dc.description.abstract |
A global reference data set on cropland was collected through a crowdsourcing campaign using the Geo-
Wiki crowdsourcing tool. The campaign lasted three weeks, with over 80 participants from around the
world reviewing almost 36,000 sample units, focussing on cropland identification. For quality assessment
purposes, two additional data sets are provided. The first is a control set of 1,793 sample locations validated
by students trained in satellite image interpretation. This data set was used to assess the quality of the
crowd as the campaign progressed. The second data set contains 60 expert validations for additional
evaluation of the quality of the contributions. All data sets are split into two parts: the first part shows all
areas classified as cropland and the second part shows cropland average per location and user. After further
processing, the data presented here might be suitable to validate and compare medium and high resolution
cropland maps generated using remote sensing. These could also be used to train classification algorithms
for developing new maps of land cover and cropland extent. |
