I can not find the kml files. I am not sure Arc Earth even saves anything when you "draw". Basically I opened up Arc Earth, used the draw tool, and dropped points on the base map and named them. They appear in a folder called "My Drawings" in Arc Earth. I am not sure how to save them permanently, or if ArcEarth automatically does. If it does it automatically, I can not find where it saves them too....

I am not being clear, I am sorry. I created the "points" in ArcGIS Earth. So they are there, in the MyData folder when I open the program. I am not sure how to get them out of there and into another program, or export them as a kmz, etc..

Well, I would hate to have to re-create these points in another program is the problem....

In my Data folder I have created a folder with about 10 points. I can not figure out how to export this folder as a KMZ..... anyone know how?

So, in google earth you could simply enter coordinates, such as, 46.078935 -121.929077 and it would plot the point for you. I can not get this to work in ArcGIS Earth. Anyone have any suggestions? Thanks

Objective: Obtain estimates of Gradient along a stream. Gradient is defined as the Rise in elevation divided by the length. I used a trimble GPS unit to walk along the edge of a stream while logging a line feature. I then exported this line feature to ArcGIS shape file, and then converted that into a File Geodatabase feature class. These polylines have zm coordinates, so I know they have elevation data. I have a set of points, that define segments of the line I collected. I thought if I can turn my polyline into a raster, I can then use the Extract Values with points tool to extract the elevation data from the raster with my points feature class. This would then allow me to calculate the change in elevation for that segment. Does this help?

Does using the Polyline to Raster work for this? This tool asks for a Value FIeld, and I am not sure what to put for this.....

Actually I have another Idea. Because I have all the associated other habitat data for these "segments" in a spreadsheet, I can actually just extract the elevation values for the points, then copy those into my spreadsheet and get the gradient figures from there....

Ok. I am not sure what the best route is to go about this. I have collected line features (basically streams I walk along) and they have zvalues. So I have a set of lines... I then made a set of points called Reach_Boundary. These are the up stream boundaries of a segment of the stream line. But they are just points. I have these points snapped right to the line. The upper boundary of segment 2 is the bottom boundary for 3, and so on up the line.. I also have a point file called Stream_Mouths that serve as the bottom boundary of the first stream line segment. This picture is an example of the data. THe line is the stream line with z information, and the points are segment boundaries. Notice on the far left point it is a brighter shade of Red, this is the stream mouth point, which is also the downstream boundary for the first segment. A segment is any portion between the lines.. I need to get a slope gradient for each segment. Should I first merge my point files, so the Stream_Mouth point and the Reach_boundary points are all in one feature class? Then would I convert my line work into a raster, and use the points to extract values? My though is I could make a new column in the stream boundary point feature called Start_ELEV, and END_ELEV then create a new column called GRAD which would be populated by taking the (differrence between start Elev and End elev and dividing that by the length of the segment) (aka Rise/run). Anyone think of a different way? Im brainstorming...

I think I got it, the 3rd value is elevation and is in meters! THANKS!!

I have used that tool, and my output is 1 359248.2555 78628.9096 150.5130 I am using HARN state plane south Washington for my projection.. How do I interpret those numbers?

I have 4 seperate point feature class files. Each one of them has only 1 point. These points were collected with a trimble, and I exported them to shape file then to geodatabase feature class. They do have z value information. I can check te attribute of the point and under the "Shape" column it tells me it is a Point ZM. I am trying to just get the Z information. I want to get the elevation data for each point. Not sure if I need to convert this point to a 3D point to get this information, or if there is another way. THANKS!

Is this correct? fields = ['RASTERVALU_12', 'RASTERVALU_12_13', 'Cumm_Dr_SQKM', 'Mean_Pr_MM']
with arcpy.da.UpdateCursor(fc, fields) as rows:
for row in rows:
if row[0]:
row[2] = row[0] * (32.82010551 * 32.82010551) * (0.000000092903)
if row[1]:
row[3] = (row[1] *(32.82010551 * 32.82010551) * 25)/(row[0] * (32.82010551 * 32.82010551))
rows.updateRow(row)

Okay I have the following code with arcpy.da.UpdateCursor(fc, fields) as rows:
for row in rows:
row[2] = row[0] * (32.82010551 * 32.82010551) * (0.000000092903)
row[3] = (row[1] *(32.82010551 * 32.82010551) * 25)/(row[0] * (32.82010551 * 32.82010551))
rows.updateRow(row) Where I get this error: PYTHON ERRORS: Traceback info: File "G:\Scripts\Threshold_IP_Scripts\GetStreamStatsA.py", line 32, in StreamStatistics row[2] = row[0] * (32.82010551 * 32.82010551) * (0.000000092903) Error Info: unsupported operand type(s) for *: 'NoneType' and 'float' ArcPy ERRORS: Any ideas? I am stuck!
