ArcNews Article
Imagery is Core to ArcGIS covers how imagery is integrated into all aspects of ArcGIS.

Key Features

Esri's imagery tools and products enable users to quickly access and analyze imagery, manage catalogs of imagery from various sources, and integrate imagery into more efficient workflows. This maximizes the value of the imagery by making it accessible to many different users and applications.

The ArcGIS platform provides core imagery capabilities, while Esri business partners provide solutions that build on these core capabilities. In combination, this offers organizations using ArcGIS a complete enterprise geospatial solution.

Among the core capabilities of ArcGIS image management are these:

Geospatial imagery is the fundamental base to GIS and mapping devices.

¹ArcGIS for Server Image Services are core services available with ArcGIS for Server. Image services are Web services that are optimized for imagery, returning not only pictures but data values. They include capabilities for clients to control aspects of imagery delivery such as compression for use over low-bandwidth networks and conformance to IT and Web-based standards. Image services make it easy for customers to access imagery quickly from wherever it is located. ²The ArcGIS for Server Image extension broadens ArcGIS for Server capabilities and image services by extending the support to large numbers of images and enabling dynamic mosaicking and on-the-fly processing of imagery. The Image extension eliminates the need to duplicate the source data, which reduces data redundancy and storage requirements. Fast, server-based processing enables on-the-fly creation of multiple image products from a single source.
Integrates imagery with other GIS data Imagery can be integrated into existing infrastructures using the Web standards support of ArcGIS to deliver the imagery.
Fast access to geospatial imagery Imagery can be quickly served and become accessible to large numbers of users almost instantaneously without lengthy load times.
Band combination manipulation, band stretching, and contrast adjustment ArcGIS technology provides numerous built-in tools for enhancing imagery. For example, you can extract bands or stack bands to highlight various ground features.
Server-side reprojection Access imagery in any required projection. The server will correctly reproject the data.
Simplified image management Manage your imagery as individual files, rasters in a geodatabase, or image services.
Centralized management of large volumes of data With only one set of source imagery to maintain, data redundancy and storage requirements are substantially reduced.
Support for standards such as WMS, WCS, KML, SOAP, and REST The ArcGIS platform conforms to open standards and enterprise IT frameworks and supports multiple approaches to standards and interoperability.
Can create image services from any raster dataset Create image services from any raster dataset that ArcGIS can access. These datasets can include multispectral or elevation data.
GIS, CAD, imaging, and Web access Enable access to imagery from a wide range of desktop and Web applications.
Fully scalable The ArcGIS platform scales to meet your current and future technical and functional requirements.
Access to online basemaps ArcGIS Online provides both free and for-fee basemaps in addition to other content, tasks, user services, and developer services.
Usable over low-bandwidth networks Users can control the compression of transmitted imagery, enabling efficient use of imagery over low-bandwidth networks. High compression can be used to provide fast access, while low compression provides optimum image quality.
Serve mosaic datasets Mosaic datasets are a new data model within the geodatabase that manages collections of images and rasters in a catalog, which can associate imagery with metadata, dynamic mosaicking, and on-the-fly image processing. It can be served as a raster dataset (with all required processing done on the fly) or a catalog of footprints and metadata.
Multiple images in a single service A single image service can contain a large number of individual images without the need to premosaic them. These images can be in different coordinate systems and image formats or from different imaging sensors.
Dynamic mosaicking of overlapping imagery Control the order of overlapping imagery in a service, so that imagery most important to you, such as latest date or best quality, is topmost.
On-the-fly processing Perform server-based processing of required imagery as it is accessed, saving time and storage space. On-the-fly image processing means only source imagery needs to be stored, eliminating the need to maintain multiple datasets. As new imagery is added or updates are made to the processing requirements, changes are immediately reflected in accessed imagery, thereby reducing maintenance costs and the latency between data capture and use.
Server-side orthorectification Transform imagery directly from digital cameras and satellites to accurate georeferenced imagery. This can considerably reduce the time between acquisition and use of imagery.
Server-side pan sharpening Sharpen low-resolution multiband imagery with high-resolution panchromatic imagery.
Server-side image enhancements Enhance the imagery to provide optimum visual information. This is especially useful when working with imagery that has high dynamic range from modern sensors.
Creation of multiple products from the same source Generate multiple image products from a single source, each with different radiometric processing, geometric processing, and compression options. This maximizes the information content that can be obtained from the imagery without the need for costly preprocessing or data redundancy.
Access to original image metadata Metadata about the individual images making up any view can be obtained, providing critical information about the source imagery required to make decisions.
