Consistency-Aware Map Generation at Multiple Zoom Levels Using Aerial Image

The multilevel tiled map service is widely used and serves as a kind of digital infrastructure. These tiles are usually rendered from vector data, whose update needs to walk or drive with professional equipment check every point interest. This leads inconvenience expensive cost in timely updating maps. Compared aerial images much easier cheaper obtain. In this article, we propose novel (MLM) generation framework that can automatically generate accurate consistent maps multiple zoom levels images. It consists level-aware generator consistency-aware generator. able initial realistic details for each level. regards the at level sequence builds connection between them, so guarantee content consistency different levels. Furthermore, collect large-scale high-quality dataset called MLM Experiments on our show method outperforms previous state-of-the-art methods both comprehensive quantitative metrics perceptual quality.
