Online road utility authorization system utilizing GIS database
Linking the GIS and Task-Processing Databases
As described above, ROADIS possesses an integrated GIS database consisting of a highly
sophisticated Road Database (roads and topographical data) and Utility Databases that are
jointly maintained and managed by road administrators and utility companies. By linking task
processing data with this GIS database, this system realizes advanced functionality not
available in other systems.
- Utilizing the GIS Database for More Efficient Production of Application Drawings
In the case of conventional preparation of application drawings, it was necessary to search for
the area corresponding to the construction site in the application using the address, and then
perform various manual tasks such as physically clipping and pasting paper-media maps.
However, by facilitating easy extraction of base maps in ROADIS, the new subsystem makes
it possible to automatically retrieve maps based on address and route information that is
entered in the application form. In the case of the many applications for small-scale
construction work received every year, significant improvement in the production of
drawings has been achieved by the standardization and models of frequently used planimetric
and cross-sectional diagrams. (See Figure 2.)
- Utilizing the GIS Database for Project Management (State of Progress)
It is unnecessary to add the entry of special data because construction site coordinates that
were registered at the time of production of application drawings are registered in the
construction site database after conversion to the Road Database coordinate system. By using
these coordinate data, real-time retrieval and display of the dynamically changing state of
work progress (receipt of application, issuance of authorization, work commencement, work
completion, etc.) for designated projects can be performed. It is also possible to overlay and
display utility data. (See Figure 3.)

By linking to the GIS database, it is possible to obtain an accurate grasp of the state of
progress of the construction sites of multiple parties and immediately get detailed information
about each site, such as contact data for the construction company, etc. For example, by using
the information search function when handling resident complaints about excavation work or
when cracked pavement is discovered, response is smoother and faster, contributing to
greater citizen satisfaction with the service. Also, by using the Alarm conditional search
function, areas where work progress is unsatisfactory can be quickly identified and shown on
a map. In these and other ways, the system realizes high-precision project management that
could not be achieved with conventional paper-based maps and registers.
