You probably need to look at the Intersect—Help | ArcGIS for Desktop  tool, but do you really need to clip each feature on it's own?  Once you have intersected the line features with the polygon features, you can assign the polygon attributes to the line features.  Unless the line feature class is dynamic and you need to repeat the process frequently.  What is the rule for when the line feature intersects with more than one polygon? ...

Oh wow I didn't know about AGOL Ass Thanks for sharing.  Definitely going to use it! ... View more

If you save the map to a new map, is the layer still requested? ... View more

You should be able to pass an array.  I don't know anything about your model, but if you say that it works on the Desktop side with the parameters as passed in the http request, then I can't see why it would not work via the REST endpoint.  Can you provide the request header information with the parameters values? ...

I would think so.  Try loading a single band of the image layer. ... View more

I would rather use Excel to do it.  You can convert your table to Excel, where you can split the columns in two, apply formatting, select all the data, copy to clipboard, paste in your map layout.  Much easier! ... View more

Maybe you can test and modify the parameters passed in the http request directly in the GP service directory service page or the GP tool from which it was pubilshed to see that the input parameters are valid. ... View more

Just use the replace function to replace the commas with line breaks def FindLabel ([BENVA.%Burial_Data.NAM], [SDE_SPATIAL.GISADMIN.waugh_road_graves.GIS_Authority_Link]  ):    na = [BENVA.%Burial_Data.NAM]    if na is None:        na = [SDE_SPATIAL.GISADMIN.waugh_road_graves.GIS_Authority_Link]    return na.replace (",", "\n") ...

OK I see.  The user should not need to to worry about any "constant" parameters in your model, so only the "user defined" ones must be specified right? ... View more

You should be able to do it in both environments.  In Python you can just use a normal variable or pass the value inline, while in Desktop (I assume model builder) you can create a variable with a set value to use as input for another process or tool in the model. ... View more

What happens if you only pass the first parameter in the array?  Also make sure that the array-parameter is actually an array and not an JSON object or string. ... View more

For your first step you can use the Dissolve tool to "unsplit" the features by similar attributes. Not sure about the second step, but I reckon if it is a proper network dataset it should be easy to determine the start and end node for each river section.  Also take stream order into consideration here. For your last step you can have a look at the COGO tools.  Just make sure you are working in a meter-based projection. ... View more

First issue with this question, you asked about an ArcGISImageServiceLayer, which is inherits from a different class (DynamicMapServiceLayer) than a ArcGISImageServiceVectorLayer (GraphicsLayer).  I think the graphics layers always render on top of the Dynamic layers, but if the layers you want to reorder are all from the Graphics layer type, you should still be able to reorder them.  See this fiddle - click the switch button and layer order changes. ...

The click tolerance might cause that you are just missing the features with the click event and therefore nothing is happening.  Try setting the click event on the map object. ... View more

The layer order is index based with 0 being the bottom layer, so if you want to move a layer to the top then you can do it like this: var fromtop = 0;  // layer order of visibility from the top map.reorderLayer(layer, map.layerIds.length - 1 - fromtop); ... View more
