How mapmakers help indigenous people defend their lands
▻https://www.nationalgeographic.com/culture-exploration/2018/10/indigenous-cultures-mapping-projects-reclaim-lands-columbusOne early project in the 1990s focused on the remote Darién region of Panama. Official maps of the area contained little detail—the persistent cloud cover and dense rainforest canopy were impenetrable to the satellite imagery and aerial photos that government cartographers used to make their maps. But to the three main indigenous groups in the region, Emberá, the Wounaan, and the Guna, the land was filled with landmarks.
The organization’s approach was simple: ask indigenous people to draw detailed maps of their lands, and then get professional cartographers to incorporate this information into modern, geographically accurate maps.
To map the Darién, indigenous leaders selected men from communities in the region to act as surveyors. The surveyors then set out by bus, by canoe, or on foot, armed with pencils, pens, and blank sheets of manila paper to sketch the local waterways and other landmarks. In collaboration with villagers and their leaders they carefully drew maps that included things of importance to their communities that wouldn’t typically appear on government maps, like hunting and fishing grounds, or places where firewood, fruit, or medicine were gathered. They often chose to leave out cemeteries and sacred sites, preferring to keep that knowledge within their communities. The quality of these maps varies considerably, but the best of them are works of art, Chapin says (see below).

Bike Trip : 5000 km à vélo pour cartographier l’Amérique du Sud
▻https://www.trekmag.com/news-bike-trip-5000-km-velo-cartographier-amerique-sudAlban Vivert est parti de Bogota début mai, pour une itinérance sur deux roues à travers la #Colombie, l’#Équateur et le #Pérou. Un périple musclé, avec 5 130 km et 95 000 mètres de dénivelé positif. Durant quatre mois, il sillonne les routes et les petits chemins, passe des cols à plus de 4 000 m d’altitude et pédale sous tous les temps. Accroché en permanence à son vélo, un GPS qui enregistre sa trace. Car au-delà du défi sportif, l’idée d’Alban était "d’apporter quelque chose au pays visité".
L’utilisation du #vélo, véhicule passe partout, a permis de cartographier des routes inexistantes sur #Google_Maps et de nourrir une base de données de 110 000 photos des régions traversées, toutes géolocalisées et ajoutées le jour même sur #Mapillary ou #OpenStreetMap. « Au total, j’ai cartographié plus de 10 000 objets, du chemin de terre au café du coin en passant par les maisons ou les administrations », raconte le voyageur. [...]
Dans chaque pays traversé, le projet #Nomad_Maps s’est appuyé sur les communautés « OpenStreet » locales. Des contributeurs à la cartographie collaborative qui ont géolocalisé leur maison, leur quartier ou lancé des projets. « Le but final, c’est ce qu’on appelle le ’carto empowerment’, c’est à dire se remettre à exister par l’information géographique. À Bogota, j’ai par exemple travaillé avec une association qui agissait dans un quartier délaissé. En le cartographiant de manière exhaustive, les habitants pouvaient ainsi montrer qu’ils existaient. Il rendaient ainsi leur quartier attractif au niveau touristique ou pour les investisseurs pour ne pas qu’il tombe en désuétude et dans l’oubli des politiques publiques », raconte Alban.-
Oh, je l’ai rencontré cette semaine à Buenos Aires :)
Il a de très bons mollets.Il insistait sur la difficulté d’envoyer les milliers de photos à Mapillary dans des endroits où il y avait très peu de connectivité (résolu en accumulant les cartes SD).
Il retourne bientôt à Lyon, si vous avez la possibilité, contactez-le.

Classifying #drivers of #global_forest_loss | Science
▻http://science.sciencemag.org/content/361/6407/1108/tab-figures-data#Mapping global #deforestation patterns
Forest loss is being driven by various factors, including commodity production, forestry, agriculture, wildfire, and urbanization. Curtis et al. used high-resolution Google Earth imagery to map and classify global forest loss since 2001. Just over a quarter of global forest loss is due to deforestation through permanent land use change for the production of commodities, including beef, soy, palm oil, and wood fiber. Despite regional differences and efforts by governments, conservationists, and corporations to stem the losses, the overall rate of commodity-driven deforestation has not declined since 2001.Abstract
Global maps of forest loss depict the scale and magnitude of forest disturbance, yet companies, governments, and nongovernmental organizations need to distinguish permanent conversion (i.e., deforestation) from temporary loss from forestry or wildfire. Using satellite imagery, we developed a forest loss classification model to determine a spatial attribution of forest disturbance to the dominant drivers of land cover and land use change over the period 2001 to 2015. Our results indicate that 27% of global forest loss can be attributed to deforestation through permanent land use change for commodity production. The remaining areas maintained the same land use over 15 years; in those areas, loss was attributed to forestry (26%), shifting agriculture (24%), and wildfire (23%). Despite corporate commitments, the rate of commodity-driven deforestation has not declined. To end deforestation, companies must eliminate 5 million hectares of conversion from supply chains each year.-

Land change is a cause and consequence of global environmental change1,2. Changes in land use and land cover considerably alter the Earth’s energy balance and biogeochemical cycles, which contributes to climate change and—in turn—affects land surface properties and the provision of ecosystem services1,2,3,4. However, quantification of global land change is lacking. Here we analyse 35 years’ worth of satellite data and provide a comprehensive record of global land-change dynamics during the period 1982–2016. We show that—contrary to the prevailing view that forest area has declined globally5—tree cover has increased by 2.24 million km2 (+7.1% relative to the 1982 level). This overall net gain is the result of a net loss in the tropics being outweighed by a net gain in the extratropics. Global bare ground cover has decreased by 1.16 million km2 (−3.1%), most notably in agricultural regions in Asia. Of all land changes, 60% are associated with direct human activities and 40% with indirect drivers such as climate change. Land-use change exhibits regional dominance, including tropical deforestation and agricultural expansion, temperate reforestation or afforestation, cropland intensification and urbanization. Consistently across all climate domains, montane systems have gained tree cover and many arid and semi-arid ecosystems have lost vegetation cover. The mapped land changes and the driver attributions reflect a human-dominated Earth system. The dataset we developed may be used to improve the modelling of land-use changes, biogeochemical cycles and vegetation–climate interactions to advance our understanding of global environmental change1,2,3,4,6.

