By chance I have been working in GI through most of the significant developments of web mappingI remember asking this question of the European VP of a GI business in 1998? He didn’t really have a good answer! Perhaps you will at the end of this lecture

Let’s start by looking back to the very beginnings of mapping

16500 BCE Star Map in caves at Lascaux, France6200 BCE CatalHyük map, AnatoliaWall painting/carving depicting the positions of the streets and houses of the town together with surrounding features such as the volcano close to the townSome debate as to whether this is a mapClick to buildThink about the plan rather than elevation view

2400 BCE Earliest known Babylonian mapA 7.6 × 6.8 cm clay tablet found in 1930 at Ga-Sur, near contemporary Kirkuk, shows a map of a river valley between two hills. Cuneiform inscriptions label the features on the map, including a plot of land described as 354 iku (12 hectares) that was owned by a person called Azala. Click to buildHills are shown by overlapping semicircles, rivers by lines, and cities by circles. The map also is marked to show the cardinal directions

600 BCE Pythagoras - 350 BCE AristotlePythagoras proposed, and Aristotle put forward six arguments to prove, that the Earth is spherical250 BCE EratosthenesMeasured the circumference of the Earth; introduced a grid to locate positions of places

140 BCE Ptolemy publishes Geographia - a Guide to GeographyDocumented basic principles of cartographyConsiders the problem of map projection, including two different projectionsMapped the known world giving coordinates of the major places in terms that are essentially latitude and longitude.

730 – 1460 Mappae MundiThese maps show coastal details, mountains, rivers, cities, towns and provinces. Some include figures and stories from history, the Bible and classical mythology. Also shown on some maps are exotic plants, beasts and races known to Medieval scholars only through Roman and Greek texts.Prior to its destruction in World War II, the Ebstorf map at 3.5 metres (11 ft) across was the largest surviving mappa mundi. Today that honor is held by the Hereford map which is 1.5 metres (4.9 ft) across.

1360 Gough Map – the 1st British Road MapThe Gough Map is the oldest extant map of the roads of medieval Britain.It is about 115 x 56cm large and was made around 1360. It is named after Richard Gough, who donated the map to the Bodleian Library in 1809.Click to buildEast is on the top!

1440 Gutenberg invents printing pressThe very first technological evolution of mapping was the ability to “mass” produce maps for publication and distributionOne of the factors associated with the end of the middle agesCan the internet be compared with the introduction of printing in terms of info distribution?

1569 Mercator publishes 1st world mapThe golden age of Dutch cartography. One of the first “mass produced” maps!Flemish geographer and cartographer Gerardus Mercator’s world map of 1569 introduced a cylindrical map projection that became the standard map projection known as the Mercator projection. It was a large planisphere measuring 202 by 124 cm, printed in eighteen separate sheets.The name and explanations given by Mercator to his world map (Nova et Aucta Orbis Terrae Descriptio ad Usum Navigatium Emendate: "new and augmented description of Earth corrected for the use of navigation") show that it was expressly conceived for the use of marine navigation.

The history of web mapping is a story of some visionaries even heroes and of several missed opportunitiesLike all histories it is a story of people, events, happenstance and surprises.Any ideas who this guy is?

These 3 guys represent the 3 streams that I want to follow through the last 2 decades as we look at how web mapping developed.Look out for them

1984TeleAtlas formed in Netherlands1985Navtech formed in Silicon Valley1st in car navigation systems ETAK and TeleAtlas

1989 GPS rollout starts Late 1980's - early 90's early hacks of ArcView using CGI scripts“Over 5 years waiting for the vendors to deliver "proper" solutions”

19911st web site onlineSir TBL’s computer acting as the first internet server!

