Reverse Geocoding

Uses a reference polyline (street centerlines) layer to assign addresses to the points from a point layer. Allows transfer of any additional attributes.

Inputs:

A point layer which features are to be assigned addresses
A reference polyline layer that will be used as a source for the addresses
The type of address data
- Single
- Range Continuous - From and To address fields expected
- Range Address - Two pairs (Left & Right) address fields expected. The side of the points taken into account.
Search distance
Additional fields to be transferred to the points
Keep Input Spatial Reference - If selected the output will have the spatial reference of the input dataset, else the spatial reference of the reference dataset will be used

Outputs:

A point feature class with addresses assigned to the points

Notes:

Range attributes fields should be numeric fields.
The units of the Search Tolerance should be the units of spatial reference of the input dataset if the user has selected the Keep Source Spatial Reference option. Otherwise - the units of spatial reference of the reference dataset.
The Source and the Snap datasets can have different spatial references as long as they have the same Geographic Coordinate systems.

Example:

Parameters

Expression	Explanation
Function Name	ReverseGeocoding
<input dataset>	A String representing the input layer. Must be of Point type.
<reference dataset>	A String representing the reference layer. Must be of Polyline type
<output dataset>	A String - the full name of the output layer.
<search tolerance>	A Double representing the Search tolerance to be used. The units of the tolerance are the units of spatial reference of the input dataset if KeepSourceSref = TRUE. Otherwise - the units of spatial reference of the reference dataset.
<Type>	A String indicating the type of address data - valid values - Single, Continuous, Address
{LeftFromField}	A String representing a field name in the Reference dataset source for the start address on the left side of the road. If the type is Continuous - the start address
{LeftToField}	A String representing a field name in the Reference dataset source for the end address on the left side of the road. If the type is Continuous - the end address
{RightFromField}	A String representing a field name in the Reference dataset source for the start address on the right side of the road. If the type is Continuous not used.
{RightToField}	A String representing a field name in the Reference dataset source for the end address on the right side of the road. If the type is Continuous not used.
{AdditionalFields}	A String representing a list of additional field names which values will be transferred to the points - separator - semi-colon (;) - Example: "field1; field2; ...."
{KeepSourceSref}	A Boolean indicating whether the output to have the spatial reference of the input layer. If False or 0, the spatial reference of the reference layer will be used.

Running the function

ETGWPath used in the table below is the full path to ETGWRun.exe (E.G. "C:\Program Files\ETSpatial Techniques\ETGeo Wizards\ETGWRun.exe")

Language	Syntax
Python	subprocess.call([ETGWPath, "ReverseGeocoding", "input dataset", "reference dataset", "output dataset", "search tolerance", "Type", "LeftFromField", "LeftToField", "RightFromField", "RightToField", "AdditionalFields", "KeepSourceSref"])
.NET using ETGWRun.exe	StartInfo.FileName = ETGWPath StartInfo.Arguments = "ReverseGeocoding" "input dataset" "reference dataset" "output dataset" "search tolerance" Type" "LeftFromField" "LeftToField" "RightFromField" "RightToField" "AdditionalFields" "KeepSourceSref"
.NET using ETGWOutX.dll	ReverseGeocoding(input dataset,reference dataset, output dataset, search tolerance, Type, LeftFromField, LeftToField, RightFromField, RightToField, AdditionalFields, KeepSourceSref)
ArcPy	arcpy.ReverseGeocoding(input dataset, reference dataset, output dataset, "search tolerance", "Type", "LeftFromField", "LeftToField", "RightFromField", "RightToField", "AdditionalFields", "KeepSourceSref")

Notes:

<> - required parameter
{} - optional parameter
See examples for Python , .NET or ArcPy
The argument separator for StartInfo.Arguments is space. If a string might contain a space, you need to double quote it.