Building the Roman Empire #Vector #Tile #Map | Pelagios Commons
▻http://commons.pelagios.org/2017/11/building-the-roman-empire-vector-tile-mapIn our previous article, we wrote about the difference between raster tiles and vector tiles, ▻http://commons.pelagios.org/2017/09/rdg-update-the-roman-empire-vector-map-project. Now, we will be able to study the outcome. The technicalities of the process will be discussed, and the result as of now can be studied here ▻https://klokantech.github.io/roman-empire/#3.97/45.49/6.47. The section “Display the vector tiles with style” goes over the functionalities of the map.
The input layers for the map have been extracted from the SQL-database of DARE, ▻https://dare.ht.lu.se with a subset of the attributes, that is, places, roads, fortifications and provinces. The files can be edited in a desktop GIS application such as QGIS. Since we are publishing the data on Github, only data with an open license has been included in the project. They are all vector layers (point and line geometries) and have been converted to GeoJSON format in WGS 84 projection. They can be explored from the website of the project at Github, ▻https://github.com/klokantech/roman-empire in the data directory and previewed on a map. Among the input files are also the icons (in SVG format) that depict places of different types, and server scripts.

Data vandal changes name of New York City to “Jewtropolis” across multiple apps [Updated] | Ars Technica
▻https://arstechnica.com/information-technology/2018/08/data-vandal-changes-name-of-new-york-city-to-jewtropolis-across-multiplUpdate, 12:20 pm: In a prepared statement sent to press, a Mapbox spokesperson said that Mapbox has “a zero tolerance policy against hate speech and any malicious edits to our maps.” The label change was deleted within an hour. “The malicious edit was made by a source that attempted several other hateful edits,” the spokesperson said. “Our security team has confirmed no additional attempts were successful.”
Mapbox data comes from more than 130 sources, and the Mapbox spokesperson said that the company has "a strong double validation monitoring system." A machine learning system flagged the change for review; this change was one of more than 70,000 that are flagged on a daily basis, according to the company. “While our AI immediately flagged this,” the spokesperson said, “in the manual part of the review process a human error led to this incident. Security experts are working to determine the exact origin of this malicious hate speech. We apologize to customers and users who were exposed to this disgusting attack.”

The Aviationist » F-35 Stealth Aircraft Goes “Live” On Flight Tracking Websites As It Flies Mission Over Israel
▻https://theaviationist.com/2018/07/24/f-35-stealth-aircraft-goes-live-on-flight-tracking-websites-as-it-flAn F-35, most probably one of the Adir jets recently delivered to the Israeli Air Force, appears on Flightradar24.com: deliberate action or just a case of bad OPSEC?
On Jul. 23, an F-35 went fully visible on popular flight tracking website Flightradar24.com as it performed a mission out of Nevatim airbase. The aircraft could be monitored for about 1 hour as it went “feet wet” (over the sea) north of Gaza then flew northbound to operate near Haifa.
[…]
As for the reasons why the aircraft could be tracked online, there are various theories. The first one is that it was a deliberate action: considered the F-35 went “live” few hours Israel made first operational use of David’s Sling missile defense system against two SS-21 Syrian ballistic missiles, there is someone who believes the mission was part of a PSYOPS aimed at threatening Israel’s enemies (Syria in particular). Our readers will probably remember the weird, most probably bogus claim of an IAF F-35 mission into the Iranian airspace originally reported by the Al-Jarida newspaper, a Kuwaiti outlet often used to deliver Israeli propaganda/PSYOPS messages.However the Israeli Air Force has already made public the fact that the F-35 has been used in air strikes in the Middle East (Syria and another unspecified “front”) lately. On May 23, the Israeli Air Force Commander, Maj. Gen. Amikam Norkin said during a IAF conference attended by 20 commander of air forces from around the world: “The Adir planes are already operational and flying in operational missions. We are the first in the world to use the F-35 in operational activity”. He also showed a photograph of an “Adir” flying at high altitude off Beirut (with radar reflectors, hence not in “stealthy mode”). In other words, there’s probably no need to remind Syria or Iran that the Israeli Air Force has the F-35 since they are already using it in combat.
For this reason, there is also someone who believes that the first appearance of an Israeli Adir on Flightradar24 may have been a simple mistake: the Mode-S transponder was not turned off. A case of OPSEC fail in one of the most secretive air arms in the world.
Indeed, transponders are usually turned off during real operations as well as when conducting missions that need to remain invisible (at least to public flight tracking websites and commercial off the shelf receivers). Unless the transponder is turned on for a specific purpose: to let the world know they are there. In fact, as reported several times here, it’s difficult to say whether some aircraft that can be tracked online broadcast their position for everyone to see by accident or on purpose: increasingly, RC-135s and other strategic ISR platforms, including the Global Hawks, operate over highly sensitive regions, such as Ukraine or the Korean Peninsula, with the ADS-B and Mode-S turned on, so that even commercial off the shelf receivers (or public tracking websites) can monitor them. Is it a way to show the flag? Or just a mistake?
