Ok, more to learn... (it's been one of those days...) I thought about using the Add Z Information—Help | ArcGIS for Desktop tool since it takes away one step and makes this a little easier of a process. BUT I found that just using this tool: Add Surface Information—Help | ArcGIS for Desktop that virtually all my problems are solved. I have to first create a Z field or so, then run this tool, and my Z data is populated based on the surface that I inputted for it. [more banging of head on desk]. Either way, I appreciate everyone's help! ... View more

Hi Subah, Can you be more specific on what software you are using and what processes/steps you are taking? If you are working with ArcGIS Pro, take a look at this link about symbolizing: Symbolize feature layers—ArcGIS Pro | ArcGIS for Desktop If you are working with ArcGIS Desktop (ArcMap), take a look at this link on symbols: A quick tour of symbols and styles—Help | ArcGIS for Desktop ...

Alright, I believe I have this figured out. I have been looking in an out of everything I can find and it was way easier than I imagined. Basically, using this tool: Create a LAS dataset—ArcGIS Pro | ArcGIS for Desktop There is a way to add "Surface Constraints". This was apparently what I was looking for. Steps: 1). Use Create a LAS dataset—ArcGIS Pro | ArcGIS for Desktop 2). Input the .las file 3). Add your Surface Constraints. In this case, my survey points acted as "anchor points" in the surface constraints 4). Run the tool. 5). To create the TIN, you first need to filter the LAS dataset to just show class 2, which is "ground". 6). Run this tool: LAS Dataset To TIN—Help | ArcGIS for Desktop 7). [Optional] You can filter out some of the extra data created by the TIN by using this tool: Delineate TIN Data Area—Help | ArcGIS for Desktop Thanks for your help, Dan Patterson ! Just going through the first link you sent got me to where I needed to be. ...ok... looking closely at this again, the SECOND link you wrote, Add Files To LAS Dataset—Data Management toolbox | ArcGIS for Desktop does allow me to add surface constraints.... Geeze... If I only read closer, I would have seen this through and through. [smacks head on desk several times] I should never have doubted you, Dan!  ... View more

Neil, this is great! I have 3D and Spatial Analyst. I looked over the spatial analyst functions you suggested and those wouldn't work as well as the first things you suggested. Here is what I did, based on your suggestions. 1). Run the Interpolate Shape—Help | ArcGIS for Desktop tool on my point dataset. Since I have raw LAS data (and in the form of LAS Dataset), this is my best option since my "surface" in which I am interpolating can be in the form of LAS (or TIN or raster). 2). Create a "Z" field in the newly created feature class. 3). Run the Add Surface Information—Help | ArcGIS for Desktop tool, utilizing Z as my elevation field.  4). Then, make a new field and subtract the two elevation values to see the difference (using 'absolute value' to factor out negative numbers). ... View more

Dan, I appreciate the reply. I agree and disagree. Though, like you said, it depends on the location of the TIN nodes. I played around with making my LAS dataset into a raster and it just wasn't behaving as well as I would have hoped. Though, this is likely on me not putting in the right parameters for creating the raster. I couldn't seem to get my raster data 'fine' enough for the Minus—Help | ArcGIS for Desktop  tool to show something other than zero. ... View more

...thinking about this more, is there a way to perform a spatial join (or equivalent operation) between a TIN and a point feature class? Or maybe between the point feature class and LAS Dataset? There does not seem to be a way through ArcGIS tools (and joins) but maybe there is another toolset out there that might be useful? thanks! ... View more

Hi Emmanuel, What browser are you using? Have you tried using a different browser to see if you have greater success? ... View more

Hi Derrick, Can you please give more details to what is happening? What software are you using? What steps did you take? Can you post a screen shot? It may also help to place this thread in a more appropriate 'place' since "Community Help" is mainly for the GeoNet. This link shows where you might find a better 'place' to move your thread to: GeoNet Community Structure ... View more

Owen, thanks for responding. This makes sense. ... View more

I am not sure since the Google+ and Facebook login thing is fairly new. What version of ArcMap are you running? I wonder if 10.4 would solve this issue. I would consult with Owen Evans​ or someone else on the Esri staff about this. ... View more

Thanks, I appreciate it. I am hoping for something obvious as well (though, maybe I am looking at this wrong and maybe it is something different from what I am thinking...). I welcome other comments! ... View more
