ERDAS APOLLO is a comprehensive data management, analysis and delivery system that enables an organization to catalog, search, discover, process, and securely disseminate large volumes^[1] of both file-based and web-enabled geospatial and generic data. Developed and sold by Intergraph, this geographic information system (GIS) solution is enterprise-class and implements an out-of-the-box service-oriented architecture (SOA).

The primary focus of ERDAS APOLLO is for cataloging geospatial data, including raster, vector, terrain, LiDAR, and 3rd party geospatial web services.^[2] The solution, however, is also capable of cataloging third party web services and virtually any digital object in an enterprise alongside of the geo-data; and into one fully-indexed, human-readable library.

Data model

ERDAS APOLLO provides the ability to develop a complex data model of geospatial data holdings and leverages both proprietary and OGC web service capabilities to deliver hierarchical layers of geospatial data. Organization administrators may expose large volumes of heterogeneous data through homogenous service layers, regardless of the internal physical storage location of the data or the number and quantity of technical factors (i.e. format, sensor model or CRS, bit depth, etc). End users perform complex searches of data assets in the catalog using both metadata and spatial constraints.

Data delivery

An interoperable OGC/ISO-based application, ERDAS APOLLO implements a variety of compliant web services including, but not limited to, comprehensive Web Map Service (WMS), Web Coverage Service (WCS), Catalog Service for the Web (CS-W), Web Feature Service (WFS), transactional Web Feature Service (WFS-T), Web Map Context (WMC), Web Map Tile Service (WMTS), Web Processing Service (WPS) and ISO 19115/19139 metadata standards. ERDAS APOLLO also employs the proprietary high performance streaming imagery protocol Enhanced Compression Wavelet Protocol (ECWP), which enables serving over 5,000 clients with just one standard server. Data may also be delivered as tiles using standard or proprietary services, and full download or provisioning of data via clip-zip and ship is supported.

Server-side Geoprocessing

Providing interoperable geoprocessing services, spatial models created in ERDAS IMAGINE® are published to ERDAS APOLLO and then delivered over the internet. End users can then conduct raster-based geospatial analysis by running an entire model (such as change detection), completely contained within a single Web Processing Service (WPS).^[3] Example on-demand processes include line of sight, elevation change, image change detection and NDVI.

Security

A fine-grain security model supports user and role-based security and also geographical-based tools to specify security including spatial area and scale. Administrators assign access and permissions to users and roles for all data and geoprocesses in the system.

IT standards

ERDAS APOLLO is built on IT standards such as JavaEE and REST, and supports Microsoft SQL Server, Oracle, and PostgreSQL relational database management systems (RDBMS) for persisting intelligent metadata and application specific information. ERDAS APOLLO may be deployed on-site, in a cloud computing environment, and supports clustering.^[4]

Industries served

ERDAS APOLLO suits a wide spectrum of organizations in industries such as government, land management, police and emergency services, defense, agriculture, forestry, transportation, utilities, and environmental monitoring.

Products

Available as Essentials, Advantage or Professional products, each higher tier contains all of the features and functionality of the lower tiers. The Essentials tier enables an organization to catalog and deliver geospatial data plus anything electronic or URL-available, with spatial and non-spatial metadata (e.g. video, pdf, doc, jpg, etc). This tier also enables high performance delivery of large volumes of imagery (pixel) data. The Advantage tier provides centralized management and distribution of distributed, constantly changing, high volumes of geospatial data. The Professional tier provides ERDAS IMAGINE spatial model execution through Web Processing Service (WPS).
