Process Step:

Process Description:
Noise wall data was compiled in an Excel spreadsheet. The first step in the conversion to GIS data was to add an unique Id field ("ID") to the current and proposed data sets. Separate files were created for noisewalls in the increasing and decreasing directions for later use in ArcMap. Two approaches were used to get the data from Excel to ArcMap. The files for the current noisewalls were converted to dbfs. The files for the proposed noisewalls were converted to Access tables. The dbfs and Access tables were then added to ArcMap. The "Add Route Events" tool was used with the offset option to create event themes from the current and proposed, increasing and decreasing noise walls. The option "generate a field for locating errors" was used; it's found under "Add Route Events" advanced options. The current noise wall event themes were then converted to shapefiles and merged, and the proposed noise wall event themes were converted to feature classes and merged.
