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...

Raster Data in GIS

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


Vector is a data structure that can be used to store spatial data. It is used to represent real-world features and assign attributes to those features. Vector data comprises of individual p...

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.


Data Collect...

Volume Calculation using Drone Survey

Volumetric measurements are done using aerial or ground surveying techniques to calculate the volume of stockpiles and other materials. Conventionally, it was done on the ground using total station but now, as an alternative, aerial UAVs are used to find the measurements. Surveyors now ...

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...
