Calibration and validation data for infratructure mapping, Greenland

This dataset contains geographical features representing selected infrastructures (houses, roads, airfields, pipelines etc.) in some West Greenland towns and settlements. Each feature has attributes listing relevant classificiers, such as: - the type of infrastructure (residential building, road, pipeline, etc.) - the shape of the feature (flat, sloped, pitched, domed, barrel-shaped) - the type of surface material (wood, concrete, asphalt, etc.) - the background setting (bedrock, sediments, sea, etc.) - it current status as actively used or inactive infrastructure All feature locations and attributes have been validated either by on-site inspection, or by Google Street View imagery (validation method indicated in feature attributes). Photos are provided for most of the features that were field validated.
