Each pulse becomes a precise three-dimensional point in space. When collected at high density, these points form a detailed “point cloud” that captures both the Earth’s surface and everything standing on it-trees, bu

It's a whole new frontier in analytics! This course explores the application of spatial data science to uncover hidden patterns and improve predictive modeling. Sign up for the (free!) Spatial Data Science course here: http://ow.ly/b6z250ypFHN | Esri

The United States and Canada are both modernizing their spatial reference systems. The National Geodetic Survey (NGS) is updating the National Spatial Reference System (NSRS) for the US, while Natural Resources Canada (NRCan) is leading a parallel effort to update the Canadian Spatial Reference System (CSRS). The NSRS and CSRS are fundamental frameworks defining geodetic coordinates (latitude, longitude and height). Modernization efforts aim to improve the accuracy and efficiency of spatial data
