Detecting urban markets with satellite imagery: An application to India

Author: Ran Goldblatt 

 

We propose a methodology for defining urban markets based on builtup landcover classified from daytime satellite imagery. Compared to markets defined using minimum thresholds for nighttime light intensity, daytime imagery identify an order of magnitude more markets, capture more of India’s urban population, are more realistically jagged in shape, and reveal more variation in the spatial distribution of economic activity. We conclude that daytime satellite data are a promising source for the study of urban forms.

Satellite Imagery Offers View of Urban Markets In Real-Time

In the paper, “Detecting Urban Markets with Satellite Imagery: An Application to India,” Khandelwal and co-authors Kathryn Baragwanath-Vogel, Ran Goldblatt, and Gordon Hanson use nighttime and daytime satellite imagery to define urban markets based on economic activity. While daytime imagery isn’t typically used in economic studies, the researchers find that using nighttime imagery alone has the drawbacks of marking some cities appear larger than they actually are

Standardizing Remote Sensing Data Collection at FEMA

Author: Ran Goldblatt 

 

During a disastrous event such as a major hurricane, wildfire, catastrophic flooding or a destructive earthquake, first responders must quickly understand the magnitude and the nature of the event and its impacts upon citizens and communities. Remotely sensed data can be crucial for preliminary awareness about the scope of such a disaster. That is why the USA’s Federal Emergency Management Agency (FEMA) has implemented a tool called the Area of Interest (AOI) Tasker to automatically identify and prioritize areas that require collection of satellite and aerial imagery. It was used for the first time during the 2018 hurricane and wildfire seasons.

Assessing OpenStreetMap Completeness for Management of Natural Disaster by Means of Remote Sensing: A Case Study of Three Small Island States (Haiti, Dominica and St. Lucia)

Published in Remote Sensing

 

Large portions of the world, including countries exposed to natural disasters, remain incompletely mapped. Our study extends the existing literature by demonstrating how remotely sensed measurements could be leveraged to evaluate the completeness of the OSM database, especially in countries with high risk of natural disasters. Identifying areas that lack coverage of OSM features could help prioritize mapping efforts, especially in areas vulnerable to natural hazards and where current data gaps pose an obstacle to timely and evidence-based disaster risk management.

Geospatial data for research on economic development

Authors: Ran GoldblattBrad Bottoms, and Madeline Jones

 

It is estimated that in 2016 nearly 38 per cent of workers in the world’s least developed countries were living with their families below the poverty line (approximately $1.90 per person per day) (UN, 2017), often without access to schools, healthcare, electricity, safe water and other critical services. Yet, accurate data on the number of poor people and their living conditions are scarcely existent, especially in developing countries.

Big Data, Rising Tides: How Advances in Free Remote Sensing Technology Can Help Cities to Prepare for Climate Change

Published in GIM International

 

In view of the increased vulnerability of cities to climate and disaster risks, accurate and up-to-date geospatial data is fundamental for a more resilient urban planning approach. Publicly available geospatial datasets are increasingly becoming the foundation stone for more informed urban planning decision-making and better investment prioritization. Today, satellite data can help cities to better prepare for natural disasters such as urban flooding and make more informed investment decisions.

Innovations in satellite measurements for development

Combinatorial innovation is driving innovation in satellite-based economic measurements at unprecedented resolution, frequency and scale. Increasing availability of satellite data and rapid advancements in machine learning methods are enabling a better understanding into the fundamental forces shaping economic development.

Security Awareness Training as a Service

“The root cause of every successful cyber breach or incident is human error. Systems and software only function in the way they are configured and deployed. The glaring fault in every breach scenario is with the end-users decision making behind those systems, whether supporting them or using them … No matter the size of the organization, the common threat from inside is user decision making. As technology advances, so do security breaches; to diminish threats cultivated training, awareness, information sharing, and communication are integral in building a successful defense. “

Getting Ready for Disaster Events with Remote Sensing: Predicting OpenStreetMap Completeness in Risk Areas

Author: Ran Goldblatt, Nicholas Jones, Jenny Mannix
Published in GIM International

 

“In view of the increased frequency and severity of natural disasters, timely information related to the distribution of vulnerable populations and critical infrastructure is key for effective disaster relief. OpenStreetMap shows great potential to support humanitarian mapping tasks and has provided vital information in many past major disasters. Publicly available remotely sensed measurements can be utilized to identify areas that have not yet been fully mapped and help guide and prioritize future mapping efforts in preparation for future disasters. “
