Research on ArcGIS 10 (iii) New Features of Image Technology
Arcgis10 is coming soon in the second quarter and has made great improvements in image/GIS Integration. What new features are there, so let's take a quick look.

ArcGIS 10 is a comprehensive platform for building a complete image solution. It provides a complete image/GIS integrated solution for users to use or manage images.
Arcgis10, including ArcGIS desktop, server, mobile, Geodatabase, geoprocessing, and Web APIs, has been optimized for image management, processing, publishing, and usage.
1) desktop-provides a unified environment for managing and using space data in all formats, including images.
2) server-supports advanced image capabilities, such as dynamic mosaic and dynamic processing.
3) mobile uses images as the basemap for visualization and verification.
4) Geodatabase-a warehouse that stores and organizes spatial data and images.
5) geoprocessing-supports advanced workflow execution that integrates image processing and analysis.

Based on the integrated arcgis10 image/GIS solution, we can conveniently, quickly, in real time and accurately access image data, effectively integrate images in GIS, and provide effective data management and processing, it also provides a large number of image datasets for multiple users, provides scalable solutions from desktop applications to enterprise applications, and provides features ranging from simplicity to complexity, supporting access and availability in multiple formats, enhances Image value, reduces data replication and redundancy, supports a more open interoperability architecture, and supports multiple access methods: kml, WMS, WCS, soap, and rest.
Next, let's "peat" The arcgis10 image technology. What new features are worth looking forward.
1) The new raster data model mosaic Dataset: ArcGIS 10.0 adds the raster mosaic data type-Mosaic dataset in Geodatabase. Mosaic dataset integrates the best features of raster catalog, raster dataset, and image server technologies, and is supported by most ArcGIS applications, including desktop and server. Compared with the previous raster data management method, the new mosaic dataset supports data management, search, discovery, and utilization. The original image is still the original source file or the image stored in Geodatabase. New raster data type. supported:
O Dynamic Mosaic and efficient processing of overlapping Images
O dynamic processing allows you to generate multiple products based on the same data source
O integrated retrieval and discovery functions to optimize specific data
O access and use are integrated into a data type (catalog and mosaic views)
O used as a raster dataset in applications, supporting different analysis operations
O data distribution through Geodatabase and ArcGIS Server (image extension required)
O tools for controlling image sequence, such as time
O The raster type allows you to quickly obtain the latest images using the associated metadata to simplify processing.
O automated processing through geoprocessing
O extension through ArcObjects
O scalability supports large data volumes without compilation and is more dynamic
O seamless mosaic color balancing and Radiation Correction
O previous image server technology migrated to Geodatabase
O available for all license levels (arceditor and above are required for creation)

2) added the image analysis window: ArcGIS 10.0, a new menu window to support quick use of common image processing functions. Although these features already exist in earlier versions, the new image analysis window focuses on simpler workflows and accessibility. Key features are as follows:
O accelerate grid display performance and smooth roaming Scaling
O image enhancement (Dynamic Range Adjustment, brightness, contrast, gamma and re-sampling)
O image interpretation tools, such as Zoom, topup, swipe, flicker and difference between two images
O dynamic processing, such as clip, mask, pan-sharpening, KNN, and shaded relief
O available under all license levels

3) Space Analysis: space analysis performance is improved, and raster datasets can be operated directly, including mosaic dataset. Spatial analysis also provides image classification tools to provide a simple and easy-to-use supervised classification environment. The image classification toolbar provides image classification functions available in space analysis, adds a new feature for collecting and evaluating training samples, and performs interactive supervised classification. In addition, a simple process is provided for interactive acquisition and evaluation of training samples, image classification, and result display.
O easy to create training sample data
O evaluation of training sample data based on statistics and scatter plots
O supervised and unsupervised classification algorithms
O Spatial Analyst available under license

4) enhanced image services: retains the core services of ArcGIS Server to provide efficient image support for large-scale applications. Most raster datasets and layers that contain raster datasets can be directly used as image services.
O access through soap, rest, WMS, WCS, and kml
O multi-client application support, including ArcGIS, ArcGIS Explorer, ArcGIS mobile, ArcPad, and third-party applications, such as AutoCAD and microstation
O The client controls the compression to use images with narrow bandwidth Conditions
O extraction and sending mechanism
O The added processing process can be applied by the server
O ArcGIS Server Standard Edition and advanced edition are available

5) image extended image Extension: The image server technology has been integrated into the Geodatabase mosaic dataset data model. The release of the mosaic dataset function for image service requires the support of ArcGIS Server image extension. When mosaic dataset is published as image service, mosaic dataset can be accessed by applications that can access image service.
O efficient Dynamic Mosaic and dynamic processing on the server side
O access the image mosaic and metadata directory
O User-Defined sorting, query, and selection
O supports image cropping and export
O scalable API access
The use of mosaic dataset on the server requires image extension support, including publishing as image service, loading in map documents, and using it in the geographic processing tool or cache.

6) Video superposition: In ArcGIS 10.0, arcglobe has added support for video playing after spatial registration. For example, video clips obtained from security cameras or drones can be displayed as active videos on the ArcGIS layer.
O was initially designed for developers to provide video integration solutions based on the ArcGIS platform.
O 3D Analyst license available (used only in arcglobe)
