Special Issue Information

Dear Colleagues,

Very high resolution (VHR) remote sensing imagery and crowdsourced geospatial data provide innovative means for monitoring and modeling urban environments. The launches of commercial satellites with very high spatial resolution (VHR) sensors (e.g. IKONOS, QuickBird, Worldview and Gaofen), as well as unmanned aerial vehicles (VAVs) with VHR aerial photos and LiDAR data, bring a nonparallel opportunity for analyzing physical elements in urban environments. Moreover, crowdsourced geospatial data (e.g., OpenStreetMap, Point of Interest, and social media) bring new approaches to observe human-related characteristics of urban environments. Contrary to the availability of VHR (e.g. spatial, spectral, temporal, angle) imagery and crowdsourced geospatial data, the developments of state-of-the-art analytical techniques and novel applications in urban environments are still limited. It is highly necessary to develop innovative technologies and applications for creating a sustainable urban environment and alleviating negative impacts of urbanization.

This special issue calls for innovative techniques and novel applications for analyzing urban environments using VHR remote sensing imagery and crowdsourced geospatial data. Topics include but not limited to:

  • urban elements classification and information extraction from multi-source spatial data,
  • fusion and integration of VHR images and crowdsourced geospatial data,
  • urban change detection and dynamic analysis,
  • machine learning and spatiotemporal statistic methods,
  • image and data mining from multi-source, multi-scale, multi-temporal data,
  • urban growth and land use patterns and changes
  • urban population, energy consuming, impervious surfaces modeling
  • urban heat island and urban pollution
  • urban air, water and green space and their dynamics,
  • biodiversity loss and degradation,
  • human-environment interactions in urban environments, and
  • measuring indicators of sustainable urban development.

Video supervision equipment, which is readily available in most cities, can record the processes of urban floods in video form. Ubiquitous reference objects, which often appear in videos, can be used to indicate urban waterlogging depths. This makes video images a valuable data source for obtaining waterlogging depths. However, the urban waterlogging information contained in video images has not been effectively mined and utilized. In this paper, we present a method to automatically estimate urban waterlogging depths from video images based on ubiquitous reference objects. First, reference objects from video images are detected during the flooding and non-flooding periods using an object detection model with a convolutional neural network (CNN). Then, waterlogging depths are estimated using the height differences between the detected reference objects in these two periods. A case study is used to evaluate the proposed method. The results show that our proposed method could effectively mine and utilize urban waterlogging depth information from video images. This method has the advantages of low economic cost, acceptable accuracy, high spatiotemporal resolution, and wide coverage. It is feasible to promote this proposed method within cities to monitor urban floods. Full article
