Orthoimagery Data
Orthoimagery data typically are high resolution aerial images that combine the visual attributes of an aerial photograph with the spatial accuracy and reliability of a planimetric map. The National Map offers public domain, 1-meter orthoimagery for the conterminous United States with many urban areas and other locations at 2-foot or finer resolution.
The National Map Small-Scale Collection
The National Map offers a collection of small-scale datasets, most of which are at 1:1,000,000. The National Map publishes two data collections at one million-scale: one for Global Map users and one for National Map users. In terms of vector geometry, the lines, points, and areas in these data collections are identical. The difference is in the attributes assigned to these features.
WaterWatch
WaterWatch is a U.S. Geological Survey (USGS) World Wide Web site that displays maps, graphs, and tables describing real-time, recent, and past streamflow conditions for the United States. The real-time information generally is updated on an hourly basis.
