UAV Mapping for Aerial Surveying
UAV mapping has changed how we do aerial surveying. With drones, we can now map areas quickly, accurately, and in a cost effective way.
GNSS vs GPS: What’s the Difference?
GNSS vs GPS: GNSS is an umbrella for multiple navigational satellites. Under this umbrella, GPS, along with other systems, finds its place.
What Is Oblique Imagery?
While traditional images are taken from directly above, oblique imagery captures them at an angle. Learn more about oblique images.
Can GPS Work Without the Internet?
Can you use GPS without the Internet? Yes, GPS works without the internet. A GPS receiver works by receiving signals from satellites.
RADARSAT Constellation Mission (RCM)
The RADARSAT Constellation Mission (RCM) consists of three satellites. Using SAR, these satellites can see through clouds and darkness.
Understanding Sonar Technology
What if we could use sound to explore underwater? Sonar does just that. Simply, sonar turns sound waves into a map of the ocean floor.
Radar Bands in Remote Sensing
Radar bands are groups of wavelengths. Each has its unique ability to penetrate the Earth’s surface and reveal aspects of the environment.
What Are Waypoints?
As Tolkien once said, “Not all those who wander are lost”. This is especially true when we consider the role of waypoints in guiding paths.
LiDAR vs. Photogrammetry: A Guide to Mapping Technologies
LiDAR vs photogrammetry – What’s the difference? LiDAR uses lasers to measure distances. Photogrammetry uses photos from different angles.
