Web mapping or an online mapping is the process of using, creating, and distributing maps on the World Wide Web (the Web), usually through the use of Web geographic information systems (Web GIS). [1] [2] [3] A web map or an online map is both served and consumed, thus, web mapping is more than just web cartography, it is a service where consumers may choose what the map will show. [4]

Introduction

The advent of web mapping can be regarded as a major new trend in cartography. Until recently, cartography was restricted to a few companies, institutes and mapping agencies, requiring relatively expensive and complex hardware and software as well as skilled cartographers and geomatics engineers. [5]

Web mapping has brought many geographical datasets, including free ones generated by OpenStreetMap and proprietary datasets owned by HERE, Huawei, Google, Tencent, TomTom, and others. [6] A range of free software to generate maps has also been conceived and implemented alongside proprietary tools like ArcGIS. As a result, the barrier to entry for serving maps on the web has been lowered. [5]

The terms web GIS and web mapping are often used interchangeably, but the terms are distinct. [1] [2] [3] [7] [8] [9] [10] Web GIS uses and enables web maps, and end users who are web mapping are gaining analytical capabilities from Web GIS, however Web GIS has more applications than web mapping, and web mapping can be accomplished without Web GIS. Web GIS emphasizes geodata processing aspects more involved with design aspects such as data acquisition and server software architecture such as data storage and algorithms, than it does the end-user reports themselves. [11] The term location-based services refers to web mapping consumer goods and services. [12] Web mapping usually involves a web browser or other user agent capable of client-server interactions. [13] Questions of quality, usability, social benefits, and legal constraints are driving its evolution. [14] [15]

Types

A first classification of web maps has been made by Kraak in 2001. [11] He distinguished static and dynamic web maps and further distinguished interactive and view only web maps. Today there is an increased number of dynamic web maps types, and static web map sources. [16]

Analytical web maps

Analytical web maps offer GIS analysis. The geodata can be a static provision, or need updates. The borderline between analytical web maps and web GIS is fuzzy. Parts of the analysis can be carried out by the GIS geodata server. As web clients gain capabilities processing is distributed. [17]

Animated and realtime

Realtime maps show the situation of a phenomenon in close to realtime (only a few seconds or minutes delay). [18] They are usually animated. Data is collected by sensors and the maps are generated or updated at regular intervals or on demand.

Animated maps show changes in the map over time by animating one of the graphical or temporal variables. [19] Technologies enabling client-side display of animated web maps include scalable vector graphics (SVG), Adobe Flash, Java, QuickTime, and others. Web maps with real-time animation include weather maps, traffic congestion maps and vehicle monitoring systems. [16]

CartoDB launched an open source library, Torque, [20] which enables the creation of dynamic animated maps with millions of records. Twitter uses this technology to create maps to reflect how users reacted to news and events worldwide.

Collaborative web maps

Collaborative maps are a developing potential. [21] In proprietary or open source collaborative software, users collaborate to create and improve the web mapping experience. This type of web mapping is the most popular or familiar amongst the population today. [22] Some collaborative web mapping projects are:

Online atlases

Online atlases are collections of maps in a specific period of  time like general reference maps, thematic maps, and geographical information. [23] The traditional atlas goes through a remarkably large transition when hosted on the web. Atlases can cease their printed editions or offer printing on demand. Some atlases also offer raw data downloads of the underlying geospatial data sources.

Static web maps

Static web pages are view only without animation or interactivity. These maps were often used before technological advancements allowed the user to interact. [23] These files are created once, often manually, and infrequently updated. Typical graphics formats for static web maps are PNG, JPEG, GIF, or TIFF (e.g., drg) for raster files, SVG, PDF or SWF for vector files. These include scanned paper maps not designed as screen maps. Paper maps have a much higher resolution and information density than typical computer displays of the same physical size, and might be unreadable when displayed on screens at the wrong resolution. [11]

Web GIS in the cloud

Various companies now offer web mapping as a cloud based software as a service. These service providers allow users to create and share maps by uploading data to their servers (cloud storage). The maps are created either by using an in browser editor or writing scripts that leverage the service providers API's.

