Remote sensing, which consists of examining an area from a significant distance, is used to gather imaging and information remotely. This practice consists of using tools like drones to create topographic maps, detect algae, assess plant health, and more. There are various types of remote sensing that can be useful in environmental projects, which we’ll talk about in this article.
Common Types of Remote Sensing
While there are various types of remote sensing, each one is differently suited for analysis. While some methods are optimal for close scanning, some offer more advantages from greater distances. One of the most used types of remote sensing for environmental projects is radar imaging.
You can use radar imaging for critical safety-related remote sensing tasks. Weather detection and air traffic control are two essential uses for this type of remote sensing. Analysts use radar imaging to detect adverse weather, see how storms are progressing, and collect meteorological data. Law enforcement agencies also use Doppler radar to monitor driving speeds and traffic. Other types of radar imaging can be used to create models of elevation.
Lasers are another common type of remote sensing. Laser altimeters placed on satellites can measure things like the direction of ocean currents and wind speed. They are also useful for mapping the seafloor, as altimeters are capable of measuring the bulges of water caused by seafloor topography and gravity. You can create accurate seafloor maps by measuring and analyzing the variances in ocean heights.
LIDAR, or Light Detection and Ranging, is a specific form of laser remote sensing. It’s a method that measures distances by using light reflection, and it can also measure the height of objects on the ground and the number of chemicals in the atmosphere.
Other Types of Remote Sensing
While radar imaging and laser altimeters are the most common types of remote sensing you’ll see, there are a variety of other methods. Those methods include using multiple air photos to create stereographic pairs, which are often used to create topographic maps and view features in 3D. Photometers and radiometers can collect the emitted radiation from infrared photos. Finally, using satellites to obtain air photo data, like with the Landsat program, is another type of remote sensing that can be useful, depending on your project.
Remote Sensing Applications
There are many uses for remote sensing, but it’s a field of study mainly used for image interpretation and processing. Interpreting images that were obtained through remote sensing allows you to closely study an area without needing anyone to be physically present, which makes researching unreachable or potentially dangerous areas possible. And image processing allows you to manipulate photos to create maps and save important information about an area.
Remote sensing is a continually-developing sciency, and you can apply it to various fields, including:
Geology—Using remote sensing, you can map large remote areas. It makes it possible for a geologist to classify the rock types of an area, study its geomorphology, and track any changes caused by natural events.
Agriculture—You can also use remote sensing to study vegetation. It allows ecologists, biogeographers, foresters, and agriculturists to take photographs remotely to determine what vegetation is present, its growth potential, and the optimal conditions for survival.
Land-Use Planning—Remote sensing can help regulate land usage over broad expanses for those studying land development. This data is typically used for general modification of the environment and city planning.
Geographic Information System Mapping (GIS)—You can also use remote sensing as the input data from digital elevation models (DEMs). You can digitize air photos created through GIS into polygons for later use as shapefiles in the map-making process.
Because of remote sensing’s varied applications and its ability to easily allow people to collect, manipulate, and interpret data from otherwise inaccessible locations, it’s become a useful tool for researchers in a wide range of concentrations.
