| Abstract: | The height information is important information of cultural features. It has a very important value in use. According to the analysis of the latest technology on the height measurement of cultural features, this paper describes two methods of the cultural feature height measurement based on the single aerial photo, one method uses the conception of projection error, the other one uses the collinear equation. Results of the experiment show that the two methods are all effective. |

| Keywords: | cultural features radiation distance projection error collinear equation |
