In this blog, we’ll explore the importance of IMU in GNSS, how it enhances accuracy, and why it’s a game-changer for high-precision applications.

Learn everything you need to know about obtaining a Unique Identification Number (UIN) for drones in India. This step-by-step guide covers drone categories, DGCA regulations, eligibility, application process via Digital Sky, and the importance of drone registration for safe and legal operations.

Photogrammetry is the technology of creating 3D models, orthomosaics, point clouds, or other geospatial data from a series of overlapping photographs or images.

Surveying is a crucial aspect of civil engineering and construction projects, providing accurate measurements and data for planning, design, and implementation

The Government has updated the SOP for drone surveys and submission of Digital Aerial Images of Mining areas to the Indian Bureau of Mines.

Standard Operating Procedure (SOP) addresses guidelines for the drone pilot to follow during flight, pre-flight and post-flight procedures to ensure the highest degree of safety.

Surveying large areas present significant challenges in terms of battery life, overlap, covering all areas, drone range, and safety.

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

Drones have come a long way in the survey and construction sectors, and their capabilities have greatly improved

Vector data 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.

Raster data is made up of pixels (also referred to as grid cells). Each pixel is associated with a specific geographical location. Raster data is an abstraction of the real world.

Volumetric measurements are done using aerial or ground surveying techniques to calculate the volume of stockpiles and other materials.

Ground Control Points (GCPs) are defined as the points on the surface of the earth which help to georeference raster data such as satellite, aerial, or drone imagery.

Volumetric surveys are topographical surveys that accurately quantify the volume of material removed from or placed at a location.

Point clouds are the simplest form of 3D Model. They are the individual points plotted in 3D space.
