GeoNetwork and ESRI GIS Portal Toolkit Comparison

Transcription

1 GeoNetwork and Comparison The following software are being evaluated for the GeoSUR project for the implementation of GIS portal application for the South American region. The information collected for each software will be provided to the GeoSUR advisory board to be used for evaluation and selection of the portal software. General Requirements Recent Version Type Commercial. Current version of GIS Portal Toolkit is free as long as the ESRI training class is taken and the other prerequisite software is already purchased. Final licensing for GPT 9.3 is under discussion. GPT 9.3 will require ArcGIS Server 9.3 Standard Enterprise. Free and Open Source Operating System Red Hat Enterprise Linux AS/ES 4.0 Update 2 SUSE Linux Enterprise Server 10 Sun Solaris 9, 10 (SPARC) Windows 2000 SP4 Server Windows 2003 SP2 Server Windows Vista SP1 Ultimate, Enterprise, Business Windows XP SP2 Professional Edition MS Windows Linux Mac OS X Potentially any Java Servlet environment Hardware Requirements Memory Requirement Disk Requirement Java Requirement See recommended hardware requirements on See recommended hardware requirements on Note that this depends on deployment models and expected use. See minimum disk space requirements on Note this will depend on type of DBMS, size of the catalog and size of the data used in the map service, gazetteer and optional data extraction service. Java 1.5 SDK is required. Either version 1.5.0_06 or 1.5.0_14 may be used 1 GHz or higher 512 MB memory or higher 30 MB minimum / 250 suggested Java Runtime Environment (JRE 1.5.0) Web Server IIS5, IIS6 or Apache NA, Apache or IIS can be configured to redirect traffic to the servlet engine Servlet Engine Apache Tomcat or Note: other Servlet engines (IBM WebSphere, Oracle Application Server, Sun GlassFish, ServletExec, ) may be supported on a case-by-case basis per project requirements. Apache Tomcat or Jetty Database Oracle 9i Oracle 10g Microsoft SQL Server 2000 SP4 JDBC Compliant DBMS such as MySQL PostgreSQL

2 Other Required Software Required Apache Software Foundation Packages Microsoft SQL Server 2005 SP2 PostgreSQL 8.3 ArcGIS Server 9.3 Standard Enterprise (includes ArcSDE), ArcGIS Desktop is advised to author/manage oher services used in GPT and manage metadata, GPT 9.3 works with an LDAP user store and authentication service. Verified to work are: Apache Directory Server Sun OpenDS Microsoft ActiveDirectory Other LDAP servers may be supported on a case-by-case basis per project requirements. Sun JSF Framework Sun Java Mail Sun JavaBeans Activation Framework Apache Commons Struts Tiles JSP Standard Tag Library Apache Commons File Upload Apache Commons IO JUnit Z39.50 Toolkit Oracle MS SQL Server NA Java applications included: Lucene Jeeves McKoi Jetty GeoServer Schematron InterMap NA Supported Browsers GPT 9.3 supports IE 6+, FireFox, and Safari. Firefox 1.5+, Internet Explorer Win v6+, Safari 3+ (Mac OS X Leopard) Notes Common practice is to install Catalog Services and Metadata Viewer on dedicated server with Catalog Services database installed on separate dedicated server, however, everything can run on one machine. Alternatively, various services (basemap/searchmap/placefinder) may be used from ArcGIS Online and would thus not be hosted on the server, thus reducing the load on the server. These services are free of charge. Common practice is to install all GeoNetwork components on a single machine. Could be distributed. Can interact with other GeoNetwork instances in a federated catalgoue environment Standards Implementation Main Components Metadata Standards Portal Module, Map Viewer, Administrator Module, Publisher Module, CSW Client for ArcMap and ArcGIS Explorer, Harvesting Module FGDC, ISO 19115, ISO 19139, Dublin Core. Note: GPT 9.3 allows additional metadata profiles to be configured by the implementor of GPT without compiling. Metadata editor, metadata template system, user & group management, harvesting management, backup management, map viewer, pdf map printing, sending WMC & map preview by , map server (GeoServer) ISO19139 (19115 & 19119), FGDC, Dublin Core

