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.

There are free tools online that convert DWG to SHP. But we recommended using QGIS, which is an open source GIS software option.

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 – What’s the difference? LiDAR uses lasers to measure distances. Photogrammetry uses photos from different angles.

We used to draw maps by hand on paper. Now, we use digital mapping to make maps. Some call this process “computer cartography”.
