Error: The Geometry has no Z values

The Geometry has no Z values error occurred when adding map annotation to ArcGis.

The solution is as follows:

 

Public bool AddFeature (ESRI. ArcGIS. Geometry. IGeometry geometry, System. Collections. Generic. Dictionary <string, object> properties)

{

Try

{

ESRI. ArcGIS. Geodatabase. IFeature feature = _ featureLayer. FeatureClass. CreateFeature ();

 

Int index;

Index = feature. Fields. FindField ("Shape ");

IGeometryDef pGeometryDef;

PGeometryDef = feature. Fields. get_Field (index). GeometryDef as IGeometryDef;

 

If (pGeometryDef. HasZ)

{

IZAware pZAware = (IZAware) geometry;

PZAware. ZAware = true;

// IZ iz1 = (IZ) geometry;

// Iz1.SetConstantZ (0); // set the Z value to 0

IPoint point = (IPoint) geometry;

Point. Z = 0;

}

Else

{

IZAware pZAware = (IZAware) geometry;

PZAware. ZAware = false;

}

If (pGeometryDef. HasM)

{

IMAware pMAware = (IMAware) geometry;

PMAware. MAware = true;

}

Else

{

IMAware pMAware = (IMAware) geometry;

PMAware. MAware = false;

}

 

 

Feature. Shape = geometry;

Foreach (string key in properties. Keys)

{

SetFeatueProperty (feature, key, properties [key]);

}

Feature. Store ();

Return true;

}

Catch (Exception ee)

{

Return false;

}

}

How to convert Gemetry without Z value into Geomtry with Z value in Engine: error "the geometry has no Z values"

15:19:39 | category: GIS development | font size subscription

When you use Feedback to create a new element, the obtained element does not have a Z value. If the data source (Layer Element) has a Z value, the new element fails. the error "the geometry has no Z values" is returned ". You can use the following methods to solve the problem:

// First determine whether the layer element has the Z value int index; index = pFeature. fields. findField ("Shape"); IGeometryDef pGeometryDef; pGeometryDef = pFeature. fields. get_Field (index ). geometryDef as IGeometryDef; IPointCollection pPointCollection = pgom as IPointCollection; if (pGeometryDef. hasZ) {IZAware pZAware = (IZAware) pgom; pZAware. ZAware = true; IZ iz1 = (IZ) pGeom; iz1.SetConstantZ (0); // set the Z value to 0} else {IZAware pZAware = (IZAware) pGeom; pZAware. ZAware = false;} if (pGeometryDef. hasM) {IMAware pMAware = (IMAware) pgom; pMAware. MAware = true;} else {IMAware pMAware = (IMAware) pgom; pMAware. MAware = false ;}

(Conversion) if the data source does not have the Z value but the target data source has the Z value, set. shape = B. an error occurs during Shape.

The solution is to use FME to convert data sources without element classes. The default Z value is zero. The disadvantage of this method is the trouble.

Can't I use the Engine to convert rows? Yes. However, if you directly obtain the Geometry of the data source and then forcibly assign the Z value to it (IZWare = True is not acceptable), you need to create a New Geometry Based on the Geometry of the data source, then, assign the Z value to each node.

Pay attention to two issues: when you use the Geoemtry node of the cyclic data source, you must note that the temporary variable must be long. Generally, dim I as integer is preferred, but many node data may exceed 30 thousand :)

The second issue to be noted is that the data source may be composed of multiple components, polyline may have multiple paths, and polygon may have multiple rings, take a good look at the modry Modal PDF file. If the data source has only one part, you can traverse all pointcollection's point and assign the Z value. If there are multiple parts, you will know a little experienced, this is not the case. Oh, you need to create a part.

When cutting elements, if the elements have a Z value, the same is true.
