PointSampleOperator.AttributeName Property
Gets or sets the AttributeVariable<Atom> that controls what attributes are used for sampled values.
Syntax
public AttributeVariable< Atom > AttributeName { get; set; }Property Value
Default: value
An AttributeVariable<Atom>
Remarks
When the raster is sampled and a feature is created, this property will be evaluated into an attribute name used to store the sampled value in the created point feature.
If there are multiple rasters in the location of a sample point, you can use this property to store values from different rasters in different attributes. This is especially useful if your data is split up in different rasters over the same area and need to be combined to be usable. An example of this is when each cell represents a vector. It might be divided into two rasters where one contains the X value and the other raster contains the Y value.
A typical way is to use the KeyedAttributeVariable<Atom> where the key is some attribute on the raster that will tell you what kind of data it contains. The value can then be set to a name relevant to what the key represents, such as elevation or the type of terrain.
If a sample point samples multiple rasters where the attribute name is evaluated to the same name, the value stored in the feature will be overwritten with the last sampled value.
