HI I have a point layer where multiple points overlap. For example, lets take 3 points at the same location. Each point has an attribute X with some number value (integer). What I want to do is, summarize that location. Meaning have only one point at that location instead of 3, and this one resulting point should get the maximum value of the 3 overlapping points. thank you,

Hi All, I am having transit lines of a city. Many of them overlap as they come into the city center. I want to measure the overlap (length along the same physical geometry) in km for example. As you may imagine, the stretch of overlap will be very different for different routes. So if I can somehow measure that, 5 routes use 3.4 km of overlap, 2 routes use 5km of overlap etc, that will be very useful. Any idea would be of great help Thank you, Ram

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

Hi, how do I convert a as.Date of R to a Date in ArcGIS? The field is a date in the r data.frame, but when it is opened in arcgis, it is a character/ string type. thank you.

Hi I would like to do a one-to-many join from within R. I have an shapefile with N features. I have a table with 12xN records. I would like to join the shapefile with the table so that there is a one-to-many relationship. It is possible to write in R script, to join my table to a shapefile? I am unable to find ways to join data table as one-to-many. Any guidance please. thank you

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.

would your solution of accessing a disk file be affected by: 1. lock imposed by arcmap 2. hard-coded path on the file system?

User selects few features, sets their income to max(income in whole of fc) +1 , so now the max of income of whole fc has changed. User goes to another area in the extent, selects a few polygons, sets their income to max(income in whole of fc) + 1, so the max of income in the whole fc has changed again. This continues till all polygons are finished.

Thank you, may be I was not clear. Your code gives same answer as mine. Let me try again. Imagine you have 3 features [0,1,2] in a fc. They have a income field which is an integer [10,12,14] respectively . case1: I have selected no feature selected, I ask for max of fc , I get 14 >> correct case2: I have selected features [0,1], i ask for max of fc , I get 12 >> incorrect, I still want 14, because I am asking max of fc, not max of selection of fc. case3: I have selected features [1,2], i ask for max of fc, I get 14, >> correct I hope it clarifies a bit?

Hi I would like to get the maximum of a field in a feature class. If no features are selected, I get the right value. But if some features are selected, I am getting the maximum of a field from within these selected features. However, I would like to get maximum of a field from the whole table i.e., from both selected and un-selected features. how may I do it? Thank you

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

I am using a street network of a large city with almost 6000 line features. When I am doing a network analysis, I get error of disconnected elements in the network. Is there any tool to identify such disconnected line segments that are not connected to any other line, or a couple of lines connected to themselves but not to the larger network. It is a large network and I am not able to visually find these. thank you.
