Map making may considered a form of art. It's digital from stratch, and more and more. Note:
- Maps are primarily utilitary objects. Some of them are really designed with artistic aims.
- Map design demands choces; a minima, show as ergonomically as possible the pertinent features of the map and its contents. This ergonomy leads to some treacheries with reality. In short, a kind of non-photo-realistic rendering.
- The need to show the altitudes has made mas somehow an ancestor of "3D".
- Colrs ant textures are intensively used for meaning (undergroud, administrative structures, etc.).
- Some major features see their side, their width at least, exaggerated, tyically the roads.
- Compared to a photography, a map has to be completed by data, textual (toponymy), iconic (symbols for a castle, a church, a capital city...). Artistic creativity is more at ease if there are comparatively few topographic data.

- Application of classes in Roxame (with some code), see Roxame Classes
- For image processing [Bres] deals with them on several places , see also [Zomorodian], [Cocquerez]. A "classification" distributes the pixels into classes, i.e. subsets with a same property (any property of interest, for instance light/dark, blue/red/yellow dominance...). Such a class does not consitute a connected subset, or region. Regions are identified by segmentation. But a classificaion may help a segmentation, as reducing the global complexity. Classification may also be used for creative effects. - Classification may be upgoing, hierarchical, with learning, mono- or multi-dimensional, with or without supervision. See [Cocquerez].

- Coded and digital are nearly synonymous. Read for instance Codes, la grande aventure ([Berloquin]), of which we don't resist to translate the conclusion, neighboring generative art: "In this sage, we are partners of the code. We are proud to be its masters, so having the right to create it, to use it, to ignore it or to reject if. But the reality is more complex. Actually, we create code rather easily, but the code can escape out of our control... Even worse, a new situation emerged in the 20th century: the code made a qualitative jump, getting independence and autonomy. Today, the code still depends on us for its creation and develpment, but its recent antonomu affords it to multiply itself and to act beyond our control abilities. Small "frankencodes", by the millions, swim freely in the virtual sphere of Internet and electronic communication. Are these last descendnts of Pythagoras codes a help or a danger greater even than the Planet warming?". ng] < Form+Code: In Design, Art, and Architecture, by Casey Reas, Chandler McWilliams and the graphic studio Lust.

- A lot of elements about advertisement in transmedia in [Rose].
- Works with an advertisement aim are generally poorly considered by artistic milieux, even when they live out of them. These works are rarely signed. Nevertheless, they are sometimes very innovative and technically perfect, since they are supported by generous budgets. Digital arts are no exception, has for instance showed the "Le futur a un passé" symposium organized at Ensad during Futurs en Seine (2012c.)
Main examples :
- TV commercial clips (also in cinema befor the film)
- commercial pages in printed press; sometimes, small masterpieces!
- in architecture, some public buildings, monuments, urban furniture, corporations headquarters
- advertisement objects
- many political, religious or simply festive events, with clearly more propaganda that art aims, are important forms of total art. It has bee son from the most ancient antiquity.
- even in nature, the most beautiful vegetal objects (flowers) or animal dance performanceperformances (love parades) are forms of commercials... which are appreciated even by the humans.

Content. We shall work our own synthesis, but let's start by Wikipedia definitions.
- Wikipedia: In media production and publishing, content is information and experiences that may provide value for an end-user or audience in specific contexts. Content may be delivered via any medium such as the internet, television, and audio CDs, as well as live events such as conferences and stage performances. The word is used to identify and quantify various formats and genres of information as manageable value-adding components of - Web content Wikipedia: Web content is the textual, visual or aural content that is encountered as part of the user experience on websites. It may include, among other things: text, imagess, ounds, videos and
- Content managemnet system. Wikipedia: A content management system is a computer program that allows publishing, editing and modifying content on a web site as well as maintenance from a central interface.
Such systems of content management provide procedures to manage workflow in a collaborative environment.
- The idea of cross-media or transmedia is based on the idea that a same content can be presented (or used, or combined) in several media, or channels, with the technical and industrial aspects of "channel". The multimedia, or multimodal system is more centered on the human senses used in the presentation or interaction.

- A region is said convex if, between any two points, there is a line semgent stricly included in the region. ([Bres] p. 319). Convex forms are easier to process than concave ones. Then, it may be practical to work on the convex hulls, which are the smallest convex form containing the original one.

- About graphic processing, this term says that the spectator feels an impression of realism.
Convolution: an example of application, using the Median function (here from Roxame): for each of the three components of a pixel, the chosen value is the median of values of the 9 pixels in the 3x3 square around it. Thus, you obtain a simplified image, slightly blurred, but frequently more pleasant that the standard bluring, which takes the average of these 9 values.

- the publication of techniques, methods, algorithms; in cinema, for instance, John H. Lawson (in his book The Creative Process, Hill&Wang, NY 1964) compares the abundant publication of the Russians (mainly Eisenstein) and the silence of Hollywood.
- the friendly cooperation in non-profit structures like fablabs.
Coordinates. [Foley], [Processing].
- Functions. See, among many, [Photoshop].
- Copy art. Art using photocopiers. Not properly digital, it is a forerunner of digital art by its use of advanced analog electronics. Did not last very long. Mainly 1980's. It has been practiced by Bruno Munari, an artist which had taken part in the Futurist movement.

- Positioning of a form by its corner (generally, high left forner) and its dimensions. For example, it is the default mode in [Processing].
- Corner pinning: positioning the four corners of an image to form any quadrilateral, upon which the original image will be anamorphosed. It may be used to obtain perspective effects. ([Brinkmann]p. 58).
- In music, a filtering system. It may be "graphical".
Correlation: a mathematical concept which can, somehow, be applied to images. A kind of similarity...
- [Bres] uses the term many times. [Gonzalez] p. 701-704: use of image correlation for pattern recognition.
- Histograms correlation is a segmentation technique [Cocquerez].
Cosmetic. "Cosmetic processing" ... [Gonzalez] p. 178 quotes the use of low-pass filters to soften an image, notably a face.
Cost. "The equivalent of a recording console which cost $150,000 in 1995 can now be had for about $ 2,000, owing to cheap digital memory, miniaturization, and the increasingly globalized economy". [Moorefield] p. XVII.

(*) Comments on Amazon about "Rethinking Curating"):
Such a specialized title could dissuade many people to read this book, in spite of its wider catching subtitle "Art after New Media".
But, in fact, curating becomes a central topic in the development of New Media, and so more of Transmedia, for at least two reasons.
1. In the traditional sites managed by "curators" (museums and showrooms), new media don't easily fit in the traditional presentation modes (painting on walls, sculptures on plinths) and storing facilities. They frequently require projectors, low light spaces, sound production means (with an appropriate separation from the other spaces). Some works call for interaction with the audience, with constraints on the floor around. Still more difficult, the perenniality of digital works remains a controversial 2. Even for traditional Art, curated places tend to become multimedia in order to offer their public a better presentation on the spot (headsets and more generally, locative media) and outside (websites).
Since the time this book was written (some three years when we write this comment, on fall 2012), the New Media scene has continued its explosive development and diversification. Tablets and smartphones have brought new kinds of problems and opportunities. Nevertheless, these daring views won't be obsolete before long, due to their depth and openness, would it be only the imperative demand to change and to cooperate between
