2 Agenda The Problem The Challenge: concrete use case The Solution gegis 2.0 The start What is gegis 2.0? Open, Open, Open: Standards, Architecture, OSS MAJAS, the editing framework

3 Agenda The Problem The Context: GIS The Challenge: concrete use case The Solution gegis 2.0 The start What is gegis 2.0? Open, Open, Open: Standards, Architecture, OSS MAJAS, the editing framework

4 The Context: GIS GIS = Geographic Information Systems A mapping technology. Allows users to create and interact with a variety of maps and data sources. Integrates databases with geo-referenced spatial data (maps tied to specific known locations). The data presentation can be defined by the user. GIS projects range from global projects to site specific. gegis 2.0 Open-Source Platform for editable GIS web applications

5 The Context: GIS Web publishing spatial enabled enterprise applications Revenue Data Analysis Desktop tools Time

6 The Problem Sharing and integrating geografic data is often hell not to mention updating

7 The Challenge: Concrete Use Case Let s take a concrete example Distribution of geographical data via CD

8 The Challenge: Concrete Use Case Housing development project Local version Databa se Local GIS system Adapt parcel numbers Design documents Send new parcel data CD or file to administration transfer Manual gegis 2.0 Open-Source process Platform for editable GIS web applications p. 8

9 The Challenge: Concrete Use Case Federal Parcel Administra tion Accept new Parcel registration Physical distribution CD or file transfer Manual process More than one year Send data to Responsible update agency cycle? Prepare data for distribution Load data into system First use gegis 2.0 Open-Source Platform for editable GIS web 9p. applications 9 Master Databa se

10 The Solution Life can be simple So the solution should be simple Shouldn t it? gegis 2.0 Open-Source Platform for editable GIS web applications

11 The Solution: Life Can Be Simple Input SOA, OGC Parcel administration/validation Use at own risk Use accepted version gegis 2.0 Open-Source Platform for editable GIS web applications

13 gegis: The Start e-governement project (CORVE-RWO) Thin-client Geographic Data Editing Re-usability Easy-of-use Offer as Open Source Project Specific demands (built-in processes, work flow) Limited budget / short timeframe

14 What is gegis 2.0 gegis 2.0 is an Application Framework Thin client GIS-RIA Browser based topological editing & snapping Configurable electronic service Editable intelligent SDI node Platform independent Ensures privacy of data

15 gegis 2.0: 3 times Open Open, Open, Open Open Standards Open Architecture Open Source Software

16 gegis 2.0: 3 times Open 1. gegis 2.0 supports Open Standards OGC WMS WFS W3C SOA http XML JSON

17 Open Source and open standards gegis uses geoserver to adapt and support open standards. geoserver is supported by a huge community, working together with OGC, so guaranteeing the support of the standard. gegis 2.0 Open-Source Platform for editable GIS web 17 applications

18 gegis 2.0: 3 times Open 2. gegis 2.0 has an Open Architecture Supported patterns Command pattern MVC pattern Observer pattern Architecture Microscopic view Frontend Backend Macroscopic view webservices

19 gegis 2.0: Architecture Persistence tier Application tier Protocols Presentation tier JSON Interface Dynamic SVG document (RIA Ajax/Dojo) Geo Web Services Managers Presentation Logic Geo Web Services Other desktop clients GEO Databas es Config XML SOAP App Generator

20 gegis 2.0: Architecture - Web Services Domain 4 App 4.1 Service 4.2 Service 4.3 Domain 2 Service 2.1 Service 2.2 SOA Domain 1 App1.1 App1.2 Domain 3 App3.1 App3.2 Service 3.3

21 gegis 2.0: 3 times Open 3. gegis 2.0 is an Open Source Software Stack geoserver WMS Server WFS Server Hibernate Spatial geodatabase File system Real time storage (track & trace) MAJAS

22 MAJAS, The Editing Framework MAJAS was designed: to commoditize GIS web technology to offer an end-to-end GIS solution to allow simple integration of GIS in web applications MAJAS is offered as an open source web mapping framework gegis 2.0 Open-Source Platform for editable GIS web applications

23 MAJAS: Architecture The MAJAS Architecture Front-end Thin client GIS engine Desktop GIS in the browser Back-end Extensible Seamless integration with existing J2EE world gegis 2.0 Open-Source Platform for editable GIS web applications
