Special Issue Information

Dear Colleagues,

Smart cities are being built to help make cities better places to live, work, and play while reducing their carbon footprint. Smart cities are municipalities that adopt cloud/edge computing technologies and IoT solutions to improve the construction, management, and surveillance of urban space, of which the growing abundance of remote sensing data and emerging remote sensing technologies are an integral part.

Spatial information such as remote sensing images is the most important basic information for smart city construction and services. Remote sensing technology is an essential technical means for the dynamic collection and monitoring of urban spatial information because of its wide spatial coverage and high efficiency. The comprehensive use of a variety of remote sensing technologies and cloud service modes can enable the intelligent service system of regular and all-around remote sensing monitoring on a regional scale, thus providing a strong spatial information guarantee for smart cities. This Special Issue encourages researchers to focus on the exciting field of monitoring, identifying, representing, and predicting urban space using multi-platform remote sensing, with the support of various spatial big data. New theories, technologies, and applications that aim to address the challenges of modeling and analyzing smart cities, improving regulations for urban development, and optimizing urban spatial planning decisions using multi-platform remote sensing are very welcome.

Relevant topics include but are not limited to:

  • Remote-sensing-oriented spatiotemporal data architecture for smart cities;
  • High-resolution remote sensing image databases for smart cities;
  • Multi-source remote sensing cloud platforms for smart cities;
  • Remote sensing index systems for smart city evaluation;
  • Multi-platform remote sensing technology for smart city monitoring;
  • Multidisciplinary applications for smart city management using remote sensing;
  • Future scenario forecasting of smart cities using remote sensing and GIS.

Due to atmospheric scattering, solar radiation, and other factors, the Ice, Cloud, and land Elevation Satellite-2 (ICESat-2) product data suffer from a substantial amount of background noise. This poses a significant challenge when attempting to directly utilize the raw data. Consequently, data denoising becomes an indispensable preprocessing step for its subsequent applications, such as the extraction of forest structure parameters and ground elevation data. While the Density-Based Spatial Clustering of Applications with Noise (DBSCAN) algorithm is currently the most widely used method, it remains susceptible to complexities arising from terrain, low signal-to-noise ratio (SNR), and input parameter variations. This paper proposes an efficient Multi-Level Auto-Adaptive Noise Filter (MLANF) algorithm based on photon spatial density. Its purpose is to extract signal photons from ICESat-2 terrestrial data of different ground cover types. The algorithm follows a two-step process. Firstly, random noise photons are removed from the upper and lower regions of the signal photons through a coarse denoising process. Secondly, in the fine denoising step, the K-Nearest Neighbor (KNN) algorithm selects the K photons to calculate the slope along the track. The calculated slope is then used to rotate the direction of the searching neighborhood in the DBSCAN algorithm. The proposed algorithm was tested in eight datasets of four surface types: forest, grassland, desert, and urban, and the extraction results were compared with those from the ATL08 datasets and the DBSCAN algorithm. Based on the ground-truth signal photons obtained by visual inspection, the classification precision, recall, and F-score of our algorithm, as well as two other algorithms, were calculated. The MLANF could achieve a good balance between classification precision (97.48% averaged) and recall (97.96% averaged). Its F-score (97.69% averaged) was higher than that of the other two methods. This demonstrates that the MLANF algorithm successfully obtained a continuous surface profile from ICESat-2 datasets with different surface cover types, significant topographic relief, and low SNR.

The new type of multi-temporal global land use data with multiple classes is able to provide information on both the different land covers and their temporal changes; furthermore, it is able to contribute to many applications, such as those involving global climate and Earth ecosystem analyses. However, the current accuracy assessment methods have two limitations regarding multi-temporal land cover data that have multiple classes. First, multi-temporal land cover uses data from multiple phases, which is time-consuming and inefficient if evaluated one by one. Secondly, the conversion between different land cover classes increases the complexity of the sample stratification, and the assessments with different types of land cover suffer from inefficient sample stratification. In this paper, we propose a spatiotemporal stratified sampling method for stratifying the multi-temporal GlobeLand30 products for China. The changed and unchanged types of each class of data in the three periods are used to obtain a reasonable stratification. Then, the strata labels are simplified by using binary coding, i.e., a 1 or 0 representing a specified class or a nonspecified class, to improve the efficiency of the stratification. Additionally, the stratified sample size is determined by the combination of proportional allocation and empirical evaluation. The experimental results show that spatiotemporal stratified sampling is beneficial for increasing the sample size of the “change” strata for multi-temporal data and can evaluate not only the accuracy and area of the data in a single data but also the accuracy and area of the data in a multi-period change type and an unchanged type. This work also provides a good reference for the assessment of multi-temporal data with multiple classes. Full article
