Terminology
• Raster format – defines how pixels are stored
- Ex. TIFF, MrSID, ECW, CRF
• Raster type – defines the metadata to be read and used for processing
- Ex. Raster Dataset, IKONOS, Table
• Raster function – on-the-fly processing of pixels
- Ex. NDVI
• Mosaic dataset – data model in a geodatabase for managing imagery
• Image service – data model for accessing mosaic datasets as a web service

What is a Mosaic Dataset?
• A Catalog:
- References Imagery
- Associated metadata
- Processing functions can be applied
• Stored in Geodatabase
• Created using ArcGIS for Desktop
• Provides:
- Dynamic Mosaicking
- On-the-fly processing
ArcGIS Imagery Information Model
Highly scalable… from small to large volumes of imagery
Creating a Mosaic Dataset in ArcGIS Pro
1. Create Geodatabase (File or Enterprise)
2. Create Mosaic Dataset
3. Add Rasters
4. Generate Overviews (optional)
A brief summary
Add Rasters
• Specify parameters
• Crawls for imagery according
to the raster type
• Defines the initial processing
Adding data to your mosaic dataset
Supported Imagery
• Format: TIFF, JPEG, JPEG 2000, MRF, CRF, IMAGINE, NITF, netCDF, HDR, GRIB,
MrSID…
• Data Structure: Bands, Bits, Tiling, Pyramids, NoData
• Compression: Lossless, Lossy, Limited Error
• Georeferencing: Spatial reference systems
• Metadata: Acquisition Date, Color Map, Source, Copyright, Band wavelengths
Supports over 50 sensor types!
Overviews
• Like pyramids for a Mosaic Dataset
• Used for faster display at smaller scales (when zoomed out)
• Optional - if not created, imagery may not appear when zoomed out
• May also consider adding smaller scale imagery
Why can’t I see my data?

Creating and
Configuring a
Mosaic Dataset
Mosaic Dataset Properties
• General
- General properties relating to
the data structure (number of
bands, bit depth)
- Source Type: Generic →Processed
• Defaults
- Direct the use of a Mosaic
Dataset when Published
- Sets some limits on Publishing
From the Catalog Pane
Mosaic Dataset Processing
• Initial Raster Function Chain defined by Raster Type
• Apply additional processing
a) To items in mosaic dataset
b) By adding to raster function
chain
c) By attaching to mosaic dataset
• Persists when shared
For easy and efficient visualization and exploration
What are Raster Functions?
Operations that apply processing directly to
the pixels of imagery and raster datasets
• No new dataset created
• Fast and efficient; processing on-the-fly
• Easily view and edit raster function history
• Create and use custom raster functions
• Save sets of raster functions as templates
• String processes together for complex
modeling
• Generate and share processing templates for
image services

Sharing Imagery
What is ArcGIS Image Server?
• Part of ArcGIS Enterprise
• Serves large collection of data for analytical processing
• Allows users to assemble, process, analyze and
manage large collection of imagery
The Enterprise solution to imagery sharing
Source images Mosaic dataset
Image service
ArcGIS Image Server
ArcGIS Image Server
• Dynamic image services
- Web accessible imagery which can have processing applied on-the-fly
• Raster Analytics
- Quickly process and persist data to create new information products
• Ortho mapping
- Processing of satellite, aerial or drone imagery into digital elevation models and
ortho mosaics
• Imagery hosting
- Enables users within organization to upload imagery into ArcGIS Enterprise and
serve it as dynamic imagery layers
Key Capabilities
ArcGIS Image Server
• An Image Service is the primary information model for imagery on ArcGIS Online
- Single Images
- Large collections via mosaic datasets
• Puts valuable imagery to use quickly
• Serves multiple views using the original imagery
• Access the records that make up the mosaic dataset
• Can be used to perform on-the-fly image processing and explore temporal changes
What is an image service?
Sharing imagery from ArcGIS Pro
• Must invoke the wizard from Catalog pane -
not Contents pane
• Share by Reference or Share by Value
• Define processing to be applied by the
server
• Option to allow downloads
• Can enable WMS (Web Map Service) and
WCS (Web Coverage Service) capabilities
• Can publish to ArcGIS Online, Portal and
standalone ArcGIS Server (new feature of
ArcGIS Pro 2.4)

Best Practices
Best Practices…are data specific!
• Imagery Workflows website has best practices and recommended workflows

Best Practices for Managing ImageryStoring source images and data
• Store each collection of image files in a separate directory
• Try to keep the number of files per directory under 1,000
• One mosaic dataset per geodatabase, or at least a small number of them
• Store metadata files in the same directory as your data
• Use a consistent naming convention
Best Practices for Managing ImageryPre-processing and preparation
• Build pyramids for source images
• Identify NoData values
• Familiarize yourself with your data
• Verify the units of measurement
Best Practices for Managing ImageryCreating and Improving Mosaic Datasets
• Default values are your friends!
• Set the appropriate raster type
• Pay attention to metadata
• Use a mask or build footprints to clip the data
- Use Radiometry option OR Geometry option + clip to mask
Best Practices for Managing ImageryCreating and Publishing Image Services
• Publish using share by reference method (instead of copying data to server)
• Caching is recommended for services which will serve as basemap imagery
• Suggest to cache services that were published with low performing or highly
compressed formats
Summary
• Mosaic Dataset
- Primary information model to manage imagery
- Supports dynamic mosaicking and on-the-fly processing
- Can be configured to fit your data
- Can be accessed across the ArcGIS platform when shared as a web service
• ArcGIS Image Server
• dynamic image services

Which Font Should You Use For Your Presentation?
Arial
Please use Arial at all times for your PowerPoint presentation.
Using Arial gives your PowerPoint presentation the flexibility to be used by many people on various
machines without the risk of font compatibility and changing the look of your layout.
Use of Arial Ensures…
Multiple users are able to view the font / Presentation distributed to others picks up the font
Presentation can be used on multiple computers
Did you know?
To quickly update any current presentation
Copy and paste your slides from your current deck into the newest template. The title and ending logo slide will
update automatically.
Videos not working?For video in PowerPoint, animated GIF is recommended. AVI and WMV (native PC files) will work best on a PC platform. H.264
MP4 will work only on PowerPoint 2013 and later.
