    The assessment of slope stability and rock excavatability

     · Introduction The slope stability analysis of rocks is vital for designing safe slopes in openpit mines. A proper slope design not only leads to improvements in slope stability and safety but also reduces costs extends the life of mines and decreases the stripping ratio (Bye and Bell 2001 Naghadehi et al. 2011).

    Chapter 5 Land Surveying and GPS

    Chapter 5 Land Surveying and GPS. 1. Overview. As you recall from Chapter 1 geographic data represent spatial locations and nonspatial attributes measured at certain times. We defined "feature" as a set of positions that specifies the location and extent of an entity. Positions then are a fundamental element of geographic data.
