Begin development of 3D models in selected study areas of the County. This effort will be vendor supported which will be responsible for initial data development and onsite training in ESRI CityEngine software. 3D models are anticipated to increasingly be used in countywide economic development and urban planning projects.
Continue the ongoing effort towards acquisition and development of critical public (both county and local) infrastructure datasets including public water distribution, storm water, and sanitary sewer systems. Important to a range of regulatory infrastructure management and public safety programs, much of this work requires coordination with local governments which have jurisdictional and maintenance responsibilities over these systems.
Continue data development efforts to support GIS-based applications in the Department of Social Services, Public Works/Traffic Engineering, Consumer Protection, Veterans Office, Environmental Facilities, and Parks, Recreation, and Conservation (PRC).
Continue proactive and collaborative efforts to obtain high-accuracy local government funded tax parcel datasets to support County government business programs as well as to republish through the County’s highly successful Tax Parcel Viewer applications.
Broaden the maintenance plan for enterprise GIS data which as of December 2014 contains approximately 1369 features classes and 39 raster datasets.
Spatial datasets are updated in a variety of ways including: (1) scheduled/
on-demand maintenance, (2) obtained from authoritative outside sources (i.e., local, state or federal agencies), or (3) updated as part of a supported business (departmental) process. Representing 20 years of investment, geospatial data continues to be one of the County’s most valuable assets.
Continue to support on-demand County GIS data distribution through download services via the Data Warehouse and from Mapping Westchester County. Downloaded data is accompanied with Federal Geographic Data

Shared Services
Beginning in the early 1990’s, Westchester County was one of the first counties in New York State to establish and implement geospatial programs that provided GIS outreach to local governments. Since then, Westchester County GIS has been successful in assisting local governments in building geospatial capacity through a variety of Shared Services initiatives. Early efforts by GIS staff under the Shared Services program focused on conducting user needs studies, data collection, providing assistance with desktop applications, and “start-up” implementation efforts. While many of these early efforts remain relative today, 2015 collaborative programs with local governments focus on strategic geospatial data and application development efforts. Priority data development efforts focus on critical infrastructure mapping, tax parcel mapping, and the delivery of authoritative base map datasets from the 2013 photogrammetric base map update. Leveraging the county’s built GIS hardware and software infrastructure, local governments can gain access to cost-effective web enabled GIS solutions for data access and viewing.
2015-2017 outreach is anticipated to continue with local governments with regard to holding technical advisory meetings, guidance on application and data development efforts, consultant selection, and maintaining the most valuable component of the County–local government geospatial relationship: Data Sharing.
During this same timeframe, it is expected requests for County GIS products and services will increase from the nonprofit sector and from the school systems as the use of geospatial technology in school system programs continues to grow.
GIS staff continues to advocate at both the state and federal level for grant programs supporting local government GIS. County GIS staff proactively represents County and local geospatial technology interests as part of the New York State GIS Association (www.nysgis.org). Staff routinely works in concert with consultants and GIS contractors on behalf of local governments to provide seminars and demonstrations.
Through the Shared Services program, Westchester County GIS staff is available to local governments, nonprofits, and community groups to provide:
• Geospatial map services
• Desktop GIS support
• GIS Project Management
• Data development and conversion
• Data hosting (County GIS Data Warehouse)
• User Needs Assessments
Page 30
• GIS training and education
• Consultant coordination and recommendations
Local government assistance is provided annually to nearly all municipalities in Westchester County.
Program Metrics
GIS system metrics provide a means to periodically measure various components of the County's GIS program. Such metrics are also commonly referred to as "key performance indicators". Within the GIS program, quantitative indicators focusing on Web activity, data downloads, software licensing, user training, internal application usage, annual data maintenance activities, and outreach to local governments, all provide key statistics and measurements assuring the program's accountability and demonstrating its value to County government and residents.
For the purpose of establishing baseline metrics to which future assessments can be compared, key 2014 GIS program metrics include the following:
