To support users in querying geographic databases we have developed a system that lets people sketch what they are looking for. It closes the gap between user and information system, because the translation of a user's question into a processable query statement is delegated to the information system so that a user can focus on the actual query rather than spending time with its formulation. This system paper highlights a set of interaction methods and sketch interpretation algorithms that are necessary for pen-based querying of geographic information systems. They are part of a comprehensive prototype implementation of SpatialQuery-by-Sketch, which provides feature-based and relationbased spatial similarity retrieval. KeywordsVisual user interaction, sketching, sketch-based querying, spatial information retrieval system.

“…A framework for image retrieval by contents was presented in [19], where images were associated with a tertiary represcntation of the three-dimensional imaged scenes according to symbolic projections. Intuitively, such association was motivated by the fact that, when considering images of 3D scenes, typically human beings perceive the scene depth and keep in mind a 3D view.…”

Retrieval by contents of images from pictorial databases can be effectively performed through visual icon-based systems. In these systems, the representation of pictures with 2D strings, which are derived from symbolic projections, provides an efficient and natural way to construct iconic indexes for pictures and is also an ideai representation for the visual query. With this approach, retrieval is reduced to matching two symbolic strings. However, using 2D-string representations, spatial relationships between the objects represented in the image might not be exactly specified. Ambiguities ari se for the retrieval of images of 3D scenes. In order to allow the unambiguous description of object spatial relationships, in this paper, following the symbolic projections approach, images are referred to by considering spatial relationships in the 3D imaged scene. A representation language is introduced that expresses positional and directional relationships between objects in three dimensions, stili preserving object spatial extensions after projections. Iconic retrieval from pictorial databases with 3D interfaces is discussed and motivated. A system for querying by example with 3D icons, which supports this language, is al so presented. The system fully allows the user to experience the sensation of directly interacting with reality with no intermediate mental processing.

Abstract-Conventional database systems are designed for managing textual and numerical data, and retrieving such data is often based on simple comparisons of text/numerical values. However, this simple method of retrieval is no longer adequate for the multimedia data, since the digitized representation of images, video, or data itself does not convey the reality of these media items. In addition, composite data consisting of heterogeneous types of data also associates with the semantic content acquired by a user's recognition. Therefore, content-based retrieval for multimedia data is realized taking such intrinsic features of multimedia data into account. Implementation of the content-based retrieval facility is not based on a single fundamental, but is closely related to an underlying data model, a priori knowledge of the area of interest, and the scheme for representing queries. This paper surveys recent studies on content-based retrieval for multimedia databases from the point of view of three fundamental issues. Throughout the discussion, we assume databases that manage only nontextual/numerical data, such as image or video, are also in the category of multimedia databases.
