In this paper, we propose a method to determine the best regression axis to order the noisy points for curve reconstruction. The fundamental problem of the curve reconstruction is to order the data in most suitable way. We suggested a histogram based feature to be able to determine the goodness of the order for a regression line. The method developed by using the proposed feature tested on the some synesthetic data with different noise levels. This data was selected due to the eigenvector approach gave wrong results when obtaining regression line. The results showed that the proposed method is encouraging.

“…FURTHER READING Gold et al (1996) described and implemented a rapid polygon map digitizing system that resolved a significant industry bottleneck by using the labelled skeleton, and Gold (1997) used an edge-detection procedure, together with the crust and skeleton approach, to scan cadastral maps automatically. The dual is the context!…”

Labelled skeletons may be used to separate points that have additional information available, but more often this is not the case. In particular, for strings of points, where the distance between consecutive points is clearly less than the distance separating strings, it is often desirable to 'connect the dots' (to form the 'crust') -and also to define skeletons, as before, composed of portions of Voronoi cell boundaries, that separate the strings. To achieve this we need to go back to before the availability of digital computers, when (Blum 1967) was attempting to describe 'biological shapes' -the following five sketches were derived from his work.These were based on the idea of 'wave fronts' spreading out from the generators -which could be points or continuous lines ( Figure 126, Figure 127). Where the wave fronts meet we have Voronoi boundaries.

“…The project involved generalizing the LCMGB from 0.125 ha to 25 ha cells using semi-automated means. Gold et al (1996) describe a novel approach to forest digitizing. Essentially, they argue that the digitizing and building of polygon topology are expensive stages in many forest GIS.…”

now IJGI Science) marked its tenth anniversary by publishing a special issue (Vol. 10, no. 1) in honour of the founding editor Terry Coppock who did much to lay the foundations of present-day GIS, particularly in relation to rural land-use planning. A special issue of the Photogrammetric Engineering and Remote Sensing (PERS) journal on integrating remote sensing and GIS (Vol. 62, no. 11) commemorated the tenth anniversary of the first special issue of PERS dedicated to the same theme. The third special issue (of IJGIS, Vol. 10, no. 6) was on parallel processing in GIS, an important research area that is set to expand over the coming years. Several of the articles contained in these special issues are discussed in later sections. The year 1996 also saw the launch of Transactions in GIS, a new journal published by Geolnformation International dedicated entirely to GIS.The second milestone relates to the book entitled Principles of geographic information systems for land resources assessment by Professor Peter Burrough (Burrough, 1996). This book was published in 1996 in its second edition ten years on from the original. It was the first book on environmental GIS, and it remains an industry standard. In addition, three volumes in a new book series under the 'GISDATA' banner were published in 1996 (Burrough and Frank, 1996;Masser et al., 1996;Muller et al., 1996) as well as at least 20 other new books on GIS. It would serve little purpose to list them all, but the number
