"A light detection and ranging sensor that uses a laser (light amplification by stimulated emission of radiation) radar to transmit a light pulse and a receiver with sensitive detectors to measure the backscattered or reflected light. Distance to the object is determined by recording the time between transmitted and backscattered pulses and by using the speed of light to calculate the distance traveled." (National Aeronautics and Space Administration, 2018)

Introduction

Land subsidence is a global phenomenon and is defined as:

“a gradual settling or sudden sinking of the Earth's surface due to removal or displacement of subsurface earth materials” - National Oceanic and Atmospheric Administration (2021)

Introduction

L’affaissement de terrain est un phénomène mondial et se définit comme :

"Un tassement progressif ou un affaissement soudain de la surface de la Terre dû à l'enlèvement ou au déplacement de matériaux terrestres souterrains" - National Oceanic and Atmospheric Administration (2021)

Mind the mapping gap between the ocean and coastal zones

Do you know that about 70% of the Earth’s surface is covered in water, yet it remains unmapped? As NASA oceanographer Dr. Gene Feldman said,

“We have better maps of the surface of Mars and the moon than we do of the bottom of the ocean.”

But can all these vast blue portions of the universe be explored and mapped like the Mars, which is 54.6 million kilometers away from us, but have nearly 90% of its surface mapped? "Well, that's the million-dollar question, isn't it?"

Remote sensing techniques for observing snow and ice

Introduction

Snow has a crucial contribution to Earth’s climate and helps to maintain the Earth’s temperature. When snow melts, it aids in providing water to people for their livelihood and affects the survival of animals and plants (National Snow and Ice Data Center). Approximately 1.2 billion people - constituting one-sixth of the global population - depend on snowmelt water for both agricultural activities and human consumption (Barnett et al., 2005).

Introduction to Lidar

Overview

This course provides quick and flexible access to several topics needed to understand the lidar landscape, what lidar is and why it is useful for management decisions. The course features engaging video and audio, optional knowledge checks, a final quiz with certificate, and assistive services for those with disabilities.

14th Geospatial World Forum 2023

Now in its 14th edition, Geospatial World Forum (GWF) has become a not-to-be-missed conference for the professionals engaged in geospatial and allied sectors. It is a collaborative and interactive platform that demonstrates the collective and shared vision of the global geospatial community.

ISPRS Geospatial Week 2023

The ISPRS will host the first Geospatial Week in Africa and Middle East in Egypt, 2023; with the the "Remote Sensing for Better Future". The ISPRS Geospatial Week (GSW) is a combination of workshops organised by about 30 ISPRS Working Groups active in areas of interest of ISPRS.The GSW will provide a platform for international scholars, graduate students, future scientists and industrial sectors to learn exchange knowledge and experiences of applying geospatial technologies for sustainable development for better quality of life for people around the world.

GEO Week 2023

Geo Week is the intersection of geospatial and the built world. The next step in the evolution of the International Lidar Mapping Forum (ILMF), SPAR 3D Expo & Conference and AEC Next.

9th International Conference on Remote Sensing and Geoinformation of Environment (RSCy2023)

The 9th International Conference on Remote Sensing and Geoinformation of Environment or RSCy2023 will be held in Cyprus on 3-5 April, 2023.

The RSCy2023 is organized by the Cyprus Remote Sensing Society in cooperation with ESA, NASA, Copernicus, DLR, Group On Earth Observations, the Department of Electronic Communications of the Ministry of Communications and Works, the Technical Chamber of Cyprus, the Cyprus Department of Meteorology and the Agricultural Research Institute.

The conference is published by SPIE.

Geospatial World Forum 2021

For over a decade, Geospatial World Forum (GWF) has been the premium geospatial industry platform that connects professionals and leaders representing the entire geospatial ecosystem.
