Ukuguqula idatha ye-CAD kwi-GIS nge-ArcGIS Pro

Guqula data zakhiwa nge GIS ifomati inkqubo CAD na unocwangciso eqhelekileyo kakhulu, ingakumbi ngenxa yokuba iinkalo zobunjineli ezifana mphandle, ucando okanye zokwakha zisasebenzisa iifayile kwakhiwa kuyilo iinkqubo zekhompyutha (CAD), kunye logic yokwakha akukho elihlenga kwizinto kodwa ukuhlabalala kwemigca, iipolgoni, amaqela kunye namabhalana akwiindawo ezahlukileyo (izalathisi). Nangona iinguqulelo ezintsha ze-software CAD kusiba into ebomini intsebenziswano iinkcukacha lwesithuba ndlela, uhambelwano phakathi kwezi nkalo usalindele iinkqubo zenguqu.

Yintoni ekulindeleke ukuba ifumaneke: ukususa ngokwemaleko ukusuka kwifayile CAD kwi-GIS, kamva ngokuhlalutya le ndawo, ngokuba lo mzekelo sisebenzisa ifayile CAD equlathe ulwazi lomhlaba cadastral, ulwazi lokuhlola amanzi, okt imilambo kunye nezinye izakhiwo kwakhiwa.

Oko ufanele uyenakho ekupheleni kwenkqubo kuluhlu lomhlaba, uluhlu lwemilambo kunye nobunqamle bezakhiwo, ifomathi yokuqala yolawulo ngalunye luthobela uhlobo lwemvelaphi.

Idata efumanekayo kunye nempahla: ifayile ye-CAD, kule ngxaki i-Dwg ye-AutoCAD 2019.

Ulandelelwano lweeNyathelo nge-ArcGIS Pro

Isinyathelo 1. Ngenisa ifayile yeCAD

Njengoko kuboniswe ngasentla kufuneka ube nefayili .dwg, .dgn okanye .dxf, (ifomathi ye-CAD), ikhethwe kwithebhu imephu ukhetho Yongeza idatha, kukho ifayile ehambelana nayo isesha. Apha uqala inkcenkceshelo yokubonakalisa kwedatha ngenguqulo yefayili, sinefayile ye .dwg AutoCAD 2019, xa umgca ungena kwi-ArcGIS Pro, inkqubo ifunda isethi yamacwecwe, kodwa kwitafile zembonakalo ibonakala ukuba iziqulatho aziqukethe nayiphi na into, njengoko inokubonwa kulo mfanekiso olandelayo.

Xa ubukela ifayile yokuqala, kwi-AutoCAD Civil3D ibonakala ukuba inolwazi.

Ngaphambi kokukholelwa ukuba ifayile yonakalise okanye ayinakho ulwazi, kuyimfuneko ukuba ithathe ingqalelo kwiinguqu ze-dwg zamkelwe yi-ArcGIS Pro:

Ngokuba .dwg kunye .dxf

  • Ukufunda, kodwa kungathunyelwa ngaphandle: 12 kunye ne-13 inguqu ye-AutoCAD
  • Ukufunda ngokuthe ngqo nokuthumela: Iinguqulelo AutoCAD 2000 v15.0, 2002 v15.0, 2004 v16.0, 2005 v16.1, 2006 v16.2, 2007 v17.0, 2008 v17.1, 2009 V 17.2, 2010 v18.0, 2011 v18.1, 2012 v18.2, 2013 v19.0, 2014 v19.1, 2015 v 20.0, 2016 v20.1, 2017 v21.0 kunye ne2018 v22.0.

.Dgn

  • Ukufunda, kodwa kungathunyelwa ngaphandle: MicroStation 95 v5.x, MicroStation SE v5.x, MicroStation J v 7.x
  • Ukufunda ngokuthe ngqo nokuthumela ngaphandle: MicroStation V8 v 8.x

Njengoko ubona, ngexesha lokubhala le kokufundisa, ArcGIS Pro akuthethi okwangoku ukuxhasa ukufunda kunye data ngaphandle AutoCAD 2019, ngoko akukho ukubonisa lwamaqumrhu emehlweni, kubalulekile ukwazi ukuba ArcGIS Pro akuthethi zibonise iimpazamo ngexesha iqhotyoshelweyo kumacandelo, kwaye ayilumkise ukuba ifayile ayihambisani neenguqulelo. Ukulayisha ulwazi ngolwakhiwo lwe-CAD kodwa ngaphandle kwedatha.

Emva kokuqaphela oku, kuyimfuneko ukuyisebenzisa TrueConverter ukuguqula ifayile ye-dwg, kulo mzekelo siye senze kwinguqulo ye-2000.