1993 1st Web Map Server Palo Alto Research CentreGenerally considered to be the first web map server, static maps served upXerox PARC Map Viewer was one of the earliest static web mapping sites, developed by Steve Putz in June 1993 at Xerox Corporation's Palo Alto Research Center (PARC). The Xerox PARC Map Viewer was an experiment in providing interactive information retrieval, rather than access to just static files, on the World Wide Web (Putz 1994).Map Viewer used a customized CGI server module written in Perl. Map images were generated in GIF format from two server side programs. MAP-WRITER created the raster images from the geographic database and RASTOGIF would convert the raster image into the GIF format.Xerox has long since discontinued the Map Viewer serviceLongitude, latitude & scale/zoom factor in URL query termsThe Map Viewer was presented in May 1994 at the First International World-Wide Web ConferenceLimited functionality & slow cycle of click & response“The interaction between the user and the map was implemented by a computer code (a Common Gateway Interface or CGI script), which ran on the Web server. Each time the user clicked on one of the links on the page, the user’s Web browser sent a request to the server. The request encoded in it the coordinates of the area that the user was interested in and other options such as the layers that were to be displayed. Once the server received the request, it would execute the CGI script, which would produce the HTML page and the associated imagefile that presented the new map, and then transfer these files over the Internet to the user’s computer. Once the files were received, the user’s browser would render them and show them on the computer’s screen.This interaction mode led to a delay of a few seconds between the user’s action (the click on the map) and the rendering of the map on the screen, with a visible refresh of the whole browser window when the new page was downloaded.This interaction model was the core of most of the Web mapping applications for the next decade.” – Haklay et alClick to build

Genasys start development of web brokerDevelopment of Genasys Spatial Web Broker capability began in 1994 and was officially announced in 1996. This product was designed to allow any web developer to integrate GIS functions, such as routing, into portal applications, e-government applications, and e-business applications.

“Early offers from MapInfo & Esri were desktop products running on server” – EPIn 2000 Dauman (Malaysia) wrote “A few commercial product can be used to develop interesting interfaces such as ArcView Internet Map Server by ESRl, Grasslinks by University ofCalifornia, MapInfo ProServer by Maplnfo and Spatial WebBroker [3]. But, there's a drawback, which involves a very high cost, and it will slow down any process if the demand repeated. As a solution, the use of Map Applet [6] can overcome these high cost problems for interactive presentation of GIS data on web. However, a new problem occurs on how to perform data compression to make it smaller and speed up the transmission process.”1996 ESRI UK Intra Active Maps“Based on Map Objects IMS and designed to provide local authorities with intranet facility to be used in the front office.Datasets in Shapefile format could be accessed and what we would now call “mashed up” to allow LA staff to see anything spatial from planning application boundaries in a windows-like interface, where themes could be turned on and off through a table of contents.Brainchild of Roy Laming with realisation by Consultancy Services – Matt Toon, now at Google was the development lead. From memory we sold 3 licenses before we withdrew the product. It did however allow us to “cut our teeth” on issues of web mapping which came to fruition in a much more profitable way in NLIS Searchflow which used MO Java to do the first commercial-scale polygon editing on the web of which I am aware. ESRI (UK) wrote the editing tools from scratch – ESRI inc used many of the ideas in ArcIMS.’’ - A Coote1996 ArcView IMS extensionArcView 3.0 running on server with scriptingWith the ArcView Internet Map Server extension, you can use ArcView GIS out-of-the-box to put mapping and GIS applications on the Internet. ArcView Internet Map Server makes publishing maps on the Web almost as easy as printing a map. It includes a built-in setup wizard and ready-to-use Java applet to help you publish your data quickly. Interactive maps can be created from a number of different types of spatial data including shapefiles, coverages, SDE layers, DWG, DXF, DGN, and a variety of graphic images. 1996 - MI ProServerA typical installation of MapInfo ProServer, which includes MapInfo Professional, MapBasic, and a range of data and sample applications, is approximately $25,000. MapMarker 2.1 is available separately.Early pricing $59,500 unlimited usage! Vendors tried to apply desktop pricing to web applications!Click – GPS announcement onlyStart of Open Source mapping, just as big guys are getting into the game the Open source community are nibbling

By effectively employing its over 30 years of traditional and digital mapping experience together with its proprietary integration and editing of geographic databases, MapQuest provides comprehensive online mapping solutions to businesses and provides customized maps, destination information and driving directions to consumers. During February 1999, MapQuest delivered over 76.2 million maps and over 14.2 million driving directions through its own website and through third-party websites.

