Maps and Diagrams. Their Compilation and Construction
~r HJ.Mo Mouse andHR Wilkinson MAPS AND DIAGRAMS 8 his third edition does not form a ramatic departure from the treatment of artographic methods which has made it a standard text for 1 years, but it has developed those aspects of the subject (computer-graphics, quantification gen- erally) which are likely to progress in the uture. While earlier editions were primarily concerned with university cartography ‘ourses and with the production of the- matic maps to illustrate theses, articles and books, this new edition takes into account the increasing number of professional cartographer-geographers employed in Government departments, planning de- partments and in the offices of architects pnd civil engineers. The authors seek to ive students some idea of the novel and xciting developments in tools, materials, echniques and methods. The growth, mounting to an explosion, in data of all inds emphasises the increasing need for discerning use of statistical techniques, nevitably, the dependence on the com- uter for ordering and sifting data must row, as must the degree of sophistication n the techniques employed. New maps nd diagrams have been supplied where ecessary.

Parents may arrange to meet with the counselor by calling the school's guidance department. COURSE DESCRIPTION The courses in engineering and technology provide opportunities for students to acquire skills and knowledge necessary for technological literacy, entry-level careers, and lifelong learning. Students learn Virginia’s 21 Workplace Readiness Skills within the content area. Those who are completing a two-year sequence have the opportunity to verify their knowledge of the workplace readiness skills through an industry assessment. This course provides students with the opportunity to learn more about the principles of architecture and related drafting practices and techniques. It provides helpful information for the homeowner and is beneficial to the future architect, interior designer, or homebuilder. Students use resource materials, standard books, and computers as they learn the general principles, practices and techniques of architectural drawing. The course includes designing residential structures and drawing plot plans, elevations, schedules and renderings. PREREQUISITE Basic Technical Drawing CERTIFICATION Students successfully completing the Technical Design and Illustration Program of Study will be prepared for the AutoCAD REVIT and or AutoCAD Architecture industry credential. STUDENT ORGANIZATION Technology Student Association (TSA) is a co-curricular organization for all students enrolled in engineering and technology courses. Students are encouraged to be active members of their youth organization to develop leadership and teamwork skills and to receive recognition for their participation in local, regional, state and national activities. -
Surveying Is the Art of Determining the Relative Position
CE6304-SURVEYING-I UNIT-I INTRODUCTION AND CHAIN SURVEYING DEFINITION: Surveying is the art of determining the relative positions of points on, above or beneath the surface of the earth by means of direct or indirect measurements of distance, direction & elevation. Plane Survey: Surveying which the mean surface of earth regarded as plain surface and not curve it really is known as plain surveying. A following Assumption are made: (i) A level line is considered a strait line thus the plump line at a point is parallel plump line at any after point. (ii) The angles between two such lines that intersect is a plain angle and not a sphere angle. (iii) The meridian through any two points parallel. (iv) When we deal with only a small portion earths surface the above assumptions can justify. (v) The error induced for a length of an 18.5 kms it‘s only 0.0152 ms grater than sub dented chord 1.52 cm. Geodetic survey : Survey is which the shape (curvature) of the earth surface is taken in the account a higher degree of precision is exercised in linear and angular measurement is tanned as Geodetic Survey. A line connecting two points is regarded as an arc. Such surveys extend over large areas PRINCIPLES OF SURVEYING Location of a point by measurement from 2 points of reference Working from whole to part. Location of a point by measurement from 2 points of reference There should be 2 points of reference say P & Q P,Q are the ground reference points and permanent points. -

Features and Design Intent in Engineering Sketches
View metadata, citation and similar papers at core.ac.uk brought to you by CORE provided by Repositori Institucional de la Universitat Jaume I Features and Design Intent in Engineering Sketches Raquel Plumed1, Peter Varley2, Pedro Company2 1 Department of Mechanical Engineering and Construction [email protected] 2 Institute of New Imaging Technologies [email protected], [email protected] Universitat Jaume I, Castellón de la Plana, Spain Abstract We investigate the problem of determining design intent from engineering sketches: what did the designer have in mind when sketching a component? Specifically, we consider the unidirectional reverse mapping from form features, as determined from an input sketch, to design features, representing the design intent present in the designer’s mind. We introduce a list of com- mon engineering form features. For each, we list which geometrical cues may be helpful in identifying these features in design sketches, and we list the design features which such form features commonly imply. We show that a reductionist approach which decomposes a diagram into form features can be used to deduce the design intent of the object portrayed in a drawing. We supply experimental results in support of this idea. 1 Introduction We aim to provide tools for design engineers who are already familiar with (and make good use of) the various features of state- of-the-art CAD packages, but who want the additional freedom offered by sketching when in the creative phase of designing a new product. Hence, we are interested in the interpretation of sketches of engineering components, both singly and in assemblies. -

Treatment of Diagrams in Document Image Analysis
Treatment of Diagrams in Document Image Analysis Dorothea Blostein, Edward Lank, Richard Zanibbi Computing and Information Science Queen’s University, Kingston Ontario, Canada, K7L 3N6 {blostein, lank, zanibbi}@cs.queensu.ca Document image analysis is the study of converting documents from paper form to an electronic form that captures the information content of the document. Necessary processing includes recognition of document layout (to determine reading order, and to distinguish text from diagrams), recognition of text (called Optical Character Recognition, OCR), and processing of diagrams and photographs. The processing of diagrams has been an active research area for several decades. A selection of existing diagram recognition techniques are presented in this paper. Challenging problems in diagram recognition include (1) the great diversity of diagram types, (2) the difficulty of adequately describing the syntax and semantics of diagram notations, and (3) the need to handle imaging noise. Recognition techniques that are discussed include blackboard systems, stochastic grammars, Hidden Markov Models, and graph grammars. 1. Introduction This paper concerns itself with diagram recognition, which is one component of document image analysis. Document image analysis involves conversion of a scanned document to an electronic form that captures the information content of the document [49]. The scope of diagram recognition problems is characterized by the following dimensions. • The diagram notation A great diversity of diagram notations are in use. Recognition techniques have been developed for a variety of notations, including engineering drawings [21] [22] [33] [35] [72], mathematics notation [1] [10] [17] [25] [28] [71], music notation [4] [9] [23] [36], chemical structure diagrams [46], circuit diagrams [14] [37] [51], and line drawings [13] [52] [62]. -
