ABSTRACT: The City of Cambridge has nearly 30,000 street trees that are maintained by the City's Department of Public Works (DPW). DPW was interested in reviewing their watering plans and also investigating tree mortality in relation to a tree's location. ArcGIS Pro tools and models were used with both LiDAR and 3D multipatch buildings to determine how much sunlight each street tree receives throughout the summer. As a way to make the results of this study more accessible to city staff, the solar rating is incorporated into the street tree data and displayed in a 3D web scene on ArcGIS Online.

ABSTRACT: This presentation will highlight how New York State is working with other County, State, and Federal Agencies on where to collect Elevation Data. A high level overview on how the data is reviewed for quality and accuracy using several different GIS packages. The end of the presentation will focus on all the products we make available free of charge. These products include bare earth DEMs, Hillshade, Contours, and LAS Point Clouds. We will focus on how we make all of this data available to the public via direct download and web services.
ABSTRACT: The National Oceanic and Atmospheric Administration (NOAA) and the U.S. Geological Survey (USGS) are gathering information from users across the Nation to improve the availability and consistency of 3D elevation data, including both terrestrial and bathymetric data, for the United States and its territories. The 3D Nation Elevation Requirements and Benefits Study will shape the future of Federal elevation data programs. A previous and similar study conducted by USGS in 2012, the National Enhanced Elevation Assessment resulted in the formation of the 3D Elevation Program (3DEP). The presentation will review the progress and results of 3DEP; provide detailed information about the information being gathered now; and an overview of how the information will be used to improve 3DEP in the future.
