Have you tried replacing the rasterLocation variable in your inputs with the actual path to test if it exists and works? ... View more

Looks like you are missing a slash after the folder path.  Try %rasterLocation%/fdr%Y% ... View more

You can set the Expression value in the Select Layer By Attribute tool by using the field value of the previous process with an inline variable: MYFIELD = '%Value%' Also make the Get Field Value result a precondition for your final select by attribute process. ... View more

It's almost easier to do in the JS API.  Same principle as my previous suggestion of having an image ID attribute in your point feature layer.  The images you can load in a raster mosaic and publish to an Image Service.  Then from the point image ID in your web map layer, you can set a definition query on your Image Service mosaic layer to only show the image with the related ID. ...

Try setting your input parameters as variables before running the Calculate Field step as on this example page: Calculate Field—Data Management toolbox | ArcGIS for Desktop  (search for the Calculate ranges example) ... View more

There seems to be limitations on the file types that can be displayed in the HTML popup.  In addition to having the file location as a field value, the popup also requires the content to be HTML formatted, so for a link to a raster image the field value would have to be <img alt="File" src="c:\imagery\image1.jpg" width="500" />.   If the popup or info content contains the image location, you can select-drag-and-drop to the Data Fram TOC and the image will load. ...

What about using the HTML popup tool?  Your point layer can have a field with the location of the image file.  Then when you click on your point feature using the HTML popup tool, the image will be displayed in the popup content and you can drag and drop the image to your Data Frame. ... View more

For the statistics part you can convert the polygon datasets to rasters with the same cell resolution and use the Cell Statistics tool.  If you want to get the proportion of the raster cell that is covered, you will need to convert your raster to polygon blocks and run an intersect with the polygon layers. What do you want to achieve by getting the proportional raster cell coverage? ... View more

I don't think the refresh method takes any arguments.  Rather redefine the widget.layers property to your new layers array and then call the refresh method. function refresh(curLayer){    widget.layers = [ {layer: curLayer } ];    widget.refresh(); } ... View more

So you want to labels to be automatically placed?  We also use something similiar to Panagiotis Papadopoulos​ suggestion where the user can place the label anywhere on the feature and set the label properties such as alignment, colour, size etc and it works pretty well. ... View more

Would it be an option to create an additional Map Service that only shows the label and no colorsymbology for the feature layer and then show that layer based on a layer definition?  That way the label positioning is also dynamic with the standard labelling engine. ... View more

I also struggle with this issue.  Funny thing is that you can easily do it in the Javascript API by using "Pixel Value" as identification field. ... View more
