At the scale of your display, these lines appear to be coincident, but in reality they're not: I've exaggerated the difference between the two lines using the "Magnify Topology" tool in JTS TestBuilder, which I highly recommend for looking into cases like this. Depending on the goal of your analysis, it might be suitable to snap your vertices to a grid ...

So it's actually very simple, as suggested by @FelixIP: Spatial join one to many in ModelBuilder, then export the resulting table to excel and create a pivot table to summarise values of the B polygons.

There is no built-in functionality to do this. I don't think that Python can detect highlighted rows in a layer or table. Even ArcObjects has a hard time with highlighted rows. I would rethink this workflow. I would just add a LINK field to the meters table and simply copy/paste the ObjectID value or other Unique ID value of the point record you would have ...

Buffer your lines by a small amount with the dissolve option set to All. Do not include any dissolve fields so that a single buffer feature is created. Then run the Multipart to Singlepart tool to break the buffer apart into the set of single part polygons that do not actually touch each other. The polygon with the largest area will cover the lines in ...

The tile layers are image tiles (unless you are pulling from the new Vector Tiles services), so all the data in them is flattened into an image. There would be no way to 'vectorize' them. I think ESRI vector tiles are still in Beta development, and I have no idea whether they are planning to allow you to export them as a map other vector formats (eps or ...

While I agree that @RichardFairhurst's answer is the quicker and better way to do it, it is actually possible to make the selection of a meter and selection of a table record and have the meter update from the table the way you describe it in your question. import arcpy tblview = arcpy.mapping.TableView('WaterMeterTable') featlyr = ...

As people pointed out in the comments, switching to a different version of QGIS (in my case, the 2.8 long term release) fixed this issue.

I believe the red layer is what you're after, yes? I used the "Polygon intersection" tool from the processing toolbox (under Geoalgorithms, Vector, Polygons)

The query should use ST_UNION to make sure that the linestrings are clipped at all the points they intersect and a lateral join so it would use the proper indexes. SELECT row_number() over() AS gid, ST_CollectionExtract(ST_Multi(ST_Difference(a.geom, b.geom)), 2)::geometry(MultiLineString, 27700) as geom FROM lines a ,LATERAL ( SELECT ...

Making ArcGIS for Desktop play sound on speaker when model completes? Also includes instructions for emailing you on completion. I've used it, and it works...although it only fires on completion.
