With the rapid socio-economic development of the country,the work of land updating investigation will surely developing toward accurate direction and the changed data obtained by GPS and other high-precision instrument can not blend well with the actuality chart data of the using about original land,resulting in the data obtained through surveying generated precision excursion,and survey is the one of the key links to solve the problem of Precision excursion.On this issue,this article conducted research trials within the range of the main city area of Simao,proposed a method to solve the problem of two different data fusion by least squares polynomial fitting algorithm,weakened the impact of land updating investigation on Precision excursion.
