Introducing 'Interpolate/Extrapolate Z-Values'

With version 10.2.49 of the GP Tools, a new GP tool named ‘Interpolate/Extrapolate Z-Values’ is provided. This tool will calculate the z-values that are 0 or NaN for polyline vertices by extrapolating/interpolating the known z-values from other vertices. The tool will store a z-value of zero for vertices that cannot be calculated.

This functionality is offered for the business purpose of applying elevations to previously 2d polylines that have been Z-enabled but are not yet populated.

Z-value support for Insert Vertices

With version 10.2.48 of the GP Tools, the Insert Vertices tool has been augmented to support the application of Z-elevation coordinates onto non-colinear 2d centerlines which are z-enabled but have no Z-coordinates.

  • The tool has been modified to include a new checkbox input to allow the user to specify whether or not they want the nearest polyline vertex within the buffer to move to the point location and other vertices in within the buffer to be removed. This option is labelled as ‘Move Points within Buffer Distance’.
  • If the polyline and point sources are both z-enabled, the utility will copy the z-values from the point to the inserted vertex on the polyline when the ‘Insert’ option is selected. Note that this will occur when the ‘Move Points within Buffer Distance’ option is not checked,  of if there are no polyline vertices within the buffer distance if it is checked.
  • When the point z-values are used to populate the z-value for an inserted polyline vertex as described above, it will be factored to the appropriate units (provided both the point and polyline sources have vertical spatial references assigned to them).

Introducing 'Solve Bifurcations'

A new version (10.2.46) of our GP tools has been released.

It contains the first widespread release of the bifurcation solver as a GP Tool.  This replaces the previous bifurcation solver TAM.  All users with active maintenance during this release are encouraged to  implement the new solver - as we believe it is quicker and requires significantly fewer steps/iterations to a bifurcation free MLLRS. 

We think it is working properly – but more testing would be good, particularly with regard to curves.

Please provide feedback for any issues you might encounter.

Apostrophe char now supported in Reverse Geocoder GP Tool

A new version (10.2.45) of our GP tools has been released.

This version includes the following enhancements:

  • Modified the ‘Calculate LRS Measure Fields’ utility to work with routes that have an apostrophe in their name.

You asked -- and we responded!  Users that have exterminated the dreaded apostrophe inside a name string can now return to allowing apostrophes.

Enhancements to 'ReShape Partial Polylines'

A new version (10.2.43) of our GP tools has been released.

This version incorporates the following with regard to the ‘ReTrace Partial Polylines’ GP Tool:

  • Added an input for specifying a ‘Grouping’ field. This can be a text field that can be used to help group demarcation points sharing common route ids for the route providing the shape and the route being updated.
  • Added an input for specifying if the shape will be replaced or redacted.

NOTE: This version still uses the polyline Reshape method that was previously enhanced to make sure the polylines connected near the demarcation points. We may still need to modify this, by writing our own method to accomplish the reshape, if the results are undesirable.

Introducing 'ReTrace Partial Polylines' GP Tool

A new version (10.2.40) of our geoprocessing toolset has been released.

This version includes our first general release of the utility that was originally developed in Summer 2003 - and was the demonstrated in PowerPoint presentations beginning in 2009 when Arizona began to warm to the idea of centerline unification.

By special request, we have rushed this tool toward release - though beyond the scope of the 1st extension of the ATIS Unification - it is being delivered out of scope due to new requirements placed by ADOT ITG with regards to the Roads and Highways conversion.  

This new GP tool is named ‘ReTrace Partial Polylines’.  This tool uses pairs of demarcation points having common values in fields named ‘TargetRoute’ and ‘ReTraceRoute’ in a DemarkationPoints feature class to extract the portion of the polyline from the feature identified in the ‘TargetRoute’ field and use it to reshape the feature identified in ‘ReTraceRoute’. Note that these fields are not hardcoded in the tool (they are settable in the GP interface).  Just referring to their names as they exist in ADOT's version of the DemarkationPoints feature class.

The tool is available in the ‘Geometry’ category of ‘LRS GP Tools’.
