1. Term Project
Spatial Technologies in Infrastructure Construction and
Management
Presented by:
Srinivasa N
Instructor:
Dr. Hubo Cai

2.  To develop a data model to incorporate the
infrastructure components and management
 Model flexible enough for extension to other
entities/facilities
 Model capable of tracking changes and storing
historical data
 Scope – confined to Purdue University Campus

5. • Entities- Infrastructure facilities
• Features- Polygons, Lines, Points
• Attributes- IDs, Dates, Descriptions,
Dimensions
• Developed model represented as an ER model
with the relations given on the links connecting
different entities and features. The ER model is
obtained from exporting the data from
developed model into Visio and linking them
manually.

6.  Data like maintenance database maintained for
all the physical entities considered as
infrastructure.

8. • Determines
whether the
facility needs
a
maintenance,
and from it
decides what
kind of
construction
is needed.

9.  This set of fields
helps tracking
the progress of
the maintenance
of the facility.

12.  Use of
JunctionID’s to
determine the
references of
junctions and
nodes.

13. • Network
structure
showing
closed
loops of
roads
around
some of
the
buildings
.
