Geopsy: Set receivers

Set receivers option allows to edit and ..... positions of receivers in a relative or absolute reference system. When the set receiver button is pushed in the Edit menu a window appears in which station positions are displayed as a table. Default fields displayed in this table are: Station name, X, Y & Z coordinates. Coordinates are usually expressed as cartesian distance in meters from an arbitrary origin point. Receiver positions can be edited in different ways. A first option is to edit the relative position of each selected station directly by typing it in the X, Y & Z fields. It is also possible to add station in current selection pressing the add station button. A second option is to load a coordinate file in ASCII format. This four column file has to contain receivers names and relative X, Y & Z coordinates. It has to be noted that station names cannot contain blanks. An example is provided hereafter.

# Station_name        X      Y       Z
# (station_name cannot contain blanks)

WA_WAU02 2056 2040 0
WA_WAU03 2044 2048 0
WA_WAU04 2052 2048 0
WA_WAU05 2060 2048 0
WA_WAU06 2048 2056 0
WA_WAU07 2056 2056 0

When the load button is pressed it is possible to browse to the directory of the selected coordinate file and open it.

Starting from this window it is possible to display the absolute distance in meters and the azimuth in degrees calculated between any receiver pair. In order to calculate distances beetween receiver pairs, push the Rel. pos. button in the Set receivers window; in this way a new window appears. In this window you can press the add button in order to display distance and azimuth between receiver pair. You can select any receiver pair clicking in the cells that contain the receiver names. Furthermor it is possible to add (and remove) new receiver pairs as rows in the same window and display the average distance and azimuth.
