What is the mosaic dataset?
•
A geodatabase data model used to catalog and process your collections of imagery -
•
Stored as a table and viewed as a table or image
Indirect pixel management -
Images can remain in their native format on disk or be loaded into the geodatabase
•
Unlimited size*
•
Provides dynamic mosaicking and on-the-fly processing
•
License to create/edit – Standard or Advanced
Building a mosaic dataset
Simple workflow 1.
Create mosaic dataset
2.
Add imagery (raster type)
3.
Optionally, edit properties and functions
Creating mosaic datasets in python
•
Mosaic Dataset toolset -
Create Mosaic Dataset tool
-
Add Rasters To Mosaic Dataset tool
•
All tools are accessible through arcpy
•
Useful python API -
Iterator -
-
ListRasters
Cursors from arcpy.da -
arcpy.da.SearchCursor
-
arcpy.da.UpdateCursor
Customizing mosaic datasets
1. Customize
raster type (art.xml)
2. Add
/ join / calculate fields
3. Edit
properties
4. Edit
raster function (rft.xml)
5. Pyramids,
statistics, overviews, color correction,
seamlines 6. Create
referenced mosaic dataset
Raster products – NEW
•
•
•
Simplifies using sensor data -
Quick and easy visualization of common band combinations
-
Simple drag-n-drop, less clicking
Key metadata -
Sensor name
-
Acquisition date
-
Wavelength
Function templates -
•
Multispectral, Pansharpen
Temporary function raster dataset
Data discovery & mosaic dataset customization
What is an image service?
•
It is imagery or raster data made available by a server to a client application
What can you do with an image service?
•
Use it as an image (visual analysis)
•
Use it as raster data (pixel analysis)
•
Access it as a catalog (mosaic dataset)
Image service source data
•
Data sources -
Raster datasets
-
Mosaic datasets -
-
Requires ArcGIS Server Image Extension
Raster or mosaic layers -
To control rendering
-
Preset some layer properties
-
Predefined query
How can you access an image service?
•
ArcGIS Desktop
•
ArcGIS Explorer
•
Web APIs (Silverlight, Flex, JavaScript)
•
ArcGIS.com
•
REST, SOAP
•
WMS, WCS, KML
•
3rd Party Applications
Publishing an image service
•
New publishing workflow
•
Register databases
•
Share from data source
•
Requires service definition (.sd)
Publishing interface
Publishing interface – Capabilities
Publishing interface – Operations
Publishing interface – Parameters
Publishing interface – Parameters
Service REST Admin API – Create Service
•
Service administration -
Create service
-
Edit service configuration
-
Delete service
•
Generate token to use admin API
•
URL sample 1: -
•
http://skye:6080/arcgis/admin/services/createService?se rvice=....&token=....
URL sample 2: -
http://skye:6080/arcgis/admin/services/Portland_wNDVI.I mageServer/edit?service=...&token=...
REST requests through Python
•
Requires service definition (.sd) or JSON file
•
Make REST calls in python packages -
urllib2
-
json
Publish and use image services in Python
Summary
