What are the base map services (or URLs) used in The National Map?
The National Map Services offers a series of composite base maps that combine layers into tile cache services with the cartographic richness of multiple data sources. The following base maps are available:
- USGS Topo - combines the most current data (boundaries, geographic names, transportation, elevation, hydrography, land cover, and other themes) that make up The National Map. Contours generated for the US Topo product are included and are visible along with other data to 1:9,000 zoom scale.
- USGS Shaded Relief - created using data from the 3D Elevation Program (3DEP), which maintains a seamless dataset of best available raster elevation data for the conterminous United States, Alaska, Hawaii, and Territorial Islands of the U.S.
- USGS Imagery Only - combines imagery from the U.S.; resolution may vary from 6 inches to 1 meter.
- USGS Imagery Topo - combines imagery with contours and other vector themes (boundaries, geographic names, hydrography, structures, and transportation), based on cartographic styling used on US Topo products.
- Hydrography - combines naturally occurring and man-made bodies of surface water, paths through which water flows, and related features such as stream gages and dams, and additional hydrologic information.

What is the difference between tiled and dynamic services? What is the difference between tiled and dynamic services?
A tiled service contains cached tiles that render the map in small tile images. This allows the map to perform much faster when panning and zooming, compared to a dynamic service. Dynamic is considered an "older" way of displaying web maps, where each feature is called from the source data and drawn separately for every pan and zoom. Tiled base maps are cached from global scale to a scale of 1:9...
What map projections are used in The National Map tiled base map services and dynamic overlay services? What map projections are used in The National Map tiled base map services and dynamic overlay services?
The projection used for all tiled base map services in The National Map is the World Geodetic System 1984 (WGS 84) Web Mercator (Auxiliary Sphere) so that base map services can be used in combination with other common viewers. See Spatial Reference SR-ORG:6928 and Spatial Reference SR-ORG:7483. Dynamic overlay services are in WGS84 (see Spatial Reference EPSG:4326) but can be reprojected as needed...

There are several imagery services for The National Map. Some imagery services are cached and some are dynamic: USGSImageryOnly (under Base Maps), for example, is a tile cache base map service of orthoimagery. It has different imagery data sources depending on view scale. The USGSImageryOnly service uses cache tiles of 256x256 pixels in size and 96 dots per inch (dpi) resolution with 75%...

Halema‘uma‘u eruption sequence Digital Elevation Models
Halema‘uma‘u eruption sequence Digital Elevation ModelsHVO uses regular Kīlauea summit helicopter overflights of Halema‘uma‘u crater to create digital elevation models (DEMs) of the crater. The DEMs show changes in the crater over time and can be used to estimate erupted volume, eruption rate, and map features of interest.
