Aerial photogrammetry is a basic method for gathering and interpreting spatial data and by using aerial imagery to gather geospatial data, this technique makes precise mapping, surveying and analysis possible. From infrastructure construction and catastrophe management to urban planning and environmental monitoring, aerial photogrammetry is essential to many different industries. Different aerial photogrammetry techniques are …
With the introduction of innovative technologies, the agricultural landscape has undergone a dramatic transition in recent years and the use of drones in agriculture is one such innovation that has become rather popular. Precision agriculture has been ushered in by unmanned aerial vehicles (UAVs) which have changed traditional farming operations with their advanced sensors and …
Aerial photogrammetry is a process that involves the collection and interpretation of spatial data from aerial photographs where these photographs often captured by remote sensing devices mounted on aircraft or unmanned aerial vehicles (UAVs) serve as the foundation for generating accurate and detailed spatial models. The key to the success of aerial photogrammetry lies in …
A geophysical technique called ground penetrating radar survey (GPR Survey) uses electromagnetic waves to image and assess underlying objects where the system is made up of a receiver antenna that captures the reflections or echoes from various subsurface materials and a transmitter antenna that sends radiofrequency pulses into the earth. GIS experts can produce intricate …
The concepts of triangulation and stereoscopy are the foundation of photogrammetry where triangulation entails calculating the angles created by the point being observed, another point with known coordinates and a camera. Contrarily, stereoscopy uses minute variations in perspective between two photos taken from various angles to produce the illusion of three dimensions. What is Photogrammetry? …
The field of Geographic Information Systems relies heavily on satellite imagery to collect, analyze, and interpret spatial data. Satellite photography which is the process of using images from man-made satellites orbiting the planet to represent features or objects on Earth’s surface, has become an indispensable tool for numerous industries. Disaster Management and Response When it …
The term “satellite imagery” describes the picture of the Earth’s surface that is taken by imaging satellites in orbit around the planet where these satellites collect data at multiple wavelengths using a variety of sensors, including radar and optical ones, opening for a wide range of uses. Satellite photography has emerged as a crucial element …
Our everyday lives now wouldn’t be the same without satellite maps which offer a multitude of information for anything from environmental monitoring to navigation where satellite maps are essential for Geographic Information Systems because they provide an aerial perspective of the Earth. The visual depiction of Earth’s surface that orbiting satellites collect is called satellite …
Aerial photogrammetry is a cutting-edge method in Geographic Information Systems (GIS) that enhances mapping and spatial analysis with never-before-seen precision and efficiency and this cutting-edge technique produces incredibly accurate and detailed maps by fusing photogrammetric concepts, surveying and aerial images. What is Aerial Photography in Photogrammetry? Aerial photography in photogrammetry is a pivotal technique within …
A topographical survey is an intricate mapping procedure that records and depicts a landscape’s physical characteristics encompassing both natural and artificial components where making an accurate and thorough representation of the terrain’s surface is the main goal to facilitate precise spatial analysis and well-informed decision-making. Topographical surveys are essential foundations that offer priceless information for …
