ode) to band arithmetic and histogram generation in either a web browser o
 r a node application.\n\n### presentation\nThis presentation will go over 
 recent updates to GeoBlaze\, including the addition of support for Cloud-O
 ptimized GeoTIFFs.  We will also discuss the roadmap for the next couple y
 ears.\n\n### use cases\nGeoBlaze can be used wherever vectors and rasters 
 meet.  You can use it to calculate the hectares of wheat in a country\, th
 e change in daily median earth temperature\, and identify wildfires in sat
 ellite imagery.\n\n### environment\nBecause GeoBlaze is written in pure Ja
 vaScript it can be run in various environments\, on an EC2 server\, Lambda
  function\, Cloudflare worker\, or in the browser.  It performs calculatio
 ns using the CPU\, so it is not restricted only to environments where a GP
 U is available.\n\n### notable dependencies\nGeoBlaze is built on top of t
 he following open-source projects: [dufour-peyton-intersection](https://gi
 thub.com/GeoTIFF/dufour-peyton-intersection)\, [georaster](https://github.
 com/geotiff/georaster)\, [geotiffjs](https://github.com/geotiffjs/geotiff.
 js)\,  and [calc-image-stats](https://github.com/danieljdufour/calc-image-
 stats).\n\n### sample notebooks:\n- Time Series Analysis with GeoBlaze: Me
