From LIDAR Point Clouds to 3D Building Models
, 2009 High quality and dense sampling are two major properties of recent airborne LIDAR data which are still improving. In this thesis a novel approach for generating 3D building models from LIDAR data is presented. It consists of four major parts: filtering

Replicability of Digital Terrain Models and Canopy Height Models Derived from Drone Photogrammetry
Remote SensingReplicability of Digital Terrain Models (DTMs) and Canopy Height Models (CHMs) derived from drone photogrammetry is important to understand the extent to which time-series are exposed to methodological noise and conceal real environmental changes.

Irrigation and Drainage, EarlyView.ABSTRACT Accurate monitoring of crop water use is critical for precision irrigation, yet conventional lysimeter systems remain too costly and complex for widespread adoption. This study presents the development and field validation of a low‐cost, information and communication technology (ICT)‐enabled weighing lysimeter system that integrates load cells,

Drivers and Challenges of Micro‐Irrigation Adoption and Intensity in India: A Study of Four States
Irrigation and Drainage, EarlyView.ABSTRACT India's food security relies substantially on groundwater, but inefficient irrigation is seriously depleting this resource. Micro‐irrigation (MI) improves irrigation application efficiency and productivity, yet adoption remains low. This study examines MI adoption across four major Indian states—Uttar Pradesh, Maharashtra, Madhya Pradesh and ...
