 | Technology: A new Open Source SDI Server Linux OS released |
 A new Open Source (Linux) operating system solution for building Spatial Data Infrastructure (SDI) servers is available after extensive testing by the FP7 Geoland-2 project. The code-name of this product is "AGI SDI Server 2009" after the company, which developed and released this product - the Institute of Aerial Geodesy in Kaunas (Lithuania). This re-mastering of Debian (Lenny) operating system includes the best open source SDI and web mapping software tools in the marked, all pre-installed and pre-configured along with spatial database containers and much more...
The latest version of AGI SDI Server 2009 ISO files for 32 and 64-bit versions of the operating system, as well as installation Manual and a short presentation are available for download at http://www.agi.lt/sdi-iso . Please read the manual carefully before you install the server, and go ahead with broadcasting you GIS data on-line!
Concept
AGI SDI Server is a custom
remastering of Debian Lenny (version 5.0.2), bundled with the best
system management tools, spatial (geo-) data processing libraries,
deployment containers, on-line data distribution services and web
mapping interfaces. It is a complete Open Source Spatial Data
Infrastructure (SDI) server solution, developed by a team of experts
working at the Applied Research Center of the Institute of Aerial Geodesy in Kaunas (Lithuania) under the EC FP7-SPACE-2007-1 project "Geoland2 - Towards an Operational GMES Land Monitoring Core Service"
(Grant Agreement No.218795). The abbreviation "AGI" stands for the
Lithuanian name of the company UAB "Aerogeodezijos institutas"
(Institute of Aerial Geodesy, also known as AGI).
A distinctive feature of AGI SDI
Server is that it is a highly customized system with a completely
pre-installed setup of software and configuration of all elements,
including even database containers, which makes it a fully functional
ready-to-go out-of-the-box solution for powering large-scale Spatial
Data Infrastructure (SDI), implemented on the basis of Open Source
operating system and software technology. AGI SDI Server 2009 also
includes customised scripts designed to automate the process of
configuration and activation of SDI services with minimum input
required from the Administrator.
The
current release of the Server is built on Linux kernel version
2.6.26-17. To avoid any possible hardware conflicts, we reduced the
system down to the absolute minimum of interface requirements. There is
no GUI interface in the current release of the AGI SDI Server 2009,
instead of that we deployed the best available open source web
applications dedicated for management of Linux operating systems and
services. The AGI SDI Server 2009 uses all the latest
versions of applications and libraries available from Debian 5.0.x
repositories, and there are no system components and applications,
which would be "locked" to a certain version with pending restrictions on upgrades.
SDI Software
AGI
SDI Server has a complete set of tools and applications for effective
and user-friendly management of the Linux system, it's users and
databases, as well as support of the core Internet services, including
file transfer protocols, web interfaces for building SDI, web mapping
projects and publishing of the on-line content.
There are 4 AGI SDI Server 2009 activation options:
1. LITE version (GeoServer WMS, WFS and WCS - no CSW!)
2. PRO version (Deegree CSW, WMS, WFS, WCS, WPS and iGeoPortal)
3. COMBO version (GeoServer WMS, WFS and WCS + Deegree CSW)
4. CAT version (Deegree CSW only)
In Deegree 2.2, there are OGC WebServices for Web Map Service
(WMS) 1.1.1, Web Feature Service (WFS) 1.1.0, Web Coverage Service
(WCS) 1.0.0 and Catalogue Service Web-Profile (CSW) 2.0.0 available.
WMS and WCS are the official reference implementations of the Open
Geospatial Consortium; WFS and CSW are fully transactional. CSW
supports ISO19115/ISO19119 Application Profile and DE-Profile 1.0.1.
More details are available on Deegree 2.2 features web page.
GeoServer 2.0 is fully compliant to WMS 1.1.1, WFS (1.0 and 1.1,
transactions and locking) and WCS (1.0 and 1.1) specifications, as
tested by the CITE conformance tests. GeoServer additionally serves as
Reference Implementation for WCS 1.1 and WFS 1.0 and 1.1. A detailed
description of capabilities is presented in GeoServer features web page.
More information on AGI SDI Server 2009 can be found in the Manual.
