Objectives of the Project
 Task 1: Design and prototype a geospatial semantic web
 Task 2: Tools for Geospatial Data Mining
 Both tasks are scoped within the allocated funding (50K for 6
months and 15K supplemental funding from UTD)
 We have obtained additional funding from UTD to carry our
activities to support and enhance the Project with Raytheon
Subtask 1.1 and 1.2 – Progress Report
Task 1: Accomplishments
Accomplishments
• Development of Geospatial Ontology – GRDF
• Use-case scenario of GRDF
• Single Interface Integration framework using
Semantic Web services (DAGIS)
• Algorithm for Dynamic Web services
Composition
• Implementation of Geospatial Operators (e.g.,
Between)
Task 1: Plans
Immediate Goals (Phase 1 : Oct 30th)
GRDF-based Semantic Dataset Development with
NCTCOG datasets and E-Plan
•
• SPARQL (Semantic Query Language) execution
interface over the datasets
• Future Goals (Phase 2 : January 1 ’07 – June 30 ‘07)
• Advanced QoS parameters for DAGIS
• Semantics-aware Access Control
Task 2: Accomplishments and Plans
Accomplishments: August 15-September 15
• Ontology based data mining using SVM techniques
• SPARQL (Semantic Query Language) execution interface over the
datasets
Plans:
Immediate: Until December 31, 2006
Enhance algorithms, prototype
Future (Phase 2 : January 1 ’07 – June 30 ‘07)
• Data Mining toolkit
Geospatial Data Integration: UTD Funding
 On-site chemical spill management
teams face a number of challenges
-
Multiple sources of data at a variety
of security levels
-
Overlapping areas of authority
Time-critical objectives
 We have recently completed a project to
integrate UTD’s E-Plan system with
CH2M Hill’s iCIT solution
-
Knowledge aggregator that
connects E-Plan’s secure chemical
reference web interface with iCIT’s
collaboration environment
-
Information is only made available
to authorized individuals

Some Related Activities in Geospatial Data
 UTD Joined OGC (Open Geospatial Consortium) – will be a
panelist for OGC’s Interoperability Day at the next meeting,
October 4, 2006
 Joined USGIF (GEOINT) and will be a member of their
academic curriculum and K-12
 Participating in UTD’s program in GIS
 Reading GEOINT research report by NGA to determine how
we can structure our research program
 Incorporate Geospatial data management units into our
courses for AFCEA
