Agenda

• Introduction of Cache Map Services

• Publish Image service on ArcGIS server

• Discuss caching methods, workflows, best practices

• Question & Answer session

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?

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.

Software ArcGIS Desktop 10.3 ArcGIS Server 10.3 with Image Server extension

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.

• Advantages • Reduce processing time and storage. • Catalog large image collection • Seamless display at all scales • Multiple sensors and metadata

Mosaic Dataset

Authored from Desktop , Publish to ArcGIS Server

• Using Geo processing tool • ArcGIS Editor license • ArcGIS Server Image Extension

Publish Imagery on ArcGIS Server

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
