Stephen Eldridge​ - I realize this is an old post, but did you already find the answer to your question? ... View more

Someone mark Jorge's answer as correct, please? ... View more

IMO - It's perfectly fine to cross post your question on other forums.  However, I also think it is helpful, for those trying to help with the OP, that the OP post a link to the same question on the other forum (full disclosure is appreciated by those who try to help).  Imagine taking the time to help someone and then later finding out that they had already asked their question somewhere else and were not included in that same discussion somewhere else, or if the OP gets their answer elsewhere while other people keep looking for a solution and trying to help the OP. In regard to "marking your own question as answered" I'm split on this topic.  I think the Correct answer is more coveted by those trying to help the OP.  From helping others myself, I know it can be disappointing when the OP marks their own question as the answer, especially since the correct answer is a nice form of recognition and gives the user points in the 'gamification' system.  From the perspective of someone looking for a correct answer it gets a little bit more complex - most likely future viewers of the thread don't care about points, they want to find the best possible answer to their own problem in a timely manner.  For a long thread with many responses, the user looking for a solution to their own problem will probably have to read most of the comments to fully understand and possibly find a solution to their problem.  Although, for future viewer the 'correct answer' may not be the one they are actually looking for.  Sometimes the user may find the answer somewhere else within the thread (possibly because their problem is similar but different and someone else's comment was the solution to their specific problem).  This is where the 'Helpful' tag on the comments proves it's value.  Anyone can mark a post as helpful and it awards the same number of points in the gamification system as a correct answer does.  It may be somewhere else in the thread...  It's important to realize that giving yourself the 'correct answer' does not award you any points in the gamification, but it might decrease the likelihood that the same user(s) will be willing to help you in the future.  I have felt this way before, although generally each situation is a bit different and open to interpretation. P V​ Maybe you can add a comment in response to the post that helped you find the solution and explain it in the thread for future users who stumble across this thread looking for a solution?  Just a few thoughts on the subject... ...

I agree with Sephe about not editing the data outside of Arc.  A join within ArcMap is a temporary link between the datasets.  Generally, I prefer to join the data (perhaps to see what matches or doesn't match) then if I like the results I will export it so that it is a separate static layer.  Although possible to edit the layer, I don't think it would not be possible to edit the excel data since that is data being joined from another dataset that ArcMap knows very little about.  Exporting the data will create a layer with Object IDs and all the fields you have turned on when exporting the join, after exporting the data is in an ArcGIS format.  Performance should be better on the exported layer too.  This will also remove data locks on your Excel spreadsheet should you need to edit it. However, remember that the export is a static layer and will not reflect changes to your Excel data after exporting.  If you need a dynamic layer that joins your excel data and GIS data, then I would suggest looking into SDE, where you can create spatial views that are basically dynamic joins where the data is managed by a RDBMS like SQL Server. ...

Click the symbology below the layer name, and then change the fill color in the symbology selector.  OR Right click layer name and goto layer properties, then Symbology Tab, then update the symbology there.  Video included below. ... View more

Also, when I initially start displaying my election results, the precincts are displayed correctly, but the rest of the map disappears; in other words, only the precincts appear in the map but I do not see any boundary lines or the rest of the map.  Is that normal? I would like the map to show an outline of the boundaries. I'm not sure I exactly understand what you mean by this, could this have something to do with your definition query? ... View more

I think when you have the excel file in your ArcMap it creates a data lock on the excel file for editing.  This is why I suggest exporting the data after performing the join.  Right click the layer and choose Data -> Export Data: From there you should be able to export the join as a separate shapefile or choose to store it as a feature class in a geodatabase.  If you need any further assistance exporting your data just let us know. ...

You may want to export the joined shapefile/excel table a separate layer and then work with it like that.  Maybe you have already done that though. ... View more

Yes, I'm sorry but there may be trail and error with that method.  I believe there is a way to add vertices along a line. (make the feature more complex) I will have to check on that though.  I can recall one time I had to do this and it did take some trial and error.  I needed to create an acre within a polygon. Given the amount of work to achieve the task, I would assume there is be a better way to do it, but I don't know what that method would be.  Maybe the parcel fabric as Chris and I suggested?  Then it becomes a cost benefit analysis.  Like almost any task - "what is the least cost path to achieve the goal? ASSUMING you're only going to do this once? or maybe once between now and the next software upgrade... or job.. etc. let us know what you find out in hindsight if it's valuable. I may not be able to get back to this for some time next week though. Sorry I know that is not very helpful at the moment.  maybe someone else will come up with a more elegant solution, I'll think about it some.  If you should figure it out please let us know what worked best. ...

For your question - it doesn't matter what shape the split off piece is? Just the acreage? ... View more

If doing it for just one polygon, I might use the measure tool to measure 2 acres of the north side, and maybe create feature edit tool and snap to vertices and create vertices where needed - does that make sense?  Then use the edit tool for Splitting a Polygon. If it were something you had to automate then it could take much longer and more complex math and scripting as Ian suggested - it could be very simple or very complex depending on your situation and scalability needed. ...

Sorry, nothing comes to mind immediately, did a little searching though.  I'm curious, what is the purpose of splitting it 50/50 (not that it necessarily relates to answering your question and of course you don't have to explain if you don't want to - simply curious that's all) Do you think this would work?  Is that parcel data, and do you already use parcel fabric?

Do you want to do it manually once or automate the process for many different polygons?  I'm guessing the polygons are not symmetrical... ... View more