Usage of web mapping was limited by complexity, cost & poor user interaction“In summary, until about 2005, delivery of geographic information and GIS capabilities over the Internet was possible and increasingly more sophisticated but a combination of factors limited their use. Developing an Internet-based mapping application remained complex, and this limited the number of developers and kept the cost of Web mapping high. Importantly, as most of these Internet mapping applications rely on some background cartography, this required purchasing expensive background maps outside the USA, or, even where public domain geographic information are available (USA), a significant knowledge in manipulating these datasets and preparing them for delivery is required.Finally, from an end user perspective, the delivery of geographic information in a graphical form was limited due to network bandwidth, especially as when these standards were first introduced many users were still using dial-up links to the Internet.” - Haklay et al

Early mentions of GeoWeb(link)Some will refer to earlier technical papers dating back to 94 - Dr. Charles Herring in his US DoD paper, An Architecture of Cyberspace: Spatialization of the Internet, 1994New approaches to Geo Information distribution, usability & application development“... the change is not of increased functionality, rather how emerging technologies have created new approaches to geographic information distribution and, most importantly, in the usability and ease of application development” - Haklay

OpenSpace demonstratedTook a year to release!

Emergence of the term Neogeography‘a socially networked mapping platform which makes it easy to find, create, share, and publish maps and places’ - Di-Ann Eisnor“Neogeography means ‘new geography’ and consists of a set of techniques and tools that fall outside the realm of traditional GIS, Geographic Information Systems. Where historically a professional cartographer might use ArcGIS, talk of Mercator versus Mollweide projections, and resolve land area disputes, a neogeographer uses a mapping API like Google Maps, talks about GPX versus KML, and geotags his photos to make a map of his summer vacation.Essentially, Neogeography is about people using and creating their own maps, on their own terms and by combining elements of an existing toolset.Neogeography is about sharing location information with friends and visitors, helping shape context, and conveying understanding through knowledge of place.Lastly, Neogeography is fun . . .” (Turner 2006, 2–3)Approach or mode of thought not a technology"this disregard to past practices is part of the zeitgeist that is central to Web Mapping 2.0." - Haklay et al

“Today, of course, internet mapping services have evolved so that they are available through APIs that anyone can use to create a web-based application or mash-up showing whatever information they like on a map. And of course maps themselves are being made by members of the public with user-friendly tools. Individuals have gone from being simply the consumers of mapping services to the creators of the services and the maps themselves” Sean Phelan, founder of Multimap1993 Deep level tech skills needed to get the crudest map onto a web pageContinued through to 2005 to be the domain of specialists, who probably revelled in their special skill sets combining geo and dev2005 onwards geo becomes simpler and many more can deploy the capabilitiesToday even I can build a simple mashup and embed it into a web page, largely through a user interface and without needing to write any code.Good thing or bad thing?

Why has there been such an explosion of usage of web mapping?“In the early days content displayed on customers' maps was generally focused on their own businesses: properties for sale on estate agent maps; hotels on hotel providers' sites, etc. That has evolved such that today estate agents show schools, local transport, recreation facilities, aerial images, bird's eye images, etc. Hotels show transport, restaurants, bars, museums, etc. as well as the aerial and bird's eye imagery. Some sites also include user-generated content of various types, links to Wikipedia entries about landmarks. Today there appears to be no limit to the type of information that can and is displayed about a place.Internet mapping is not GIS. The GIS industry has historically focused on low-volume, functionally complex applications for professional users. Internet mapping is about delivering millions of map images, very fast at very low cost. The creative and aesthetic side of cartography has a long and rich history, which has largely been ignored by the digital mapping world. The general public expects maps to be intuitive and aesthetically pleasing, and have largely been disappointed with early digital products and online services. When users find maps they like, they return every day.” Sean Phelan, founder of Multimap
