Special Issue Information

Dear Colleagues,

In recent years, thanks to advancements in sensing technologies and data collection methods, the field of environmental research has witnessed an unprecedented surge in the availability of spatial and spatiotemporal data. Such data, ranging from satellite imagery and remote sensing to ground-based observations, offer valuable insights into the complex interactions between natural processes and human activities. To harness the full potential of these datasets, sophisticated modeling techniques are required, capable of capturing the intricate spatial patterns and temporal dynamics inherent in environmental systems.

This Special Issue aims to bring together cutting-edge research and technological innovations in the development and application of spatial and spatiotemporal modeling approaches, including spatiotemporal geostatistical methods, chrono-topological analyses, artificial intelligence, temporal GIS, etc. This collection of articles serves as a platform for researchers, practitioners, and academics to share their expertise, techniques and findings, fostering a deeper understanding of environmental processes.

The scope of this Special Issue encompasses advances in a wide array of environmental domains, including but not limited to climate, ecology, geohydrology, ocean and marine sciences, atmospheric science, human exposure, and environmental health.

Remote sensing data are becoming increasingly important for quantifying long-term changes in land surfaces. Optical sensors onboard satellite platforms face a tradeoff between temporal and spatial resolutions. Spatiotemporal fusion models can produce high spatiotemporal data, while existing models are not designed to produce moderate-spatial-resolution data, like Moderate-Resolution Imaging Spectroradiometer (MODIS), which has moderate spatial detail and frequent temporal coverage. This limitation arises from the challenge of combining coarse- and fine-spatial-resolution data, due to their large spatial resolution gap. This study presents a novel model, named multi-scale convolutional neural network for spatiotemporal fusion (MSCSTF), to generate MODIS-like data by addressing the large spatial-scale gap in blending the Advanced Very-High-Resolution Radiometer (AVHRR) and Landsat images. To mitigate the considerable biases between AVHRR and Landsat with MODIS images, an image correction module is included into the model using deep supervision. The outcomes show that the modeled MODIS-like images are consistent with the observed ones in five tested areas, as evidenced by the root mean square errors (RMSE) of 0.030, 0.022, 0.075, 0.036, and 0.045, respectively. The model makes reasonable predictions on reconstructing retrospective MODIS-like data when evaluating against Landsat data. The proposed MSCSTF model outperforms six other comparative models in accuracy, with regional average RMSE values being lower by 0.005, 0.007, 0.073, 0.062, 0.070, and 0.060, respectively, compared to the counterparts in the other models. The developed method does not rely on MODIS images as input, and it has the potential to reconstruct MODIS-like data prior to 2000 for retrospective studies and applications. Full article
