University of Washington Experimental Surface Water Monitor for the Continental U.S. Interpreting Satellite Images. Interpreting Satellite Images.
The radiometers flown on satellites are not cameras. Moving mirrors make the radiometer view different regions of the earth. The instrument begins by looking off in one direction and then scans across a scene making observations as it proceeds. In this manner the radiometer scans a scene line-by-line. Data is recorded in a two-dimensional format (line and element) which, when displayed on a computer monitor or television screen, makes up an image.
Interpreting. Time - Current time around the World and standard time zones map of the world- 12 format. Time Zone Converter - Time & Time Zone Conversion. Universal Coordinated Time and Zulu Time. NOAA satellites use Zulu Time or Coordinated Universal Time (UTC) as their time reference.
The satellite images that appear on NOAA's Web sites are stamped in Zulu time. To make the conversion to your local time, see the chart below. Find your local time in the first column. If you are on Eastern Daylight Saving Time (EDT), you would use the second column to find your Zulu Time/UTC. For instance, if it's 11 a.m. Latitude/Longitude Distance Calculator.
Meteorological Calculations and Conversions. SSEC - FAQ. The majority of satellite imagery that SSEC focuses on, such as GOES, NOAA polar satellites, Aqua/Terra, etc., is geared towards viewing Earth's meteorology, oceanography and climate and does not have the spatial resolution to see things like people or cars.
For example, the MODIS instrument on the Aqua and Terra satellites has a resolution of 250 meters which means that it can't resolve anything smaller than that. However, the WisconsinView organization which operates here at SSEC does work with high resolution satellite imagery that could be of use for observing smaller scale objects/places on the ground. Specifically, WisconsinView maintains a free online archive of civilian public domain color satellite imagery and aerial photos of Wisconsin with spatial resolutions ranging from 15cm (6-inch) to 250m (273yds).

Recap Of Google Earth Plus For Free Series. Now that I’ve *finally* finished the series on how to meet or beat most of Google Earth Plus’s features without paying for it, here’s a one-post set of links to all the posts in the series.
Google Earth Plus – Do You Really Need It? Brief summary of what features Google Earth Plus has, and which ones there are free solutions for. Importing GPS Data Into Google Earth I – Proprietary software and EasyGPS Importing GPS data into Google Earth using standard GPX files, proprietary GPS unit software, and EasyGPS. Importing GPS Data Into Google Earth II – GPSBabel and GPS Visualizer How to use GPSBabel and GPS Visualizer to download GPS data, and convert GPX and other GPS data formats into Google Earth KML format. Exporting Data From Google Earth To A GPS Unit Exporting point and line data out of Google Earth and into a GPS unit, something Google Earth Plus doesn’t offer as a special feature.
Using GPS Utility To Import/Export GPS Data To/From Google Earth Importing Spreadsheet Data Into Google Earth. GIS Interactive Map Viewer. USGS EROS Center is pleased to announce the upcoming release of HDDS Explorer ( On April 21, 2014, USGS is planning to release HDDS Explorer as the production system for serving disaster response imagery.
The current HDDS will not be available for use after this time. Any users accessing the current URL will be redirected to the new system.
