Abstract
Mobile and wireless technologies have evolved rapidly in
recent years, especially the development of hardware devices,
such as PDA and Smartphone. Telecommunication service
providers, manufacturers and other developers have launch-
ed different kinds of services and applications in these mobile
devices. Mobile Geographic Information and Location Based
Service appear recently to help people to establish spatial
relationship with the surroundings. Map, which is a useful tool
to assist a person to define a position in a particular area, is
usually included in these systems. However, there is no
standard format of graphic presentation for map in mobile
devices. In this paper, the effective method was suggested for
the transmission of the geographic information acquired by
camera attached to a PDA such as position data, attitude
data, and image data in the wireless internet environment in
real-time.
Keywords : LBS(Local Based Services), Mobile Mapping,
Image Recognition, GeoComputing Platform, PDA
1. Introduction
It is no doubt that map is a useful tool to assist a person to
define a position in a particular area. With the mature
development in mobile devices such as PDA(Personal Digital
Assistant) and cellular phone, mobile GIS(Geographic
Information System) and LBS(Location Based Services)
appear recently to help people to establish spatial relationship
with the surroundings. As the bandwidth in wireless platform
is still much lower than that across Internet platform,
transform rate of data between server and mobile client is a
critical issue. Pixel-based raster map requires comparably
larger space storage to provide high quality of map detail and
does not support interactive functions. Also low resolution
screen display would degrade the convenience of using raster
map in mobile devices. As a result, vector display should be
introduced for describing spatial data in mobile devices.
Scalable Vector Graphics(SVG), which is a XML based
vector graphic display across Internet platform, is introduced
by the World Wide Web Consortium(W3C) in 1999. With
respect to the rapid development in mobile and wireless
technologies, W3C has defined the Mobile SVG standard and
specifications in the early of 2003. SVG consists of fruitful
painting, masking, clipping, filtering and styling
characteristics, various researches and potential applications
are carried out with the use of its extraordinary characteristics,
examples such as Interactive Web Mapping [1][2],
Multimedia Stroyboard [3], Geo-Spatial Education [4],
Computer Aided Design [5], etc.
Human Geographic has experienced continual changes since
the burgeoning of academic structure of geography in Germany
in the late 19th century. The emergence of spatial analysis which
appealed the enervation of traditional regional geographic brought
about the paradigm fever in human geographic. However,
paradigm suggested by spatial scientists disclosed lacks in the use
of its perception and application. [6].
To provide various information based on the location of
mobile user, LBS requires GIS functionality for mapping
user's current location and user's interest area through the
wireless internet. This location information is acquired by the
location determination technology. The geographic
information created with the location information is
represented on the screen of a portable device.[7],[8].
In this paper, we propose to use man's geographic
recognition in addition to a GPS for mapping objects. With the
help of man's ability of recognizing placement of objects and
geographical relations between objects, location information
given by a GPS is effectively compensated and utilized. This
method improves quality of a resulting map.
2. A Theoretical Review
2.1. Geographic recognition of human
Human does not stop recognizing his/her environment
including geographical environment. The way of recognition
is different from a GPS that provides 2 numeric characters,
latitude and longitude. Our research features the use of man’s
geographic recognition to obtain geographical relationships
between objects. Location information that is typical of human
recognition is as follows:
Distance
e.g. near, far
Direction
e.g. up, down, right, left
Placement
e.g. inside, outside, center
