Abstract
Existing building annotation methods require significant human resources or other costs, making it challenging to achieve both low cost and high efficiency simultaneously. Crowdsourced OpenStreetMap (OSM) data, with its extensive volume and openness, is widely used for annotation purposes. However, issues such as missing quality information and poor data completeness have hindered its potential to generate deep-learning samples. In this context, our research developed an automated method for generating high-quality building samples based on OSM and deep learning. To address the impact of poor OSM data completeness, we designed a Region-Of-Interest (ROI) generation algorithm to alleviate the negative impact of missing annotations during model training. Leveraging the superior performance of models specialized in the building extraction domain, we devised a method for selecting high-quality samples. Experimental results on the open-source simulation datasets WHU-SIM, MASS-SIM, and real environments in the San Angelo and Washington regions demonstrated the effectiveness of this method. We produced high-quality building samples with a resolution of 0.3 m for the San Angelo and Washington areas, enriching the available data in the building extraction field. This research advances the application of OSM in the remote sensing domain and provides comprehensive insights into its potential for automated sample generation in deep learning.
期刊介绍:
The International Journal of Applied Earth Observation and Geoinformation publishes original papers that utilize earth observation data for natural resource and environmental inventory and management. These data primarily originate from remote sensing platforms, including satellites and aircraft, supplemented by surface and subsurface measurements. Addressing natural resources such as forests, agricultural land, soils, and water, as well as environmental concerns like biodiversity, land degradation, and hazards, the journal explores conceptual and data-driven approaches. It covers geoinformation themes like capturing, databasing, visualization, interpretation, data quality, and spatial uncertainty.
