IBM Drone Survey SOP 
Mining is the extraction of valuable minerals or other geological materials from the earth. The profitable substances that are mined from the earth are called minerals. The minerals are valuable in their pure form, but in earth they are mixed with unwanted rocks and minerals. This mix of mineral and...

Projected Coordinate Systems

The Projected Coordinate System helps you to project a specific round-earth model onto a flat surface or map. PCS are created by projecting the 3D GCS onto a 2D surface. The projected coordinate system tells the data on how to draw on a flat surface. There are many different map projection...

Drone Survey of Large Sites

Surveying large areas present significant challenges in terms of battery life, overlap, covering all areas, drone range, and safety. Most of the difficulties can be dodged by careful and intelligent planning. The amount of time and money invested in mapping is directly proportional to the area to be...

Guidelines for Automated Drone Mapping Part 2

We saw the initial planning phase of drone mapping in one of our previous blog. In this blog, we will discuss the Data Collection phase and how paramount it is to choose the right type of mission for generating results. It is determined by the terrain and the objects to be reconstructed.

Vector Data in GIS

The spatial characteristics of features can be stored in GIS in one of 2 ways: Vector data or Raster data.


Raster data is made up of pixels (also referred to as grid cells). Each pixel is associated with a specific geographical location. The value of a pixel can be continuous (e.g., Slope) or di...
