Osage County, Kansas

Analysis Level and Transactional Level of Use of Cadastral Data


Note: This example includes references to some of the entities and attributes from the Cadastral Data Content Standard. If you are not yet familiar with the Standard's entities and attributes, you may first wish to look at the section on "Overview of the Model" in course Section 4, and at the Directory of Entities and Attributes.

The PRISM Project for Osage County, Kansas (Quoted text is reprinted from information provided by the Osage County Assessor's Office.)

"PRISM stands for Property and Resource Information Systems Management. PRISM is the joining together of information from multiple agencies through the use of one photobase. This project is a cooperative effort by the following agencies:

"The purpose of this project is to share information among agencies so that agencies are not individually maintaining similar databases. The photobase being utilized is the USGS NAPP digital orthophotography. This is 1 meter resolution gray scale aerial photography flown at 20,000 feet. The aim is to share GIS data layers amongst the partners in the project. For example, the NRCS provides soils and land cover layers, FSA provides crop field boundaries, and the County Appraiser's Office provides an ownership layer. This eliminates expensive and wasteful duplication of manual cartographic products. GRASS GIS software developed by the United State Army Construction Engineering Laboratory (USACERL) was used exclusively in the initial stages of database development. Additional interface elements developed by the USDA-NRCS were used in the intermediate stages. Currently, the Osage County Appraiser's Office is in the process of converting to ESRI GIS software products, specifically ArcInfo 7.1.1 and ArcView 3.0a. The hardware elements are Sun Microsystems Sparcstations running either Solaris 2.3 or 2.5 operating systems. In addition, the USDA - NRCS and FSA, as well as the Osage County Appraiser's Office, have been sharing the services of an employee, the PRISM Administrator. This individual acts as a liason between the agencies and performs computer system administration in both USDA and county offices."

Below is the northeast quarter of a section in Osage County, Kansas. "This particular quarter section has several rural residence parcels and a small lake, as well as as a railroad right-of-way. Attributes include parcel numbers and acreages. These are true ownership boundaries, which go to the centerlines of the road right-of-ways, as opposed to taxing unit parcels, which can be derived by combining this layer with the road right-of-way layer." quarter section Osage County

In the ArcView generated illustration at the left, acreages are shown in red, and parcel numbers, where illustrated, are shown in black. (For convenience, some of the parcel numbers were intentionally left off of the map to avoid overcrowding of information in the smaller parcels).

The acres information on the map corresponds to the Parcel Area/Parcel Area Quantity and Parcel Area/Parcel Area Unit entity/attributes in the Cadastral Data Content Standard, and the parcel number in the map corresponds to the Parcel/Parcel Local Label entity/attribute in the Standard.

Current work at Osage County focuses on completing parcel coverage of urban areas. Additional work focuses on combining soils, parcel, and land use layers for the determination of agricultural taxation. This combination of parcel level cadastral information with soils and land use represents an excellent example of the analysis level of cadastral data use (see Section 3: Relationships to Other Standards, topic on "Levels of Use").

While building the data layers represented here, staff in Osage County became aware of the Cadastral Data Content Standard. In the future, the organization would like to add attribute information which corresponds to the Cadastral Data Content Standard, most likely related to the Individual, Agent, and Parcel Transaction entities. When this occurs, their application will be able to function on the transactional level of cadastral data use, following dates, agents, parcels, and individuals through transactions.

As the corner points implied in this coverage are not derived directly from survey data, it cannot be said that the lines and polygons represent such survey related entities as Corner Point or attributes such as Corner Point/Monument Type. Like many users of the Cadastral Data Content Standard, Osage County has found that their data attributes correspond with part, but not all, of the Standard. They also find that while they will in the future be adding more attributes which correspond with the Standard, there are just as likely to be portions of the Standard which will not pertain to their purposes.
