also called Bézier curves. A mathematically precise and efficient method for drawing curves, shapes and lines using computer graphics software. Named after Pierre Bézier who discovered the mathematical formula for creating the splines . Bézier drawing tools are incorporated into many computer graphics applications, for example, Adobe Illustrator, Macromedia Freehand and Corel Draw multivariate statistical analysis that assesses the frequency of occurrence of a set of variables in relation to another set Microsoft Access term describing a method of summarizing large amounts of data using a variety of calculations on data in database tables Geographical Information Systems (GIS) is a computer system capable of assembling, storing, manipulating, and displaying geographically-referenced information in a Geographic Positioning Systems (GPS) is a technology that enables users to accurately locate their geographic position, typically from information transmitted by orbiting satellites and received by hand-held 3m wide wall and forward ditch, built across northern England, from near Newcastle on east to Willowford on west, during the reign of the Roman emperior, Hadrian (possibly c. 117 - 119 term referring to a method of data capture that involves the conversion of data in analogue form, such as maps and plans, into a digital form that is directly readable by a computer. 'Head-down' digitization refers to an operator moving a cursor, or as 'head-down', but 'head-up' digitization refers the digitization of scanned maps that are imported in a computer and digitised, or traced, by an operator using a computer mouse, or tablet name, invented during Renaissance, for Roman armour composed of bands of iron fastened together with buckles and strips of leather (Latin) statistical analyses that use two or more variables (e.g. a number of measurements on a pot) to assess for similarities and differences (e.g. between pots) and groups the objects accordingly (see Shennan practitioners, mainly American, of New Archaeology, introduced in the 1960s and popularised by Lewis Binford. Goals of New Archaeology are to 'explain the similiarities and differences in cultural behaviour' (see Trigger term referring to a series of steps followed to obtain a database design that allows for consistent storage and efficient access of data. These steps reduce data redundancy and the chances of data becoming inconsistent Visual Basic function in Access, used to replace null values in tables and queries with a zero, zero length string or other value Optical Character Recognition (OCR) is computer software designed to translate images of printed text (usually captured by a scanner) into machine-editable text management systems. In addition to the ODBC software, a separate module or driver is needed for each database to be accessed OLE is an abbreviation of 'Object Linking and Embedding', a proprietary Microsoft technology used to link its software products to database and other software applications term describing a feature used to represent areas. A polygon is defined by the lines that make up its boundary and a point inside its boundary for identification staff building usually placed at the centre of the fort, with offices and weaponry rooms. Opposite entrance was an assembly area and court room (Latin) term referring to a hand-held device used in association with a digitising table for accurately digitising maps, plans and aerial photographs databases that feature a relational data model that permits the designer to create a consistent logical model of the information to be stored. Data is processed and retrieved using SQL statements. Microsoft Access is the most commonly used relational database management system literally 'stamped clay', refers to type of red burnished Roman pottery that often had a maker's stamp in the base (Italian) Tagged Image File Format (TIFF) is a commonly used raster or bitmap graphics file format. A bitmap file represents images as a collection of pixels (dots) term describing a two-dimensional, planar co-ordinate system in which X measures horizontal distance and Y measures vertical distance. An XY co-ordinate defines each point on the plane. Relative measures of distance, area, and direction are constant throughout the co-ordinate plane Source.
