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. -
Challenges and Opportunities for Geospatial Integration Into
JOURNAL OF APPLIED GOSPATIAL INFORMATION Vol 1 No 2 2017 http://jurnal.polibatam.ac.id/index.php/JAGI ISSN Online: ISSN Online: 2579-3608 Challenges and opportunities for geospatial integration into ‘trotro’ road travel in Ghana Gift Dumedah Kwame Nkrumah University of Science & Technology, Kumasi, Ghana *Corresponding author e-mail: [email protected] Received: October 08, 2017 Abstract Accepted: December 04, 2017 Travel routing is vital for an efficient delivery of public and private services and Published: December 05, 2017 the movement of people and goods. In Ghana, the major nature of travel routing is through the ‘trotro’ system. The trotro system uses an automobile to move people Copyright © 2017 by author(s) and and goods along a prescribed travel route, with locally known stops where people Scientific Research Publishing Inc. get on and off the vehicle. 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. Keywords: GIS, Road travel, Trotro, Global Positioning System, GPS mapping, Travel routing 1. Introduction Ghana's road network and street addressing are growing economic and social rationale to address imperfectly mapped, with limited, inaccurate and this challenge. -
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. -
