Constantly searching for the best available tools to implement high quality solutions while respecting the unique characteristics of each customer, we have tried, tested and explored, inter alia, the following technologies:

GeoServerGeoServer is an open source software server written in Java that allows users to share and edit geospatial data. Designed for interoperability, it publishes data from any major spatial data source using open standards.
GeoNetworkGeoNetwork opensource is a standards based, Free and Open Source catalog application to manage spatially referenced resources through the web. It provides powerful metadata editing and search functions as well as an embedded interactive web map viewer.
MapServerMapServer is an Open Source platform for publishing spatial data and interactive mapping applications to the web. Originally developed in the mid-1990’s at the University of Minnesota, MapServer is released under an MIT-style license, and runs on all major platforms (Windows, Linux, Mac OS X).
MapGuide Open SourceMapGuide Open Source is a web-based platform that enables users to quickly develop and deploy web mapping applications and geospatial web services. MapGuide features an interactive viewer that includes support for feature selection, property inspection, map tips, and operations such as buffer, select within, and measure.
PostgreSQLPostgreSQL is a powerful, open source object-relational database system. It has more than 15 years of active development and a proven architecture that has earned it a strong reputation for reliability, data integrity, and correctness. It runs on all major operating systems, including Linux, UNIX (AIX, BSD, HP-UX, SGI IRIX, Mac OS X, Solaris, Tru64), and Windows.
PostGISPostGIS adds support for geographic objects to the PostgreSQL object-relational database. In effect, PostGIS spatially enables the PostgreSQL server, allowing it to be used as a backend spatial database for geographic information systems (GIS), much like ESRI's SDE or Oracle's Spatial extension. PostGIS follows the OpenGIS Simple Features Specification for SQL and has been certified as compliant with the Types and Functions.
MapBenderMapbender is the software and portal site for geodata management of OGC OWS architectures. The software provides web technology for managing spatial data services implemented in PHP, JavaScript and XML and licensed under the GNU GPL.
IISInternet Information Services (IIS) - formerly called Internet Information Server - is a set of Internet-based services for servers created by Microsoft for use with Microsoft Windows. It is the world's second most popular web server in terms of overall websites behind the industry leader Apache HTTP Server. As of April 2009[update] it served 29.27% of all websites according to Netcraft.[1] The services provided currently include FTP, FTPS, SMTP, NNTP, and HTTP/HTTPS.
Apache HTTP ServerThe Apache HTTP Server Project is an effort to develop and maintain an open-source HTTP server for modern operating systems including UNIX and Windows NT. The goal of this project is to provide a secure, efficient and extensible server that provides HTTP services in sync with the current HTTP standards. Apache has been the most popular web server on the Internet since April 1996.
DrupalDrupal is an open-source platform and content management system for building dynamic web sites. It offers a broad range of features and services including user administration, publishing workflow, discussion capabilities, news aggregation, metadata functionalities using controlled vocabularies and XML publishing for content sharing purposes.
TomcatApache Tomcat is an open source software implementation of the Java Servlet and JavaServer Pages technologies. The Java Servlet and JavaServer Pages specifications are developed under the Java Community Process.
ServletExecServletExec/AS is a standalone web application server that hosts Java Servlets and JSPs. There are two versions of ServletExec/AS: one for Windows 2008/Vista/2003/XP/2000 and another for UNIX platforms, including Linux, SPARC Solaris, HP-UX and AIX.
ASPActive Server Pages (ASP), also known as Classic ASP or ASP Classic, was Microsoft's first server-side script engine for dynamically-generated web pages. Initially released as an add-on to Internet Information Services (IIS) via the Windows NT 4.0 Option Pack, it was subsequently included as a free component of Windows Server (since the initial release of Windows 2000 Server).
PHPPHP, or PHP: Hypertext Preprocessor, is a widely used, general-purpose scripting language that was originally designed for web development, to produce dynamic web pages. It can be embedded into HTML and generally runs on a web server, which needs to be configured to process PHP code and create web page content from it. It can be deployed on most web servers and on almost every operating system and platform free of charge.
JSPJavaServer Pages (JSP) is a server side Java technology that allows software developers to create dynamically generated web pages, with HTML, XML, or other document types, in response to a Web client request to a Java Web Application container (server).
MySQLMySQL is a relational database management system which has more than 6 million installations. MySQL stands for My Structured Query Language. The program runs as a server providing multi-user access to a number of databases.
MSSQL ServerMicrosoft SQL Server is a relational model database server produced by Microsoft. Its primary query languages are T-SQL and ANSI SQL.
FlexAdobe Flex is a software development kit released by Adobe Systems for the development and deployment of cross-platform rich Internet applications based on the Adobe Flash platform. Flex applications can be written using Adobe Flex Builder or by using the freely available Flex compiler from Adobe.
FlashAdobe Flash (previously known as Macromedia Flash) is a multimedia platform originally acquired by Macromedia and currently developed and distributed by Adobe Systems. Since its introduction in 1996, Flash has become a popular method for adding animation and interactivity to web pages. Flash is commonly used to create animation, advertisements, and various web page Flash components, to integrate video into web pages, and more recently, to develop rich Internet applications.
MapFishMapFish is an easy-to-use and extensible web 2.0 mapping application framework. MapFish is composed of two parts: MapFish Client and MapFish Server. MapFish Client is a JavaScript framework based on OpenLayers for the mapping part, on ExtJS and GeoExt for the GUI part. MapFish Server is responsible for server side treatments and is composed of several modules which can be implemented in several languages such as Python, Java, Ruby, PHP or others.
OpenLayersOpenLayers is an open source (provided under a modified BSD license) JavaScript library for displaying map data in web browsers. It provides an API for building rich web-based geographic applications similar to Google Maps and Bing Maps. The library includes components from the Rico JavaScript library and the Prototype JavaScript Framework.
ExtExt is a JavaScript library for building interactive web applications using techniques such as Ajax, DHTML and DOM scripting. Originally built as an add-on library extension of YUI, Ext includes interoperability with jQuery and Prototype. As of version 1.1, Ext retains no dependencies on external libraries, instead making their use optional.
GeoExtGeoExt brings together the geospatial know how of OpenLayers with the user interface savvy of Ext JS to help you build powerful desktop style GIS apps on the web with JavaScript.
ArcIMSArcIMS is a solution for delivering dynamic maps and GIS data and services via the Web. It provides a highly scalable framework for GIS Web publishing.
ArcGIS ServerArcGIS Server connects people with the geographic information they need. Organizations use ArcGIS Server to distribute maps and GIS capabilities via Web mapping applications and services to improve internal workflows, communicate vital issues, and engage stakeholders.
ArcSDEArcSDE (Spatial Database Engine) is server software by ESRI that spatially enables a Relational Database Management System. The spatial data may then be used as part of a geodatabase.
