Satellite Remote Sensing has been a standard first step for the mineral and petroleum exploration industry. Satellite imagery from satellite sensors such as GeoEye-1, WorldView-2, QuickBird, IKONOS, ASTER and LANDSAT 7 +ETM have benefited geologists, scientists and exploration managers in earth sciences due to the advantage of large scale mapping and the sensors containing multiple band colors which allows them to interpret wavelengths that cannot be seen by the human eye, such as near infrared, short wave infrared and thermal infrared to identify the difference in structural features of the earth's surface.

This data could be utilized to interpret actual surface lithology to identify clays, oxides and soils from satellite images.
The use of satellite imagery in mineral exploration, generally a combination of panchromatic and multispectral image data has been used in mineral and petroleum industries over the last decade. With higher resolution satellite sensors increasing over the last decade such as GeoEye-1 (0.41m) and WorldView-2 (0.46m) both providing panchromatic and multispectral full color imagery that is used to utilize enhanced spectral analysis for mapping, monitoring and analyzing landcover classification and extraction of culture data, normalized difference vegetation index (NDVI) classification and mapping, lithological classification, change detection, environmental monitoring, development, land-use planning, visualization and simulation environments such as digital elevation models (DEMs) and 3d terrain modeling.
Geologists and Geoscientists have used satellite images to serve as databases from which they can do the following:
* Pick out rock units (stratigraphy) * Study the expression and modes of the origin of landforms (geomorphology) * Determine the structural arrangements of disturbed strata (folds and faults) * Evaluate dynamic changes from natural events (e.g., floods; volcanic eruptions) * Seek surface clues (such as alteration and other signs of mineralization) to subsurface deposits of ore minerals, oil and gas, and groundwater. * Function as a visual base on which a geologic map is drawn either directly or on a transparent overlay.
A well collated and structured data base integrated into a powerful GIS project can be used to collect and create valuable data for the planning and exploration program for:
1. The advantage of creating large scale area maps which allows them to examine in single scenes or in mosaics the geological portrayal of Earth on a regional basis. 2. The ability to analyze multispectral bands quantitatively in terms of numbers permits them to apply special image processing techniques to discern and enhance certain compositional properties of Earth materials. 3. The capability of merging different types of remote sensing products (e.g., reflectance images with radar or with thermal imagery) or combining these with topographic elevation data (DEMs) and with other kinds of information bases (e.g., thematic maps; geophysical measurements and chemical sampling surveys) enables views of existing or planning of proposed mines. 4. Mapping subregional surface geology. 5. Creating field exploration maps with detailed views of access roads.
Remote sensed data and GIS for mineral exploration is a key to management, planning and monitoring programs requiring on accurate information about the land cover in a region. Methods for monitoring vegetation and land change range from intensive field sampling with plot inventories to extensive analysis of remotely sensed data which has proven to be more cost effective for large regions, small site assessment and analysis.
