1 Integrating Imagery into ArcGIS Runtime Application Jie Zhang, Zhiguang Han San Jacinto, 5:30 pm 6:30 pm

2 Overviews Imagery is an essential component of ArcGIS - Visualization, Processing and Analysis - Imagery Data Management - Dissemination with Image Service many more Imagery support in Runtime SDK release - Visualize local Imagery data with ArcGIS Runtime SDK - On-the-fly image processing using raster functions Road Ahead - Cloud Raster Format, Image Service Raster etc.

3 Working with Imagery in ArcGIS Desktop/Server ArcGIS supports imagery data management from various sources - Over 100 native image formats - Over 60 different sensors supported - Satellite - Aerial cameras - UAV/UAS cameras - Scientific data NetCDF/GRIB/HDF Thermal Radar

4 Working with Imagery in ArcGIS Desktop/App ArcGIS provides many tools for imagery processing and analysis Geporocessing tools Dynamic raster functions

5 Image Management using Mosaic Dataset ArcGIS provides image collection management solution through Mosaic Dataset - Create mosaic dataset in supported geodatabase - File geodatabase - Enterprise geodatabase (Oracle/PostgreSQL/SQL Server e.t.c) - SQLite geodatabase (in Runtime) - Referencing original image source - Dynamic mosaicking - Support on-the-fly raster function - Can be shared as image service through Image Server Desktop Server Collections of Imagery & Rasters

6 Sharing images through Image Server Image service provides image collections dissemination solution - Scalable image collection sharing millions of images in single image service - Dynamic mosaicked pixels - Fully customizable server-side on-the-fly processing - Embedded metadata accessible through API: - Categorized classes for thematic data - Multidimension information for scientific data - Mensuration - Identify and Profiling.. many more Query info Analysis and processing Image as a Service Rendering

7 Our mission Bringing this rich set of functionalities for working with imagery from ArcGIS Desktop and Server apps to Runtime SDK developers.

8 Runtime SDK release Raster and Mosaic Dataset Raster Object - Read supported format directly - No write yet Mosaic Dataset Raster Object - Support read and create (create only available in ios and.net SDK) - Subclass of Raster Object - Stored in SQLite database - Desktop mosaic dataset can be converted to mobile mosaic dataset

9 Runtime SDK release Raster Layer/Render/Function Raster layer - Create from raster object Raster renderer - 5 different raster renderer - Some are unique to runtime Blend renderer Raster function - Create from JSON - Compatible with image service renderingrules in REST API - 12 built-in raster functions set to init init Raster Function Raster Layer Raster init Raster Renderer Raster data set to Raster Function Arguments set to

10 Raster Function in Runtime SDK Use runtime native raster functions set to set to - A subset of raster functions in Desktop apps - Not the same as rft.xml Raster functions can be chained to build raster function template Raster Function Raster Function Arguments Raster Function Built in system functions: Hillshade Stretch Clip Geometric Colormap Colormap to RGB Color Ramp Extract Band Pansharpen Raster Calculator Mask Composite band Won t be able to fit in one slide next year

11 Raster Function in Runtime SDK JSON representation of raster function or raster function template Hillshade

12 ios SDK sample demo Jie Zhang

13 ios SDK sample - Code sample for creating raster and rendering raster layer in map

14 Convert Desktop mosaic dataset to Runtime Mosaic Dataset to Mobile Mosaic Dataset Geoprocessing tool from Pro Convert existing Desktop/Pro version mosaic dataset to mobile mosaic dataset (will create SQLite database) - Support selection query and clipping - Persist raster functions unsupported by runtime to images on disk - SQLite mosaic dataset created in Runtime cannot be use in Desktop apps

15 ios SDK sample - Code sample for creating mosaic dataset

16 ios SDK sample - Code sample for applying raster function

17 Road Ahead - What s Coming in Update 1 and beyond Cloud Raster Format (CRF) - Local - In the cloud (Amazon S3, Microsoft Azure e.t.c.) Image Service Raster - A new raster data source - Used in a raster layer or as input to Raster Function Demos

18 Cloud Raster Format (CRF) - Accessing the same data source used in ArcGIS Desktop and cloud based raster analysis - Using LERC based compression for fast data encoding/decoding on the fly. - Support both lossy and lossless compression - Works extremely well on floating point data, such elevation data - Works equally well for RGB color images.

19 Working with Image Service with Runtime SDK - Create Image Service Raster from Image Service URL - Apply client-side raster function on Image Service - Support server-side rendering rules
