What's with the 3 comma separated values showing up on the unique values and your table of contents? Your attribute table seems fine as it doesnt have them. What data type is the field?

Maybe some wrangling of the feature linked annotation would achieve this, eg adding a new field based on an updated expression.

Hi, In desktop 10.4.1 I've run the Get Layout Template Info tool and Export Web Map from a template mxd I've set up with text elements in the map which have been given names in their properties -> 'element name' box. Everything is fine with the service in the Portal Web App, which I added to the default print widget, the advanced options box allows me to enter a map title, subtitle, department etc. The only thing I don't understand is the order in which these are listed as inputs. I did think it was alphabetical but that doesn't seem to be the case. I can only think its related to the order in which they are added to the layout? I know/think the Get Layout Templates info tool creates a JSON, though I don't know where it's located to browse through it, as I can only add it as a result when I'm publishing the export web map script tool. Also any other advice on custom print templates and added functionality is very much appreciated.

I can only guess it wants you to pass them as parameters before the list rather than as magic numbers e.g buff_dist1 = 100 buff_dist2 = 200 buff_dist3 = 300 distanceList = [ buff_dist1' .... Also be aware your "riverbuffer" + ".shp" needs to change name during the iteration to reflect the input distance. Currently it will just overwrite with the same name. Use something like "Riverbuffer_" + str(distance) + "_ft.shp"

#set a list of 100, 200 and 300ft
#variables should be snake case btw...
distanceList = [100, 200, 300]
#buffer river by ieterating values supplied in distanceList
#for every number in distanceList, input this numbe as a variable in the
#buffer function below
#within the for loop, the 'distance' variable will represent a distance in your list
#If you dont pass this in with 'Feet' it will default to metres
#for the out_feature_class, I'll take this distance value, covert it to a string (str)
#and add it on to the end of the buffer name (concatenating).
for distance in distance_List:
out_feature_class = "riverbuffer_" + str(distance) + "_ft"
# turn your distance into a string with 'Feet' on the end
#e.g. "100 Feet"
distance_ft = str(distance) + " Feet"
arcpy.Buffer_analysis(in_features, out_feature_class, distance_ft)
print "buffer for distance " + distance_ft + " is done"

This will be very simple, however please provide more info such as the intro to your homework and your data.

Hi Benjamin, looks like you have everything set up. Merge your roads and streams/hydro buffers into one feature and run the dissolve tool. Use the erase tool to erase this buffer area from your possible sites. Using your trails buffer, use the intersect to to create a new final feature class which represents your suitable areas. NB. Can also use clip tool instead if desired. Merge—Help | ArcGIS for Desktop Dissolve—Help | ArcGIS for Desktop Erase—Help | ArcGIS for Desktop How Intersect works—Help | ArcGIS for Desktop

It wont take all the stretched values. If you set up the classified renderer on your symbology on your layer then drag and drop, it should bring in those ranges in the tool (close and reopen the tool window beforehand).

Use Create Referenced Mosaic Dataset. If the files which get removed and replaced in the raster catalog keep the same names, you will only need to create this mosaic dataset once, then it will simply reference the paths in the catalog. Ie create it once and that's it.

If you right click, properties, fields tab then at the bottom it may have a managed yes/no box. It looks like line 239 is deleting your old tiff and 243 is inserting the new one. I would copy all your tiffs into a new mosaic dataset, then set line 243 to copy new tiffs into the mosaic dataset. If this works be aware that line 239 will have to change to remove old tiffs from the mosaic dataset, or simply set 243 up to replace existing. I'd get someone to rewrite that whole script also.

We need to get terminology right. .tif is a tiff file outside a geodatabase. A raster dataset is a raster inside a geodatabase in FGDBR format. A Raster catalog is either unmanaged or managed (references raster file paths or contains the rasters respectively) and sits inside a geodatabase. This is also very outdated. A mosaic dataset sits inside a geodatabase and references rasters and is the recommended container.

Feature to point for each country to create centroud points. Make yourself aware of the output options in the help file. Also countries may have island territories and exclaves etc which will skew your points. Use select by location to find neighbouring countries for each country and point to line for each country selected. The actual process will be more involved than this simple explanation, and would best be scripted as it will need iteration.

Can you explain the steps of the code and what its doing/think it's doing. Does that code block work? I can see raster catalogues mentioned in the code. Full explanations of what the data is, looks like and what you want to achieve will help people to help you.
