Svamitva - Empowering Rural Land Ownership through Photogrammetry

For years, rural land ownership in India has been plagued by disputes and confusion. The Indian government's Svamitva project aims to change that by creating a comprehensive land record system using modern technologies like RTK/PPK drones, and photogrammetry that documents ownership to potentially reduce land-related disputes. Svamitva stands for Survey of Villages And Mapping with Improvised Technology in Village Areas, and covers almost all of the 660,000 villages in India.

Improving Point Cloud Segmentation using Deep Learning

If you work in domains like mapping & surveying, infrastructure planning, or inspection, you must be familiar with the versatility of digital 3D modeling. Most of these applications require accurate segmentation of real-world objects to aid in decision-making. Unfortunately, this process can be time-consuming and costly, as manual correction is often required to compensate for the low classification accuracy from “automated” tools.

Creating Immersive & Large-scale Content using Neural Rendering

Generating photo-realistic images and videos is a challenge at the heart of computer graphics. Over the last couple of decades, we have come a long way from the pixelated graphics of Doom 1993 to high-quality renders like that of Red Dead Redemption 2 below. If you have played some of these modern games, you must have wondered how a beautiful and photo-realistic scene like the one below is rendered on your screen in real-time.

Digital Elevation Models (DEM): What are they and why are they important?

Digital Surface Models (DSM) and Digital Terrain Models (DTM) are top-down 2D representations of a 3D scene as an image with each pixel encoding both geographical coordinates as well as the elevation at that coordinate. They are often referred to as 2.5D representations of scenes. The DSM is a natural heightmap derived directly from a 3D point cloud while DTM is a bare-earth view with some natural (eg. trees, bushes) and all man-made features (eg. buildings, vehicles) removed, effectively depicting the “terrain” of the surveyed area.
