Remarks to authors' answers to previous comments
2017
The issue concerning the CAPTCHA plug in is not really about its definition, but about HOW it will be used as a "volunteered contribution". How, for example, random images of a deforested area chosen for security reasons will contribute to the monitoring of land use? Additionally, despite the content of the outline, it makes more sense that it comes at the end of the introduction, providing readers with an initial and general idea of what will follow. The current topic 1.1 could come together with the description of data sources used and papers selection (to be included), as part of a methodology section.
