Projection Error

Atom

Hi, 

 

Does anyone know how to solve this error? I am inputting a shapefile from ArcMap into Alteryx, i have 3 shapefiles and only one of them is showing this error. I have tried to reproject my shapefile in Arc with little success.

 

Error: Input Data (18): No available conversion between projections.

Source is:

PROJCS["WGS_1984_Web_Mercator_Auxiliary_Sphere",GEOGCS["GCS_WGS_1984",DATUM["D_WGS_1984",SPHEROID["WGS_1984",6378137.0,298.257223563]],PRIMEM["Greenwich",0.0],UNIT["Degree",0.017453292519943295]],PROJECTION["Mercator_Auxiliary_Sphere"],PARAMETER["False_Easting",0.0],PARAMETER["False_Northing",0.0],PARAMETER["Central_Meridian",0.0],PARAMETER["Standard_Parallel_1",0.0],PARAMETER["Auxiliary_Sphere_Type",0.0],UNIT["Meter",1.0]]

Target is:

GEOGCS["GCS_WGS_1984",DATUM["D_WGS_1984",SPHEROID["WGS_1984",6378137,298.257223563]],PRIMEM["Greenwich",0],UNIT["Degree",0.017453292519943295]]

Are the other shapefiles in the same projection?

 

I'd try changing your ArcMap view to be in the standard geographic coordinate system (View in the menu, then Data Frame Properties, select WGS1984). Then right-click on each layer and select Data->Export Data... Choose "Use the same coordinate system as: the data frame". This will put all the data sets into the same projection and recreate the shapefiles to ensure there is no corruption. Alteryx should have no problem with WGS1984.

Hi Philip,

 

At the moment all of our shapefiles when you select properties and source say

 

Data Type:               Shapefile Feature Class

Shapefile:                Z:\Retail Consultancy\Projects\Argent\10 Updated Project (April 2018)\03 Mapping\Argent Retail Units.shp

Geometry Type:      Polygon

Coordinates have Z values:     No

Coordinates have measures:  No

 

Geographic Coordinate System:             GCS_WGS_1984

Datum:    D_WGS_1984

Prime Meridian:      Greenwich

Angular Unit:          Degree

 

 

Whereas the one file that Alteryx can’t read says

 

Data Type:               Shapefile Feature Class

Shapefile:                Z:\Retail Consultancy\Projects\Argent\10 Updated Project (April 2018)\03 Mapping\Argent_Retail_Units_Yard_Level.shp

Geometry Type:      Polygon

Coordinates have Z values:     No

Coordinates have measures:  No

 

Projected Coordinate System:                WGS_1984_Web_Mercator_Auxiliary_Sphere

Projection:               Mercator_Auxiliary_Sphere

False_Easting:        0.00000000

False_Northing:      0.00000000

Central_Meridian:   0.00000000

Standard_Parallel_1:              0.00000000

Auxiliary_Sphere_Type:          0.00000000

Linear Unit:             Meter

 

Geographic Coordinate System:             GCS_WGS_1984

Datum:    D_WGS_1984

Prime Meridian:      Greenwich

Angular Unit:          Degree

 

Do you know why this is, all of the shapefiles have been made and are very similar.

I've had trouble before with shapefiles in a Web Mercator projection. It isn't always recognized by the projection transformation engine. Have you tried reprojecting it to match the others? I'd try changing the ArcGIS view to match those others, then following the above to create a new shapefile in the projection to match the others. You could also try the reproject tool, but move it out of Web Mercator some way.

This has worked thank you for your help.
