Creating a Training Dataset

Summary

• We must collaboratively generate a sample (training) dataset for the area, around 10-20% of total digitized features.
• With this training data we can run fAIr in the next step to generate the remaining features.
• We have two options:
  • uMap
  • Modified Tasking Manager :::

Option 1: UMap

• Choose a uMap instance to use 1 2
• Create a new project, add the TMS URL from the previous step (OpenAerialMap).
• Send the project link to digitizers.
• Map collaboratively, with real-time updates.
• Export the final GeoJSON.

Option 2: Tasking Manager

• The TMS URL from OAM can be used as a base layer in Tasking Manager.
• The instance of Tasking Manager available at https://train.hotosm.org is not linked to standard OpenStreetMap (OSM), but instead to a ‘sandbox’ version.
• Create a new project, add the TMS URL from the previous step (OpenAerialMap).
• Map the area collaboratively.
• Output the data as GeoJSON.
