GICHD: Using GIS for Clearing Landmines and Restoring Land to Use

Friday, September 13th, 2019

With all the uses that have been discovered for GIS, humanitarian demining is one that has not gotten a lot of attention. Land mines and unexploded remnants of war are embedded in the soil and structures of one-third of the world’s developing countries. These abandoned time bombs affect innocent people long after the war has ended, making so many areas uninhabitable.

GISCafe Special Report Questionnaire: Drones for GIS Mapping

Friday, September 6th, 2019

The FAA estimates that there will be nearly half a million registered commercial use drones in the U.S. by 2022 (FAA 2018 – 2038 Aerospace Forecast).

Drones in construction

Drones, or UAVs or UAS, are being used in the GIS industry for such purposes as military surveillance, real estate, searching for hurricane activity, search and rescue missions, public health and safety, agriculture and in construction and countless other industries. In some cases, drones can provide greater resolution than satellite imagery. Their size and affordability makes them a valuable choice for scientists, power companies, surveyors, military actions and civilians and many others. They are also environmentally friendly and provide a low-cost option for gathering valuable data that can then be fed into a GIS.

Since drones can autonomously collect a vast range of data they are appealing to many use cases. Besides, they are light-weight and high performance. Satellite imagery has provided remote sensing data for mapping, but can often display low fidelity or limited visibility from cloud cover. High precision and accuracy can be achieved with aerial imagery, with planes equipped with high tech remote sensors. Photogrammetry, which makes use of overlapping photos to identify exact measurements between objects, is a useful way of gathering accurate models.

Esri User Conference 2019 Touts the Intelligent Nervous System

Friday, July 12th, 2019

The theme of Esri User Conference 2019 was “See What Others Can’t.” The idea is that with GIS, people have the power to see differently. This was the 39th Annual Users Meeting, and while the meeting attracts close to 12,000 attendees per year, Esri CEO and president Jack Dangermond said that the purpose remains the same as it was when they began meeting with users at a Montessori school many years ago.

Mapping Infectious Disease with Esri Workflows

Friday, June 21st, 2019

This week, GISCafe Voice spoke with Este Geraghty, MD, MS, MPH, GISP, Chief Medical Officer & Health Solutions Director, Esri. Formerly the Deputy Director of the Center for Health Statistics and Informatics with the California Department of Public Health, Dr. Geraghty led the state vital records and public health informatics programs. There she engaged in statewide initiatives in meaningful use, health information exchange, open data and interoperability.

Notre Dame Cathedral Viewed From Space and 3D Scans – Before and After

Thursday, May 2nd, 2019

The Notre Dame Cathedral has been well-documented both before and after a devastating fire destroyed its spire and roof on Monday, April 15, 2019. What we have going forward is extensive documentation in the forms of satellite imagery, aerial imagery, as well as 3D laser scans to help in the reconstruction of the Gothic cathedral.

Satellite Technology Used by UK Space Agency’s Forests 2020 Project to Monitor Tropical African Forests and Cocoa Industry

Thursday, April 25th, 2019

Supply chains in Africa have caused deforestation by illegal cocoa farming, damaging protected rainforests and creating damage to the very viable cocoa industry. Using satellite derived information from the UK Space Agency’s Forests 2020 Project, led by Ecometrica, the Ghana Forestry Commission has been supported in the development of a landscape-level map that separates cocoa from forestry, which is critical to measure how cocoa is driving deforestation. According to company materials, African Governments and the world’s cocoa companies look to UK Space Agency’s International Partnership Programme’s Forests 2020 to provide reliable and accurate maps that map forest cover change and differentiate cocoa farms from natural forests.
