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

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!).

Abstract Background The rapid dissemination of smart devices within the internet of things (IoT) is developing toward automatic emergency alerts which are transmitted from machine to machine without human interaction. However, apart from individual projects concentrating on single types of accidents, there is no general methodology of connecting the standalone information and communication technology (ICT) systems involved in an accident: systems for alerting (e.g., smart home/car/wearable), systems in the responding stage (e.g., ambulance), and in the curing stage (e.g., hospital).

  • Research for GEOCODE (Geospatial Entity Object Code) to Represent A
    Research for GEOCODE (Geospatial Entity Object Code) to represent a geographic point of interest (POI) and methods to evaluate or choose codes for an appropriate purpose 地理的座標を表現するコードシステムと、目的に応じたコードの評価お よび選択手法の研究 Naoki Ueda and Venkatesh Raghavan Graduate School for Creative Cities, Osaka City University, 3-3-138 Sugimoto, Sumiyoshi-ku, Osaka 558-8585, Japan ABSTRACT: A time-expression format such as “10:15” is common and everyone uses it naturally in daily life. In contrast, a location-expression format, such as “latitude and longitude,” are not used in daily life. This is because it is not convenient for people to remember and use. Today, a GPS device is built-into most mobile phones and many location-based services (LBS) are gaining popularity. However, we still use a descriptive explanation to show location and spend much time and cost to communicate a location to others. Therefore, in attempts to handle location as easily as time, various GEOCODEs (geospatial entity object code) have been invented around the world. All, however, are not yet in popular use. In this report, an overview of GEOCODE is introduced and some perspectives given to evaluate and choose an appropriate GEOCODE for a specific purpose. The author of this report is a GEOCODE researcher and an inventor of several GEOCODEs. KEY WORDS: GIS, LBS, Coordinates, GEOCODE, geospatial entity object code 概要：時刻を表す『10:15』のようなフォーマットは、ごく自然に日常生活の中で使われています。 これに対して、場所を表すフォーマット、例えば『緯度・経度』は日常生活で自然に使用できるよう な便利なフォーマットではなく、あまり利用されていません。 今日、ほとんどの携帯電話には GPS 機能が内蔵され、位置ベースサービス(LBS)が普及してきました。 しかし、我々は場所を表すには住所や説明的な文章を使うことが多く、他社に場所を伝えるときに大 変な労力を使っています。 まだ一般的ではありませんが、時刻と同じように簡単に場所を扱えるように、これまでたくさんのジ オコード（地理空間物を特定するコード）が世界中で発明されてきました。 本レポートの筆者はいくつかのジオコードの発明者でもあり、ジオコードの研究者でもあります。本 レポートでは、ジオコードの概要を紹介し、目的に応じたジオコードを評価・選択する上でポイント となる幾つかの「視点」を紹介します。 キーワード：GIS、LBS、座標、ジオコード 1.

Jiang, E. Stefanakis* Department of Geodesy and Geomatics Engineering, University of New Brunswick, P.O.Box 4400, Fredericton, E3B 5A3 Canada [email protected], [email protected] Commission IV, WGIV/7 KEY WORDS: RESTful API, Web Service, Geocoding, What3words, What3words Extensions ABSTRACT: Geocoding is a fundamental task of Geographic Information System (GIS) processing and analysis. It allows the transformation between a location reference (i.e., an address or an alphanumeric code) and coordinates, which is often an essential step when performing spatial analysis, mapping, and other geolocation related processes. Providing software functionality through RESTful APIs is a common practice in geospatial applications. Client programs are able to access or process geospatial data easily through a lightweight and scalable RESTful web service. Existing geocoding RESTful API providers include Google Maps Geocoding API, ArcGIS Geocoding REST API, MapQuest Open Geocoding API and what3words (w3w) Geocoding API. Extensions of what3words geocoding system have recently been proposed to overcome its limitation of fixed resolution and lack of consideration of the third dimension. This paper considers one of the extensions, the Quadtree Extension Model (QTEM) and introduces a RESTful API that provides operations for forward geocoding, reverse geocoding, single line and polygon encoding, and centre points encoding for a given area. The resources published by the web service could be implemented by software programs performing indoor and outdoor location referencing, location marking and path finding.
