![]() Use SSMS to deploy, monitor, and upgrade the data-tier components used by your applications and build queries and scripts. SSMS provides tools to configure, monitor, and administer instances of SQL Server and databases. SQL Server Management Studio (SSMS) is an integrated environment for managing any SQL infrastructure, from SQL Server to Azure SQL Database. The National Map is the primary repository for USGS base geospatial data.Applies to: SQL Server Azure SQL Database Azure SQL Managed Instance Azure Synapse Analytics SQL analytics endpoint in Microsoft Fabric Warehouse in Microsoft Fabric ![]() and its territories by 2022 ( status map). Due to high cloud cover and remote locations, Interferometric Synthetic Aperture Radar (IfSAR)-rather than lidar-is being used in Alaska. The USGS hopes to complete collection of lidar data for all of the U.S. Lidar data is initially collected as a “point cloud” of individual points reflected from everything on the surface, including structures and vegetation. To produce a “bare earth” Digital Elevation Model (DEM), structures and vegetation are stripped away. Those pulses are reflected or scattered back and their travel time is used to calculate the distance between the laser scanner and the ground. The laser scanner transmits brief pulses of light to the ground surface. Light Detection and Ranging ( lidar) is a technology used to create high-resolution models of ground elevation with a vertical accuracy of 10 centimeters (4 inches). Lidar equipment, which includes a laser scanner, a Global Positioning System (GPS), and an Inertial Navigation System (INS), is typically mounted on a small aircraft.