Advantages of Mapping Software

Technologies

Web mapping technologies require both server-side and client-side applications. The following is a list of technologies utilized in web mapping.

Impact on society

Web maps have become an essential tool for many, [31] as illustrated by a 2021 labor strike demanding (among other things) a certain type of map. [32] Web mapping has allowed for a more environmentally conscious way of navigating location. With the creation of web mapping, people do not have to use paper maps anymore, as it is accessible through the internet, benefiting our environment. [33] Also, atlases or paper maps that were accessed could have been outdated. With web mapping, in real time, users are able to get step by step directions to a location based on where they currently are located with the most current geographical information. It also allows you to choose routes with distances and estimated times of travel for each. You can even choose your mode of transportation like driving or walking.

Another benefit is that web mapping has allowed more of the general population to access this technology because it is free and accessible to anyone with an internet connection. It also gives us real-time updates about traffic and road conditions which can lead to safer travels. Although not a common use, web mapping can be used to learn more about culture and history. You can explore historical maps, cultural landmarks, natural features, parks, trails, report issues, natural hazards, pollution, and much more. [34] By doing this, we are able to create a safer and more welcoming community to live in.

As much as web mapping has helped simplify our lives, there are also negative social consequences to the use of web mapping. There have been concerns raised about the privacy of personal information while using web mapping. It allows government agencies to create massive databases on individuals and their behaviors while the private sector keeps records of personal information. [33] This issue continues to be challenged and negotiated as web mapping has become more relevant. As the use of web mapping has increased, so has the amount of distractions while driving. [34] Drivers can alter their focus away from the road to their device very easily, which could result in a multitude of  negative social consequences and safety concerns.

While there are many benefits to web mapping allowing anyone to access, create, and distribute maps, many have raised ethical concerns. [35] [36] The web facilitates the spread of misinformation, and people without strong understanding of cartography can publish seemingly authoritative products that may mislead the public. [35] [36] [37] This saw significant attention during the COVID-19 pandemic, where the prevalence of improper maps on dashboards contributed to the infodemic. [36] [37] [38]

Web maps require the internet to host, so they are subject to link rot, making information inaccessible. [37] Unlike physical maps, this can have major impacts on the historical record if the web map is the only source for the data it presents.

Web mapping is also used in geography games, notably of which is GeoGuessr. A popular browser based game, users are shown an image from Google Street View and must guess the location. The game was received with success upon its launch in May 2013, and skyrocketed to viral popularity during the COVID-19 pandemic as many content creators streamed themselves playing it. [39]

How Web Maps Interact With Human Variation

Web mapping allows you to choose a route of travel with provided directions and real time traffic and road condition updates. [40] Of course, this is only possible with an internet connection. Populations that are associated with lower incomes may not have access to a mobile device with internet as they may not be able to afford it, limiting them of this resource.

This technology might also be limiting to certain generations, as well. Younger generations have been cultured in technology for the majority of their lives, so web mapping is an easy resource for them to use. However, older generations tend to be less efficient with technology, as it was not around for the majority of their lifetimes. [41] This can make it difficult for the older generation to understand how to use web mapping when planning their travels. They will often resort to paper maps or a GPS, as that is what is comfortable to them, even though those resources are less efficient and are more outdated than web mapping.

As web mapping has become more advanced, they have added a walking feature. This has created an opportunity for the population who might not have access to and/or afford to have a car. [41] They are still able to take advantage of this technology to get to a destination by foot. Web mapping has also opened up new possibilities to those who might struggle with a vision disorder. More than a quarter of the world’s population (about 2.2 billion people) suffer from vision impairment. [42] Web mapping has accommodated this large population by adding a speaking feature. When you enter a destination, you can turn your volume on and the maps will speak your directions to you. This is not only convenient for visually impaired people, but also helps limit distractions while navigating.

