Abstract:
Planimetric information for Cowlitz County consists of a comprehensive set of digital features stereo-digitized from five (5) ortho photography contracts flown in 1968(1), 1995(1) and 1996(3). The level of planimetric detail derived from these flights varies from project to project based on three contracted map scale accuracies of 1"=50' (1:600), 1"=100' (1:1200) and 1"=200' (1:2400). Typical planimetric features consists of natural and cultural features as water bodies, road improvements, building foot prints and utilities. The 1968 planimetrics that cover major portions of the cities of Kelso and Longview and the planimetrics that cover portions of Kalama City (flown in 1996) are more comprehensive than those generally produced in 1995 and 1996.
Purpose:
Planimetric data provides a threefold purpose: 1. To assist base mapping efforts by defining the location and boundaries of physical and cultural features 2. To assist in cadastral mapping by providing a means to interpret legal descriptions of deeds that often call out physically defined planimetric features and 3. To capture the location, type and height of various utilities to support various AM/FM(automated mapping-facility management) applications.

Data Quality Information

Attribute Accuracy:
Attribute Accuracy Report:
Typically, only cursory review has been conducted to check attribute accuracy globally beyond the QC/QA checks conducted by the contractor. Attribute test were limited to color coding the attribute, plotting the results and comparing against internal public record. More detailed checking is commonly conducted by either field checks, photos, and or office records and maps by jurisdictional entities only as the data is used.
Logical Consistency Report: Data set is topologically structured line, point and polygon data with nodes at all intersections.
Completeness Report: The data set is complete according to the scope of the original contracts for planimetric data. However the scope of work differs from project to project.
Positional Accuracy:
Horizontal Positional Accuracy:
Horizontal Positional Accuracy Report:
Relative horizontal positional accuracy for the planimetric information generated from the 1995 and 1996 ortho photography projects was contracted to meet the National Map accuracy standards for 1"=100' (1:1200) and 1"=200' (1:2400) map scales (+/- 21/2', +/-5' respectively). However, for 1995 and later, planimetric projects were developed utilizing state of the art photogrametric and survey techniques. Random testing of common planimetric derived data points to field derived GPS derived values indicated that the planimetric data was often far better than contracted National Map accuracy requirements.
Vertical Positional Accuracy:
Vertical Positional Accuracy Report:
Vertical accuracy for planimetric point data (1995 and later projects only) was contracted to comply with the National Map Accuracy for vertical data at map scale 1"=50'(1:600) 1"=100'(1:1200) and 1"=200' (+/- .5', +/- 1', +/- 2.5' respectively).

Process Step:
Process Description:
For 1995 and 1996 ortho photography contracts, cultural and physical features were stereo digitized to produce map accuracy of 1"=50" (1:600), 1"=100"(1:1200) and 1"=200 (1:2400) in major portions of the urbanized areas of Cowlitz County. Planimetric detail varies from project to project based on intended map scale of products. In general, the greater detail and larger map scales were selected to correspond to the most urban portions of the County, while the smaller scale (1"=200') mapping was selected for the more rural portions of the county.

Entity and Attribute Information

Overview Description:
Entity and Attribute Overview:
Typically, each planimetric feature is organized into ArcInfo(R) coverages with an associated attribute table. For each feature this table includes, at a minimum three unique codes, which are: a. an unique ID number, b. feature name and c. classification of the feature, where appropriate, according to a range of codes. Additionally an external Access (R) database contains various meta data pertaining to each ArcInfo coverage, that define such factors as reliability, source, and method.