3 Portal Acting as a Client Metadata/Catalog: ArcIMS Metadata Server client, ISO with GEO Profile (ANSI Z39.50 with FGDC), Open Archives Initiative (OAI-PMH), OGC (ebrim, OGCCORE, and APISO profiles as implemented by several vendors), Web Accessible Folder (WAF). Other Services: WMS, WFS/GML format conversion Metadata/Catalog: Other GeoNetwork nodes, WebDav, CSW ISO Metadata Application Profile, Open Archives Initiative (OAI-PMH), ISO with GEO Profile (ANSI Z39.50 with FGDC) Z39.50 client is included but currently disabled and being revised. WAF is supported via WebDAV Portal Acting as a Service OGC WMS that composites remote WMS requests, OGC CSW server, ArcIMS Metadata Service, ISO GEO Profile service, OGC CSW ebrim Application Profile, OGC CSW baseline, RSS/Atom OGC WMS, OGC CSW ISO Metadata Application Profile, ISO GEO Profile, OpenSearch protocol w/georss, RSS/Atom ** Will WFS, WCS or WMC be supported in the future? Yes, WMC is already. WFS and WCS will be supported through OpenLayers in the future OGC Portal Reference OGC Standards Compliance Information on OGC portal information may be found at #ESRI Since GIS Portal Toolkit 2.0 we have supported various OGC specs both as a client (WMS, WCS, WFS, WMC) and as a server (CSW). GPT 9.3 is tested with WMS 1.0, 1.1, 1.1.1, 1.3 WFS 1.0, 1.1 WCS 1.0.0, 1.1.0, WMC 1.1 KML 2.2 GeoRSS ESRI submits its software to OGC for interoperability certification. Certificates may be provided upon request. Additionally, GPT supports ArcIMS and ArcGIS Server map services Mostly - It now supports all components of the portal reference due to the embedded GeoServer map server OGC WMS CSW 2.02 Reference implementation for CSW and 2.0.2, GeoServer is reference implementation for WMS and WFS. It also supports WCS and KML output Software Features Metadata Creation and Publication 1) Create metadata using ArcCatalog or any XML editor and upload to portal 2) Post metadata using portal online metadata entry form 3) Make metadata available on web server and register for harvesting GPT 9.3 includes a highly customizable metadata editor that can Online editing of metadata with powerful template system. Scheduled harvesting and synchronization of metadata between catalogs 1) Create metadata using online editor 2) Upload XML 3) import or export MEF files that contain metadata, previews, data,

4 be configured by the implementing organization (without coding) to support arbitrary metadata standards and validation rules. privilege settings and categories Metadata Validation GPT 9.3 will have a publishing tool for ArcCatalog that will go through a user s folders and fetch metadata for resources that is then published to a GIS Portal. This includes files, personal geodatabases, as well as enterprise geodatabases. Can validate against Dublin Core, FGDC, ISO 19115/ISO19139, ISO19119/ISO Publishers are informed of records that fail the validation. See above for additional profile support that may be configured by implementing organizations. It validates structure against all metadata schemas (19139, FGDC and DC) and also allows for schematron validation rules to validate on content (this is a second step validation that goes well beyond just format validation) Metadata Search & Discovery Portal Topics Types of Metadata Searches Access to Spatial Resources Visualize Spatial Resources Portal administrator can review and approve all technically validated metadata before final posting. Validation rules are configurable as part of the metadata schema definition. Searching metadata, sort results, relevance (both textual and spatial) Channel editor to provide access to key content, applications and events At GPT 9.3 the channel editor is replaced with integration with content management systems or Wiki software using Single Sign-on authentication when supported by the CMS software and leveraging the GPT REST interface 1) Free text search 2) Geographic search 3) Thematic search, 4) Temporal search, 5) Resource type search Search is possible using a web interface, a OGC CSW interface, or a REST interface that supports the OpenSearch protocol ( Link Directly to URL, View information as live map, download data from implementor s database. Portal map viewer uses distributed sources (combine WMS, WFS, WCS, ArcIMS, ArcGIS Server, GeoRSS), Save map views, change projection on fly, extensive query functionality, and map markup. Metadata can be approved via access constraints (ie, the portal administrator can restrict access to groups of users) There s a user profile Content Reviewer that is allowed to publish content on the internet Free text search. Geographic Search. Can search on local and distributed catalogs. Sort on relevance, rating, popularity and change date. Discover through (geo)rss search. Discover through social network bookmark sites (delicious, digit, facebook, stumbleupon) Allow to make an entry a featured map. Featured maps appear randomly on the front page 1) Free text search 2) Geographic search 3) Category search 4) Advanced search View Metadata, Download Data, Interactive Map, Graphic Overviews, View OGC map services in Google Earth InterMap is java based map viewer which can use distributed sources. Save map views, open map views, send map views by (all with annotations that can be added in the GUI). Direct access to Web Map Servers that can be preconfigured Cannot currently change projection on the fly but will be able to once OpenLayers is integrated.

