Feature-based Map Matching for Low-Sampling-Rate GPS Trajectories
TL;DR: This work proposes a novel feature-based map matching algorithm that estimates the cost of a candidate route based on both GPS observations and human factors, and simultaneously analyzes a subsequence of coherent GPS points by utilizing a new segment-based probabilistic map matching strategy.

An Enhanced GAN Model for Automatic Satellite-to-Map Image Conversion
TL;DR: The proposed Semantic-regulated Geographic GAN (SG-GAN) is anticipated to reduce the manual identification efforts in broad geospatial applications and is versatile to various backbone GAN structures with a 20% performance improvement on three popular metrics.