Web Mapping Barriers

There have been concerns raised about the privacy and confidentiality of personal information while using web mapping. Web maps contain personal information such as locations, identities, or attributes of people, places, or things. If not properly secured, your information can be accessed, copied, or manipulated by unauthorized parties. [40] This allows government agencies to create massive databases on individuals and their behaviors while the private sector keeps records of personal information. [33] It can also lead to privacy breaches, data loss, or legal liabilities. [34]

To prevent these issues from happening, mostly in a work setting, you need to encrypt your data, use secure protocols and servers, and apply access control and authentication mechanisms. [40] Another possible barrier created by web mapping that may challenge web map security is data integrity and quality.

Web maps rely entirely on data sources that could potentially be inaccurate, outdated, or corrupted. If the data is not verified and updated regularly, it can affect the reliability of the web maps. [34] Web mapping can also be vulnerable to data tempering, spoofing, or injection attacks, where false or harmful data can be inserted into web maps. There may also be less threatening situations like when web maps may not be updated on a crash or traffic conditions, or may not take you on the most efficient route. To prevent more of these issues from happening, it is important to report unsafe road conditions or any limitations or uncertainties of any web mapping features.

A geographic information system (GIS) consists of integrated computer hardware and software that store, manage, analyze, edit, output, and visualize geographic data. Much of this often happens within a spatial database, however, this is not essential to meet the definition of a GIS. In a broader sense, one may consider such a system also to include human users and support staff, procedures and workflows, the body of knowledge of relevant concepts and methods, and institutional organizations.

<span class="mw-page-title-main">Esri</span> Geospatial software & SaaS company

Environmental Systems Research Institute, Inc., doing business as Esri, is an American multinational geographic information system (GIS) software company headquartered in Redlands, California. It is best known for its ArcGIS products. With a 40% market share, Esri is the world's leading supplier of GIS software, web GIS and geodatabase management applications.

In computing, the Open Geospatial Consortium Web Feature Service (WFS) Interface Standard provides an interface allowing requests for geographical features across the web using platform-independent calls. One can think of geographical features as the "source code" behind a map, whereas the WMS interface or online tiled mapping portals like Google Maps return only an image, which end-users cannot edit or spatially analyze. The XML-based GML furnishes the default payload-encoding for transporting geographic features, but other formats like shapefiles can also serve for transport. In early 2006 the OGC members approved the OpenGIS GML Simple Features Profile. This profile is designed both to increase interoperability between WFS servers and to improve the ease of implementation of the WFS standard.

In computing, GeoServer is an open-source server written in Java that allows users to share, process and edit geospatial data. Designed for interoperability, it publishes data from any major spatial data source using open standards. GeoServer has evolved to become an easy method of connecting existing information to virtual globes such as Google Earth and NASA World Wind as well as to web-based maps such as OpenLayers, Leaflet, Google Maps and Bing Maps. GeoServer functions as the reference implementation of the Open Geospatial Consortium Web Feature Service standard, and also implements the Web Map Service, Web Coverage Service and Web Processing Service specifications.

A GIS software program is a computer program to support the use of a geographic information system, providing the ability to create, store, manage, query, analyze, and visualize geographic data, that is, data representing phenomena for which location is important. The GIS software industry encompasses a broad range of commercial and open-source products that provide some or all of these capabilities within various information technology architectures.

A Web Map Service (WMS) is a standard protocol developed by the Open Geospatial Consortium in 1999 for serving georeferenced map images over the Internet. These images are typically produced by a map server from data provided by a GIS database.

It also serves as an independent legal entity to which community members can contribute code, funding and other resources.

ArcGIS Server is the core server geographic information system (GIS) software made by Esri. ArcGIS Server is used for creating and managing GIS Web services, applications, and data. ArcGIS Server is typically deployed on-premises within the organization’s service-oriented architecture (SOA) or off-premises in a cloud computing environment.

A Spatial Data Infrastructure (SDI), also called geospatial data infrastructure, is a data infrastructure implementing a framework of geographic data, metadata, users and tools that are interactively connected in order to use spatial data in an efficient and flexible way. Another definition is "the technology, policies, standards, human resources, and related activities necessary to acquire, process, distribute, use, maintain, and preserve spatial data".

