Types Of Remote Sensing: Technology Changing The World

Remote sensing is the acquisition of information about an object or phenomenon without making physical contact with the object and thus is in contrast to on-site observation. The term is applied especially to acquiring information about the Earth. Remote sensing is used in numerous fields, including geography, land surveying and most Earth science disciplines for example, hydrology, ecology , meteorology, oceanography, glaciology, geology ; it also has military, intelligence, commercial, economic, planning, and humanitarian applications, among others. In current usage, the term "remote sensing" generally refers to the use of satellite or aircraft-based sensor technologies to detect and classify objects on Earth. It includes the surface and the atmosphere and oceans , based on propagated signals e. It may be split into "active" remote sensing when a signal is emitted by a satellite or aircraft to the object and its reflection detected by the sensor and "passive" remote sensing when the reflection of sunlight is detected by the sensor.

Handbook of Satellite Applications pp Cite as. This chapter introduces the subject of remote sensing both in terms of its technology and its many applications. Remote sensing via satellite has become a key service that is used in many civil applications such as agriculture, forestry, mining and prospecting for many types of resources , map making, research in geosciences, urban planning, and even land speculation. Perhaps, one of the most vital uses of remote sensing today is related to disaster warning and recovery. The first use of remote sensing was essentially for military purposes and this remains the case today, and, thus, this chapter addresses these applications as well. Remote sensing, Earth observation, related Geographical Information Systems GIS , plus the interpretation and use of this type of data are today often referred to today as Geomatics. This section starts with a history of remote sensing and then continues with a discussion of the technology and its applications.

Radars and lasers are breathtaking attributes of sci-fi movies no longer as it was just a few decades ago. These innovations have been widely used as types of sensors in remote sensing since science made a giant step ahead. Over the span of time, remote sensing technology found their applications in various spheres of human life. Farmers benefit from the types of remote sensing satellites on a daily basis. There exist two main types of remote sensing classified according to the source of signal they use to explore the object, active vs. Active remote sensing instruments operate with their own source of emission or light, while passive ones rely on the reflected one. Each active sensor in remote sensing directs its signal to the object and then checks the response — the received quantity.

Below is the uncorrected machine-read text of this chapter, intended to provide our own search engines and external engines with highly rich, chapter-representative searchable text of each book. On command, all of them make measurements of the land surface, transmitting spectral data to a global network of strategically located ground receiving stations. Data from these earth-observing satellites are used to map, monitor, and manage the earth's natural and cultural resources.

Похожий на карлика бармен тотчас положил перед ним салфетку. - Que bebe usted. Чего-нибудь выпьете.

Он же давал им китайские значения, потому что такую задачу они перед ним поставили. - Господи Иисусе.  - Морант закашлялся.

Remote Sensing Applications: Society and Environment

Сьюзан встретилась с ним взглядом и прикусила губу. - Ничего, - выдавила. Но это было не. Терминал Хейла ярко светился. Она забыла его отключить. ГЛАВА 37 Спустившись вниз, Беккер подошел к бару. Он совсем выбился из сил.

Звуки шифровалки впервые за всю историю этого здания ворвались в помещение Третьего узла. Сьюзан открыла. Сквозь отверстие в двери она увидела стол. Он все еще катился по инерции и вскоре исчез в темноте. Сьюзан нашла свои валявшиеся на ковре итальянские туфли, на мгновение оглянулась, увидела все еще корчившегося на полу Грега Хейла и бросилась бежать по усеянному стеклянным крошевом полу шифровалки.

Две эти команды разделяло меньше одной минуты, но она была уверена, что разговаривала с коммандером больше минуты. Сьюзан просмотрела все команды. То, что она увидела, привело ее в ужас. С интервалом в три минуты была зарегистрирована вторая серия команд запирания-отпирания. Согласно регистру, кто-то открывал ее компьютер, пока ее не было в комнате.

 Да. Я решила ее издать. - Издать? - Он с сомнением покачал головой.  - Издать .
