A Levenshtein distance-based method for word segmentation in corpus augmentation of geoscience texts

open access: yesAnnals of GIS, 2023
For geoscience text, rich domain corpora have become the basis of improving the model performance in word segmentation. However, the lack of domain-specific corpus with annotation labelled has become a major obstacle to professional information mining in

A method for finding a least-cost corridor on an ordinal-scaled raster cost surface

open access: yesAnnals of GIS, 2023
The least-cost path problem is a widely studied problems in geographic information science. In raster space, the problem is to find a path that accumulates the least amount of cost between two locations based on the assumptions that the path is a one ...

Evaluation of temporal compositing algorithms for annual land cover classification using Landsat time series data

open access: yesInternational Journal of Digital Earth, 2023
In this paper, four widely used temporal compositing algorithms, i.e. median, maximum NDVI, medoid, and weighted scoring-based algorithms, were evaluated for annual land cover classification using monthly Landsat time series data.
