Spatial reference does not exist in the data source

[hanakohinonn]

• Hi, Now I have a polygon layer, and I want to convert it to raster.

So, I tried to polygon to raster, however, the error came up with.

ERORR:999999

Spatial reference does not exist in the data source.

I have no ideal to solve this problem, please help me.

Thanks in advance.

You need to define its coordinate system first 

Define Projection (Data Management)—ArcGIS Pro | Documentation

If you don't know what to define it as,

then don't guess, .... should be, could be, might be...

aren't good options, a misdefined coordinate system will only make a situation worse.

Hi, Dan. Thank you for your replying!

Following your advice, I tried define projection. And I got new error.

EROOR:999999

Table name is not correct.

Table is not found. 

How do you think why I cannot complete [define projection] and [polygon to raster]?

Any ideal would be help me.

Thank you.

something is wrong with the file. 

Can you add it all by itself to a map and view it? (no basemap, no other data)

Can you open the table?

What are the extents of the file (left, right, top bottom)? check under the layer properties.

What Is the coordinate system supposed to be in light of the extent?  Does it look like decimal degree data? or does it look like it is projected?

also try running CheckGeometry

Hi, Steve. Thank you for your replying!

I tried CheckGeometry, but I failed to it.

I don’t know  what is the reason.

If you have any idea, please teach me.

Thank you.

Your polygon layer, is it from a shapefile or a file geodatabase?
Right click the layer to see the properties.
Provide a screenshot showing the map and could you share the data.

[SteveLynch]

can you use CopyFeatures and copy it into the default file geodatabase and then try using the copied feature class.

[hanakohinonn]

Thank you for your advice!

I tried Copy Features ,but it also failed.

I  have no idea  why my shapefile cause a lot of error.  Are  there any solutions?

[DanPatterson]

What was the actual error?

Did you get the shapefile from somewhere? or did you produce it?  

Did you get any errors when loading the shapefile into a blank map?

If Repair Geometry and Copy Features doesn't fix the geometry problems there is little else you can do.
