Spatial Communication - A Window into Business Data
Over the past twenty years, spatial technologies have penetrated almost every aspect of public administration and utility management, evolving from initial facility-based configurations into complex enterprise-based models that today communicate information to stakeholders throughout jurisdictions, serving as significant decision-support systems. The application of the technology to the world of private business during this period have, at best, been sporadic and dispersed, much as in the initial stages of development that were experienced in the early-nineties in local government. This paper investigates the scope for adapting the enterprise spatial model to serve an entire business need, skipping the steps of slow, restricted introduction of the technology into specific and easily recognizable areas of business application. The assumption is that, over the strategic period, benefits and costs of the planned approach will be far better optimized than gradual introduction over time.
Inventory of California Live Oak in the City of Santa Clarita Using LAR-IAC High Resolution Near Infrared and Color Photography: A Programmed Approach
The City of Santa Clarita contracted with Nag Inc. to utilize LAR-IAC four-inch resolution Near Infrared and Color digital ortho photography to
inventory California Live Oak trees within their jurisdiction. This species is protected under the City's Oak Tree Ordinance formulated along the guidelines provided by a similar ordinance of the County of Los Angeles. Development of any property within the City jurisdiction requires mitigation measures to compensate for any oak tree that may be impacted, an expensive operation, since the cost of mitigation for a heritage oak may exceed $100,000.

Spatial technologies provide a window through which data can be visualized. This can range from a simple chart generated by data in a spreadsheet to an intricate web-based application that serves an entire group of business functions. Correctly configured, it can provide critical decision support throughout an organization.
GIS Development for Stormwater Utilities to Meet NPDES Specification
(URISA 2002)
The National Pollutant Discharge Elimination System (NPDES) is a federal program to regulate discharge of pollutants into United States waters. The program provides for the collaborative participation of local governments in developing reporting standards for the maintenance and operation of stormwater utility systems. A Geographic Information System (GIS) solution is described for the management of effluent discharge throughout a typical local government jurisdiction. Stringent control of positional accuracy of facilities is maintained, utilizing Global Positioning System (GPS) ground survey and aerial photogrammetric mapping of drainage features, with parcels and stormwater easements representing a cadastral background to the system. A relational database design is implemented to manage the system and support NPDES reporting requirements. This paper addresses Public Utilities' management and technicians to provide a state-of-the-art automated solution to meeting NPDES reporting specifications.
Traffic Safety Analysis: A Spatially Enabled Technology (ESRI 2002)
A spatially enabled system for the management of traffic information with an objective to mitigate traffic hazards within a local government jurisdiction is described. The system involves coordinated activity between Police and Traffic Engineering Departments with reporting to the State Department of Transportation. The main components are Collision Reporting & Mapping, Archival, Analysis and Corrective Action to mitigate high-risk intersections and street segments identified by the system. Typical report formats are illustrated. The application combines data entry and report generation in Microsoft Access and spatial analysis in ArcGIS for improved traffic safety engineering and law enforcement.
Developing a Spatial Database to Meet NPDES Reporting Standards
(ESRI 2002)
The National Pollutant Discharge Elimination System (NPDES) is a federal program to regulate discharge of pollutants into United States waters. A spatial database, to support local governments in their effort to meet NPDES guidelines for maintenance and operation of their storm drain systems, is described. To viably meet horizontal accuracy specifications, GPS ground survey methods, 1"=100' scale planimetric drainage mapping, and topographic data at 1-foot contour interval are illustrated. Street centerlines, parcels, and storm drain rights-of-way provide a cadastral background to the system. A relational database design is implemented to manage the system and support NPDES reporting standards.
Engineering Accuracy in Utility GIS (URISA 2001)
This paper summarizes efforts to develop Utility GIS to meet stringent engineering specifications, and the lessons learnt during the implementation of utility projects at the Cities of Loma Linda and Downey, California.
Attaining Feature Accuracy in Utility Engineering GIS (ESRI 2001)
Accuracy is a measure of quality of an engineering utility GIS database. Schematic representation may suffice for small-scale maps (1=600' and smaller) and some system engineering modeling applications, but large-scale engineering mapping (1=100' and larger)
demands positional accuracy better than +2 feet. Stage-wise implementation gives precedence to layers of higher accuracy. GPS survey control, COGO cadastre input, aerial photography, analytical aerial triangulation, digital terrain modeling, rectified digital ortho photography, planimetry and topography is followed by precision digital input of utility layers. The final product is analyzed in terms of accuracy of different levels of base information utilized to reference it.
GIS Quality Assurance Data Acceptance Specification & Control (URISA 2000)
The quality of a GIS model depends on specification of its content and accuracy and the quality control methods used to measure adherence to these standards. Validation of the model involves checking for consistency between planimetric data and their corresponding physical features; cadastral data and source tax maps; adherence to graphics standards; and authentication of attributes for each of the entities. To keep costs reasonable, the checking process is automated to the greatest extent possible, and benchmarks established as to how good is good enough. Report summaries are indispensable tools to provide an overview of error status and trends. The quality control and assurance process is tracked from the initial product specification stage through the duration of the data conversion process and final product acceptance. Survey control and registration of associated themes are discussed in terms of vertical and horizontal positional accuracy within a consistent coordinate framework. Pre-marking of facilities and use of existing benchmarks to serve as a cross-reference between photogrammetry, cadastre, and utility facilities is investigated. Cartographic specification is analyzed in terms of conventional mapping and the comprehensive migration of information into a database format to ensure accuracy in spatial representation of feature entities and their attributes. The case of Fairfax County is cited: the GIS database comprising over 30 million graphic and attribute data elements, and features covering approximately 400 sq. miles. Both visual inspection and automated digital checking processes for quality control are described. Detailed reports of errors and error trends have been developed and samples included in the discussion. Time estimates for corrections were developed to support decision making on error management. This paper should be of interest to GIS and IS managers responsible for implementing or updating a GIS database, as well as staff involved in the data conversion process.
GIS Implementation at the City of Falls Church, Virginia (ESRI 2000)
The City of Falls Church,Virginia is situated a few miles southwest of Washinton D.C. bordering Fairfax and Arlington counties. Although only two square miles in area with 9,500 residents Falls Church has a local government organization and infrastructure similar to cities with much larger populations. This paper focuses on planning, design, and implementation of the City's GIS, and development of the first four applications: zoning, real estate assessment value analysis, property owner notification, and historical site management.
Successful implementation of GIS applications at the City of Falls Church within a relatively short period can be directly attributed to the commitment of City government to this new technology; effective management of the GIS implementation program by the City and its prime consultant; appropriate selection, support, and retention of qualified consultants throughout the needs analysis, systems selection, data acquisition, GIS database design- implementation and appliction development phases of the project; excellent coordination and cooperation among the various agencies involved; and the timely provision of needed information and support to the GIS application development effort.
