ClusteringDirectionCentrality

A novel Clustering algorithm by measuring Direction Centrality (CDC) locally. It adopts a density-independent metric based on the distribution of K-nearest neighbors (KNNs) to distinguish between internal and boundary points. The boundary points generate enclosed cages to bind the connections of internal points.

Human-Mobility-Analysis

A toolkit and models for individual and crowd level human mobility analysis based on trajectory data, including travel destination prediction, travel spatiotemporal and semantic features calculations (e.g., entropy, radius of gyration, motif ratio, travel rhythm, etc), driving characters and dispositions.

Spark-based-Ripley-K-Functions

A visual analytics framework for Distributed Ripley's K functions based on Apache Spark, including Space K function, Space-Time K function, Local K function and Cross K function. This framework consists of three parts, i.e., front-end web visualization components, Web service API component and back-end Spark-based algorithm packages.

gtwr-compute-platform

基于Vue.js, Echarts, Leaflet与Java Servlet实现的GTWR在线计算平台，支持原始计算数据预览、自定义计算参数进行GWR和GTWR计算，以及计算结果的评定

Spark-based-DBSCAN-Algorithms

A parallel algorithm package for DBSCAN based on Apache Spark, including KDBSCAN, KDSG and other optimized DBSCAN algorithms. This framework consists of three parts, i.e., front-end web visualization components, Web service API component and back-end Spark-based algorithm packages.

OGC-WMS-Discovery-Portal

A developing project to establish a geospatial web portal exclusively for discovering OGC Web Map Services by using multimodal or cross-modal retrieval technologies.

lodd

LoDD considers that internal points are surrounded by neighboring points in all directions, while neighboring points of a boundary point tend to be distributed only in a certain directional range.
