If you want to show changes in occupancy rates, why not run an overlay (e.g Identity or Union) and then use the data from that to compute the changes for each polygon and store the result in a new field in that layer, then symbolize that layer using the new field? ... View more

You could use lines created from the polygons once they've been planarized to get rid of overlaps.  We typically work with lines, points and polys as part of our normal procedures.  In your case, however, it might require an extra feature class, but a line feature class has other benefits, such as allowing symbology categories, definition queries, ease of editing lines, etc. ...

I don't think you can easily get what you want in ArcMap yet. See http://blogs.esri.com/esri/arcgis/2010/03/19/adding-a-declination-diagram-in-arcmap/ but in 10.1 things are a bit easier in that you can manually set the angle through the properties. As for getting what you want, here's a link to the Ideas: http://ideas.arcgis.com/ideaView?id=087300000008E0a&returnUrl=%2Fapex%2FideaList%3Fc%3D09a300000004xET%26category%3DProduction%2BMapping%2B%2528PLTS%2529 ...

If you want additional data frames on some pages and not others, and in different locations, see http://forums.arcgis.com/threads/40832-Multiple-data-driven-frames, and see http://www.arcgis.com/home/item.html?id=0ba4fd37e2e54f65b3edf6478e8cc30a Another option is to use one DDP project (perhaps a copy of your main one with a simple closeup extent) to create your closeups and export them as a raster such as a tif.  Then use the dynamic pictures option of Data Driven Pages to control what picture shows on what page and the location of each.  See http://betablogs.esri.com/beta/arcgis/2011/11/28/dynamic-pictures-in-data-driven-pages/.  If you export all your closeups to one folder from a DDP, then it makes it much easier to add the paths to the DDP index table (calculate the path into all and then just add the unique name), and you have the added ability to easily update the closeups simply by running the closeup DDP prior to running your main DDP. ...

Perhaps not as easy as the align edge, but you might be able to do the following two step in a kind of batch mode.  Select your parcel features, then use the split tool to cut off any overlap in the land use features.  Delete the overlaps.  Select your parcel features and use the construct features using existing features tool to fill in the gaps.  Merge the gaps with the appropriate feature. ...

Depending on your particular circumstances, you could add your selected polygon or polygons to your line layer, in a way that adds them as line, run the planarize tool, and that will split all the lines at the polygon edge.  It's best to have a unique attribute (or a unique lack of an attribute) so you can simply select the polygon lines to remove them from your line layer.  You still have to go around and select the lines for deletion although you have multiple selection tools to grab more than one at a time. ...

A quick answer once you are in the middle of your selection process, is to switch the selection.  Depending on your data, missed sections should show up as bright blue letting you know you missed them.  Less simply, you can use your selection to create a temporary layer in the TOC, and then examine that for misses in various ways including symbology, but if it is fine export it to a new feature. But if you are often finding this as a problem, and roads from public sources often have incredibly small sections, gaps, attribute errors, perhaps even overlaps, it might pay to process them ahead of time to make selection, symbology, analysis, etc. easier.  Setting up a topology to validate your roads may fix gaps under the tolerance, as would running an Integrate. As noted you could set it up to identify dangles.  Running the unsplit tool could get rid of all those little sections that share the same attribute but are unnecessarily split.  A planarize would get rid of overlaps and split lines where they meet.  You might need to explode features if you have multiparts.  Finding small sections with attribute errors is harder, you might try selecting for different attributes and then visually looking for those little blobs of blue, or focusing on segments of very small lengths.  If you have ETGeowizards there are several tools, including the pseudo nodes nodes and clean tools, that can fix things. ...

I've had it work fine in several of my 10.1 DDP projects exported to geotiff using some arcpy code, and these have had some pretty complex labels in large layers.  There are a lot of maplex settings you might play around with in the placement properties for a layer and within the label weight and priority settings of maplex generally.  Some improve your ability to place a label, but some also would keep a label from being placed.  It might be worth it to just set aside some time and manipulate different settings to see what happens.    The Best setting not surprisingly works best but it is slower.  If you have a lot of complex label expressions, and/or multiple classes and definition queries for them, and/or label feature weights or placement options,you can overwhelm maplex.   You might also use the options to show unplaced labels in a color (default red). ...

I think it is working for me too, Joe, I just found it interesting that the registry entry doesn't affect the normal.mxd setting, and further that the normal.mxd can in effect switch off the registry setting for an ArcMap session, i.e. for all the maps that I open in ArcMap until I close it.  I think I actually kind of like that; it gives me some options. ...

I can't be sure what has happened from the image, so I'll just suggest one thing I've found when using the trace tool to create polygons that ends up looking a bit like your image.  Instead of double clicking or hitting F2 to finish, switch back to the 2 line tool and click once using it, then double clicking or use F2 to finish the sketch.  You might see if just clicking once while using the trace tool and then double clicking/hitting F2 works since that's easier.  It doesn't happen all the time to me, but simply trying to finish a polygon with the trace tool seems to lose all the trace after the last click. ...

I've tested this on my computers and got some interesting results.  On my secondary XP computer the registry setting did work if I chose to create a new map based on the �??blank�?� map of �??My templates�?� , or if I opened previously created map projects.  They opened with the classic snapping setting checked. But if I instead opened a new map based on my normal.mxd (which does not have the box checked), they opened with the snapping setting unchecked, and any map I opened after it in that ongoing ArcMap session had the setting unchecked. On my Windows 7/main computer, I had saved my normal.mxd with the classic snapping box checked and I don�??t yet have the registry tweak in place.  Any new project based on the normal.mxd or any previously created project that I opened thereafter in a continuing ArcMap session had the setting checked.  But if I started a new ArcMap session then maps based on the �??blank�?� template or previously created maps opened with the setting unchecked. ...
