Taipei is the capital in Taiwan and nearly
fifty-five percent of the urban land is occupied by hillsides. However, the
increasing population and the sprawl of new houses across the hillsides have
resulted in some environmental problems and damages due to uncontrolled urban
development. The changing or destructive terrain and hillside condition make it
difficult for surveyors to collect terrain data and the visible evidence of
environmental destruction of land resources.
To reduce hillside
denudation and improve the querying and reporting efficiency of field data collection,
Geotechnical Engineering Office, Public Works Department, Taipei City Government
employed GIS technology to integrate the terrain data and hillside images taken
by satellites and then provide the officers with better hillside observation.
With the system, the forest patrols will be well informed if there is any
hillside destruction and then enabled to identify the reported location of the
hillside.
In addition, the
system helps the forest patrols access the reported information to explore
terrain data using smart phones, tablet, or computers and further update the
dynamic information about hillside condition through applications on devices.
Therefore, inspectors could fully comprehend and monitor hillside condition in each
region in real time.
Developed by Geotechnical
Engineering Office, the Taipei Hillside Remote Sensing Management System for
Reporting and Querying is consisted of Information Reporting System and Field
Investigation Management System. The systems can automatically generate
electronic reports and tables to help inspectors manage photos, record the hillside
condition, and upload investigation results in texts through handheld system.
In this project, the
server-based GIS software enables the office to publish map services and the
forest patrols to directly load maps and report real-time status of each
region. Besides, Field Investigation Management System, the custom mobile app,
is also created for Android devices to collect the hillside information of case
number, district number, coordinates of the reported location, hillside
variation images, topographic maps, etc.
Serving
as a geospatial data gateway, Taipei
Hillside Remote Sensing Management System for Reporting and Querying shows the
location of destructed hillside through satellite image analysis. Afterwards,
the reported location data can be sent to investigators’ mobile devices over the
Internet for further investigation data and photo updates more effectively.
In
the next phase, the system aims to establish a map website using SuperGIS
Server, the enterprise server GIS software, to ensure all the reported cases could
be well integrated and displayed on maps and the environmental condition in
each mountain could be effortlessly obtained for better preservation, saving
the loss and reducing disaster damage.
