"There's a lot of technical challenges but I don't think they're insurmountable," he said, of building a ribbon 100,000 kilometres long.

"有許多技術(shù)上的挑戰(zhàn)但我不認(rèn)為那是不可戰(zhàn)勝的"，對于建造一根長100国产日韩精品一区二区久久，000千米的帶子這一點(diǎn)九九色精品国偷自产视频下载，他說。

Professor Spinks said carbon nanotubes were so far only 10 centimetres long, often impure, and there were the logistical problems of building a continuous ribbon.

In this paper ,we utilize the imagery with greater 1 meter resolution which is so called very high resolution as experimental data and do the research of ribbon road and simple building roof , and we talk about the process and method of extraction from high-resolution remotely sensed imagery :the representation of road and building in high-resolution image is analyzed ;a method of semi-automatic extraction for ribbon road based on angular texture signature and profile matching is promoted ;a algorithm for road extraction based on Snakes model is compared and analyzed ;the method of object-oriented image analysis and classification is introduced and we utilize this method to extract simple building roof semi-automatically ;the algorithm of road extraction is implemented as prototype system ;finally , the practicability of above-mentioned method are evaluated .
