This webapp provides functionality to process geophysical data recorded on third party audio recorders and outputs a GeoVue interactive report.

Recording :

Use the record data feature to acquire geophysical data using your device.
Provide a point number using the provided field
Then click on the "Rec" button.
Data will be recorded from your device using the current audio input port and saved to a ".GVR" file.
The recording is 30 seconds in duration as indicated by the countdown progress bar.
Once the recording is complete, the recording file will be downloaded to your device default download folder.
The file name will include the GPS coordinate of the recording and the specified point number.
Please store these recordings for later processing.

Login to account :

If data is to be processed, the user must first enter the user account login details for the account, in the provided username and password fields.
To process data, the user must also accept the terms of use check box provided.
The user may create an account by clicking the "Create Account" button provided.
If the user account does not have sufficient processing meters, the user may purchase meters using the "Purchase Credits" feature.
Other account functions such as Meters Remaining, Reset Password, and Delete Account are also available

Process data :

This section allows the user to set processing parameters.
First, the user must give the project a name in the provided text field.
Then, the user must specify the processing depth in meters below ground level that the data in the project must be processed to.
The user may apply filtering by checking the "Filter Data" check box. It is important to note that filtering the data changes the data. As such the user must inspect the data, using the chart, and determine it's acceptability.
In the event that audio data recorded with third party recorders is to be loaded, the user must load the coordinates of the recordings.
This is done by selecting the "Load Coordinate Data" button, then selecting the KML or GPX file containing the recording waypoints.
It is important to note that the elevation data for the recording waypoints must be included in the files. If not the elevation will be set to zero meters above sea level.
The waypoints must have the same number as the audio recordings, so for example, if the recording file is named "1.wav", then the corresponding waypoint name must also be "1".
Once loaded, the waypoints will be shown on the map.
If the recordings were done using the GeoVue Web-App, then it is not necessary to load a coordinate data file, as the GVR files hold the coordinate data in the file name.
Next, the user needs to select the "Process Data" button, then select the audio files to be processed. Multiple files can be selected.
The data will be processed and at the end of the processing procedure, a report will be downloaded.

The selected audio files must meet the following requirements:

Audio file must be no longer than 30 seconds in length
Audio file must contain 10 recorded hammer strikes
Wav file format - PCM
or mp3 file format - Standard 128kbps
or GVR file format
16-bit resolution
44100 Hz sampling rate
stereo channel

Chart :

To view the raw and filtered data produced by the processing procedure, the user can uses the chart feature.
The original raw data is shown in grey and the filtered data is shown in blue.
If multiple recordings were processed, then the user may select the point of interest from the drop list.
Data Quality Control information is displayed above the chart, indicating weather the data passes or fails quality control.
The number of correlating strikes detected, the correlation index of the strikes, the signal to noise ratio and quality control notes for the point selected are also shown.

Messages :

All processing messages are shown in this section.
Any errors will also appear in this section.

Download :

In the event that an error occurs during the processing procedure, any of the points successfully processed by the server can be downloaded from the GeoVue database.
Simply select the "Load Project Data" button and then select the points you want to download from the table presented. Multiple point data may be selected.
Once selected, click on the "Download Selected" button to download the data from the database.
These data files can be imported into the GeoVue application to generate a report, as described in the Import section.

Import :

In the event that an error occurs during the processing procedure, any of the backup files saved by the app may be loaded to produce a report.
Simply select the "Import Point Data" button and then select the point data files you want to include in the import. Multiple point data files may be selected.
Once loaded, select the "Generate Report" button to generate a report based on the loaded data.
The report will be downloaded to the device when generation is complete.
