csv format line requirement

GUOMEILING

Hello everyone, I would like to ask a question. I need a csv format line data when conducting GA big data analysis. Does arcgis enterprise big data support csv line data? If it is supported, what are the requirements of the header field and what is the format?

Hi Guo,

CSV files are supported for big data file shares. You will just need a header, which will represent your field names. Take a look at the following help document about formatting the folder structure:

Hi guomimi‌,

A bit more information (and some questions) in addition to jskinner-esristaff‌'s reply.

GeoAnalytics supports points, lines, polygons and tables formats for big data file shares. There isn't a strict requirement for the headers, but the headers are used when you generate the manifest to try and automatically determine which fields represent geometry and/or time. So if you want to add a header, I would recommend a single row, name it with headings that makes sense, don't have a space in the header names, and if you have time or geometry fields name them time or geometry.

When you register the manifest GeoAnalytics will do a best guess to figure out the geometry field and format. If you have something a bit more complex, you may need to edit the manifest yourself.

What version of Enterprise are you using, and how are you line geometries stored in the CSV? WKT? something else?

Looking forward to seeing how that goes,

I'm sorry, probably I didn't describe it clearly.I know that GeoAnalytics supports dot-lines and tables, I mean the title of the csv format that represents line data or polygon data. Please see attachment csv format about region data

you have the geometry highlighted in black for Lake Onega

but I suspect that isn't what you are looking for either

Hi GUO MEILING‌,

That csv should work as is. When you register the big data file share, the generation process will identify the field as the geometry, because it's labelled as "Geometry" in your table. Is that not working for you?

If it's not, can you please confirm your folder structure of the datasets in your big data file share? And what the manifest for this dataset looks like.

With that information, we can figure out if there is a problem.

Thanks,

Sarah

I have a csv of point，it woks.This is a csv of polygon，It didn't woks.so I guess if there is a problem with the header？

Perhaps our way of thinking is not the same as the form of presentation, so I feel that we have had some difficulties in communication. But still thank you very much for your patience.

Hi GUO MEILING‌,

Yes, lines are supported through CSV. If you are unable to get this to work, please contact support services and they can help troubleshoot that the problem is.

Thanks,
