Our topic will be "Using Google Earth Engine to Generate Monthly-to-Weekly Maps of Surface Water." The presenter will be Chris Soulard with the USGS Western Geographic Science Center. 

In this lesson we will provide a brief introduction on how to use The National Map Download Application. The TNM Download application allows users to explore and access the USGS staged products available for download. This application is a user-friendly version of the USGS staged-product application programming interface, and it is available on most platforms.

The USGS is pleased to announce the release of the National Hydrography Dataset Plus (NHDPlus HR) National Release 1 downloadable staged product. The NHDPlus HR National Release 1 presents a single, nationally continuous representation of all published NHDPlus HR Vector Processing Unit (VPU) datasets.

The USGS is developing the 3D Hydrography Program (3DHP) as the surface water mapping component of the new 3D National Topography Model (3DNTM.) The 3DHP will provide critical data to support a broad range of national, regional, and local applications such as flood forecasting and response, agricultural planning, infrastructure design, stream ecology research a

This webinar provides an overview of the Federal Fiscal Year (FY) 23 3D Elevation Program (3DEP) Broad Agency Announcement (BAA) solicitation and application process.

In this lesson, we will provide an overview and demonstrate how to use The National Map’s web services in a mapping application. Although downloading data from The National Map is a popular option for many users, there are numerous situations where it may be preferable to simply call TNM web services into your mapping application.

This lesson will cover Stream Flow Estimates in NHDPlus High Resolution. Enhanced Runoff Method, or EROM is the method used to compute estimates of the mean annual flow for the NHDPlus flowline features in the NHDPlus HR network.

 

This lesson will cover additional lidar point cloud processing and analysis features in ArcGIS Pro. If necessary, please review lesson 10b1 for guidance with importing LAS files, filtering, and visualizing lidar point cloud data in ArcGIS Pro.

This video tutorial shows how to use the National Map’s 3D Elevation Program (3DEP) Elevation web service in ArcMap. By the end of this lesson, you will be able to add the Dynamic Elevation Web Coverage Service to ArcMap, enable raster processing templates, and retrieve a spot elevation.

In this lesson, you will learn about the lidar products available through the 3D Elevation Program (which is abbreviated as “3DEP”). The lesson will introduce 3DEP, discuss the lidar data available, and where to find the data.

In this lesson we will examine a brief history of the USGS topographic map, Introduce US Topo maps and their content, discuss the production and future goals of US Topo, and learn how to access these maps for viewing or printing.

 

By the end of this lesson, you will understand the difference between the LAS and LAZ format, know where to download the laszip.exe tool, and how to decompress a LAZ file to a LAS file using laszip.exe. The USGS offers other lessons on using LAS files in ArcGIS Pro, Global Mapper, and LP360.

Welcome to the USGS course on Using The National Map Products and Services. This series of videos is focused on The National Map and the variety of products and services that it provides.

 

By the end of this lesson, you will be able to load multiple LAS files, define and use a polygon area of interest to subset LAS files, and generate and export raster surfaces and contours derived from the LiDAR point cloud.

This lesson will cover additional LiDAR point cloud processing and analysis features in Global Mapper.

LP360 is a family of tools for visualizing, manipulating and editing point cloud data and are offered both as an extension for ArcGIS, and as a standalone desktop platform for Window.

Global Mapper is a software package for visualizing, analyzing, manipulating, and exporting a wide variety of GIS data. By the end of this lesson, you will be able to open LiDAR point cloud LAS data files in Global Mapper, turn on all or specific LiDAR point Classes, visualize the data in 2-D and 3-D, and change the visualization using toolbar functions.

This lesson will provide a brief overview of the National Hydrography Dataset, Watershed Boundary Dataset and 3D Elevation program. This lesson will also discuss NHDPlus and introduce NHDPlus high resolution and tell you how to get the data.

 

This lesson will provide a brief overview of the National Hydrography Dataset (NHD), describe what features make up NHD, show how NHD functions as a national hydrographic network, and provide information on accessing data and additional resources.
