NASA’s Applied Remote Sensing Training Program (ARSET) has opened a new open, online webinar series: Earth Observations for Humanitarian Applications. Refugees, internally displaced people (IDPs), and other displaced populations are made more vulnerable to climate change impacts due to their socio-political marginalization. This three-part, intermediate training presents concrete strategies for mapping localized climate conditions with risks faced by refugee and IDP communities around the world.

The training will focus on flood risk assessments and specific challenges for assessing flood risk in refugee and IDP camps; gauging long-term heat stress in refugee camps and the challenges with decision making surrounding heat risk; and monitoring drought effects on agricultural landscapes in refugee settings using Earth observations (EO) to explore the correlations between anomalies in crop productivity and weather-based factors

NASA’s Applied Remote Sensing Training Program (ARSET) has opened a new open, online webinar series: Assessing the Impacts of Fires on Watershed Health. This advanced-level, three-part training will focus on using remote sensing observations for monitoring post-fire impacts on watershed health. Specifically, this training will highlight uses of NASA Earth observations (EO) for pre-fire land cover mapping, watershed delineation and stream mapping, post-fire burn severity mapping, and pre- and post-fire riverine and freshwater water quality.

NASA’s Applied Remote Sensing Training Program (ARSET) has opened a new online introductory webinar series: Fundamentals of Machine Learning for Earth Science. This three-part training, presented in English and Spanish, is open to the public and will provide attendees an overview of machine learning in regards to Earth Science, and how to apply these algorithms and techniques to remote sensing data in a meaningful way. Attendees will also be provided with end-to-end case study examples for generating a simple random forest model for land cover classification from optical remote sensing. We will also present additional case studies to apply the presented workflows using additional NASA data.

NASA’s Applied Remote Sensing Training Program (ARSET) has opened a new online advanced webinar series: Crop Mapping using Synthetic Aperture Radar (SAR) and Optical Remote Sensing. This three-part training, presented in English and Spanish, is open to the public and builds on previous ARSET agricultural trainings. Here we present more advanced radar remote sensing techniques using polarimetry and a canopy structure dynamic model to monitor crop growth. The training will also cover methods that use machine learning methods to classify crop type using a time series of Sentinel-1 & Sentinel-2 imagery. This series will include practical exercises using the Sentinel Application Platform (SNAP) and Python code written in Python Jupyter Notebooks, a web-based interactive development environment for scientific computing and machine learning.

Aumenta el impulso en torno a las iniciativas internacionales de monitoreo de la tierra, junto con una demanda sin precedentes de datos e información sobre la tierra gratuitos, accesibles y utilizables. El sector de la tierra debe encontrar la manera de aprovechar las oportunidades que ofrecen las innovaciones en materia de datos abiertos, negociando al mismo tiempo un entorno de datos en rápida evolución. 

El Land Portal y la Carta de Datos Abiertos han estado trabajando con el Gobierno de Senegal para abrir los datos sobre la tierra, siguiendo las orientaciones establecidas en la Guía Open Up para la Gobernanza de la Tierra. La Guía Open Up es una guía práctica para los gobiernos que desean recopilar, publicar y utilizar mejor los datos sobre la tierra para el bien público. Como Fase 1 de este proyecto, el equipo ha publicado el Informe sobre el Estado de la Información de la Tierra en Senegal (SOLI por sus siglas en inglés). Los informes SOLI son análisis basados en la investigación del estado actual de los datos sobre la tierra que evalúan la información disponible sobre la tierra en relación con las normas de datos abiertos. 

En el seminario web:

• Se compartirán los últimos resultados del proyecto piloto de aplicación de la Guía Open Up en Senegal y las conclusiones del informe SOLI Senegal. 
• Se plantearán y debatirán preguntas sobre el interés y la madurez de los datos abiertos en Senegal en relación con la tierra. 
• Escuchar las perspectivas del gobierno de Senegal (ANAT, PROCASEF), los donantes (GIZ, Banco Mundial), los miembros de la comunidad local, utilizando estudios de casos específicos sobre los datos y las iniciativas de la tierra

This two-part webinar series will provide an overview of resources for choosing climate projection sets for mitigation, adaptation, and risk management applications.

Recent studies have shown that globally, riverine and coastal floods are increasing in intensity and duration. In addition, the number of people living in flood-prone areas has increased substantially during the last two decades.

De noche, las imágenes satelitales capturan una señal únicamente humana – la iluminación artificial. La teledetección de luces nocturnas viene a ser una nueva fuente de datos para mejorar nuestro entendimiento de la interacción entre la sociedad y el medio ambiente.
