  1. Module: Web GIS Principles and Applications By: Erik Zheentaev erik_jeentyaev@yahoo.com Geodesy and Geoinformatics Department, KSUCTA

  2. Web GIS Outline Aims and objectives Introduction Theory Resources/references Case studies Conclusion Practical session, assignment Q/A

  3. Web GIS Aims and Objectives The course introduces basic Web GIS concepts, functions and architecture; design and publication of maps through the internet; applications in environments. After completing the module, students should be able to: - identify the framework of Web mapping - design and publish web maps - demonstrate a clear understanding of the Web mapping standards - explain the types of Web mapping applications

  4. Web GIS Introduction • The Web GIS is one of the Geoinformation Technology fields. • Thebasictasksof Web GIS are: • Visualization - spatialrepresentationoftheexistinginformation • Simplification of work with the spatial information in a web; • Managements and publication of spatial data, search and other services based on a site of objects (LBS - location based services)

  5. Web GIS What Is The Internet? • A vast network connecting computers throughout the world... …so that those computers and their contents are easily accessible to each other

  6. Web GIS About Internet

  7. Web GIS Client/Server Architecture • At least two computers involved • SERVER: computer that houses centralized programs and data • CLIENT: user’s computer connected to a server • Communicate over a network • LAN, WAN, the Internet • Communication built on TCP/IP

  8. Web GIS Experience/Skills Graphic Design Digital Mapping Computer Programming Cartographic Theory Web Design & Internet Mapping GIS Analysis DatabaseDevelopment

  9. Web GIS WebGIS Advantages • Single centralized dataset • Low cost of hardware/software • Ease of use • web browser based, minimal training required • Wide access to GIS data & functionality • linkages with other depts & organizations • potential for release of portions to public

  10. Web GIS What WebGIS Software is Available? • ESRI: ArcIMS • AutoDesk: MapGuide • Intergraph: GeoMedia WebMap • UMN: MapServer • MapInfo: MapXtreme • Caris: Spatial Fusion • Bentley: ModelServer Publisher • …and many others…

  11. Web GIS What is MapServer? MapServer overview MapServer is a popular Open Source project whose purpose is to display dynamic spatial maps over the Internet. Some of its major features include: • ability to run on various operating systems (Windows, Linux, etc.) • support for popular scripting languages and development environments (PHP, Python, Perl, Ruby, Java, .NET) • on-the-fly projections • high quality rendering • fully customizable application output • many ready-to-use Open Source application environments

  12. Web GIS MapServer Input Data Formats • Raster • TIFF/GeoTIFF • jpeg, giff • …and 70+ others via GDAL • GDAL = Geospatial Data Abstraction Library • Vector • ESRI shape files, ESRI ArcSDE • PostGIS, Oracle Spatial, MySQL • and 20+ others via OGR

  13. Web GIS WebGIS Spatial Database • PostgreSQL • Robust RDBMS • Access via SQL or GUI (e.g. PGAccess) • PostGIS • “Spatial-enabler” for PostgreSQL • Supports Geometry Column data type and functions • MapServer can retrieve input data from PostGIS

  16. Web GIS MapServer Architecture

  17. Web GIS Map Server applications are Map File and PHTML pages

  18. Web GIS Resources/references • http://gishosting.net • MapServer, PostGIS, PHP/MapScript, CartoWeb • Plans (us$/mo): Starter (20), Pro. (30), Academic (10) • http://treelineweb.ca • MapServer, PostgreSQL, PHP, PEAR, Perl, Python • Plans (ca$/mo): One (25), Two (40) – Canada only • http://htmlx.com • MapServer, PostgreSQL, PHP • Plan: us$ 20+ / month • http://www.MapSherpa.com(DM Solutions) • MapServer, ASP, PHP, ColdFusion, Perl • Services: Mapping API access, Custom Solutions

  19. Web GIS Case studies • Access to GIS data and functionality • Can add value to web sites • Examples: • Service Location • Service Delivery • Data Access • Data Commerce

  20. Web GIS Web map with MAP SERVER

  21. Web GIS Identification

  22. Web GIS Web Map Queries

  23. Web GIS Web Map Query Results

  24. Conclusion Creating of centralized WebGIS database will lead to success in every field of work related to spatial analysis. After completing of the module WebGIS you can build your own map in Internet with different attribute data. It means that you will be architecture but not client (user) of this product. The Laboratory exercise and assignment you can find in the folder \\gisnet\Pi_webGIS\
