Land Parcel-Based Information Management
Land Parcel-Based Information Management ESRI Survey Engineering GIS Summit June 16 – 19, 2007 San Diego, California Frank Derby, PhD Penn State University Lehman, PA 18627
Land Management Objectives Making
of fundamental policy decisions about the nature and extent of investments in the land.
Operational
decisions made by land administrators such as surveyors, appraisers, land registrars
Land–related information systems Cadastral
information system Infrastructure information system Environmental information system Socioeconomic information system
Parcel-Based Information
The type of information which describes our relationship with a parcel of land.
All documents such as a map, deed, or record which depicts rights, interests, and responsibilities
Parcel –Based Information system A system for acquiring, processing, storing, and distributing information about land. Used to support decisions concerning the operational aspects of land management. Includes records describing property ownership, property boundaries, tax assessment, and other parcel related information within a jurisdiction and are typically managed by local government administrators. Requires a higher level of positional accuracy.
Parcel information Since the fundamental unit of land is the parcel, any information about the land should be acquired at the parcel level.
Parcel information describes our relationship with any parcel of land Who owns it, how it is used, what restrictions to the ownership exist, etc... Parcel information includes:
– documents, maps, records and any information that depicts, the extent of the parcel, the rights, interests, and responsibilities associated with the parcel.
Operational Activities Property conveyancing, mortgage and investment. Property assessment and valuation development and management of utilities and services Management of resources such as forestry, agriculture, minerals etc. Environmental impact assessments Monitoring land-based activities to ensure the best use of land.
Conveyancing The Deed is a public record of transaction involving a land parcel showing who owns what, where it is, what is its value, and other related information.
The Deed The Deed record contains:
The grantor and grantee Location and defines the boundary Legal description of the extent of the parcel Any rights, responsibilities, and restrictive covenants associated with the enjoyment of the parcel Easements and right of ways and other encumbrances The value of the parcel and any improvements.
Uses of Parcel-Based Information By local governments and municipalities to manage:
Community development Resource management Cultural equality Environmental balance
Local government Applications
Zoning
Tax Assessment
Land use Tax Coding
Graphical Data Sources Traditional land surveying methods
Optical Scanning of existing maps
Graphical Data Sources
Digitizing existing maps
Converting electronic maps
GPS data conversion
Three graphical data structures
Shapefile – Display faster in a view – Their format allows other software applications to read the data. – They do not have topology
Coverage – Uses combination of vector and attribute data in as topologically structured manner – Used to perform complex spatial analysis and to establish connectivity and adjacency between features
Geodatabase – Models people’s cognitive perceptions of objects in the physical realm as well as the way objects interact with each other. – It allows users to interact with objects through a framework of object oriented software classes.
