Caltrans Data Format  \n2.1  Drawing Types and Codes  \nA.  Drawing Types  \nCADD drawings for highway projects are categorized into two types: geographical and non-geographical.  \n1.  Geographical drawings are drawings wherein the graphical elements (lines, points and curves) are located by their on-ground horizontal locations (northing and easting coordinates) . Base maps are always geographical. Base maps are generally created by combining the Master Topographic files and the Master Design files. Plan sheets such as Layout, Drainage and Pavement Delineation are considered geographical because these plan sheets utilize base maps. Geographical plan sheets can be used by GIS mapping and other functional units to easily reference files located by the California Coordinate System (CCS) . All plan view sheets are to utilize and maintain the appropriate CCS.  \n2.  Non-geographical drawings are drawings wherein the graphical elements describe the spatial relationship of an object or planned construction without a direct relationship to specific horizontal coordinates (northings, eastings) . An example is a detail drawing for a drainage inlet. Project plan sheets like Typical Cross Sections, Construction Details and Summary of Quantities are not coordinately based, thus they are non-geographical. Drawings with a direct relationship to a horizontal or vertical location, such as Cross Sections and Profiles, are also considered non-geographical. In several cases, the listing in Section B categorizes a drawing as nongeographical when it appears to meet the definition of a geographical drawing because the drawings are cartographic rather than precise engineering drawings. A Title Sheet or Project Control Sheet is an example of this type of drawing.  \nB.  Project Plans Drawing Codes  \nThe various drawings used for roadway, landscape and electrical systems design are classified in this section by drawing type and are in the proper sequence for a final submittal of Project Plans. These drawings are those designated by the Plans Preparation Manual.  \nAll contract plans (except the Title Sheet) require a Plan Sheet ID (on the plan sheet) to facilitate the numbering of each type of sheet. Each type of  \nOctober 23 , 2017 Page 2.1-1  \nCaltrans CADD Users Manual Ch. 2.1 Drawing Types and Codes  \nplan sheet requires a print sequence code within the electronic name of the file. This will facilitate plotting plan sheets in the correct sequence. The Plan Sheet ID and print sequence code system are shown in the following table for the various types of roadway plan sheets.  \n\n| GEOGRAPHICAL DRAWINGS | NONGEOGRAPHICAL DRAWINGS |  |  |\n| --- | --- | --- | --- |\n| DRAWING NAME | DRAWING NAME | PLAN SHEET ID | PRINT SEQ.
