Dear readers,
We're glad to share with you the January 2020 UN-SPIDER Monthly Updates, and would like to make you aware of our latest Recommended Practice, which explains how to map floods and assess related damage using Sentinel-1 data and Google Earth Engine. This step-by-step procedure provides a useful outline of floods, while overlaying the flood extent with land use and population information to instantly output statistics such as area of cropland and number of population within the damaged areas. It aims to be a simple and quick tool for users of any experience level to obtain an overview of a flood event.
The Recommended Practice can be accessed on the UN-SPIDER Knowledge Portal: www.un-spider.org/advisory-support/recommended-practices/recommended-practice-google-earth-engine-flood-mapping
Below the updates, you'll also find an events calendar with upcoming conferences, workshops and seminars organized by the community.
Enjoy the read!
