Viewing Survey Data
Chapter 5
[Pos] .............................(position) The Pos view shows the observation coordinates relative to the station from which it was observed:
These views are illustrated in Figure 2. D

Figure 2: Various observation views
The RAW OBS view is the vector from B to D. The MC view is the vector from A to C. The Red view is H.dist and V.dist. The Pos view is position C. The illustration does not show the horizontal observation (angle), which is part of the raw view, or the azimuth, which is part of the MC and reduced views. Store the data in any of the views. When you look at the record again, it will be the view you selected. When you press one of the softkeys, such as [Red], the softkey changes to [Save]. If you press it again, that view will be saved. ([Save] is not displayed, confirming that the record is saved in Red view.) NOTE
Actual stored data does not change: the raw data is always retained. Only the method of data presentation changes.
Once you have saved a particular view, the SRX treats the observation as a record of that type for all other purposes. For example, if you save an observation in Pos view, it is subsequently treated by the SRX as a position record. Of course, you can change the view back to RAW OBS at any time. NOTE
SRX
The SRX does not permit you to view a backsight observation as anything other than an OBS. This avoids problems caused by recoordinating a backsight point.
