If you're mainly interested in the results, instead of an algorithm, you may want to check out OpenStreetMaps.
Otherwise, you should focus on computer vision solutions and a framework such as OpenCV in order to process raw imagery and filter out streets based on their features – which is not trivial.

如果您主要对结果而不是算法感兴趣，您可能需要查看 OpenStreetMaps。
否则，您应该专注于计算机视觉解决方案和 OpenCV 等框架，以便处理原始图像并根据街道特征过滤掉街道 - 这并非易事。

听起来这对于从“街道目录”出版商到军方的制图师来说都是宝贵的资源。
我确信专有商业软件存在，但开源和免费软件 - 可能不存在。
This sounds like it would be a valuable resource to cartographers ranging from 'street directory' publishers to the military.
I'm sure proprietary commercial software exists, but open source and freeware — probably not.
