7.7. Analyzing and Processing RiverSurveyor Data
This section describes the analysis and processing of data files collected using the RiverSurveyor
program. Collection of these data files was described in the previous section (§
7.6
– How to Col-
lect Data with RiverSurveyor ). Full details of all aspects of data analysis and review are covered
in Appendix E – Analysis and Review of RiverSurveyor Data . The following topics are covered
in this section:
•
Data Analysis Overview
•
Loading a RiverSurveyor Data File for Analysis
•
Viewing and Analyzing the Data Set
7.7.1. Data Analysis Overview
The analysis of a data file typically takes place in the office after measurements have been made
in the field. However, the
RiverSurveyor program is designed to operate in both the data collec-
tion and analysis modes simultaneously. That is, RiverSurveyor can record data into one file
while analysis is being done on a second file.
7.7.2. Loading a RiverSurveyor Data File for Analysis
To load a RiverSurveyor ADP data file (
.adp
) for analysis and/or post-processing, use the fol-
lowing steps as a guideline:
1. Start the RiverSurveyor program (
Start|Programs|SonTek Software|RiverSurveyor
). The
program should initialize to the startup screen (
Figure 7-1
).
2. To open a data file, do one of the following:
•
Click the
Open
button, and then locate and open the desired data file.
•
Use
File|Open
(or press
Ctrl+O
), and then locate and open the desired data file.
•
Use
File|1
(or
2
or
3
or
4
) to open a recently used data file.
Note : When you first create a data file, or if you move the file to a different folder,
we recommend you use a descriptive folder rather than the default of
c:\SonData
.
For example:
c:\SonData\RiverSurveyor\Colorado River\2003-03-05
.
3. On opening the file, RiverSurveyor will display the
ADP File Information
dialog box (
Figure 7-36
). This
box shows details about the measurement information
stored in this data set and contains the following:
•
File name and path (in title bar)
•
File size
•
Start and End times of data set
•
Number of profiles in data set
•
Maximum number of cells in a profile
•
ADP frequency and serial number
•
Types of integrated sensor data
•
User comments entered during setup
