We also test our algorithm on Google satellite imagery with OpenStreetMap labels, and find a 23% improvement over previous work.

City-scale Road Extraction from Satellite Imagery

no code implementations22 Apr 2019 Adam Van Etten

We find an aggregate score of APLS = 0. 73, and a TOPO score of 0. 58 (a significant improvement over existing methods).

SpaceNet MVOI: a Multi-View Overhead Imagery Dataset

no code implementations ICCV 2019 Nicholas Weir, David Lindenbaum, Alexei Bastidas, Adam Van Etten, Sean McPherson, Jacob Shermeyer, Varun Kumar, Hanlin Tang

To address this problem, we present an open source Multi-View Overhead Imagery dataset, termed SpaceNet MVOI, with 27 unique looks from a broad range of viewing angles (-32. 5 degrees to 54. 0 degrees).

You Only Look Twice: Rapid Multi-Scale Object Detection In Satellite Imagery

7 code implementations24 May 2018 Adam Van Etten

We further explore resolution and object size requirements by systematically testing the pipeline at decreasing resolution, and conclude that objects only ~5 pixels in size can still be localized with high confidence.
