Satellite imagery of the United States

Three image types, three different jobs

The default Esri World Imagery background helps you locate coastlines, cities and farmland. It combines images captured at different times; loading the map today does not make every tile a picture of today. NASA MODIS and VIIRS layers provide dated regional overviews through GIBS. USDA NAIP is a separate local layer: aerial photography collected from aircraft, not a live satellite feed.

1. Open the US map. Its selected outline includes Alaska and Hawaii, so the initial national view is broad. Pan and zoom to the part of the country you want to inspect.
2. For roads, fields and buildings in the contiguous United States, open Filters, choose USDA NAIP under Local imagery and press Update map. Zoom in if the map displays a zoom-required message.
3. For a dated regional view, use Fresh layer and the date control. Read the resolved source and imagery date: Auto archive may select an available date different from the requested day.
4. To compare the detailed background without a NASA overlay obscuring it, select No fresh overlay and press Update map. Turning off a fresh overlay does not change the acquisition date of the background or NAIP.

How to use NAIP without confusing its dates

NAIP is useful for inspecting field boundaries in the Great Plains, road patterns in the Midwest or developed coastlines in Florida. The layer served here covers the contiguous US, not Alaska, Hawaii or US territories. A missing local image there is a coverage limit, not proof that the whole map has failed. The underlying basemap remains a separate product.

NAIP collection follows agricultural growing seasons and different states can have different acquisition years. The date picker for NASA imagery does not rewind the NAIP mosaic. PocketWorld does not expose a verified acquisition date for every NAIP tile; use the provider's metadata when the year or exact date matters. Seam lines, season differences and image processing can make neighbouring areas look different without demonstrating a recent land-use change.

Regional observations and their limits

Across California and the western states, a broad NASA view can provide context for a smoke plume. Compare it with the US wildfire perimeter guide: visible smoke is not a fire boundary, and imagery is not an evacuation notice. At the Great Lakes, compare the same source and date convention when looking at cloud or snow patterns. Over Alaska, inspect available NASA and global basemap layers rather than assuming the NAIP selection supplies local aerial coverage.

Cloud, darkness, processing delays and provider errors can leave gaps or an older background visible. Read the layer's loading or error status before calling that view a successful current observation. More zoom does not add detail beyond the source resolution. These maps support geographic exploration, not navigation, property surveys or emergency decisions.

Check the original imagery information

Esri's NAIP tile-layer description explains the aerial mosaic and links its metadata layer. Consult the USDA NAIP Image Dates Data Hub for acquisition-date records. These are external resources, not a tile-date inspection feature currently embedded in PocketWorld.

NASA Worldview is an independent viewer for dated Earth-observation layers. Its overview imagery and NAIP's local aerial mosaic answer different questions. Record the source and acquisition date, not merely the time you opened a web page.

Weather loops and historical US imagery

For satellite weather imagery, use NOAA's satellite maps. They are a separate viewer; this PocketWorld page does not display a GOES weather-animation feed. For land-change research, USGS Landsat data access describes EarthExplorer searches by area and date, plus access to archived products. PocketWorld does not supply those archive downloads or a Landsat change-detection analysis here.

Continue with Live Earth for other Earth layers or Canadian imagery and radar-access guidance for a different regional workflow. The satellite orbit map shows estimated spacecraft positions, not photographs of the ground. Preserve imagery attribution when sharing a view.

Looking for reported aircraft positions instead of ground imagery? Open the US flight tracker for a sample over the mapped states, including Alaska and Hawaii. Read the US public flight-tracking coverage guide when an expected report is missing. Aircraft markers belong to that separate flight view, not this geography map. A NAIP capture year or NASA imagery date does not supply an aircraft’s report time, route, gate or flight status.
