Understanding the Basics of the USGS National Map Viewer
The USGS National Map Viewer is an online platform that allows users to access a variety of geospatial data products provided by the U.S. Geological Survey. It includes topographic maps, aerial imagery, and other geographic information that are essential for both scientific research and personal exploration. To get started, familiarize yourself with its interface: you’ll find tools for zooming in and out, changing basemaps, adding layers, and measuring distances.
Exploring Different Basemaps
One of the first steps in navigating the viewer is to choose your preferred basemap. The National Map Viewer offers several options including topographic maps that show elevation changes and street maps that provide detailed road information. To change your basemap, simply click on the ‘Basemap’ dropdown menu located at the top left of the screen and select your desired option. Each basemap provides unique insights depending on what you’re looking for.
Adding Data Layers
The ability to add various data layers is one of the most powerful features of the USGS National Map Viewer. To access these layers, click on ‘Layers’ in the toolbar where you will find categories such as Hydrology, Boundaries & Land Use or Geology among others. By selecting different layers relevant to your interests or research needs—such as wetlands or wildlife habitats—you can enhance your map’s functionality significantly.
Using Measurement Tools
For those who need precise measurements while navigating through geographical areas within the viewer, measurement tools are invaluable. Located in the toolbar as well under ‘Measure’, these tools allow you to measure distances between two points or calculate area sizes directly on your map. This feature is particularly useful for planners or individuals assessing land use.
Saving Your Work & Sharing Maps
Once you’ve customized your map view with all desired layers and settings, it’s time to save your work. The viewer allows users to create custom maps which can be saved in various formats (like PDF) for future reference or sharing purposes. Simply go to ‘File’ then select ‘Save As…’ where you can name your project accordingly before exporting it.
With these tips in hand on how to navigate through features like basemaps selections, layer additions alongside measurement tools – you’ll be able to utilize all aspects effectively within USGS National Map Viewer. So dive into exploring America’s landscape today.
