The Impact of Positional Accuracy on the Computation of Cost Functions 330 $aThis book explains the concept of spatial data quality, a key theory for minimizing the risks of data misuse in a specific decision-making context. Drawing together chapters written by authors who are specialists in their particular field, it provides both the data producer and the data user perspectives on how to evaluate the quality of vector or raster data which are both produced and used. It also covers the key concepts in this field, such as: how to describe the quality of vector or raster data; how to enhance this quality; how to evaluate and document it, using methods such as metadata; 410 0$aGeographical information systems series. 606 $aGeographic information systems$xData processing$xQuality control 615 0$aGeographic information systems$xData processing$xQuality control. 676 $a526.0285 701 $aDevillers$b Rodolphe$0932556 701 $aJeansoulin$b Robert$0850729 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a996200193903316 996 $aFundamentals of spatial data quality$92098611 997 $aUNISA LEADER 00842nam a2200181Ia 4500 001 991004408823407536 008 251203s9999||||xx |||||||||||||| ||und|| 020 $a9788892852747 082 04$a725.7 245 10$aIl riuso degli edifici termali tra tardoantico e medioevo :$bnuove prospettive di analisi e di casi studio /$ca cura di Paolo de Vingo ; con contributi di Carla Maria Amici 260 $aSesto Fiorentino (FI) :$bAll'Insegna del giglio,$c2025 300 $a235 p. :$bill. ;$c31 cm 700 12$aAmici, Carla Maria 700 12$aDe Vingo, Paolo 852 $hLE001 725.7 DEV$oLE001N-20366$p2001000245062$g20$aLE001$mVM$t1$kloan$d22/10/2025$zPerformance 2026 - LE001 B.C. 017, 22/10/2025 - Doni/Cambi 2025-2026 912 $a991004408823407536 996 $aIl riuso degli edifici termali tra tardoantico e medioevo$94527673 997 $aUNISALENTO
