This research project studies an area in the border region of Poland and Ukraine. With the fall of the Iron Curtain the region experienced drastic changes in political and socio- economic structures. Large farmland areas become abandoned and gradual processes of forest succession take place on the abandoned land. Reliable statistics are not available, however, remote sensing systems have the potential to provide spatially distributed and temporally frequent data on land cover and its environmental state. Thus, remote sensing based mapping offers great opportunities to map these phenomena and ultimately to better understand patterns, processes and underlying causes. Existing studies are based on multispectral imagery, abandonment maps, however, are difficult to obtain due to spectral ambiguities, phenological variability and limited data availability. SAR data can overcome these problems and different remote sensing studies demonstrated the potential of multisensor imagery. The aim of the project is the development of adequate strategies to monitor farmland abandonment, using multitemporal SAR and multispectral remote sensing data. Finally enhanced maps should be provided, which enable more detailed analysis of the gradual process of land cover transitions.

该研究项目研究了波兰和乌克兰边境地区的一个地区。随着铁幕的倒塌，该地区的政治和社会经济结构发生了巨大变化。大面积的农田被遗弃，在被遗弃的土地上发生了逐渐的森林演替过程。虽然没有可靠的统计数据，但是遥感系统有可能提供关于土地覆盖及其环境状况的空间分布和时间频繁的数据。因此，基于遥感的制图为绘制这些现象并最终更好地了解模式、过程和根本原因提供了很大的机会。现有的研究基于多光谱图像，然而，由于光谱模糊、物候变化和数据可用性有限，难以获得废弃地图。SAR数据可以克服这些问题，不同的遥感研究表明了多传感器图像的潜力。该项目的目的是制定适当的战略，利用多时相SAR和多光谱遥感数据监测农田撂荒情况。最后，应提供增强的地图，以便更详细地分析土地覆盖过渡的渐进过程。
