Assuming you want to replace the value of the PHw field with new values, your field calculator should look like this: Parser: VB Script Expression: phw Code Block: Dim phw If [phw field] > 0 and [phw_field] < 6.24 phw = (((6.5-(-0.6))2*1.5)) else [phw field] > 6.24 phw = 0 end if ... View more

S, you have a feature class of points, and you're trying to calculate the value of a field based on the phw field, is that correct? ... View more

I Guess I don't really understand the question. The DSM minus the DEM IS the canopy height. The values of the raster you created are the canopy height values. You could turn this into points, lines, polygons, even charts, whatever you want. If you can describe exactly how you need your result displayed, I'm sure we can help you get there. ... View more

HI Akshay, have you tried using select by location within a distance? ... View more

Hi Tina, is it possible that the projection/datum for your DSM has been incorrectly defined? A common problem is people attempting to change a projection by using the define projection tool, or by changing the layer properties. ... View more

I'm glad you found a solution, Matt. Do you mind marking the question as answered? Thanks! ... View more

Hi Dusan, I'm not clear what you're asking. Are you looking for the downstream order of your lines? You mention a python script. What do you want your script to do? ... View more

By the way, the profile graph would require the 3D analyst to be authorized/enabled, but I don't think that what you're looking for--it makes an elevation profile of a line feature. ... View more

Hi Ted, the DSM should be the first returns, or canopy top, and the DEM should be the last returns, or bare earth. The difference between the two would be the canopy height, so it sounds like you already have it. Are you just wondering how best to display the information? What is the client requesting? A shapefile, or something else? ... View more

In the label expression box returns can be used to organize your label, but they don't effect the resulting label. The \n character is used to actually enforce a new line in your label text. The same is true for your python script--you can use a simple return to go to a new line, and \n is only needed if you want your label text to have a line break. ... View more

Hi Arianne, are you absolutely sure that the projection/coordinate system is the same for ALL your input rasters, as well as the target raster? When you used the mosaic tool, did you have an extent set in your geoprocessing environments? It may be limiting the result. When you load the rasters into a project, do they all line up correctly where you'd expect? Have you tried zooming in and out on the mosaic result? Sometimes the pyramids don't draw correctly, although the data is there. ... View more

Have you checked to make sure you have network analyst installed, authorized, and enabled? ... View more
