NICFI Basemaps to detect deforestation in the Rawa Singkil Wildlife Sanctuary

Deforestation in the Rawa Singkil Wildlife Sanctuary conservation area has increased yearly since 2019. From monitoring results using satellite data and supported by Glad Alert-GFW alert data, HaKa researchers found that the Rawa Singkil SM area had undergone a relatively significant shift from forest to non-forest this year. Lukmanul Hakim, director of HAKA's Geographic Information System, mentioned that deforestation in the first seven months of 2022 is already more significant than the total amount in the last three years. The specialist said that the NICFI Basemaps help detects the monthly deforestation in the Leuser Ecosystem in Aceh. According to their findings, the Wildlife Sanctuary lost 338 hectares of forest in 2021 (165 hectares), 2020 (43 hectares) and 2019 (28 hectares). The specialist also mentioned that this incident is not uncommon and should be monitored. HaKa hold a press conference to involve local authorities in the search for a better response to these deforestatio

NICFI basemaps on detecting illegal mining in Brazil

An unprecedented study of clandestine airstrips in the Brazilian Amazon rainforest, conducted in a partnership between The New York Times, The Intercept, the Pulitzer Center and Earthrise Media, gathered data on illegal mining 🎉The team compiled the possible locations of illegal airstrips by gathering data from Open Street Maps, the Socio-Environmental Institute and Hutukara. Then, by cross-referencing the geographic coordinates of the runways with mining deforestation alerts from Amazon Mining Watch, they found that 1,269 unregistered airstrips were still in active use in the last year and documented signs of mining nearby, such as cleared forest areas and mining pools. The team used satellite imagery 🛰 and geospatial analysis 🗺 to locate the airstrips and interconnect them with illegal mining, benefiting from NICFI data. In addition, they determined that hundreds of the airstrips in mining areas are located within indigenous and protected lands, where any form of mining is against

Which Method is Used to Create the Planet & NICFI Tropical Monitoring Basemaps

This question was originally asked March 10, 2022 05:57 by user Maurice Kalthof. Hi,I was wondering how the basemaps, especially the bi-annual basemaps up untill september 2020, are compiled. Are the pixels/images selected based on a quality assesment, or is the median / mean used? If I know this, I can make a better assesment on what period / situation the basemaps represent.

NICFI Satellite Data in Payments for Environmental Services in Mato Grosso, Brazil

The Amazon Environmental Research Institute (IPAM) uses NICFI satellite data in the CONSERV initiative in the state of Mato Grosso, Brazil. This initiative is based on Payments for Ecosystem Services (PES) to farmers who register in their program and conserve native forests on their properties. NICFI data is essential for monitoring native vegetation on members' farms so members can receive their payment for preserving the natural ecosystem. IPAM also uses NICFI data to conduct complementary assessments of databases on deforestation, degradation, fire, and permits to remove native vegetation from farms. Additionally, they use the imagery to obtain temporal patterns of Vegetation Indexes to map specific land uses for single plots on different farms. Planet image from October 4, 2021 used for the monitoring of a farm in the State of Mate Grosso, in comparison with the mosaic from October 2020. Retrieved from: IPAM, 2021.

This is how the damage of the desert locust outbreak in Ethiopia is detected using NICFI basemaps!

Ethiopia experienced the worst desert locust outbreak in 2020, which increased food insecurity. This year, Woubet G. Alemu and Christopher S. R. Neigh published their article titled "Desert Locust Cropland Damage Differentiated from Drought with Multi-Source Remote Sensing in Ethiopia" in the Remote Sensing Journal (MDPI). Their research targets to estimate desert locusts' paths and breeding sites using satellite remote sensing and climate factors. The team used multiple remote sensing sources to conduct this study and analyze the damage of desert locusts in the region. One of the sources they benefited from is monthly PlanetScope Basemaps, provided freely by the NICFI Satellite Data Program. Additionally, to differentiate between cropland damage from desert locusts and the usual drought conditions of the region, the researchers made a detailed remote sensing-based analysis of drought in Ethiopia. They underline that drought has been a common phenomenon in Ethiopia and has devastati

Landslide Monitoring in Ecuador

This week’s user story is about monitoring a landslide area in Ecuador. In February 2020, the San Rafael waterfall collapsed, and regressive erosion started around the Coca River, which put the environment and indigenous communities in the surrounding area in danger. The study area is located in Northeast Ecuador, at the River Coca, between the San Rafael Waterfall and the Coca Codo Sinclair Hydropower Dam and close to the volcano Reventador. They analyzed the erosion event with Sentinel-1 SAR data and included in the validation the PS Tropical Normalized Analytic Biannual Archive basemap from June to November 2019 and PlanetScope Imagery between 2020-02-14 and 2020-03-2021. The researchers emphasized that remote sensing and GIS are crucial for assessing and analyzing landslide areas and particularly significant for better regional risk management.Click here to read the article and learn more about the research.

Basemap viewer and GEE's tfrecord image different

We notice a significant difference between some images that Planet shows us on its Planet-NICFI Basemap Viewer and those extracted in TFRecord format. Here is a guided example of what we notice:There is a shp and a geojson (id_27954006.zip) of a 540x540 meters grid on this link: drive.google.com/drive/folders/1jv-oFoLkJZLCJieXIpULBYxqsPg6wl32?usp=sharingThis is what this geometry looks like in ‘planet_medres_normalized_analytic_2021-10_mosaic’ in Basemap Viewer: Basemap View of the id_27954006.geojson in 2021-10 normalized mosaicWe extract the NICFI-Planet geometry of this shp into TFRecord files using Planet integration with Google Earth Engine. Tropical Americas Image Collections are filtered as in the developer’s example using python. We use ee.Filter.date(‘2021-10-01’, ‘2021-10-31’) to get the same October mosaic basemap than before.This process results in a TFRecord file (id27954006_1.tfrecord.gz) with bands data from Planet Basemap (R, G, B).
