Special Issue Information

Dear Colleagues,

Remote sensing is widely used nowadays in Earth observation processes, taking advantage of the different technologies being used in satellites. However, these data usually have low-medium spatial resolution and low temporal resolution, making the training of machine learning and deep learning algorithms a challenging task. So, these data need to be complemented with other data sources to enable better interpretations. Thus, public open data sources, as well as unmanned aerial systems and proximity sensors, are critical for the exploitation by integrating and analysing the collected data.

This Special Issue is addressed to the use of solutions to integrate remote sensing data with other data sources, in the context of Earth observation applications such as:

  • Ground, proximal and aerial remote sensing technologies for crop monitoring,
  • Urban and population dynamics characterization (locating new construction and settlements or building alterations, among others)
  • Forecasting, mapping and monitoring natural disasters
  • Land-use and land-cover monitoring and modeling for decision making,
  • Forest and vegetation dinamics monitoring and modeling,
  • Land surface water, atmosphere and environment dynamics, and many more.

 Topics of interest include, but are not limited to the following:

  • Remote sensors
  • Sensor technology and application
  • Internet of Things
  • Signal processing, data fusion and deep learning in sensor systems
  • Sensing systems
  • Localization and object tracking
  • Pixel and object based classification
  • Remote sensing ontologies
  • Remote sensing big data
  • Web Semantics
  • Multiscale data processing
  • Sustainability and climate change
  • Precision agriculture
  • Smart cities and urbanism

Wildfires are becoming more frequent in different parts of the globe, and the ability to predict when and where they will occur is a complex process. Identifying wildfire events with high probability of becoming a large wildfire is an important task for supporting initial attack planning. Different methods, including those that are physics-based, statistical, and based on machine learning (ML) are used in wildfire analysis. Among the whole, those based on machine learning are relatively novel. In addition, because the number of wildfires is much greater than the number of large wildfires, the dataset to be used in a ML model is imbalanced, resulting in overfitting or underfitting the results. In this manuscript, we propose to generate synthetic data from variables of interest together with ML models for the prediction of large wildfires. Specifically, five synthetic data generation methods have been evaluated, and their results are analyzed with four ML methods. The results yield an improvement in the prediction power when synthetic data are used, offering a new method to be taken into account in Decision Support Systems (DSS) when managing wildfires.

The spectral mismatch between a multispectral (MS) image and its corresponding panchromatic (PAN) image affects the pansharpening quality, especially for WorldView-2 data. To handle this problem, a pansharpening method based on graph regularized sparse coding (GRSC) and adaptive coupled dictionary is proposed in this paper. Firstly, the pansharpening process is divided into three tasks according to the degree of correlation among the MS and PAN channels and the relative spectral response of WorldView-2 sensor. Then, for each task, the image patch set from the MS channels is clustered into several subsets, and the sparse representation of each subset is estimated through the GRSC algorithm. Besides, an adaptive coupled dictionary pair for each task is constructed to effectively represent the subsets. Finally, the high-resolution image subsets for each task are obtained by multiplying the estimated sparse coefficient matrix by the corresponding dictionary. A variety of experiments are conducted on the WorldView-2 data, and the experimental results demonstrate that the proposed method achieves better performance than the existing pansharpening algorithms in both subjective analysis and objective evaluation.
