| Abstract: | Based on actually surveyed data, an analysis on the precision of infrared distance triangulated heliograph survery was done according to law of propagated error. It is thought that infrared distance triangulated heliograph could take the place of the third and fourth leveling survey, which had great significance in selecting heliograph survey method for the forest area with complex topography and poor through sight conditions. |

| Keywords: | infrared distance triangulated heliograph survey law of propagated error |
