In this article, the role of the reactive oxygen species (ROS) hydrogen peroxide (H2O2) as a signaling molecule involved in plant response to a sudden change in light intensity will be considered in a spatial context. The relatively low reactivity of H2O2 compared with other ROS (Halliwell and Gutteridge, 1985) might suggest that it could diffuse from a site of production to initiate intracellu...

The fusion of remote sensing images has become one of the new hotspots in recent years. It can not only improve spatial resolution effectively, but can keep the integrity of the multi-spectral image. In this paper, we take the Hangzhou area as an example and put forward a new image fusion based on lifting wavelet transformation, and carry out the qualitative and quantitative comparison to the s...

In real time remote sensing it is necessary to know the quality of images obtained from the different satellite sensors. Pan-sharpening enhances the spatial information of input raw multispectral images. This paper focuses on the evaluation and analysis of eight frequently used image quality assessment methods to determine the preservation of spectral and spatial integrity in the pan-sharpened ...

Understanding the relationship between an index of biological community state and habitat is important for policy makers and environmental managers. A common approach to modeling this relationship is to use regression. However, this simple method becomes complicated when the data are clustered and have both within-cluster and between-cluster spatial correlation. This article proposes a Bayesian...

In this paper a constraint-based generalised object-oriented database model is adapted to manage spatiotemporal information. This adaptation is based on the definition of a new data type, which is suited to handle both temporal and spatial information. Generalised constraints are used to describe spatio-temporal data, to enforce integrity rules on databases, to specify the formal semantics of a...

While ecosystem services provide benefits at various spatial scales, often the decision to conserve an ecosystem lies with the local people. Knowing the perceptions of local landowners of the benefits provided by ecosystem services cannot only help in the design of efficient mechanisms for environmental conservation, but also in achieving the support of these mechanisms by the local stakeholder...

Large spatial variations in ionospheric delay of Global Navigation Satellite System signals observed during severe ionospheric storms pose potential threats to the integrity of the Ground-Based Augmentation System, which supports aircraft precision approaches and landing. Range-domain monitoring within the Ground-Based Augmentation System ground facility cannot completely eliminate all possible...

Over the last decade a number of states and cities in America have successfully established spatial data infrastructures that incorporate core spatial data such as the physical infrastructure layers, topography, road and rail networks and critical administrative databases like land parcel and administrative boundaries. New York City built its digital photogrammetric base map (NYCMap) from 1996 ...

This paper addresses the utilization of expert information in groundwater hydrology. Given that a fuzzy model of hydraulic conductivity can be provided by appropriate experts for some spatial domain, crisp measurements can be used to update the model using a fuzzy Kalman filter. The motivation behind this algorithm is to respect the relative integrity of each data source, while still taking adv...
