Quickly Calculate the Distance between Two Points and Measurement Error Based on Latitude and Longitude

LI Zhen-xi;LI Jia-xun;Guangxi Zhuang Autonomous Region by Information of Remote Sensing and Mapping Institute;The Second Institute of Surveying and Mapping of Guangxi;  
Directly calculating the distance( arc length) between two points and measurement error by using latitude and longitude,can reduce the link that geodetic coordinates transform into plane coordinates. By deducing the formula of longitude at the arc length of each latitude degree,combining with Excel spreadsheet,can achieve the purpose of rapid operation obtaining the distance( arc length)between two points and the measurement error. This make the calculation simple and convenient,and also improve the calculation method.