Collaborative mapping, also known as citizen mapping, is the aggregation of Web mapping and user-generated content, from a group of individuals or entities, and can take several distinct forms. With the growth of technology for storing and sharing maps, collaborative maps have become competitors to commercial services, in the case of OpenStreetMap, or components of them, as in Google Map Maker, Waze and Yandex Map Editor.

Distributed GIS refers to GI Systems that do not have all of the system components in the same physical location. This could be the processing, the database, the rendering or the user interface. It represents a special case of distributed computing, with examples of distributed systems including Internet GIS, Web GIS, and Mobile GIS. Distribution of resources provides corporate and enterprise-based models for GIS. Distributed GIS permits a shared services model, including data fusion based on Open Geospatial Consortium (OGC) web services. Distributed GIS technology enables modern online mapping systems, Location-based services (LBS), web-based GIS and numerous map-enabled applications. Other applications include transportation, logistics, utilities, farm / agricultural information systems, real-time environmental information systems and the analysis of the movement of people. In terms of data, the concept has been extended to include volunteered geographical information. Distributed processing allows improvements to the performance of spatial analysis through the use of techniques such as parallel processing.

Geographic information systems (GIS) play a constantly evolving role in geospatial intelligence (GEOINT) and United States national security. These technologies allow a user to efficiently manage, analyze, and produce geospatial data, to combine GEOINT with other forms of intelligence collection, and to perform highly developed analysis and visual production of geospatial data. Therefore, GIS produces up-to-date and more reliable GEOINT to reduce uncertainty for a decisionmaker. Since GIS programs are Web-enabled, a user can constantly work with a decision maker to solve their GEOINT and national security related problems from anywhere in the world. There are many types of GIS software used in GEOINT and national security, such as Google Earth, ERDAS IMAGINE, GeoNetwork opensource, and Esri ArcGIS.

<span class="mw-page-title-main">WorldMap</span> Web platform

WorldMap is a web platform for creating, displaying, analyzing, and searching spatial data and other data forms across multiple disciplines.

Vector tiles, tiled vectors or vectiles are packets of geographic data, packaged into pre-defined roughly-square shaped "tiles" for transfer over the web. This is an emerging method for delivering styled web maps, combining certain benefits of pre-rendered raster map tiles with vector map data. As with the widely used raster tiled web maps, map data is requested by a client as a set of "tiles" corresponding to square areas of land of a pre-defined size and location. Unlike raster tiled web maps, however, the server returns vector map data, which has been clipped to the boundaries of each tile, instead of a pre-rendered map image.

<span class="mw-page-title-main">Internet GIS</span> Internet technologies regarding spatial data

Internet GIS, or Internet geographic information system (GIS), is a term that refers to a broad set of technologies and applications that employ the Internet to access, analyze, visualize, and distribute spatial data. Internet GIS is an outgrowth of traditional GIS, and represents a shift from conducting GIS on an individual computer to working with remotely distributed data and functions. Two major issues in GIS are accessing and distributing spatial data and GIS outputs. Internet GIS helps to solve that problem by allowing users to access vast databases impossible to store on a single desktop computer, and by allowing rapid dissemination of both maps and raw data to others. These methods include both file sharing and email. This has enabled the general public to participate in map creation and make use of GIS technology.

<span class="mw-page-title-main">Web GIS</span> Technologies employing the World Wide Web to manage spatial data

Web GIS, or Web Geographic Information Systems, are GIS that employ the World Wide Web to facilitate the storage, visualization, analysis, and distribution of spatial information over the Internet. The World Wide Web, or the Web, is an information system that uses the internet to host, share, and distribute documents, images, and other data. Web GIS involves using the World Wide Web to facilitate GIS tasks traditionally done on a desktop computer, as well as enabling the sharing of maps and spatial data. While Web GIS and Internet GIS are sometimes used interchangeably, they are different concepts. Web GIS is a subset of Internet GIS, which is itself a subset of distributed GIS, which itself is a subset of broader Geographic information system. The most common application of Web GIS is Web mapping, so much so that the two terms are often used interchangeably in much the same way as Digital mapping and GIS. However, Web GIS and web mapping are distinct concepts, with web mapping not necessarily requiring a Web GIS.
