Lesson 3b: The National Map Viewer Tool Functionality

The US Interagency Elevation Inventory, or USIEI, is a nationwide listing of known publicly available high-accuracy topographic and bathymetric source elevation data for the United States and its territories. The inventory provides a single resource for information about all known completed and in-progress broad-area public domain elevation data.

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.

This video provides basic information about the HydroLink Tool to get you up and running with the basic tool capabilities.

 

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.

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.

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.

 

The following series of lessons will cover how to use LiDAR data in the ArcGIS Pro environment. In this lesson, we will provide the user with an overview of how to load and view lidar files in the standard LAS format in both 2D and 3D.

In this lesson, we will describe the Watershed Boundary Dataset, show how the data are organized, and explain how the data are improved and maintained. Finally, we will show how the data can be accessed by download and as a map service.

 

By the end of this lesson, you will be able to use the Print tool and select Advanced options for printing the map shown in the National Map Viewer. 

By the end of this lesson, you will be able to use the draw tool to add data to the map and measure distances in the National Map Viewer. The next lesson demonstrates how to select data from the map, and take actions on it.

In this lesson you will learn how to download and install uGet. You will also learn how to use uGet to download data and maps from The National Map download Client using URLs saved in a text or CSV file.
