how to use create space time cube tool

Hi, I am using the "Space Time Cube" tool, and get the below error message. I wonder would anyone know and place help with this problem.

Thanks!

that output location is really 'difficult'... why don't you try a simpler, like in c:\test Try to avoid the Users... folder, folders with spaces and certainly the desktop. Also if this is the second time that you tried it,the error may indicate that the file already exists and clicking on the X will reveal more details.

Thanks, Dan. That works. But now the problem becomes that when I tried to select a time field, it does not show any option for me to click.

well that probably means that you don't have a field with a 'Date' type.Perhaps you need to go through the production procedure to ensure that you have the data structured properly. The format is quite specific and sometimes people assume that the STC will apply to their data when in fact, it doesn't.

Good luck

I have year, month, and date information coded in separate column...I checked the required time field info, but not clear whether or not I need to have year/month/date in the same column?

I suspect they are string/text fields and not a proper Date field... chec the column properties

Thanks, Dan. I just checked: it is a double.

The field containing the date and time (timestamp) for each point. This field must be of type Date.

from the link I sent... so you now have to create a proper Date from what you have...

what is it you are trying to do by the way? If you want to work with n-dimensional data, then this isn't the only option, I work with it all the time, using NumPy, SciPy and their brethren. May not have the cool graphics, but you can emulate just about anything you want with those and matplotlib or other graphics interfaces. This can all be accomplished and accompanied with ArcMap and/or Pro. I have blogged about NumPy and array data in general extensively.

Hi Dan, thank you. Yes, I am working on a n-dimensional data, including country and location (i.e., latitude/longitude) where each conflict event occurred as well as time (year, month, and date) each event happened. What I would like to do is to run the emerging hot spot tool for my conflict data. To do that, I have to implement the "create space time cube" tool.

So, in my case, would you suggest me to try other options (you mentioned above) or stick with the ArcGIS?

Again, thank you.

stick with STC if you are wanting to go the emerging hotspot route. It looks like you are working with nominal/categorical attributedata so you will be fine.

Thank you, Dan.

So should I use the " Select Layer By Attribute tool" to create a proper Date ? I do not see any link you mentioned you sent though.

I moved this thread to https://community.esri.com/community/gis/analysis/geoprocessing?sr=search&searchId=bd43ba59-5d09-44dc-b24b-971e5214559b&searchIndex=0‌ ..

Maybe some of the other thread observers could make some suggestions as to a better place or more resources for Yi-Jyun... other the quick demos with perfect data there is little else for users to go by.
