Aster satellite data

You can help by adding to it. A composite of bands in the short wave infrared displays differences in soils and rocks in the mountainous areas. Garcia et al used surface temperature and reflectance from ASTER images to study land degradation risk in a semi-arid region of Spain. ASTER provides high-resolution images of the planet Earth in 14 different bands of the electromagnetic spectrum , ranging from visible to thermal infrared light. Data are separated by telescope.

The resolution of images ranges between 15 and 90 meters. Retrieved 1 July Vegetation is red, urban areas are saatellite sediment in the bays shows up as lighter shades of blue.

ASTER Imagery

The instrument has been collecting data since February Temperature-emissivity separation algorithm applied to atmospherically corrected surface radiance data.

The color infrared composite uses bands in the visible and reflected infrared. Higher processes products may have costs involved. This section needs expansion.

Archived from the original on 29 May Archived from the original PDF on 21 July Level Product Description 1A Radiance at sensor Image data plus radiometric and geometric coefficients. Separation of materials is due to differences in thermal emission properties, analogous to colors in the visible. It is used to gather detailed data on surface temperature, emissivityreflectanceand elevation at a relatively high spatial resolution.

You can help by adding to it. These improvements include increased horizontal and vertical accuracy, [18] better horizontal resolution, reduced presence of artifacts, and more realistic values over water bodies. Expedited Level - 1AE 2A Registered radiance at sensor 1A data with radiometric and geometric coefficients applied 2 Decorrelation stretch Enhanced color composites for each telescope 2 Brightness temperature Radiance at the sensor converted to temperature 2 Surface radiance Radiance corrected for atmospheric effects 2 Surface reflectance VNIR, SWIR Derived from surface radiance with dtaa corrections 2 Surface kinetic temperature Temperature-emissivity separation algorithm applied to atmospherically corrected surface radiance data.

Classifies each pixel of polar scenes into one of eight classes: Use dmy dates from November Articles to be expanded from October All articles to be expanded Articles using small message boxes Commons category with local link different than on Wikidata. From Wikipedia, the free encyclopedia.

Data are separated by telescope.

Archived from the original on 3 July ASTER data are used to create detailed maps of surface temperature of land, emissivityreflectanceand elevation. The non-evaporative fraction as an indicator of aatellite function, Remote Sensing of the Environment, Vol.

Despite the high nominal resolution, however, some reviewers have commented that the true resolution is considerably lower, and not as good as that of SRTM data, and serious artifacts are present. ASTER gathers data in 14 spectral bands: Archived from the original on 4 July Archived from the original on 27 April You must have an account and be logged in to post or reply to the discussion topics below.

Australian Journal of Earth Sciences.

ASTER has a sun-synchronous polar orbit meaning it crosses over any given latitude ddata the same time each day. Retrieved 5 May Unlike the Landsat program xatellite acquires and archives all images, ASTER provides images on-demand and will only gather data on an area if a request has been submitted. This is a color coded temperature image of water temperature, derived from the thermal bands.

There might also be costs associated with acquiring some images.
