篇1:大比例尺数字成图系统曲线的处理方法
大比例尺数字成图系统关于曲线的处理方法
大比例尺数字成图系统涉及到许多曲线处理问题,主要有两类,其中带有直线路段的公路、铁路构成的曲线定义为多义线,而河流主航道、地形等高线等属于没有直线段曲线成为曲线.两者的拟合方法与绘图处理平滑度不同,在成图系统中采用两种不同的`拟合处理方式:1.路径平滑插值(PSI);2.张力样条插值.

这篇文章主要介绍了python处理大数字的方法,涉及Python递归操作的相关技巧,需要的朋友可以参考下
本文实例讲述了python处理大数字的方法,分享给大家供大家参考。具体实现方法如下:
def getFactorial(n): “”“returns the factorial of n”“” if n == 0: return 1 else: k = n * getFactorial(n-1) return kfor k in range(1, 70): print “factorial of”, k,“=”, getFactorial(k)
运行结果如下:
factorial of 1 = 1factorial of 2 = 2factorial of 3 = 6factorial of 4 = 24factorial of 5 = 120factorial of 6 = 720factorial of 7 = 5040factorial of 8 = 40320factorial of 9 = 362880factorial of 10 = 3628800factorial of 11 = 39916800factorial of 12 = 479001600factorial of 13 = 6227020800factorial of 14 = 87178291200factorial of 15 = 1307674368000factorial of 16 = 20922789888000factorial of 17 = 355687428096000factorial of 18 = 6402373705728000factorial of 19 = 12164510040883factorial of 20 = 243290176640000factorial of 21 = 51090942171709440000factorial of 22 = 1124000727777607680000factorial of 23 = 2585738884976640000factorial of 24 = 620448401733239439360000factorial of 25 = 15511210043330985984000000factorial of 26 = 403291461126605635584000000factorial of 27 = 10888869450418352160768000000factorial of 28 = 304888344611713860501504000000factorial of 29 = 8841761993739701954543616000000factorial of 30 = 265252859812191058636308480000000factorial of 31 = 8222838654177922817725562880000000factorial of 32 = 263130836933693530167218012160000000factorial of 33 = 8683317618811886495518194401280000000factorial of 34 = 295232799039604140847618609643520000000factorial of 35 = 10333147966386144929666651337523200000000factorial of 36 = 371993326789901217467999448150835200000000factorial of 37 = 13763753091226345046315979581580902400000000factorial of 38 = 523022617466601111760007224100074291200000000factorial of 39 = 20397882081197443358640281739902897356800000000factorial of 40 = 815915283247897734345611269596115894272000000000factorial of 41 = 33452526613163807108170062053440751665152000000000factorial of 42 = 1405006117752879898543142606244511569936384000000000factorial of 43 = 60415263063373835637355132068513997507264512000000000factorial of 44 = 2658271574788448768043625811014615890319638528000000000factorial of 45 = 119622220865480194561963161495657715064383733760000000000factorial of 46 = 5502622159812088949850305428800254892961651752960000000000factorial of 47 = 258623241511168180642964355153611979969197632389120000000000factorial of 48 = 12413915592536072670862289047373375038521486354677760000000000factorial of 49 = 608281864034267560872252163321295376887552831379210240000000000factorial of 50 = 3041409313378043612608166064768844377641568960512000000000000factorial of 51 = 155111875328738228022424301646930321106325976986112000000000000factorial of 52 = 80658175170943878571660636856403766975289505440883277824000000000000factorial of 53 = 4274883284060025564298013753389399649690343788366813724672000000000000factorial of 54 = 230843697339241380472092742683027581083278564571807941132288000000000000factorial of 55 = 12696403353658275925965100847566516959580321051449436762275840000000000000factorial of 56 = 710998587804863451854045647463724949736497978881168458687447040000000000000factorial of 57 = 40526919504877216755680601905432322134980384796226602145184481280000000000000factorial of 58 = 2350561331282878571829474910515074683828862318181142924420699914240000000000000factorial of 59 = 138683118545689835737939019720389406345902876772687432540821294940160000000000000factorial of 60 = 8320987112741390144276341183223364380754172606361245952449277696409600000000000000factorial of 61 = 507580213877224798800856812176625227226004528988036003099405939480985600000000000000factorial of 62 = 31469973260387937525653122354950764088012280797258232192163168247821107200000000000000factorial of 63 = 1982608315404440064116146708361898137544773690227268628106279599612729753600000000000000factorial of 64 = 126886932185884164103433389335161480802865516174545192198801894375214704230400000000000000factorial of 65 = 8247650592082470666723170306785496252186258551345437492922123134388955774976000000000000000factorial of 66 = 544344939077443064003729240247842752644293064388798874532860126869671081148416000000000000000factorial of 67 = 36471110918188685288249859096605464427167635314049524593701628500267962436943872000000000000000factorial of 68 = 248003554243683059960099041856917158104739955367672371710738018221445712183296000000000000000factorial of 69 = 171122452428141311372468338881272839092270544893520369393648040923257279754140647424000000000000000

数字填图系统(RGMAP)在金厂矿区大比例尺填图中的应用
计算机辅助地质填图系统(RGMAP软件),通过建立PRB数字填图过程及其相应的数据模型,把地质数据采集的过程延伸到野外,真正实现了地学数据获取全过程的数字化,实现了地质填图从手工到计算机化的质的`飞跃.但该系统的研制初衷是为在区域调查中地质调查服务的,而对大例尺的填图尚未开展过研究.这里以在黑龙江省东宁县金厂矿区开展的1∶10 000大比例尺数字填图为例,总结出利用该系统在大比例尺数字填图中的主要方法步骤和注意事项.
