Essential mapping, charting, and visualization vocabulary (Aviation)
This vocabulary list will help you understand some of the concepts found in the mapping, charting, and visualization documentation.
Color separation
Color separation is a process in which a map or chart's colors are analyzed and separated according to unique color definitions.
Declination
Declination is the angular difference between true north and magnetic north, which changes over time.
Definition query
A definition query is a Structured Query Language (SQL) WHERE clause. The WHERE clause is appended to any SQL statement executed on the database. Use definition queries to concisely define the data you want to analyze and limit the number of features visible in a map.
Draft mode
Draft mode disables the display of an element in the page layout. The element occupies space on the page, but does not render.
Element
Elements are items in a map document's page layout. These include scale bars, north arrows, data frames, legends, logos, text, and other graphics.
Element library
An element library is a geodatabase that stores page layout elements. Element libraries contain four tables: ELM_CATEGORIES, ELM_ELEMENTS, ELM_PRODUCTS, and ELM_SOLUTIONS.
EPS file
Les fichiers EPS utilisent un langage de description de page PostScript permettant de décrire les objets vectoriels et raster. PostScript constitue une norme pour la publication des fichiers graphiques haut de gamme, la cartographie et l'impression. Les fichiers EPS peuvent être mis à jour dans des nombreuses d'applications de dessin ou placés sous forme de graphiques dans la plupart des applications de mise en page. Les fichiers EPS exportés avec ArcMap prennent en charge l'incorporation de polices afin que les utilisateurs qui n'ont pas de polices Esri puissent afficher correctement la symbologie. Les exportations EPS à partir d'ArcMap peuvent définir des couleurs grâce à des valeurs CMJN ou RVB.
GeoTIFF
GeoTIFFs are TIFF files with embedded georeferencing information. Embedded georeference information can include ellipsoid, datum, coordinate system, and projection. GeoTIFFs store one spatial reference per file.
Grouped element
A grouped element is a set of elements combined into a new element. A grouped element can be ungrouped into individual elements.
Masking set
Masks hide features, or sections of features. ArcGIS uses feature layers to mask other feature layers. Masking sets are stored information about ArcGIS masking settings. These sets can be recalled and reapplied to other map documents.
Overprint
An overprint is an area of overlapping colors that have blended to produce a different color.
Production PDF
Production PDF adds print production capabilities into PDF files exported from ArcGIS for Desktop. It supports all standard PDF export options from ArcGIS, with the added ability to create press-ready files for offset printing. Print production capabilities include Spot colors, overprint, color mapping, and colorspace conversion.
Representations
Representations are symbol information stored with geometry in a feature class. For more information, see What are representations?
Spot color
A Spot color is a named color associated with numeric values representing CMYK values and tint.
View
Views are map settings that can be saved to and retrieved from any geodatabase. They allow you to manage the properties of a data frame and layers so they can be reapplied at any time while allowing you to decide which current map properties to keep and which to override.
Visual specification
A collection of rules that manage representation symbology and label fields for many layers. You can apply these rules to multiple layers using the Calculate Visual Specifications tool.
Vvs file
A *.vvs file contains an exported view. Views are exported from the Production Symbology toolbar to a *.vvs file.
