Lineament mapping in ArcMap to display as Rose Diagram

Recommended Posts

Hello,

I am a very new user of RockWare and wanted to see what people have been doing with rose diagrams drawn from data digitized in ArcMap. I have a personal geodatabase with polylines and would like to know how to display it as a rose diagram with orientations and total length within bins.

I have found ways of drawing rose diagrams if i can figure out how to gather X1,Y1 and X2,Y2 data but don't know how to do it in Arc - is this the only way to do a total length and orientation diagram?

Any ideas?

Thanks very much for your time,

Melissa

Hi Melissa,

Convert the ArcMap lineations to AutoCAD DXF and choose the Linears | Import | DXF Lineations menu command on the RockWorks Utilities tab to load the data in the format used by the Linears | Rose Diagram | From Endpoints command.

It looks like ArcMap has the ability to convert to DXF, and you can also use RockPlot/2D to import a SHP file and export a DXF file.

Thanks,

Tom B

Thank you very much for your advice earlier but don't know how to create xy data in ArcMap so converting it is not helping. I am just giving up on that option and hoping to start over; additionally I am not very good at learning how to use new software on my own even using the help.

I have some lineaments I am digitizing in ArcMap and in the attribute table can get the length and orientation to be added as fields.

How do I create rose diagrams one with total count and total length based on orientation of course.

Any ideas?

Do you guys have a tutorial/powerpoint/video/anything... like rockware for dummy's :)

Thanks so very much,

Melissa

Hi Melissa,

- ArcMap / ArcView uses the ArcToolbox Conversion Tools | To CAD or To Shapefile to export the lineaments a DXF or SHP file. Then use the method that I describe above to import the file into RockWorks and read the XY coordinates into the spreadsheet. You do not need to "create xy data in ArcMap" using this procedure.

- If you prefer to work with a list of orientations in your attribute table stored in a DBF file, you can import the DBF into the RockWorks spreadsheet with the File | Import | DBF menu command in RockWorks.

RockWorks comes with a tutorial in the Help file. Choose the Help | Tutorials menu command in RockWorks to view the tutorials.

You are welcome to download the RockWorks15 PowerPoint presentation from the RockWare web site. The PowerPoint slides focus on describing the features of the program rather than procedures of how to perform tasks, but you may still find the slides useful.

You are welcome to send me a ZIP file with your files and I will take a look. For files larger than 10MB, use the RockWare web upload link.

Thanks,

Tom B

Hey Tom,

I am sorry I have not replied to you in so long. I was crunched for time and went with Surfer to make my rose diagrams but now have more time to work on this again. I will see if I can figure it out based on your input above if not will send you some data to see how it works for you...

thanks again and hope you new year is going well.

Melissa.

Hi Melissa,

Thanks for sending your SHP file with the lineaments. The procedure I use to create a rose diagram follows below:

  • Open a RockPlot/2D window with the Window | RockPlot/2D menu command.
  • Choose the RockPlot File | Import | SHP menu command to display the SHP -> RockPlot2D Import dialog.
  • Specify the ESRI Shape File name and click on the Process button at the bottom left to display the SHP file in the RockPlot window.
  • Choose RockPlot File | Export | DXF menu command to display the DXF Output File name, and click the Process button in the lower left. Close the RockPlot window.
  • Click on the Utilities tab on the left side of the RockWorks window, and choose the Linears | Import | DXF Lineations menu command to display the DXF Lineation Import dialog.
  • Specify the DXF Input File, and click the Process button. Close the DXF Lineation Import dialog window to view the values in the RockWorks Utilities spreadsheet.
  • Choose the Linears | Rose Diagram | From Endpoints menu command to display the Rose Diagram From Endpoints dialog.
  • Specify the desired settings and click the Process button to display the rose diagram. You will probably need to change the Circles | Circle Spacing from Automatic to Manual, and increase the spacing so the labels to not overwrite each other.

Thanks,
Tom B

Dear Mostafa Shaaban,

RockWorks does not have any tools to extract the lineaments from a DEM or Landsat ETM image.

RockWorks can map lineaments and create rose diagrams after you have digitized the lineaments to polylines and saved to an AutoCAD DXF file. The Utilities section uses the Linears | Import menu command to load the data into the datasheet, then choose from the options in the Linears menu.

Thanks,

Tom B

Hi Prof.Dr/ TOM ,

Thank you very much for the fast reply to my question, and the fact that I am very grateful to you and I thank you very much, I applied the steps as written and it gave me great results as I made the rose diagram for lineaments.

Thank you very much
