DEFINITION: This is advanced technical work in searching, compiling, drafting, and editing of maps and related illustrative materials using ink, scribing and/or computer assisted cartographic techniques.

An employee in this class works on complex maps and related illustrations characterized by the density of items to be depicted, the degree of accuracy required, the number of elements composing the map and related materials, and the extended period of time required to complete the assignment. Employees compile cartographic data, review and edit map products when required, draft of scribe maps, and prepare them for reproduction if required. In the Department of Transportation complex maps are determined by highway mileage, county size, scale, and congestion as found on Type 10 county maps such as Allegheny, Beaver, Berks, Bucks, Cambria, Chester, Delaware, Lackawanna, Lehigh, Luzerne, Lancaster, Montgomery, Philadelphia, Washington, Westmoreland, and York. Assignments are received with general instructions, and may involve the development and preparation of a map or series of maps and related illustrative materials. Employees work with considerable independence and initiative, but technical guidance is normally available. Lead worker responsibility may be exercised over other employees who are assigned for project production, training, or assistance. Work is reviewed by a cartographic supervisor who evaluates completed products.

EXAMPLES OF WORK: Compiles a variety of complex maps from cartographic source documents by searching and extracting necessary data from highway engineering plans, aerial photographs, straight-line diagrams, city maps, township maps, railroad reports, certified road reports, postal guides, aeronautical maps, field survey notes, computer listings, and other similar source materials, plotting the data, producing drafted or scribed copy, and editing the final product.

Uses standard ink drafting, special scribing instruments, or computer assisted cartographic techniques to compile, draft, and edit road networks, rail, air, and water features, off road culture and other technical data.

Uses a computer graphics workstation to draft and digitize map features, position labels and symbols, separate features by color and levels, and manipulate data for hardcopy plotting.

Constructs grid system on complex map productions by applying grid values and data obtained from standard plane-coordinate intersection tables and U.S.G.S maps.

Calculates enlargement and reduction factors for photographic reproductions such as reducing Type 2 to Type 3 maps.

Plots, inks or scribes highly congested cultural features and provides sufficient clearance in plotting or scribing complicated roadways and intersections.

Drafts or scribes overlays or scribe sheets to separate features or colors on maps or charts requiring close registration; masks and positions completed drafts and provides color keys and all necessary information for use by printer in reproduction phases.

Prepares final camera-ready copy of maps, graphs, charts, line drawings, and diagrams from rough drafts.

Interprets highway traffic statistics and plots or prepares complex maps, charts, and graphs depicting desired lines of travel for all stations in a traffic survey area.

Acts as lead Draftsperson for specific projects.

Resolves discrepancies and conflicting information on source documents.

Performs related work as required.

REQUIRED KNOWLEDGES, SKILLS, AND ABILITIES: Knowledge of cartographic preparation and production principles and procedures.

Knowledge of available data sources for map preparation.

Knowledge of algebra and trigonometry applicable to the work.

Knowledge of the methods of graphically portraying statistical data.

Knowledge of methods of printing multiple color maps and related materials.

Knowledge of cartographic application software for map production and geographic analysis.

Skill in plotting and inking or scribing congested cultural features on maps and related illustrative materials.

Ability to read and interpret maps, charts, survey notes, and similar source materials.

Ability to operate a computer graphic workstation (basic keyboard entries) for prolonged periods.

Ability to operate a process camera and related developing equipment.

Ability to perform or assist in performing computer scaling of digital maps for plotting.

Ability to create and manipulate digital text and symbol fonts.

Ability to execute cartographic application software for data analysis.

Ability to plan work and to proceed independently in accomplishing interrelated sequence involved in map preparation.

Ability to train and assist others in performing drafting and scribing work.

Ability to perform work requiring normal color perception and visual acuity.

Ability to interpret and follow map drafting specifications.
