| Abstract: | The paper introduces the surveying method and contents of long distance gas pipeline in mountainous area under the conditions between the inflexion stakes mostly obstructive and partly existing obstacles from upper air, as the coordinate can not be surveyed by GPS, combining with natural geographical condition of mountainous area, the total station tachometer can be used to measure the horizontal angle of inflexion indirectly, using polar coordinate method to measure the curve and surmounting obstacles to survey the curves. These methods can be applied for certain precision requirement. |
