On June 18, Fortune published an article that quoted CEO Eric Gunderson, discussing the reasons for investing in a mapping company such as Mapbox: “Our backers are taking the long term approach. They understand how location is fundamental to every app and enterprise and are watching the entire mapping space turn upside down. They realise the future will include connected sensors and real-time data streams. This is about investing in the core infra- structure to power the future of location data.” In other words, Mapbox investors are looking at the company as something more than just a map - ping company – they realise that the future of mapping includes connected sensors and real-time data. Here we enter Internet of Things (IoT) territory, where in a distant future hardware and soft - ware will merge into one. The goal of Mapbox is not just to make good maps, but to infuse cor - porate data with geospatial and location-based context. Mapbox clients are described by Fortune as ´any business seeking to show patterns on a map’. What they’ll do, in other words, is big data analytics and mapping is only one piece of the puzzle. Gunderson put it this way: “We build great maps, but that’s just the canvas for anyone who wants to integrate real-time data and visualizations into their applications”. For some people, this large capital investment in Mapbox doesn´t come as a big surprise, but follows a trend. Mike Barlow describes in a recent O’Reilly publication called “The Last Mile of Analytics” that investors are gravitating towards enterprise software start-ups that cater to industry verticals (such as mapping). He differentiates between ´above-the-line´ technol - ogy and below-the-line’ technology in the big data market: the first refers to data-as- a-product, data tools and data software, the second to data infrastructure and platforms. The fastest growth is expected in the ´above-the-line´ segment. Mapbox announced their intention to invest in expertise, as well as strategic data sets. Earlier this month, they revealed a strategic relationship with online web mapping service MapQuest. The platform they´re building will transcend what is known as traditional GIS. Again, this is in line with a trend in IT where companies are “making the leap from platforms to tools (this is the subtitle of Barlow´s publication). It will be interesting to see how the company will evolve in the future – as well as reactions from competitors in the market.

A reliable geocoding system that can effectively return any location on earth with sufficient accuracy is desired. This study is motivated by a need for a geocoding system to support university campus applications. To this end, the existing geocoding systems were examined. Address-based geocoding systems use address-matching method to retrieve geographic locations from postal addresses. They present limitations in locality coverage, input address standardization, and address database maintenance.

  • Natural Area Coding Based Postcode Scheme
    International Journal of Computer and Communication Engineering Natural Area Coding Based Postcode Scheme Valentin Rwerekane1*, Maurice Ndashimye2 1 Department of Computer Science, University of Rwanda, Huye, Rwanda. 2 iThemba Labs, University of South Africa, Cape Town, South Africa. * Corresponding author. Tel.: +250 788 873 955; email: [email protected] Manuscript submitted March 7th, 2017; accepted June 23, 2017. doi: 10.177606/ijcce.6.3.161-172 Abstract: Traditionally, addresses were used to direct people and helped in social activities; nowadays addresses are used in a wide range of applications, such as automated mail processing, vehicles navigation, urban planning and maintenance, emergency response, statistical analyses, marketing, and others, to ensure necessities induced by new information technologies and facility developments. On top of addresses primary use, postcodes systems were developed to comprehensively provide a variety of public and commercial services. Postcode being an integral part of an addressing system, if well-established, a postcode system brings further social-economic development benefits to a country. This paper aims at designing a postcode based on the Natural Area Coding (NAC). The design focuses on designing a standardized postcode that can fit into any addressing scheme and be used for towns and cities of any shapes from structured cities to slums. Design considerations of a fine-grained postcode (easy for humans, efficient for computerized systems and requiring less or no maintenance over time to improve its efficiency) have proven to be difficult to realize. Therefore, in this paper a new logic is illustrated whereby these considerations are rationally handled while simultaneously allowing the postcode to give a sense of directions and distance.

  • Location Encoding Systems – Could Geographic Coordinates Be Replaced and at What Cost? Gogeomatics
    Stefanakis, E., 2016. Location Encoding Systems – Could geographic coordinates be replaced and at what cost? GoGeomatics. Magazine of GoGeomatics Canada. March 2016. Location Encoding Systems – Could geographic coordinates be replaced and at what cost? Geocoding is the process of converting a street address into a physical location that can be described with a pair of geographic coordinates. It is estimated that over 40% of the world population is physically disconnected because of lack of a street address. But even when street addresses are available, they are very often unable to describe the location. For example, locations inside parks or large facilities (e.g., stadiums or hospitals with multiple entrances) may be hundreds of meters away from the nearest address. The use of directions (such as “behind the main building find a storehouse; deliver the package at the right door facing the park”) instead of an address has become a common practice. However, this is usually ambiguous as it relies on local knowledge, while it cannot be interpreted automatically. Figure 1. UNB Campus. Three locations in Faculty of Engineering building. The street address to all of them is that of the Main Entrance: 15 Dineen Drive, Fredericton, NB. The wide spread of smartphones and mobile devices on one hand, and the extended internet accessibility on the other, have brought back the problem of geocoding in geomatics research and development. A geographic point location described by numbers (coordinates) – the geographic latitude and longitude as well as the height or depth – can be found more easily than ever by most of the users (as the smartphone becomes default equipment; I still resist and don’t have one!).

The trotro system is significant because Ghana's road network and street addressing are imperfectly mapped. Thus, this paper critically Open Access evaluates the research challenges and opportunities for the development of an integrated trotro geographic addressing system. The widespread trotro address assignment and the availability of geolocation technology on mobile phones, make the integrated trotro geographic addressing framework an inexpensive and a comprehensive approach. The key research questions that need investigation for the development of such an integrated geographic addressing system are identified, together with a critical review of the problem, and its research challenges and prospects.
