Agenda
• Introduction of Cache Map Services
• Publish Image service on ArcGIS server
• Discuss caching methods, workflows, best practices
• Question & Answer session
3. Cached maps are a collection of map images (tiles) organized by scale level. The
primary purpose of cached maps is that the images are pre-rendered for fast
display and reduces the load on the GIS Server.
What are Cached Maps?
4. Cache Image Service Key Steps
Designing Data
Prepare input datasets
Create File Geodatabase
Create Mosaic Dataset
Built Overviews
Publish Image service
Publish an Image Service on ArcGIS Server
Create Cache
Projection :Web Mercator Auxiliary Sphere in most cases.
Scales, extent and image format.
Tile Scheme ESRI/Google/BING
Storage –each scale requires 3-4 times storage of previous scale.
6. Designing
Mosaic Dataset
• A GDB data model for managing and serving a collection of images
• Supported in FGDB/SDE
• Do NOT store pixels but reference them.
7. • Advantages
• Reduce processing time and storage.
• Catalog large image collection
• Seamless display at all scales
• Multiple sensors and metadata
Mosaic Dataset
8. Authored from Desktop , Publish to ArcGIS Server
• Using Geo processing tool
• ArcGIS Editor license
• ArcGIS Server Image Extension
12. Cache Tile Format
• PNG
• PNG8
• PNG24
• PNG32
• JPEG
• MIXED
Storage Format
COMPACT
Group tiles into large files called bundles. This storage format is more efficient
in terms of storage and mobility. This is the default.
EXPLODED
Each tile is stored as an individual file. Note that this format cannot be used
with tile packages
