Lines to surface Tool doesn't account for gaps in rastrer surface #2

Closed acroskrey closed 6 years ago

acroskrey commented 9 years ago

Hi! Thanks for updating this tool and making it public!

I would like to say that I ran the "Lines to surface profiles" tool on a surface topography DEM and the "Borehole locations to borehole sticks tool" and they appear to have worked great.

The next thing I attempted was to add the surface profiles of buried formation tops and bottoms from rasters surfaces we interpolated from well log points. This may not be an intended use of the "Lines to surface profiles" tool. The lines look like they plotted along the Y axxis of the cross section correctly but not so much along the X axis. Some of the formations are not continuous and instead of spacing out the breaks in the formation contact line along the X axis the lines produced are abutted to each other and all start all the way to the left. As an example I have attached the same cross section three times. One image was created by a co-worker in ViewLog, one was created in the trial version of Strater, and then the third is only partially created using tools from this toolbox. Do you see in the first two examples how the green Cretaceous unit should be in two patches and the contacts are drawn right after the other in the third? I thought I could just edit this by making points along the topographic surface making the extend of the Cretaceous units and then sliding the lines over but I haven't been able to get the "Line intersections to cross-section features" tool to run.

Thoughts? Andrea

Hi Andrea, I will look in to this. The workaround for now is you could merge some dummy elevation data into your raster with nodata areas so that it is continuous and then edit the resulting line in cross section view.

Good idea. I’ll give it a try tomorrow.

Thanks for all of your help today!

Hi Evan, Making a set of new rasters that had the areas without data filled with dummy values work and I was able to make a fairly lovely cross section (see below). Thanks for your help! I was wondering if you knew how to add a vertical scale bar to the layout? Cheers, Andrea pva_xsection_uf-uf

Very cool! That's the most complete cross section anyone has sent me as an example, thanks.

For marking elevations you could start with the Fishnet tool in Arc Toolbox under Data Management. Leave the fishnet as it is or create it and then delete the lines you don't want until you only have ticks along the sides of the cross section frame. I haven't done this specifically myself, but I have used a similar tool in XTools to do the same sort of thing.

I have always hoped to include such a tool in the toolbox. We'll see

Hi , acroskey , I am trying to do a topographic section from a Dem with specific scales in vertical and horizontal... , can you write me the steps for doing that..thank you in advance...

acroskrey commented 8 years ago

Sorry! I haven't done this for over 1.5 years. I just used ethoms-usgs's ArcTool, which you can download from this site. I'm guessing, since it has been too long for me to remember, there is an option in the toolsets to set vertical exaggeration and that is what I think you are asking about. Unless you mean the scale you would like for print and that would be a simple cartographic fix in ArcMap layout view. If you are having trouble with the tool, you should ask a specific question about the tool. Good luck!

AlvaroMCMC commented 8 years ago

That's what I have , a line and a Dem. captura

At the end nothing show up.. what am I doing wrong?

acroskrey commented 8 years ago

Add the new feature you created (profile7.shp) to the GIS viewer of your choice.

AlvaroMCMC commented 8 years ago

Which one do you recommend ? Can I do that in Arcgis?

acroskrey commented 8 years ago

yep
