In the forests of the Amazon, the Congo Basin and Southeast Asia, fire can mean the advance of deforestation and most part of the fires are caused by humans in order to “clear the ground” for agricultural production or new pastures.</p> <p>In this tutorial, we will demonstrate how you can create your own map of fire hotspots and update it in real time. This is made possible through the availability of data from satellites orbiting the Earth. These datasets are updated daily by NASA – the US space agency – and can be viewed with the help of two digital map-making tools – Google My Maps and Carto.</p> <h1 class="summary-item" id="finding-firedata"><a href="#finding-firedata">Finding FireData</a></h1> <p>The site <a href="https://earthdata.nasa.gov/" target="_blank">Earth Data</a> from NASA is one of the most complete repositories of  freely available satellite data. Through the NASA <a href="https://earthdata.nasa.gov/earth-observation-data/near-real-time/firms%20%20%C2%A0" target="_blank">FIRMS project (Fire Information Resource Management System)</a> you can access real-time data in multiple file formats and also order time series to download. In this tutorial, we’ll work with the <a href="https://geojournalism.org/tracks/csv/" target="_blank">CSV format</a>, the table separated by commas.</p> <p><a href="https://earthdata.nasa.gov/earth-observation-data/near-real-time/firms/active-fire-data" target="_blank"><img alt="Active Fire Data site" class="aligncenter wp-image-1523" decoding="async" fetchpriority="high" height="326" sizes="(max-width: 640px) 100vw, 640px" src="https://geojournalism.org/wp-content/uploads/2016/03/Active-Fire-Data-site-1024x521.jpg" srcset="https://geojournalism.org/wp-content/uploads/2016/03/Active-Fire-Data-site-1024x521.jpg 1024w, https://geojournalism.org/wp-content/uploads/2016/03/Active-Fire-Data-site-300x153.jpg 300w, https://geojournalism.org/wp-content/uploads/2016/03/Active-Fire-Data-site.jpg 1898w" width="640"/></a></p> <p style="text-align: center;"><em>This is the page of Active Fire Data on NASA’s Earth Data website</em></p> <p>The first step after accessing the FIRMS page is to continue to <a href="https://earthdata.nasa.gov/earth-observation-data/near-real-time/firms/active-fire-data" target="_blank">Active Fire Data repository</a>. There are two databases that can be used. One of them, the <a href="https://modis.gsfc.nasa.gov/" target="_blank">MODIS sensor</a>, although lower resolution (1 km), has the longest historical series because the sensor has been operating for years in the Terra and Aqua satellites. More recently, the  higher resolution (375 m) <a href="https://jointmission.gsfc.nasa.gov/viirs.html" target="_blank">VIIRS sensor</a>, has been generating large amounts of fire data. For this example, we will use the text file (CSV) of the MODIS sensor for the last 24 hours in Central Africa.</p> <p><img alt="Active Fire Data selection" class="aligncenter wp-image-1522" decoding="async" height="352" sizes="(max-width: 640px) 100vw, 640px" src="https://geojournalism.org/wp-content/uploads/2016/03/Active-Fire-Data-selection-1024x563.jpg" srcset="https://geojournalism.org/wp-content/uploads/2016/03/Active-Fire-Data-selection-1024x563.jpg 1024w, https://geojournalism.org/wp-content/uploads/2016/03/Active-Fire-Data-selection-300x165.jpg 300w, https://geojournalism.org/wp-content/uploads/2016/03/Active-Fire-Data-selection.jpg 1544w" width="640"/></p> <p>Once selected, the file can be saved as a CSV or its link may be used to update spreadsheets in real time.
