Inconsistencies in shp files

194 Views, 4 Replies

I have received shp files from a county source and am confused on the inconsistency of the Object Data. They sent me a piece of topo in a shp format and I used MAPIMPORT, then opened a new drawing, did a query, alter properties, picked the elevation, related it to the object data,  and all the contours have elevation, no problem.

They also have the zoning in shape files. However, using the same workflow as above, the object data is not there. If I use data connect and look at a property filter I can see the object data so I know in some way it is connected.

Does anyone know what causes the inconsistency between the shape files?

Also, can someone point me to a good tutorial on how to use the property filters? I would do it that way if I could figure out how to properly do a property filter.

Thanks, Tim

Short answer; you need to import as closed polygons and convert to a topology. With to object data conneced to the nodes.

There is an article in the knowlege base under suport for Map about converting SHP files into topologies.

I don't concur in it, sir.
During _MAPIMPORT operation, the only thing to check is the following one:

Here is what I am talking about. I have discovered looking at the data I have that I have more than one version of each file on the CD's. So it makes for some interesting explanation. I'll try to add the pngs in order to explain the inconsistencies. What I want to know in the end is how to explain to the county what version of this I need so I can use object data. In other words, wht are they doing when writing these to make each one different?

Zoning_Empty_sort_of.png

 

So the above version has no Object Data.

Zoning_Good.png

 

This next version above shows the object data.

Zoning_Feat_ID_only-Selectable.png

In the above version, the FeatID is selectable. When you select it, you can see the other fields.

 

zoning_selection_boxes.png

 

And finally, this version makes every Target Field Selectable, not that it matters, because each box is just a downarrow with only the selection in it.

So what is causing the difference, and how do I explain to the provider how to write the data so I get Object Data that I can query? I just want to get this knowledge written down somewhere so I can always refer to it and get the version I need to begin with rather than run in circles.

Thanks for the help!

Hi Tim,

 

The screenshots are very small but it looks to me like your provider is providing some data with attributes and some without attributes. You'll need to make sure that they send you data with attributes if you want to use the intellegence behind the geometry.
