Supporting Imagery and Lidar in the ArcGIS platform has been around for a long time. In the ArcGIS Server Space, Image Server became available at 9.3.1. Since then it has evolved to Mosaic Datasets, Image Services, Raster Functions and now raster analytics. Now imagery is really an integral part of the ArcGIS platform. However, it is only as performant when the imagery is managed and configured optimally.
I often get asked,
- what format should I store my imagery in?,
- How many images can be in a Mosaic Dataset?
- How should I structure my imagery? and
- what is the maximum number of images per folder?
When answering these questions I have drawn on past experience and advice from Esri. Now though Esri have compiled all this information into an Excellent Centralised resource Imagery Workflows – Best Practices https://doc.arcgis.com/en/imagery/workflows/best-practices/what-are-best-practices.htm
In the Imagery formats and Performance section it details topics such as:
- File format suitability
- Recommended imagery formats
- Reformatting imagery
- Pyramids
- Statistics
- Working with large mosaics
- Storage system performance
If you’re going to be managing imagery and lidar I recommend you reads these documents. They are comprehensive and invaluable. I must admit I have been doing this for 12 years now and there is information on Lidar management that I did not know about.
This is just one component of the ArcGIS Imagery Workflows documentation Esri has just produced.
