Quick‐start guide
(WRITING IN PROGRESS)
This quick-start guide presents a standard workflow for Iskaffe, using the main tools in the order they are supposed to be used.
For more information and additional features, see the User Guide.
The standard workflow is:
- Choose folder of raw data files
- Convert files
- Load converted files
- Grid lines
- Examine data
- Analyze lines
- Import or draw survey limits
- Analyze survey
- Export results
Choose the folder containing the raw data files you want to import by clicking on the folder buttton in the top-left of the Raw files tab.
The supported files in the folder get listed below. The normal-font light gray indicates that they have not been converted yet.
Choose the files to select by cliking on the box corresponding to each file.
Click on the Convert button to convert the selected files.
You can follow the progress of the conversion process on the accompanying console. In a general manner, you can follow the progress of any progress in the accompanying console.
When the conversion is complete, the converted files now show in the list in bold-font black.
Choose the converted files to load by cliking on the box corresponding to each file.
Click on the Load button to load the selected converted files.
When the loading is complete, the loaded files now show in the list in bold-font green. The loaded lines also show on the Map view on the right with:
- vessel navigation (in black)
- start (triangle) and end of file (segment)
- approximate coverage (light colored polygon)
From the Process tab, grid all lines by specifying the desired grid size (in m) and clicking on the Grid button.
When gridding is complete, the backscatter grids show on the Map view, replacing the lines coverage.
Other data types were gridded in the process. They are available from the Gridded data displayed drop-down menu.
You can visualize bathymetry...
...slope...
... and acquisition mode.
When visualizing acquisition mode, click on the colour bar on the right side to show the list of modes.
The modes show in a pop-up window, broken down in two parts: the parameters that are constant in all loaded lines, and those that are variable.
From the Process tab, Line processing section, click on the Analyze button to run the line analysis.
Line analysis show the bad soundings (in yellow) and the bad pings (in red).
From the Process tab, Survey processing section, click on the Draw button to draw survey limits on the Map view.
Left-click on the Map view to add vertices...
Double-click to add the last vertex.
From the Process tab, Survey processing section, click on the Analyze survey button to run the survey analysis.
Survey analysis show the cells within the survey limits that do not contain soundings (in purple).
From the Process tab, Survey processing section, click on the Export survey analysis button to export all results.
The results exported include:
- The list of modes and results of the line analysis for each line (as a text file).
- The raster of cells with missing data resulting from the survey analysis (as a geotiff).
Batch processing tools allow running some of the processes without converting/loading/visualizing the files in Iskaffe. This removes and memory restrictions and allow running the process on an unlimited number of files.
Kopp finds all parameters in a list of files and track their changes.
From the Menu bar at the top, select Tools, then Batch processing, then Parameters analysis (Kopp).
The bacth line analysis runs the same line analysis algorithm as described previously.
From the Menu bar at the top, select Tools, then Batch processing, then Line analysis.
