ET GeoWizards Linear Referencing
Linear Referencing (or Dynamic Segmentation) is a very important GIS feature. In many cases (road, river management systems etc.) the data is not represented with X & Y coordinate pairs, but rather in one dimensional linear referencing system. ArcGIS has a comprehensive set of tools for creating, displaying and analyzing such data. Most of these tools however are available only to the users with ArcEditor or ArcInfo licenses.
ET GeoWizards 9.3 introduces a new set of functions that enables the ArcView license holders to perform tasks standard only in the top licensing options of ArcGIS
|ET GeoWizards Functions||Standard ArcGIS Tools|
|available with any ArcGIS license||available in|
|Create routes from existing polylines||ArcEditor and ArcInfo|
|Calibrate Routes with points||ArcEditor and ArcInfo|
|Locate point features along routes||ArcInfo|
|Locate polygon features along routes||ArcInfo|
|Dissolve Route Events||ArcInfo|
|Concatenate Route Events||ArcInfo|
|Intersect Route Events||ArcInfo|
|Union Route Events||ArcInfo|
Since the ET GeoWizards functions work in a very similar fashion to the standard tools we strongly recommend our users to read the "Linear Referencing in ArcGIS" book , provided by ESRI on the ArcGIS instillation media in pdf format. The book gives a good overview of the Linear Referencing and discusses in detail the options available.
