It gives complete information of high altitude photography and satellite photography. Images are recorded either on films or by recording the image digitally. Films used include black & white, true color, and Infra-red. In color photos, the red areas indicate live vegetation.

    Resistivity Method The BasicsWhy Do A Resistivity Survey?How Is A Resistivity Survey Done in The field?Induced Polarisation (IP) MethodWithout going into the physics of Ohm’s law, if you run a current through different materials you can calculate the electrical resistance by measuring the voltage and current applied. In practice this means that a resistivity survey will form an electrical circuit through the ground and take voltage and current measurements to calculate the resistivity of the sub-surface rocks.See more on geologyforinvestors
