Make xy event layer issues 10.1

KevinGledhill — Wed, 24 Jul 2013 12:03:52 GMT

I have a table with some lat/long values, and am simply trying to create an xy event layer from them. No matter what I do (format, projections, etc) they points will not create in the correct lat/long location. I believe it's a 10.1 issue, and maybe bug, since I sent the data to a friend with 10.0 and he had no trouble what so ever. I even followed his exact steps.

Are there known issues with the xy event tool in 10.1? Or any suggestions/pre processing I could do to make this work?

Thanks,

Kevin

Hi Kevin,

Can you upload the table you are working with, or post a sample?

Having the same problem at a fully patched ArcGIS 10.2.2 Standard w/64bit background geoprocessing on Windows 7 Pro 64bit SP1

The attached image displays a point "Identify." Notice the Lat_DD and Lon_DD attributes (used to create the points) do not match the "Location" values.

The attached File Geodatabase (zipped into a single file) contains two tables:

GCP_Table - Used the Lat_DD and Lon_DD fields to create the XY layer.
CreatedByMakeXY - Notice the XY Coordinate system is set to what I used to create the event layer

BTW - Same results using ArcGIS 10.0

Is this enough information? Thank you

Hi Bruce,

I didn't see an attachment. Can you try uploading it again?

Still no attachments. Try starting a new thread and then uploading your zip file.

The attachments are there and are downloadable from my message(s).

Maybe site privileges or some other geonet settings are not allowing you to seem them. I'm checking into that possibility.

Bruce,

The properties page of your layer indicates that you created the points using state plane (feet), NOT degrees decimal.

I think that might be a bit of a problem.

When you load a table into make XY events, you have to specify the correct XY columns & what the numbers in those columns represent, ie the correct coordinate system.

Choosing "WGS 1984" (as given by Jake Skinner) from "Geographic Coordinate Systems/World" seems to have corrected the problem. The points are now in the proper locations.

The information below was given for the points, so I assumed they should be created using the "projection"

Coordinate System: US State Plane 1983 (US survey feet)
Datum: NAD 83(NA2011)
Zone: Illinois West 1202
Geoid: GEOID12A (Conus)
Vertical Datum: NAVD88

So, from the information given, what told you I should use WGS 1984? My guess is because Lat/Long values were used indicating "world coordinates"!?!

Thank you Jake and Neil

Yes, since the lat/long values were in the format they were in. State Plane coordinates would be a 6 digit and 7 digit coordinate. Ex: 237219.09, 2693160.81

Bruce, if you look at your table there are several columns given the coordinates in different formats.

The "Easting" and "Northing" columns appears to be State plane feet. So if you had used these in the MakeXYEvents, the points would have been created directly in the stateplane projected system.

LONG_DD & LAT_DD are exactly what they call themselves, Lat/Long degrees decimal.

Hi Neil,

Thanks for keeping on top of this. After your last reply, I wondered if the easting and northing values pertained to the State Plane coordinates - tried it and it worked perfectly.

So it turns out I didn't have to create the LONG_DD/LAT_DD values after all - silly me, but that's how we learn.

Thanks again.
