Local Government Needs
• Store and manage Imagery/LiDAR
• Disseminate as a basemap (web, desktop)
• Imagery/LiDAR distribution
• Serve to CAD or Non-GIS clients
• Feature creation/update
• Historical analysis and management
• Image Analysis (impervious surface mapping, image
classification)
• Image processing
![Page 3: PowerPoint Presentation · Title: PowerPoint Presentation Author: Kevin Armstrong Created Date: 4/10/2013 1:13:06 PM](https://reader035.vdocuments.net/reader035/viewer/2022081616/5fff0b591cfa93145a40a978/html5/thumbnails/3.jpg)
Local Government Concerns
• Cost of Image Acquisition
• Lack of Storage Space
• Performance
• Public Requests
• Requests from other Gov’t entities
• Historical imagery request, processing and
management

What is a Mosaic Dataset?
• Catalog of
- Imagery
- Associated metadata
- Processing functions to be applied
• Stored in Geodatabase
• Authored using ArcGIS for Desktop
• Enables
- Dynamic Mosaicking
- On-the-fly processing

Demonstration
Creating a Mosaic Dataset
![Page 7: PowerPoint Presentation · Title: PowerPoint Presentation Author: Kevin Armstrong Created Date: 4/10/2013 1:13:06 PM](https://reader035.vdocuments.net/reader035/viewer/2022081616/5fff0b591cfa93145a40a978/html5/thumbnails/7.jpg)
Serving Imagery
2 Ways to Serve Imagery
• Directly from individual raster dataset
• From mosaic dataset (requires image extension)

On-The-Fly Processing
Creating Multiple Products from a Single Source
• Processes
• Extract Bands
• Hillshade, Shaded Relief
• Stretch
• Applied to
• Individual rasters
• Compete Mosaic
