OTB.VectorClassifier: Performs a classification of the input vector data according to a model file.

{"id": "OTB.VectorClassifier", "title": "Performs a classification of the input vector data according to a model file.", "description": "This application performs a vector data classification based on a model file produced by the TrainVectorClassifier application.Features of the vector data output will contain the class labels decided by the classifier (maximal class label = 65535). There are two modes: 1) Update mode: add of the 'cfield' field containing the predicted class in the input file. 2) Write mode: copies the existing fields of the input file in the output file and add the 'cfield' field containing the predicted class. If you have declared the output file, the write mode applies. Otherwise, the input file update mode will be applied.", "version": "1.0.0", "jobControlOptions": ["sync-execute", "async-execute", "dismiss"], "outputTransmission": ["value", "reference"], "links": [{"rel": "http://www.opengis.net/def/rel/ogc/1.0/execute", "type": "application/json", "title": "Execute End Point", "href": "http://demo.mapmint.com/ogc-api/processes/OTB.VectorClassifier/execution"}, {"rel": "alternate", "type": "text/html", "title": "Execute End Point", "href": "http://demo.mapmint.com/ogc-api/processes/OTB.VectorClassifier/execution.html"}], "inputs": {"in": {"title": "The input vector data file to classify.", "description": "The input vector data file to classify.", "extended-schema": {"oneOf": [{"allOf": [{"$ref": "http://zoo-project.org/dl/link.json"}, {"type": "object", "properties": {"type": {"enum": ["text/xml", "application/vnd.google-earth.kml+xml", "application/json", "application/zip"]}}}]}, {"type": "object", "required": ["value"], "properties": {"value": {"oneOf": [{"type": "string", "contentEncoding": "utf-8", "contentMediaType": "text/xml"}, {"type": "string", "contentEncoding": "utf-8", "contentMediaType": "application/vnd.google-earth.kml+xml"}, {"type": "object"}, {"type": "string", "contentEncoding": "base64", "contentMediaType": "application/zip"}]}}}]}, "schema": {"oneOf": [{"type": "string", "contentEncoding": "utf-8", "contentMediaType": "text/xml"}, {"type": "string", "contentEncoding": "utf-8", "contentMediaType": "application/vnd.google-earth.kml+xml"}, {"type": "object"}, {"type": "string", "contentEncoding": "base64", "contentMediaType": "application/zip"}]}, "id": "in"}, "instat": {"title": "A XML file containing mean and standard deviation to centerand reduce samples before classification, produced by ComputeImagesStatistics application.", "description": "A XML file containing mean and standard deviation to centerand reduce samples before classification, produced by ComputeImagesStatistics application.", "extended-schema": {"oneOf": [{"allOf": [{"$ref": "http://zoo-project.org/dl/link.json"}, {"type": "object", "properties": {"type": {"enum": ["text/xml"]}}}]}, {"type": "object", "required": ["value"], "properties": {"value": {"oneOf": [{"type": "string", "contentEncoding": "utf-8", "contentMediaType": "text/xml"}]}}}], "nullable": true}, "schema": {"oneOf": [{"type": "string", "contentEncoding": "utf-8", "contentMediaType": "text/xml"}]}, "id": "instat"}, "model": {"title": "Model file produced by TrainVectorClassifier application.", "description": "Model file produced by TrainVectorClassifier application.", "extended-schema": {"oneOf": [{"allOf": [{"$ref": "http://zoo-project.org/dl/link.json"}, {"type": "object", "properties": {"type": {"enum": ["image/tiff", "image/jpeg", "image/png"]}}}]}, {"type": "object", "required": ["value"], "properties": {"value": {"oneOf": [{"type": "string", "contentEncoding": "base64", "contentMediaType": "image/tiff"}, {"type": "string", "contentEncoding": "base64", "contentMediaType": "image/jpeg"}, {"type": "string", "contentEncoding": "base64", "contentMediaType": "image/png"}]}}}]}, "schema": {"oneOf": [{"type": "string", "contentEncoding": "base64", "contentMediaType": "image/tiff"}, {"type": "string", "contentEncoding": "base64", "contentMediaType": "image/jpeg"}, {"type": "string", "contentEncoding": "base64", "contentMediaType": "image/png"}]}, "id": "model"}, "cfield": {"title": "Field containing the predicted class.Only geometries with this field available will be taken into account.The field is added either in the input file (if 'out' off) or in the output file.Caution, the 'cfield' must not exist in the input file if you are updating the file.", "description": "Field containing the predicted class.Only geometries with this field available will be taken into account.The field is added either in the input file (if 'out' off) or in the output file.Caution, the 'cfield' must not exist in the input file if you are updating the file.", "schema": {"type": "string", "default": "Any value"}, "id": "cfield"}, "feat": {"title": "List of field names in the input vector data used as features for training.
