In practice, contour maps are scanned and vectorized, and after resampling in the target grid resolution, interpolation is performed. In this paper we demonstrate the limited accuracy of this process, and propose a high‐resolution processing method (without vectorization) that ensures maximum utilization of information in the source data. First, we discuss the mathematical background of thin plate spline interpolation, and explain the multigrid relaxation principle used to speed up convergence. After, we will show why fine tuning is necessary, especially when contour lines and elevation points are processed at the same time. Finally, our own contour thinning method that produces a significant reduction of elevation bias is described.&lt;/p&gt;</style></abstract><issue><style face="normal" font="default" size="100%">1-2</style></issue><work-type><style face="normal" font="default" size="100%">Journal article</style></work-type><notes><style face="normal" font="default" size="100%">UT: 000244002100004doi: 10.1080/13658810600816474</style></notes></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors></contributors><titles><title><style face="normal" font="default" size="100%">REST AND STRESS (ACETAZOLAMIDE) RCBF SPECT AND TRANSCRANIAL DOPPLER SONOGRAPHY STUDIES IN CEREBROVASCULAR DISORDERS</style></title><secondary-title><style face="normal" font="default" size="100%">EUROPEAN JOURNAL OF NUCLEAR MEDICINE</style></secondary-title><short-title><style face="normal" font="default" size="100%">EUR J NUCL MED</style></short-title></titles><dates><year><style  face="normal" font="default" size="100%">1992</style></year><pub-dates><date><style  face="normal" font="default" size="100%">1992///</style></date></pub-dates></dates><volume><style face="normal" font="default" size="100%">19</style></volume><pages><style face="normal" font="default" size="100%">594</style></pages><isbn><style face="normal" font="default" size="100%">0340-6997</style></isbn><language><style face="normal" font="default" size="100%">eng</style></language><issue><style face="normal" font="default" size="100%">8</style></issue><notes><style face="normal" font="default" size="100%">UT: A1992JL49600094</style></notes></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors></contributors><titles><title><style face="normal" font="default" size="100%">A TRANSITIVE CLOSURE ALGORITHM FOR A 16-STATE CELL PROCESSOR</style></title><secondary-title><style face="normal" font="default" size="100%">LECTURE NOTES IN COMPUTER SCIENCE</style></secondary-title><short-title><style face="normal" font="default" size="100%">LECT NOTES COMPUT SCI</style></short-title></titles><dates><year><style  face="normal" font="default" size="100%">1989</style></year><pub-dates><date><style  face="normal" font="default" size="100%">1989///</style></date></pub-dates></dates><pub-location><style face="normal" font="default" size="100%">AHO AV, 1975, DESIGN ANAL COMPUTERGUIBAS L, 1979, P C VER LARG SCAL IN, P509
