If your data is a shapefile or you can convert it to shapefile, you can open shapefiles in Google Earth without needing to convert to kml.  You can either click and drag the .shp in, or you can use File/Open then change the file type to .shp and navigate to where the file is stored. Once in google earth, it can be saved as a kml. Do you have terrain on in Google Earth?  That can sometime seem to skew kmls as well. ... View more

That warning is merely telling you what you already know, that your image files do not already have a spatial reference(yet).  The easiest way to find where your image was brought in to ArcMap is by right clicking on the image layer on the Table of Contents(Layer Panel) and selecting zoom to layer(likely at a very small scale).  It will likely be nowhere close to any of any value to you on your map, but thats okay. When you begin georeferencing, it will scale and rotate according to your control points and should be close to what you are needing once completed.  You will be needing to be zooming in and out and back and forth alot, so the zoom to layer will be of great help to you.  You will need to follow the fundamentals of georeferencing that Sephe posted, but it will be a process of matching a point on your image to a point on your data that would be the same.  The first set of matching points should fix your images location(the point on your image and point on your data should be the same), the second set generally fixes the scale so they match in size(likely your image is much much smaller than your dataset, usually are for my images).  The third and subsequent matched points, will fix any problems of rotation and warping of the image to properly fix your raster to your dataset. ...

Okay, some progress, some not. To fix the problem of lat/long key errors, they key needs to be changed to y and x in lines 296 and line 297.  I missed mentioning this earlier, apologies Next problem is the nv dictionary key on line 314.  OPeNDAP Dataset Query Form On the query form of the datasets this was developed on, there is a variable nv, which does not exist in the same format on the query form you are using, yours has nvdll, nvell, and nvel. I believe you need a combination of several of those for this to work, but not sure which since I'm not overly familiar with the data.  I know Curtis mentioned getting in contact with the person who developed it, and I would second that, since I'll admit I'm a bit out of my depth here, since I don't know this data or some of the modules he is using at all.  I think if you got the nv problem fixed it would work, since x,y,time, and nv are the parameters for the land xml which makes the tin.  ...

I can try to help you out with this further, its just a matter of having the time/access I need to do work on something like this.  Like you I'm a grad student and I'm off for the summer. I am not working in the lab where I was helping you with this previously and I can't do any work while at my day job.  I can put some time in later this week to follow up on where I got to, and from there I'm hoping its pretty simple to get what you were needing. ...

Why not take the output of your manual FC to FC conversion and copy it as a python snippet and see what is going on(Go to Geoprocessing Results, navigate to the process, right click and select copy as python snippet)?  From there it should be fairly easy to determine what changes you want to make and how to manipulate fields. ...

Hi Joe, Thanks for the information so far. To answer both of your questions, we would probably need more information, namely the code the tool is using.  Also if you could give us the full wording of the error code you are getting, that can help define what is causing the error. Posting Code blocks in the new GeoNet​ if you need help with posting code to Geonet follow that link, and posting code blocks is generally preferred to uploading a script(unless it is ridiculously long, which it shouldn't from the sound of the tool). ...

The Slope tool can calculate either based on your input parameters . ArcGIS Help (10.2, 10.2.1, and 10.2.2) The Slope Tool works on calculating the maximum change of z values for a cell based on all surrounding cells.  ArcGIS Help (10.2, 10.2.1, and 10.2.2) Therefore, when you run slope it may not match the slope of your stream since the direction of the slope of the stream may not be the maximum slope value for that cell, which is what the slope tool measures.  Perhaps you could subset your DEM to only pixels that intersect your stream line, then run slope on only those pixels.  Then the maximum slope should be more proximate to the slope of your streams since it should only consider pixels that the stream is in(flowing into or from). ...

I was channeling my inner Dan Patterson​ for this topic.  I tend to just answer questions, but as you are a fellow student, I figured this was a good learning opportunity and you'd get more out of it by getting advice and working out most of it yourself.  I would like to reinforce the value of using model builder to design workflows convert them to python, then using python to augment it and make it much more valuable.  It becomes a much easier way to set-up scripts and saves the time looking up the proper syntax for many of the geoprocessing operations you are likely to use. Glad you feel you have a better understanding now and good luck on your future work! ... View more

I believe you are overthinking how all this works too much. fc isn't an object, but is holding a string value, which is the name of the feature class in your gdb.  so when the buffer tool see fc, its actually reading the string that it contains and check your workspace for a fc with that name.  You need to have it use a string of your selection FC as input, so all you need to do is have the input add the rest of the file name to it. So you would want arcpy.Buffer_analysis(fc + "krogerselection" , blahblah other parameters) to get the selection fc(Bro_ADDSkrogerselection for the first time through the loop) instead of arcpy.Buffer_analysis(fc, blahblah other parameters) that gets regular fc(Bro_ADDS for the first time through the loop) ...
