I have done a survey 4 months ago, but for accuracy proposes when I repeat it again with tow kinds of prism (in total station menu was selected just mini prism).
1 Lieca round prism
2 lieca mini prism
But the result shown me the objects relocation than preveus work, in none systematic manner, a building corner the same location the other deffren or have skew than preveus work or other building in correct location in which was read a complete building by the same prism mini or round.
Any suggestion or ideas?
