  3. Spectroradiometry for Earth and planetary remote sensing

    en.wikipedia.org/wiki/Spectroradiometry_for...

    Spectroradiometry is a technique in Earth and planetary remote sensing, which makes use of light behaviour, specifically how light energy is reflected, emitted, and scattered by substances, to explore their properties in the electromagnetic (light) spectrum and identify or differentiate between them. [1]

  4. Land cover maps - Wikipedia

    en.wikipedia.org/wiki/Land_cover_maps

    Remote sensing satellite image processing. [3] This cost-efficient approach employs several techniques for image pre-processing and processing to accurately map land cover patterns. These techniques detect changes at various spatial scales following a series of machine learning simulations and statistical applications.

  5. Environmental monitoring - Wikipedia

    en.wikipedia.org/wiki/Environmental_monitoring

    Environmental remote sensing uses UAV, aircraft or satellites to monitor the environment using multi-channel sensors. There are two kinds of remote sensing. Passive sensors detect natural radiation that is emitted or reflected by the object or surrounding area being observed.

    The dataset has rigorously considered 4 environment factors under different scenes, including illumination, occlusion, object pixel size and clutter, and defines the difficulty levels of each factor explicitly. Classes labelled, training/validation/testing set splits created by benchmark scripts. 1,106,424 RBG-D images images (.png and .pkl)

  7. Remote sensing in geology - Wikipedia

    en.wikipedia.org/wiki/Remote_sensing_in_geology

    Richat Structure by Shuttle Radar Topography Mission (SRTM). Instead of being a meteorite impact, the landform is more likely to be a collapsed dome fold structure.. Remote sensing is used in the geological sciences as a data acquisition method complementary to field observation, because it allows mapping of geological characteristics of regions without physical contact with the areas being ...

  8. Near-surface geophysics - Wikipedia

    en.wikipedia.org/wiki/Near-surface_geophysics

    Electrical techniques, including electrical resistivity tomography, induced polarization and spontaneous potential. Electromagnetic methods, such as magnetotellurics, ground penetrating radar and transient/time-domain electromagnetics. Borehole geophysics, also called well logging. Remote sensing techniques, including hyperspectral imaging.

  9. Image registration - Wikipedia

    en.wikipedia.org/wiki/Image_registration

    In remote sensing applications where a digital image pixel may represent several kilometers of spatial distance (such as NASA's LANDSAT imagery), an uncertain image registration can mean that a solution could be several kilometers from ground truth. Several notable papers have attempted to quantify uncertainty in image registration in order to ...
