Select Observations

Select observations associated with vectors based on criteria you set. Selectable observations can be from any type of vector.

Note: The options with entries on both the General and GPS tabs are used for selecting vectors (postprocessed baselines). If you get no selection results, run the Process Baselines command.
Note: This is a database query; view filter settings do not apply.

To select observations:

Select Select Observations in Home > Selection.
Set the selection criteria you wish to use to select observations. You can set multiple criteria and check more than one box in each group. See Options below.
To add observations selected to the current selection, check the Add to current selection box.
To preview the selection in an open graphic view, Project Explorer, or Occupation Spreadsheet, click Apply. All points meeting all of the criteria are selected.
Refine the criteria if needed, and clickOK to make the selection and close the dialog. The number of selected observations appears on the status bar.
Click Apply if you want to see and refine the selection, or click OK to use the current selection criteria.


Options
General tab
From/To	Pick two points in a graphic view, or enter two point IDs. By definition, vectors have a direction.
Feature code	Enter the alphanumeric string used to identify a feature associated with the points you want to select.
Type	Check boxes for the types of observations you want to select.
Status	Check boxes for the status of vectors you want to select.
Observation ID	Note: An observation ID consists of the alphanumeric characters displayed in parenthesis at the end of the observation node name in the Project Explorer. The alpha characters used for observation IDs are as follows: - “V” is used for RTK vectors (for example, “V1”). - “PV” is used for vectors that are post-processed in the software (for example, “PV1”). - “IPV” is used for vectors that are post-processed in other software and imported into this software using a TDEF file (for example, “IPV1”). To select a single observation, enter the observation ID. To select a range of observations, enter the ID of the first observation in the range followed by three dots (...) and the ID of the last observation in the range. For example, you would enter `v1...v5` to select observations V1, V2, V3, V4, and V5. To select two or more non-contiguous observations, enter the name of each observation separated by a comma. For example, you would enter `v1, v3, v6` to select points V1, V3, and V6. Note that you can enter multiple ranges by separating each range with a comma. For example, you could enter `v1...v5, v10...v15.` Note: Alpha characters used in observation IDs are not case sensitive.
Sideshots only	Check this to exclude all observations but sideshots from the selection.
Start time/ End time	Select operators in the Start Time and End Time lists. Then, enter dates and times in the format shown in the Properties pane for vectors in your project.
Duration	Select an operator and type a time in the format: `Hour:Minutes`.
GPS tab - Observation with vectors with
Horizontal/ vertical precision	Select operators and enter precisions in the format shown in the Properties pane for vectors in your project.
Solution type	Code – The observation has an autonomous position. Fixed - The baseline processor was ableto resolve the integer ambiguity for the observation with enough confidence to select one set of integers over another. Float - The baseline processor was unable to resolve the integer ambiguity for the observation with enough confidence to select one set of integers over another. Mixed – The observation has multiple solution types assigned to it. RTK – The user-specified RTK horizontal and vertical precision tolerances for the observation were met during data collection. Unknown – The solution type for the observation is unknown. XFill - The user-specified XFill horizontal and vertical precision tolerances for the observation were met during data collection.
Field method	Continuous - Check this box to select data collected during a continuous trajectory. Event - Check this box to select occupations at points observed in a Real-Time Kinematic (RTK) GPS mode in which the resulting vectors include an 'event' marker. Observed control - Check this box to select occupations at control points observed in an RTK GPS mode. Rapid - Check this box to select occupations at points observed in an RTK GPS mode was collected at a fast data rate, such as every second. Static or fast static - Check this box to select occupations at points observed in a PPK GPS mode collecting up to 20 minutes or several hours (respectively) of raw data, and then postprocessing to achieve sub-centimeter precisions. Stop and go - Check this box to select occupations at points observed in short PPK or RTK Stop and Go occupations, while maintaining lock, and then postprocessing to achieve centimeter precisions. Topo - Check this box to select occupations at points observed in a GPS survey mode defined as topographic.
Antenna tab
Antenna heights	Enter antenna height parameters in the format shown in the Properties pane for vectors in your project.
Add to current selection	Check this to add the results of current selection to any previously selected data.
