ABSTRACT
The spectacular advances computer science applied to
geographic information systems (GIS) in recent times has favored the emergence
of several technological solutions. These developments have given rise to
enormous opportunities for digital management of the territory. Among the
technological solutions, the most famous Google Maps offers free online mapping
dynamic exhaustive of the Maps. In addition to meet the enormous needs of urban
indicators geotagged information, we did work on this project
«Integration of an urban observatory on Google
Maps.»
The problem of geolocation in the urban observatory is
particularly relevant in the sense that there is currently no data (descriptive
and geographical) reliable on the urban sector; we must stick to extrapolate
from data old and obsolete. This helps to curb the effectiveness of urban
management to make difficult investment programming and to prevent the
acquisition of knowledge to make cities engines of growth. The use of a
geolocation tool coupled to the data would allow better monitoring of
indicators
Our project's objective is to develop an interactive map
server (WebMapping) which map layer is formed from the resources of the Google
Maps servers and match information from the field to produce maps of urban
equipment and infrastructure of a city data to the client's request
To achieve this goal, we will participate in a study of a GPS
location of strategic sites in our core sector (health facilities), on the
other hand, using information from the field, we will build a postgresql
database that will link the information from the field to map from Google Maps
via KML scripts and PHP appropriate.
We will limit ourselves in our work to the city of Douala
Cameroon with the sectors of health facilities with the possibility of
extension to other areas and other cities.
Keywords: Geographic Information System (GIS),
Thematic Mapping, Web Mapping, data mining, Google API.
