It is used to gather information and imaging remotely. This practice can be done using devices such as cameras placed on the ground, ships, aircraft, satellites, or even spacecraft.
Today, data obtained through remote sensing is usually stored and manipulated with computers. The science of remote sensing began in when Gaspard-Felix Tournachon first took aerial photographs of Paris from a hot air balloon.
The first government-organized air photography missions were developed for military surveillance during World Wars I and II. However, it was during the Cold War that remote sensing was most widely used. This field of study has developed since its beginning to become the highly-sophisticated method of indirect information acquisition that it is today. Satellites were developed during the late 20th century and are still used to gain information on a global scale, even about planets in the solar system.
The Magellan probe, for example, is a satellite that has been using remote sensing technologies to create topographic maps of Venus since May 4th of Today, small remote sensors such as cameras and satellites are used by law enforcement and the military in both manned and unmanned platforms to gain information about an area. Other modern remote sensing methods include infra-red, conventional air photography, and Doppler radar imaging.
Each type of remote sensing is differently suited for analysis—some are optimal for closer scanning and some are much more advantageous from great distances. Perhaps the most common type of remote sensing is radar imaging. Radar imaging can be used for important safety-related remote sensing tasks. One of the most important uses is for air traffic control and weather detection.
This can tell analysts whether adverse weather is on its way, how storms are progressing, and. Doppler radar is a common type of radar that can be used both to collect meteorological data and by law enforcement to monitor traffic and driving speeds.
Other types of radars can create digital models of elevation. Another type of remote sensing involves lasers. Laser altimeters on satellites measure factors like wind speed and the direction of ocean currents. Altimeters are also useful for seafloor mapping as they are capable of measuring bulges of water caused by gravity and seafloor topography.
Varied ocean heights can be measured and analyzed to create accurate seafloor maps. This method measures distances using light reflection and is most famously utilized for weapons ranging.
LIDAR can also measure chemicals in the atmosphere and heights of objects on the ground. Uses for remote sensing are diverse but this field of study is mainly conducted for image processing and interpretation. Image processing allows photos to be manipulated so that maps can be created and important information saved about an area. By interpreting images obtained through remote sensing, an area can be closely studied without anyone needing to be physically present, making the research of dangerous or unreachable areas possible.
Remote sensing can be applied to various fields of study. The following are just a few applications of this continually-developing science. Because of its varied applications and ability to allow users to collect, interpret, and manipulate data from inaccessible locations, remote sensing has become a useful tool for all researchers regardless of concentration.

Learn more. In this chapter, you will learn about various options for multispectral remote sensing data and the advantages and disadvantages of these data options. In the previous weeks of this course, you learned about lidar remote sensing.
If you recall, a lidar instrument is an active remote sensing instrument. This means that the instrument emits energy actively rather than collecting information about light energy from another source the sun. This week you will work with multispectral imagery or multispectral remote sensing data. Multispectral remote sensing is a passive remote sensing type. This means that the sensor is measuring light energy from an existing source - in this case the sun.
To better understand multispectral remote sensing you need to know some basic principles of the electromagnetic spectrum.
A spectral remote sensing instrument collects light energy within specific regions of the electromagnetic spectrum. Each region in the spectrum is referred to as a band. Remote sensing data can be collected from the ground, the air using airplanes or helicopters or from space. You can imagine that data that are collected from space are often of a lower spatial resolution than data collected from an airplane.
The tradeoff however is that data collected from a satellite often offers better up to global coverage. For example the Landsat 8 satellite has a 16 day repeat cycle for the entire globe.
This means that you can find a new image for an area, every 16 days. It takes a lot of time and financial resources to collect airborne data. Thus data are often only available for smaller geographic areas. Also, you may not find that the data are available for the time periods that you need.
For example, in the case of NAIP, you may only have a new dataset every years.This syllabus is divided into several sections. You can read it sequentially by scrolling down the length of the document. That being said, it is essential that you read the entire document as well as material covered in the Orientation. Together, these serve the role of our course "contract.

Niedermeier, A.Wildfires are a natural and essential part of our ecosystem, recycling soil nutrients and renewing healthy forests. In Alaska, around one million acres km2 burn every year, and record years have seen as many as six million acres burned.
Most of these fires are allowed to spread naturally. However, when wildfires occur near population centers, they can be a serious threat to the safety and well-being of people. Recent disastrous fire seasons in Alaska, California, and Australia have shown how communities near forests, in what is known as the Wildland Urban Interface WUIare increasingly at risk due to hotter and drier summer weather caused by climate change.
In the fight to protect these communities, remote sensing technology has become essential. Wildfire analysts use satellite imagery and powerful computer programs to predict fire risk, detect fires early, and monitor their spread.
After a wildfire is extinguished, remote sensing is used to analyze the impact of a fire and to guide sustainable restoration efforts. Students will learn about wildfire behavior, and get hands-on experience with tools and resources used by professionals to create geospatial maps that support firefighters on the ground.
