Everything is on a server. It is odd to me and I am at a lost to explain why it takes so long . I'm starting to trhink it m,ay be more of a network issue. Anyway I've given up trying to export them out. I printed each one to a pdf individually. We have a hurricane bearing down on us and I have 14 different flood levels with 7 pages to each flood level. Can't waste time trying to figure out the export problem. Sounds like a network issue.  However, the more data you have in your layout the longer it is going to take. I have a particular project I export and there are a lot of things going on for each page and it takes upwards of 10 to 20 minutes to export a single page. You can speed things up by adjusting the quality.  Play with it a little bit.  Lower it way down and export review the quality and increase it until it is good. Use compression.  turn off all other programs when exporting.  Exporting to pdf can use up a lot of memory and other programs such a mail program etc chew up resources that ArcGIS could be using.  Pause your drawing while you export and turn off caching ...

Why not simply go ascii on it. replace & "°" & with &  chr(186) & 186 = º or you may have to go & chr(0186) & ... View more

On another train of thought. Using Data Driven pages. Have it clip the area that does not intersect your data area. If you have a polygon layer that you are using as your area of need you can re size it and re-run data driven page set up. Or you could base your data driven pages on a point feature and determine the diameter of the area shown and still clip. ... View more

Sadly it did not work.  I think if I had a more simple model it may have worked but I wanted to use the parameter as the beginning of 23 different sub operations. I don't really need the solution I just want it.  The model works fine IF I do the definition query to the Feature Class before running the model.  And as I won't have to run it to many times I can just remember to define the data first. If anyone else has any suggestions I would love to try them out. My model takes Transmission lines that are distinguished by Line Name (180 unique) Segment (23 different segments) and Circuit number (2 unique).  I then have 65000 poles some of which straddle segments and circuits.   What I am doing is extracting those poles and creating a new feature that segregates into grouping the structures by which line it is on and which segment and circuit.  and for those that straddle multiple segments and circuits it will create multiple structures.  Long story short I have the model working perfectly if I define circuit 1 or 2 and then run the model twice.  However, as I am doing this and finding drawing errors and fixing them and running it again etc etc... I was just looking for a way to streamline my process.  Not that it is a pain, I just want to know how at this point. ... View more

Thanks, I knew it would be something simple. I am going to plug it in and give it a test. Robert, wouldn't you do this with the "Make Feature Layer" tool from the toolbox. There you can add a sql expression. Will do the same thing as a definition in the properties. Only the selected data is passed on to the next process. You can probably copy your selection text from the dialog you do manually in ArcMap. Cheers, Neil ... View more

I have ArcGIS 10.2 on my machine.  I just looked in the Start menu and it shows Python 2.7 is installed. It's not the most recent (python is up to 3.x, ArcGIS uses 2.6 or 2.7 depending on your version), but from the bits of gossip I've heard, 2.x will probably be around for a while. Other than installing to a non-standard location, and adding the arcpy site package, I don't think Esri makes any significant changes to the distribution. You used to be able to install python before ArcGIS and then the ArcGIS installer could use the existing python install (still had to be correct version). I haven't run an install in a few versions, so I'm not sure if that's true anymore. I think arcpy requires specific versions of certain modules too, like numpy, so it may not be 100% cut and dry anymore. But all and all Python has been pretty handy. It's kind of like the Swiss Army Knife of languages. ... View more

I was just on the Python web site before replying. I see I can download Python for free.  It may come in handy for things outside of the ESRI environment.  Is ESRI Python use compatible with the most recent release of Python. www.python.org as well as any book published by O'Reilly (check online) These don't relate to ArcGIS but will get you up to speed.  Also don't forget the code samples in the help files http://resources.arcgis.com/en/help/main/10.2/index.html ...

Thanks, these are both great suggestions.  I am going to run the free course and see if my Supervisor will get the book ordered for me. ... View more

I would say it may be your technique and settings. In the line of the previous response.  click the Editor Drop down menu.  Under general turn on Classic Snapping and apply.  now open the snapping window and make sure everything is unselected. Now the drawback is you will not able to snap to vertices of other polygons.  So if you turn on what you want to snap to you can prevent snapping by holding down the space bar.  that disables all snaps. Are you trying to digitize INTO a existing Topology?  If so your Topology setting could be flattening out those lines based how your Topology was built.  I do not utilize topology in our field so I do not know for sure on that. Thanks for your reply.  However, I am still encumbered with this problem.  I have removed and rebuilt my editor toolbar with just the basic tools, disabled snapping, tried the same digitizing operation with another terminal in the office  ( other terminal works ). To reiterate, If I were to digitize a polygon feature with a portion of the polygon "------^-^-^-------" ; after finishing the part the return would be "----------------".   Simularly, if I were to digitize a multipart polygon with a narrow open space between edges, such as " ============"  my return might be  " =====        ======"  as ArcMap decides the open space between the polygon edges is insignificant and joins the two part feature into one.  I would appriciate any help in correcting this matter as I am about to start digitizing more of these type of features.

My apologies but it is difficult to understand exactly what you want to do. From an ArcGIS Session open the attribute table. From the drop down menu select export and export it as a text file. open the text file in Excel and convert it to XML Hi, I need some help, the information on this site is too confusing, nobody explains EXACTLY what you need to do.. so here is my question: I need a tool or edit de 'Export Data' tool, cause I need to get the atributes table, not the datagrid info. How can I do that? Please step by step. Thanks Renata ... View more

I am not 100% on this but a raster can be broken down into a point feature and the entire cell is a single value.  The area of the cell is bespoken by the resolution of the raster.  Hence if the resolution is 2 foot the center of the cell (the x,y) would be 1 foot from each side at a 90 angle.  Pythagorean Theorem would then be used to determine the min/max of the x,y  of the cell. Hi, I'm trying to calculate the area of multiple rasters on a cell by cell basis, that is from decimal degrees to square meters. I've put together an equation that calculates that (see attachment) but as I'm very new to python I'm having difficulties trying to get the X Min, X Max, Y Min, Y Max values for each cell into the equation. Any tips and trick that I can use to accomplish the task would be greatly appreciated. Thanks Toni ... View more

As a side note I was pretty good writing code in mapbasic in my MapInfo days. I am going to start looking at learning Python.  Just seems to me to many times when it is handy. Which would you rather learn, Python, C#, or C++?  Your only batch options are ArcPy, ArcObjects, and FGDB API (the latter two would require hundreds to thousands of lines of code, while Python would only require dozens). It would only take a few hours to learn enough ArcPy to start this. Don't bother with even looking at PGDB (size and compatibility).  I would strongly discourage exceeding 20Gb in a a single FGDB table (too many eggs in one basket).  It you're targeting ArcSDE, then don't bother merging FGDBs; do try to load either across or up/down tiles, to reduce spatial fragmentation. I started writing a standalone tool to transfer FGDB tables to ArcSDE but Microsoft  library compatibility issues (static v. dynamic) made for more work than I was willing  to take on.  My fallback plan was to export FGDB to ASCII, which then could be quickly bulk-loaded into ArcSDE with 'asc2sde', but I haven't have time to  mess with that either. - V ...
