Maricopa County Spatiotemporal Parcel Information System (PIMS) (2005)

Dr. Guo was the architect and developer of this highly integrated system built upon the Oracle Spatial, GeoMedia and ArcSDE technologies. PIMS has achieved two important objectives in addition to the significant productivity gains in parcel data acquisition, processing and distribution. The first is the automated maintenance of parcel spatiotemporal integrity so that parcel lineages that violate the spatiotemporal topology are rejected and current as well as historical parcels are stored seamlessly in a single layer. The second is the high confidence in data quality. The automated data quality assurance module raises over 30 different types of error conditions after comparing parcel information stored in several heterogeneous sources such as CAD files, Shapefiles, Access Databases and legacy database etc. PIMS has become the center piece of the Assessor’s mapping and GIS efforts in the County.

Maricopa County Roadrunner Application (2001)

Dr. Guo architected and led the development of the NACo award-winning project “Roadrunner.” The application represents a seamless integration of LRS-based GIS with the enterprise database and it is deployed throughout the Public Works Department in the County. There are two major innovations in the underlying technologies. The first is the use of SQL to quality-check the classic router-section systems built through ArcINFO and to generate the intersection table with address ranges. The second is the implementation of temporal dynamic segmentation proposed and defined in Dr. Guo’s doctoral dissertation.

Google Earth Integration with Transportation Improvement Program (TIP) for Maricopa County Department of Transportation (June 2006)

Dr. Guo architected and led the development of this three module system to enhance the TIP project review process by integrating spatial and non-spatial data through the use of GIS and the Google Earth technologies. An ArcGIS custom application allows the TIP administrator to define project area in ArcGIS and generate KML file. This module also allows the association of project documents with TIP projects. The second module is an intranet web site where users can select their TIP projects and launch Google Earth to view the project areas and access project related documents. The third module is an automated conversion tool that converts project documents into PDF files, which are then accessed by users through the Google Earth interface.