5 Print Maps Save Maps User Roles Printing maps are supported (using map templates), as well as exporting maps to SVG or as an image. Save as a Web Map Context (WMC) file or save map to portal for reuse Administrators, Publishers, Channel Stewards, Registered users. Configurable in LDAP, so they can match existing organizational roles Online map layout generation - PDF export Save as PDF Files, Save as Web Map Context (WMC) files Group and user management. Uses Privileges, roles and user groups. Administrator, User Administrator, Content Reviewer, Editor or Registered User Data Security Customizable Interface Publishers can designate if metadata is available to all users or to only specific groups of users. GPT 9.3 integrates with ArcGIS Server security capabilities and LDAP. Achieved through a series of installation specific file content value inputs and through resource file content that informs the basic toolkit functionality with graphics and text GPT 9.3 supports skins/themes that implement a user interface look-and-feel. Users may modify navigation elements, layout. Add custom topics etc. Fine grained access control Interface based on main components and a CSS files for toolbar graphics and HTML formatting. Achieved through XML transformation templates Internationalization Interface can be translation to any language Interface can be translated to any language Available Language Packs Chinese, Dutch, French, German, Spanish Translations available for English, French, Spanish, Italian, Dutch, German, Chinese, Arabic. Greek is coming and others may be out there in the community, but not in core yet. This includes translations done in Brazil for instance General Features Ease of use (final user as well as administrator) Skills needed to administer/upgrade the site (programmer, user with general ICT skills) Speed Simple vs advanced search. Hide functions not applicable to user, My searches/maps, consistent navigation, context sensitive help ESRI and its authorized trainers provide full supported training on configuration and managing GIS Portals as a user interface to SDI. There is a bigger picture beyond a GIS Portal that we address in these classes. Apart from a website, you need to consider why a GIS Portal is created and then support that. GPT is used in GOS to deliver less than 3 second response times on a 200,000 item catalog. ESRI has a long history of providing system design advice to organizations across the world. This experience may be used to help clients determine Ajax based end used GUI should make interface more interactive. No popup windows General user skills via GUI for most functions. Search is based on Lucene indexes, making searches fast performing

6 Possibility of incorporating or interacting with gazetteer services Operational implementations (how many around the world?) Community of programmers (# active programmers) How likely it is to be updated in the near future) Institutions using it in Latin America Institutions using it other regions the appropriate hardware architecture for a GIS Portal. This is not limited to search performance, but also covers availability, failover scenarios, certification and accreditation advise, integration into existing enterprise architectures, etc. Fully supported using ArcGIS Server locator service. This may be customized to support street address geocoding, single field geocoding, combinations, custom, etc. Gazetteer content may be exposed as OGC WFS Gazetteer Service (discussion paper) is in use in over 50 production, nonprototype sites across the world. ESRI and its distributor and business partner network. Additionally several client organizations have the source code to the portal application licensed and are developing custom functionality. ESRI is committed to provide full support using its technical support channel and the online support website Sistema Nacional de Información Territorial (Chile) Instituto Geográfico Agustín Codazzi (Colombia) - SERVIR: Organizations implementing include, but are not limited to: National Spatial Data Infrastructure portals USA Geospatial One-Stop, Norway, Egypt, Columbia Western Australia Land Information System Clearinghouses (various states in USA and government agencies in Europe), Regional and special interest Portals: GEOSS UNEP GRID/DEWA Conservation Geoportal SERVIR Mesoamerican Visualization and Monitoring System Enterprise SDI portals US EPA US NOAA NATO Easy if available (instead of the fixed country selection box for instance) Many.
