Remote sensing is the acquisition of information about an object or phenomenon without making physical contact with the object and thus in contrast to on site observation. Remote sensing is a sub-field of geography. In modern usage, the term generally refers to the use of aerial sensor technologies to detect and classify objects on Earth (both on the surface, and in the atmosphere and oceans) by means of propagated signals (e.g. electromagnetic radiation). It may be split into active remote sensing (when a signal is first emitted from aircraft or satellites)
or passive (e.g. sunlight) when information is merely recorded.
Overview
Passive sensors gather radiation that is emitted or reflected by the object or surrounding areas. Reflected sunlight is the most common source of radiation measured by passive sensors. Examples of passive remote sensors include film photography, infrared, charge-coupled devices, and radiometers. Active collection, on the other hand, emits energy in order to scan objects and areas whereupon a sensor then detects and measures the radiation that is reflected or backscattered from the target. RADAR and LiDAR are examples of active remote sensing where the time delay between emission and return is measured, establishing the location, speed and direction of an object.
Remote sensing techniques in archaeology are an increasingly important component of the technical and methodological tool set available in archaeological research. The use of remote sensing techniques allows archaeologists to uncover unique data that is unobtainable using traditional archaeological excavation techniques.
General techniques
Remote Sensing methods employed in the service of archaeological investigations include:

What is Active and Passive Remote Sensing?
Remote sensing is the acquisition of information about an object or phenomenon without making physical contact with the object and thus in contrast to on-site observation. Remote sensing is used in numerous fields, including geography, land surveying and most Earth Science disciplines (for example, hydrology, ecology, oceanography, glaciology, geology); it also has military, intelligence, commercial, economic, planning, and humanitarian applications.
There are two types of remote sensing technology, active and passive remote sensing. Difference between these two is quite small, however, leaves great impact on their functionality. As we learnt in primary school, sun constantly emits light energy and is only source of natural light for earth. Moreover, this energy is not observed by any com...

What is Remote Sensing and GIS?
"Remote Sensing vs GIS" is something that everyone in the spatial science realm had pondered about at some point in their life. And it was nothing different for me when I started a couple of years back. Hence, as I am restarting this channel, I want to provide a brief introduction on what is remote sensing and GIS - and their major types, applications and a few key terms (such as active and passive remote sensing, shapefile, raster and vector data, ArcMap, GIS mapping, etc.). Even though there are a lot of similarities, they are both entirely different science streams (more like sister departments).
Understanding GIS and Remote Sensing will help you figure out the right technologies and approach you will have to adopt for solving your specific research questions - and, who knows, maybe e...

Mapping the Invisible: Introduction to Spectral Remote Sensing
Did you ever wonder how your camera actually takes a picture? It's all about light - it records the light that objects reflect. This video explores the basic principles used by optical sensors like Landsat, AVIRIS, and other remote sensing sensors to record the things that we can't see with our eyes - like the health of plants on the ground. It explains the basic principles of the electromagnetic spectrum, bands and spectral resolution in data and the uses of spectral data to answer science questions.
