ArticleEarth Map: A Novel Tool for Fast Performance of Advanced Land Monitoring and Climate Assessment 2023
Also available in:
No results found.Earth Map (https://earthmap.org/) is an innovative and free application developed by the Food and Agriculture Organization of the United Nations that was designed in the framework of the Food and Agriculture Organization of the United Nations–Google partnership and facilitates the visualization, processing, and analysis of land and climate data. Earth Map makes petabytes of multitemporal, multiscale, multiparametric, and quasi-real-time satellite imagery and geospatial datasets available to any user thanks to the power of Google Earth Engine (https://earthengine.google.com/) and a point-and-click graphical user interface. These are further complemented with more planetary-scale analytical capabilities so that global and local changes and trends on Earth’s surface can be easily detected, quantified, and visualized. It does not require users to master coding techniques, thereby avoiding bottlenecks in terms of technical capacities of nonexpert users. It ultimately paves the way for countries, research institutes, farmers, and members of the general public to access critical knowledge to develop science-based policy interventions, leverage investments, and sustain livelihoods. We provide a full overview of Earth Map’s software architecture, design, features, and datasets. To illustrate the possible applications of the tool, different examples are presented including a few case studies that show how quick historical analysis of environmental and climate parameters can be performed and research questions answered. The examples demonstrate that Earth Map is a comprehensive and user-friendly tool for land monitoring and climate assessment and that it has the potential to be used to assess land use, land use change, climate change impacts, and natural disasters. -
No Thumbnail AvailableBook (stand-alone)Preparation of Land Cover Database of Bulgaria through Remote Sensing and GIS 2001
Also available in:
No results found.Land cover maps constitute a necessary tool for development planning and management of the territory. Furthermore, land cover maps depicting the current reality are a must in countries where, due to political changes, rapid dynamic phenomena have taken place, resulting in a complete restructuring of the agricultural and other sectors, as in the case of Bulgaria. The scale of such maps should be large enough to provide detailed information, however it should allow for regional assessment, st atistics and subsequent planning. The 1:50 000 scale is the most suited for this exercise. The FAO project TCP/BUL/8922 “Strengthening Capacity in Agricultural Development through Remote Sensing and GIS” has produced 14 land cover maps at 1:50 000 scale for selected test areas of the country, covering 5 600 sq km. These maps were prepared using Landsat satellite data, acquired in 1998 and 1999 as the main data source and thus represent the land cover existing at that time. The land cover cl assification was performed using the FAO Land Cover Classification System (LCCS). To each mapped unit (polygon), soil type and erosion features were linked as attributes into the GIS system. This created a comprehensive database, which is unique in Bulgaria. The database provides very useful information for agriculture, forestry and urban development planning, for environment protection and for many other applications. The data collected in the database provide the possibility for different kinds of spatial analysis, which is necessary in land management. For an area of particular interest, IKONOS very high resolution satellite data were used to produce an assessment of the state of vineyards, the updating of the linear features of a large scale topographical map and other applications. The methodology and applications reported in this study have been tested and refined under operative conditions in the framework of the project’s activities. -
Book (stand-alone)Leveraging space technology for agricultural development and food security 2025
Also available in:
No results found.The publication “Leveraging Space Technology for Agricultural Development and Food Security” was produced by FAO and UNOOSA in response to the ongoing dialogue within the Committee on the Peaceful Uses of Outer Space (COPUOS). It underscores the transformative potential of space technologies in enhancing agricultural productivity and ensuring food security amid global challenges. The document advocates for collaborative approaches that integrate advanced technologies while addressing associated risks, particularly space debris. It is structured into three segments: the upstream segment focuses on developing vital space infrastructure, highlighting pivotal Earth observation missions like Landsat and Copernicus, which provide crucial data for precision farming; the midstream segment addresses the importance of data management and spatial data infrastructure (SDI), emphasizing frameworks like the UN-IGIF for improving data accessibility and quality; finally, the downstream segment discusses practical applications of satellite data in agriculture monitoring and management, showcasing platforms such as the FAO Hand-in-Hand Geospatial Platform to facilitate information exchange. This publication aims to foster partnerships between the agricultural and space sectors, further promoting sustainable development in alignment with the 2030 Agenda. This publication serves as a vital resource for stakeholders looking to harness space technologies for sustainable agricultural practices and enhanced food security globally.
