DfadDataSet Class
A dataset for reading databases according to the DFAD standard, MIL-PRF-89005.
NuGet/Assembly: Carmenta.Engine.5.16.2.nupkg (in the CEDataSets assembly)
Syntax
public class DfadDataSet : MultiFileDataSetRemarks
This dataset reads databases according to the DFAD standard.
The dataset reads point, line and polygon features with associated attributes. For a thorough description of the attributes, see the standard documentation MIL-PRF-89005.
Four attributes are common for all objects:
Attribute name | Type | Description |
|---|---|---|
FAC | Integer | Feature Analysis Code - object id within this file. |
FID | Integer | Feature Identification Code - a code that describes what this object is. |
RSF | Integer | Radar Significance Factor - a measure of how good this object reflects radar waves. |
height | Integer | Height relative to ground. |
These attributes are always set on features from a DfadDataSet. Other attributes are specific for different types of features.
Points have the following attributes:
Attribute name | Type | Description |
|---|---|---|
orientation | Double | Direction for object. orientation > 360 means omnidirectional. |
length | Integer | Length of object. |
width | Integer | Width of object. |
Lines have the following attributes:
Attribute name | Type | Description |
|---|---|---|
direction | Integer | Defines what sides of the line that reflect radar waves. |
width | Integer | Width of line. |
Polygons have the following attributes:
Attribute name | Type | Description |
|---|---|---|
numStructuresCode | Integer | Code for number of buildings per square kilometer. |
roofCoverage | Integer | Percentage of the surface that is covered by roofs. |
treeCoverage | Integer | Percentage of the surface that is covered by trees. |
