Correction to: Accuracy assessment of global food security-support analysis data (GFSAD) cropland extent maps produced at three different spatial resolutions (Remote sens. 2018, 10, 1800)

Abstract

This research paper [1] presented the accuracy assessment of the published cropland extent maps created by the GFSAD team and which are available for download from LPDAAC. It is very important to provide all the references for these maps. Therefore, after publication of this research paper [1], the authors wish to make the following additions to this paper. These additions are citations that were inadvertently left out of the original paper. Citations are added to the text and to figures and tables, where appropriate. In the abstract, the original sentence ‘An accuracy assessment and comparison of these three GFSAD cropland extent maps was performed to establish their quality and reliability for monitoring croplands both at global and regional scales’ should be updated as ‘An accuracy assessment and comparison of these three GFSAD cropland extent maps produced and published by different researchers was performed to establish their quality and reliability for monitoring croplands both at global and regional scales’. In the introduction section, the references from [5–7] should be updated to include [5–18]. In the Datasets section, Table 2 should be updated with an additional reference column presenting [5], [6–8], and [9–18] in each row (as shown below). In the Conclusions section, “The assessment report of the GFSAD30m cropland extent map is available online at https://lpdaac.usgs.gov [64]” must be updated at the end of the first paragraph.
