- Abstract
- This paper presents GSQL (Geographical Sketch Query
Language), a sketch-based approach for querying geographical databases
based on the GeoPQL query language. Geographic information is
intrinsically spatial and can be conveniently represented using a bidimensional
space. Graphical User Interfaces and Visual Languages can be
used to satisfy this need. However, the growing availability of sketching
tools (PDA, digital pens, etc.) enables a more informal and natural user
interaction. Sketch based interaction is very effective. Each user can easily
sketch his/her geographical query by drawing it, erasing and modifying its
parts and highlighting the query target. A query is the expression of the
configuration of the expected result. Sketch recognition and query
interpretation (and solution of their ambiguities) starts from a contextindependent
approach and uses the characteristic application domain
information. Context-independent sketch interpretation uses spatial and
temporal information related to the sketching process. Context-dependent
sketch interpretation uses geographic domain information to solve the
remaining ambiguities and correctly interpret the drawing and query. An
analysis of the ambiguities characterising object sketching in the geographic
application domain and their possible solutions are presented herein. Each
query identifies the set of geographical objects involved and the target; the
query interpretation must unambiguously identify the set of its results. (literal)
