Amazonian Mapping on Tasking Manager

Timeframe:

February 2024 - To be defined

Background

The team at the Open Mapping Hub - Latin America and the Caribbean (LAC Hub) is committed to highlighting the importance of social impact mapping in the vast Amazon region. Through initiatives deployed in Colombia, Ecuador, Brazil, and Peru, we aim to strengthen the capacity for prevention, emergency response, sustainable forest resource management, and community resilience. This effort focuses on detailed mapping of infrastructures, land uses, and critical environmental conditions, integrating them into the open and free cartographic database of OpenStreetMap (OSM). In this way, we facilitate access to this crucial information for local actors and experts, who can use it to understand risks and their impacts, as well as to implement coordinated strategies in their respective regions.

In close collaboration with the authorities responsible for risk management in Ecuador, Colombia, and Brazil, we have identified the most vulnerable areas during the first quarter of 2024, many of which are affected by extreme droughts related to the El Niño phenomenon in tropical forests. In response, we have launched mapping projects in the HOT Tasking Manager, with the aim of engaging the mapping community in the task of mapping these critical areas.

In commemoration of the International Day of the Amazon on February 11, 2024, we extend an open invitation to the mapping community to participate in these projects by exploring the tasks available on the Tasking Manager under the Amazonian Mapping campaign. This call to action seeks to mobilize efforts in support of vital initiatives for risk preparedness and response in this important region of the world.

Success Measurement

The #mapeo_amazonico tag will be used to track contributions (added buildings), but ultimately, success will be measured by the completion of all projects after being fully mapped and validated and successfully used for field data collection.

Mapping Instructions

Project-Specific Mapping Notes

Imagery: Bing has been defined as the primary data source; however, in areas with poor visibility and outdated imagery, it is recommended to use other sources like ESRI Imagery.

Some squares will already be partially or fully mapped, map more if necessary or correct existing mapping, or mark it as "Yes" in response to "Is this task completely mapped?" if it is already complete.

Existing mapping doesn't match imagery - This happens in some areas, when different imagery sources are used. If this occurs, ensure you are using the recommended imagery.

Alternative imagery is better - Sometimes, due to shadows, alignment, and other factors, it might be easier to trace features using other imagery. That's okay as long as you adjust any offset. When finished, leave a comment in the Tasking Manager when marking as done/finished mapping to say you used alternative imagery. Refer to LearnOSM for detailed instructions on handling imagery offset, or Aerial Imagery & Alignment for adjusting in the iD editor.

Buildings

Quick Tutorial: Buildings - https://www.youtube.com/watch?v=lSLe6rjtgi0

Please accurately outline all buildings you can find. The outline should be of the full size of the building even if it's partially covered by trees in the imagery.

Be careful not to include the shadow of the building in the building outline.

After labeling as a building, leave all 'Fields' empty: this information will be added later by local mappers.

After drawing the outline and labeling it as a building, use the 'Q' key in the iD web editor to "square" the corners.

Many buildings are very close together, but they actually don't touch each other, try to map them close to each other without letting them connect or share nodes with each other, roads, or residential area outlines. In the iD web editor, holding the "alt" key will prevent nodes from "snapping" to each other and connecting accidentally.

In the iD web editor, you'll only have the option to label new features as buildings, refer below for editing or adding other features. Only if you have personal knowledge of a building, add that information to the building, such as building type (hospital, school, gas station, etc.) or a name if it has one.

Roads and Trails

Do not map roads and trails.

General Mapping Notes

Be as accurate as possible - This takes a bit of practice, but closely following a road or building outline really makes a difference in the quality of the map data produced. Quality is more important than quantity when it comes to mapping. Zooming in helps.

Changeset comments: These are filled in with some default information, but you should always add what you mapped. For example, "added buildings and roads" or "added some watercourses." It's okay to "split" task squares - Sometimes, a task square will have a lot of detailed settlement

Results

At this moment, four projects have been published in the Amazon region, covering Ecuador, Brazil, and Colombia. One of these projects has been completed, while the other three are in progress, with a combined mapping progress of 90% and validation progress of 42%. In total, approximately:

  • 27,239 buildings have been mapped and 17,815 validated.
  • 63 roads mapped.
  • Approximately 63 km² of roads have been mapped, with 12 km validated.

Additionally, in MapSwipe, 15 of 22 projects have been completed, both located in Colombia, Brazil and Peru. Over 9126 contributors have participated in these projects, covering an area of over 59,249 km² in the search for buildings and 9,300 km² in the search for buildings and intervened forest areas.
