Vector Data validation¶

Vector data validation based on the fusion of features using Dempster-Shafer evidence theory framework.

Detailed description¶

This application validates or unvalidate the studied samples using the Dempster-Shafer theory.

Parameters¶

This section describes in details the parameters available for this application. Table [1] presents a summary of these parameters and the parameters keys to be used in command-line and programming languages. Application key is VectorDataDSValidation .

[1]	Table: Parameters table for Vector Data validation.

Parameter Key	Parameter Type	Parameter Description
in	Input vector data	Input vector data
descmod	Input File name	Input File name
belsup	String list	String list
plasup	String list	String list
cri	String	String
thd	Float	Float
out	Output vector data	Output vector data
inxml	XML input parameters file	XML input parameters file
outxml	XML output parameters file	XML output parameters file

Input Vector Data: Input vector data to validate.
Descriptors model filename: Fuzzy descriptors model (xml file).
Belief Support: Dempster Shafer study hypothesis to compute belief.
Plausibility Support: Dempster Shafer study hypothesis to compute plausibility.
Criterion: Dempster Shafer criterion (by default (belief+plausibility)/2).
Criterion threshold: Criterion threshold (default 0.5).
Output Vector Data: Output VectorData containing only the validated samples.
Load otb application from xml file: Load otb application from xml file.
Save otb application to xml file: Save otb application to xml file.

Example¶

To run this example in command-line, use the following:

otbcli_VectorDataDSValidation -in cdbTvComputePolylineFeatureFromImage_LI_NOBUIL_gt.shp -belsup cdbTvComputePolylineFeatureFromImage_LI_NOBUIL_gt.shp -descmod DSFuzzyModel.xml -out VectorDataDSValidation.shp

To run this example from Python, use the following code snippet:

#!/usr/bin/python

# Import the otb applications package
import otbApplication

# The following line creates an instance of the VectorDataDSValidation application
VectorDataDSValidation = otbApplication.Registry.CreateApplication("VectorDataDSValidation")

# The following lines set all the application parameters:
VectorDataDSValidation.SetParameterString("in", "cdbTvComputePolylineFeatureFromImage_LI_NOBUIL_gt.shp")

VectorDataDSValidation.SetParameterStringList("belsup", ['cdbTvComputePolylineFeatureFromImage_LI_NOBUIL_gt.shp'])

VectorDataDSValidation.SetParameterString("descmod", "DSFuzzyModel.xml")

VectorDataDSValidation.SetParameterString("out", "VectorDataDSValidation.shp")

# The following line execute the application
VectorDataDSValidation.ExecuteAndWriteOutput()

Limitations¶

None.
