hi, I am trying to do a time animation of a street network based on traffic numbers. These numbers change every 15 minutes. So my data is for 6 hours having 24 observations (6 x 4) . When I enable time, only dates are detected and not the granular minutes. In my case, since the date is the same, the is no time visualization to see, the vector file remains static. So I am unable to visualize time enabled data. I am attaching the data. I have made a subset to make it easier to look at it. I have intentionally kept the time intervals valid for just one line feature to simply the data. You will see in the data a column "times" which shows the time intervals and a column "flow". I would like that the thickness of the line changes based on the flow value that is varying on these time intervals. Any guidance will be appreciated

Can you provide a code sample? I'm not able to reproduce this, as.Date and POSIX date objects are being converted to a Date field in an output geodatabase in my tests. Here's an example: library ( arcgisbinding ) arc . check_product ( ) Sys . setenv ( TZ = "UTC" ) df < - data . frame ( a = c ( 0 , 1 , NA , - Inf , Inf ) , b = c ( "a" , "b" , NA , "c" , "" ) , c = c ( as . Date ( "2001-01-01" ) , NA , - 99 , 0 , 1 ) , d = c ( as . POSIXct ( "2001-01-01" ) , NA , - 99 , 0 , 1 ) , arc . write ( "date.gdb/with_date" ) ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ With that, I get two date columns, "c" and "d", which contain values I would expect.

If you're just performing an aspatial join (based on a shared column), you can use the default `merge` method from R to join, see for example this post. Since you have ArcGIS available, you may also want to perform this beforehand, you can use Join Field, including via ArcPy.

Thank you Dan Patterson‌ Joshua Bixby‌ Luke Webb I did two different approaches and both worked. Approach 1. I first got a max for the selection, then switched the selection and got a second max, then took max of the both. I felt it was slow, but it works and this switching also updated my labels in display, which kind of confirmed the display of new max assigned to the features. Approach 2. I did not follow the advice of giving a hard coded path, because user can have the file anywhere on the system. So instead, I used layer.dataSource to get the path. Then I used np.amax to get the max of the array (attribute table). So broadly I followed the advice of path and the advice of np.array and also liked the list comprehension technique by Joshua. that also works.

Yes, I did this already with geometric network. But nice to know about doing the same with service area solver. Thank you.

Write %n% in the end of the path of model1 output . to prevent overwrite.

Maximum width is the maximum distance for parallel lines in the same road (roads width) That tool will make center line . note: may be you have two parallel roads and the distance between them lower than maximum value that you input, so the tool will draw a center line between two roads. and of course you don't want that. So maximum value should to be Equal to maximum road width and Lower than the distance between two roads. Minimum width is to define the distance that tool will ignore any parallel lines lower than that value.

You can write a Map Algebra Con statement (e.g. "if this, then that, else (if this, then that, else (if this, then that, else leave alone)))").

Hi Srirama, Using model builder would a good and simple approach to accomplish this task. Use Extract values to points tool in model. Your model would look like this.

Hi, i am trying to transfer an arcgis 10 personal geodatabase with a topology defined feature set to a colleague who is using arcgis 9.3.1. he is unable to open the .mdb and gets a "failed to connect database" what is the best way to transfer this file so that the topology rules are intact ? regards,
