'''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<ref> Directions Magazine, June 8, 2011. [http://apb.directionsmag.com/entry/intergraph-and-erdas-from-geomedia-to-imagine-the-big-and-little-pictu/182796 "Intergraph and ERDAS: From GeoMedia to IMAGINE-The Big and Little Picture for this Geospatial Marriage #hex11"]</ref> 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.<ref>GeoInformatics Magazine, July/August 2011 [http://fluidbook.geoinformatics.com/GEO-Informatics_5_2011/#/36/ "ERDAS, Intergraph and Leica"] </ref><ref>GeoInformatics Magazine, January/February 2009 [http://fluidbook.microdesign.nl/geoinformatics/01-2009/ "Extending the Utilization of Geodata throughout Organizations: ERDAS APOLLO 2009"]</ref> 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 largeextensive volumes<ref> Directions Magazine, June 8, 2011. [http://apb.directionsmag.com/entry/intergraph-and-erdas-from-geomedia-to-imagine-the-big-and-little-pictu/182796 "Intergraph and ERDAS: From GeoMedia to IMAGINE-The Big and Little Picture for this Geospatial Marriage #hex11"]</ref> 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 [[Open Geospatial Consortium|OGC]]/[[International Organization for Standardization|ISO]]-based application, ERDAS APOLLO implements a variety of compliant web services<ref> Vector1Media: Spatial Sustain Blog, March 24, 2011 [http://www.vector1media.com/spatialsustain/erdas-11-world-tour-stop-at-digitalglobe.html?utm_source=feedburner&utm_medium=feed&utm_campaign=Feed%3A+SpatialSustain+%28Spatial+Sustain%29 "ERDAS 11 World Tour Stop at DigitalGlobe"] </ref> 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),<ref>Dietz, C. [http://www.istl.org/10-spring/internet2.html Science and Technology Resources on the Internet: Implementing Geospatial Web Services: A Resource Webliography"] Issues in Science and Technology Librarianship, Spring 2010]</ref> 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 ([[ECW (file format)|ECWP]]), which enables serving over 5,000 clients withfrom just onea standard server. Data may also be delivered as tiles using standard or proprietary services such as Optimized Tile Delivery Format (OTDF) ,<ref>GeoInformatics Magazine, April/May 2010 [http://fluidbook.webtraders.nl/geoinformatics/03-2010/#48 "Optimized Tile Delivery Format"]</ref>, 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).<ref>GeoInformatics Magazine, September 2011 [http://fluidbook.geoinformatics.com/GEO-Informatics_6_2011/#/8/ "From the Sensor to the Internet"]</ref><ref>Directions Magazine, December 23, 2009 [http://www.directionsmag.com/articles/erdas-rocks-users-jazzed/122433 "ERDAS Rocks, Users Jazzed"]</ref> Example on-demand processes include line of sight, elevation change, image change detection and NDVI.
