In 2006, Monroe County flew a LiDAR elevation model for various utility or transportation improvement projects. Until a few years ago, most of this data was only available to the GIS group. The problem is, while ArcGIS can handle the size of the data, most of our consultants could not, so we came up with a workflow to help them use the data.
A presentation about this was given at the Esri Users Group Conference. The presentation is linked here. The presentation displays the methodogogy neede to use LiDAR within ArcGIS.
