UN Big Data Regional Hub in Brazil is promoting a series of webinar about the production of climate change indicators. The next seminar will be held on February 19, at 11 am, and will discuss the artificil intelligence used in remote sensing.
Free registration is open to attend the webinar, click on https://hub.ibge.gov.br/index_port.htm. The event will be in English.
Speaker Raian Vargas Maretto will cover the challenges and potentialities of the use of artificial intelligence for the large scale analysis and interpretation of remote sensing data. The integration has revolutionized the observation and monitoring of environmental, urban and socioeconomic changes at national, continental and global levels. Some of the possibilities are real time monitoring of deforestation, detection of illegal mining activities and detailed analysis of urban areas.
Raian Vargas Maretto is a professor at the University of Twente, in the Netherlands. With a Master's degree in Remote Sensing and a PhD degree in Applied Computing from the Brazilian National Institute for Spatial Research (INPE), he is an expert in the application of deep learning, machine learning, data mining and other methods for the development of models based on artificial intelligence to automatically produce maps that combine geospatial data of multiple types.
Series on climate change indicators
The Big Data Regional Hub has been promoting a series of webinars to share experiences in the use of new sources of data and technologies aimed at the mitigation of climate changes. the topis approached include biodiversity, tourism sustainability and integration of geospatial information for the monitoring of land use. The sessions are presented in Spanish or English, with the participation of experts from Lation America and the Caribbean and from other Major Regions.
The series started last September with a webinar on climate changes and disasters. In October, the topic was new sources of data for the measurement of tourism sustainability. In November, warnings about hydrogeological disasters. The three events gathered 350 participants from 24 countries: Saudi Arabia, Argentina, Aruba, Belize, Bolivia, Brazil, Chile, Colombia, Costa Rica, Ecuador, El Salvador, Slovenia, Guatemala, Honduras, Jamaica, Mexico, Nicaragua, Panama, Paraguay, Peru, Dominican Republic, Trinidad and Tobago, Uruguay and Venezuela. Recordings are available on the Hub web site. Other monthly webinars are scheduled to take place until July 2025.
ENCE/IBGE coordinates UN Regional Hub for Big Data in Brazil
Resulting from a partnership between the IBGE and the UN Statistics Division, the UN Big Data Regional Hub in Brazil (https://hub.ibge.gov.br) was launched in November 2021 in the XI Statistical Conference of the Americas, carried out by the Economic Commission for Latin America and the Caribbean (ECLAC). The Hub is hosted in the National School of Statistical Sciences (ENCE), the IBGE´s academic arm that coordinates the efforts and contributions from different areas to support the activities of the Regional Hub.
The project aims at contributing to the advance in the use of Big Data to improve the production of official statistics, by sharing knowledge and developing innovative initiatives in Latin America and the Caribbean. In addition to Brazil, four other countries also integrate this initiative as headquarters of either global or regional hubs: United Arab Emirates, Indonesia, Rwanda and China.
