Examining winter fallow farmland from space and geography: a case study in Guizhou, China

期刊: JOURNAL OF SPATIAL SCIENCE, 2021; 66 (1)

Winter fallow farmland is increasing dramatically in some regions in China. Our goal was three-fold: (1) to develop a consistent procedure to identify......

Ocean wave height inversion under low sea state from horizontal polarized X-band nautical radar images

期刊: JOURNAL OF SPATIAL SCIENCE, 2021; 66 (1)

A SWH model under low sea state is established, the model is based on the information contained in the wave field to extract the deviation between the......

GNSSer: objected-oriented and design pattern-based software for GNSS data parallel processing

期刊: JOURNAL OF SPATIAL SCIENCE, 2021; 66 (1)

To cope with the construction and upgrading of GNSS, critical attention must be given to the maintainability, reusability, extensibility, portability,......

Combined GPS plus BDS instantaneous single- and dual-frequency RTK positioning: stochastic modelling and performance assessment

期刊: JOURNAL OF SPATIAL SCIENCE, 2021; 66 (1)

Combining the Global Positioning System (GPS) and the developing Chinese BeiDou Navigation Satellite System (BDS) positioning has received increased a......

One-step method for predicting LOD parameters based on LS plus AR model

期刊: JOURNAL OF SPATIAL SCIENCE, 2021; 66 (2)

This paper proposes a one-step forecasting method based on the LS+AR prediction model that calculates LS and AR model parameters simultaneously. The E......

Case library construction method using high-resolution remote sensing land cover classification information

期刊: JOURNAL OF SPATIAL SCIENCE, 2020; 65 (1)

Using high-resolution remote sensing images, we propose a case classification method using a land cover classification case library. Case-based reason......

A multiscaling-based semi-analytic orbit propagation method for the catalogue maintenance of space debris

期刊: JOURNAL OF SPATIAL SCIENCE, 2020; 65 (1)

The choice of orbit propagation method is essential for orbit prediction (OP) and determination (OD) of space debris, requiring both high accuracy and......

Spatial pattern of tourist attractions and its influencing factors in China

期刊: JOURNAL OF SPATIAL SCIENCE, 2020; 65 (2)

Based on the location data of 9820 A-grade tourist attractions in China, this study adopts the nearest-neighbour distance method, multi-distance clust......

A tensor-based interpolation method for sparse spatio-temporal field data

期刊: JOURNAL OF SPATIAL SCIENCE, 2020; 65 (2)

In this paper, a tensor-based interpolation method for spatio-temporal field data is proposed. The observed data are organized as a sparse tensor, whi......

Evaluation of multi-scale representation of ocean flow fields using the Euler method based on map load

期刊: JOURNAL OF SPATIAL SCIENCE, 2020; 65 (3)

This paper takes the map load as the evaluation indicator for multi-scale representations of ocean flow fields using Euler method. First, the map load......

Extracting croplands in western Inner Mongolia by using random forest and temporal feature selection

期刊: JOURNAL OF SPATIAL SCIENCE, 2020; 65 (3)

Reliable information of croplands has useful implications for agriculture. Based on random forest classifier, a cropland extraction method was develop......

Analysis of the importance of five new spectral indices from WorldView-2 in tree species classification

期刊: JOURNAL OF SPATIAL SCIENCE, 2020; 65 (3)

Spectral information mining plays a signi?cant role in tree species classi?cation using remote sensing images but a measure of the importance of the m......

A polarized reflectance model for remote sensing of densely vegetated surfaces

期刊: JOURNAL OF SPATIAL SCIENCE, 2020; 65 (3)

In this paper, we propose a modified model which takes the variation of leaf orientation in zenithal space into consideration. It is special because o......

Data fusion for a GPS/INS tightly coupled positioning system with equality and inequality constraints using an aggregate constraint unscented Kalman filter

期刊: JOURNAL OF SPATIAL SCIENCE, 2020; 65 (3)

It is well known that the unscented Kalman filter (UKF) has been successfully implemented for the integration of inertial and global positioning syste......
