摘要

As a result of building a topological surfaced geodatabase for the test area, the paper discuses the investigation of modeling 3D surface data, and its fusion with other planinmetric modeled data, and storing it in a geodatabase, maintaining the special relationships of the data, its retrieval and representation methods, taking into consideration the quality aspects of the surface data, its validity, and its structured properties. In older days geographic, topographic, cadastral and thematic maps where produced to represent special information to the user, these maps in many cases contained surface information, using for example contour lines with specific thickness, interval, and collected with a special accuracy, coinciding with the grade of goodness of extracting these elements from the maps. Now a days maps still play an important roll in the information technology world, with an exceptional event of form and nature variation, altogether with its flexibility they became dynamically created by the GIS user from a distance through networks, to suit her/his or the client's requirements, thus creating digital thematic maps and reports, which means the source of this information (Geodatabase) has to be prepared with an up to date information, composing planimetric data and surface data altogether with their relationships stored, which shall regulate the way of retrieval, presentation and updating of the data and information, as well as quality aspects. A particular example is chosen for investigation, which uses an internet GIS application software that provides the user with online raster images, combined with the particular vector data selected from the map composer or using the inquiry system, retrieved from a Geodatabase. So what happens when the users requires surface information to be combined with their maps; this shall rise up the following investigation facts, and others: What kind of data categories complies with which surface style it can be shown. (Vector, Raster, contours, spot heights, 3D modeled surface, ..etc) What are the viewing aspects that shall be considered when adding these surfaces. (Scales, transparency, colors, thickness, interactions with other data, ..etc) Should the quality of the surface be indicated. (In many cases the accurate height information demanded, the quality may deceive) What is the validity of the information. (time of acquisition, changes happened in a particular area, ..etc) What are the relationships of the data, the surfaces should maintain in the Geodatabase.
