Remote Sensing Field Work Tools

In remote sensing, designing a field campaign to collect ground-truth data can be a challenging task. We need to collect representative samples while accounting for issues such as budget constraints and limited accessibility created by e.g. poor infrastructure. As suggested by Olofsson et al. (2014) , this demands the establishment of best-practices to collect ground-truth data that avoid the waste of time and funds. 'fieldRS' addresses this issue by helping scientists and practitioners design field campaigns through the identification of priority sampling sites, the extraction of potential sampling plots and the conversion of plots into consistent training and validation samples that can be used in e.g. land cover classification.

R package to support Remote Sensing oriented field work. It was developed at the University of W├╝rzburg, Germany, as part of the project Research Network Water in Central Asia (CAWa) funded by the German Federal Foreign Office. It is part of the German Water Initiative for Central Asia (the so-called Berlin process), which the German Federal Foreign Office launched on the 1st of April of 2008 to support peaceful, sustainable and mutually beneficial management of transboundary water resources in Central Asia. `fieldRS` was designed to ease the collection and management of ground truth data. It provides tools that help select sampling sites, correct and pre-process training data and preview classification results in order to identify potentially incorrect samples.