Isinyathelo 2. Guqula idatha esuka kwifayili ye-CAD kwi-SHP

Izicatshulwa ofuna ukuzithatha ziyachongwa, ukuba zonke iinkcukacha ze-CAD ziyadingeka, kufuneka sizithumele kuphela into nganye njengefomathi, xa iCAD ikhethiwe, ityhulwa ibonakala. Zixhobo ze CAD, kwizixhobo onokuzifumana kwinkqubo Khuphela I zixhobo, iphaneli ivula ukubonisa iiparitha zokufakelwa kunye neziphumo; entry umaleko ekhethiweyo kulo mzekelo iziza, kwaye imveliso enokwenziwa kwifayile eyahlukileyo okanye geodatabase ezinxulumene neprojekthi, xa nkqubo ukubaleka ekhuselekileyo kongezelelwa isiqulatho ifomati ezikroziswayo ipheyini ibe .shp.

Isinyathelo 3. Hlaziya ukuhambelana kweengongoma ezingaphelelanga

  • Kukho ne-gap, eyenziwa kwifomathi ye-polyline xa i-GIS (ifom) isuswa. Njengoko izimo ezizaliswayo zithatha ifomathi yangaphambili, iziqendu kunye nelagoon kulo mzekelo, kufuneka ziguqulwe kwiipolgoni, kuxhomekeke kwimeko kunye nemfuno
  • Imifula, inkqubo iqhutyelwa, nangona kunjalo, kufunyaniswa ukuba umlambo oyintloko kunye neentlawulo zawo zenziwe ngamacandelo amaninzi. Ukuzibandakanya nabo, ithebhu ikhethiweyo Hlela, - sixhobo Hlanganisa, kwaye oku kudibanisa amacandelo ahambelana nomlambo oyintloko, kunye necandelo ngalinye leentlawulo zalo.
  • Ungabona kwakhona ukuba kumgca oqulethe imilambo kukho umgca, ngenxa yokuma kunye nendawo yayo, ayikho yolo lucalulo, lupheliswa, ngokuhlela uluhlu olusele lusele.

Kutheni i-polylines kunye nezinto ezibonakalayo ezingafani nee geometri yeziqendu? I-Ideal ivela kwiprogram ye-CAD yokucoca iindawo zokungahambelani nezinto, nangona kunjalo, ngenjongo yalo msebenzi uyenziwe ngale ndlela. Ngokomzekelo, ifayile yemvelaphi wayekho 3D block kunye twist, ukusuka AutoCAD ifayile Ushwankathelo, ukuba emelwe 2D ukujonga uba Somzobo onamacala amaninzi.

Xa ububupolisa bebuye bahlaziywa kwiFayili yeCAD:

Ukukhupha iipolgoni ezikhoyo kwi-CAD (1), unokwenza le nkqubo elandelayo njengoko yenza njalo kwi-ArcMap: iqhosha lasekunene kwinqanaba - Idatha - Ukuthumela izinto, ibonisa indlela yokuphuma kunye nomfanekiso we-polygon uza kubonakala kwipaneli yakho yomxholo.

Kulo mzekelo, umaleko eyenziwe yeepolygons ekuqaleni kule fayile CAD ehambelana izakhiwo, Noko ke, xa polylines kwakhona kwi CAD yokuqala ilahlekile eneepoligoni ezimbini (2):

Kwimeko apho iifolongo ezivela kwifayili ye-CAD ziyaziwa:

Kwi-CAD Layers tab, isixhobo Faka kwiPolygon, esi sixhobo sisetyenziswe xa kukho ukuqinisekiswa kwedatha evela kwi-CAD, sifuna kwifomati ye-polygon. Xa uqhuba inkqubo, iphaneli ivuliwe, apho icela ukuba ichaze ukuba yeyiphi na iindawo okanye iindawo ezizoguqulwa.

  • Ibhokisi ihlolwe ukuba ufuna ukugcina iimpawu zeCAD, i-ArcGIS Pro igcine inani leenkalo ngesitayela esithile salolu hlobo lwedatha.
  • Ukuba amaziko anxulumene nezichasiselo okanye iilebula ze-CAD, ezi mabalethi zingagcinwa ngendlela eza kwenziwa.

Kule meko, iFayili yeCAD "ukuphosa", Ngenkqubo yangaphambili kunokwenzeka ukukhipha ipoloni enye, ekubeni isixhobo asiqapheli esinye isakhiwo kuba sivulekile, oko kukuthi, asiyiyo ipolgoni epheleleyo. ngokuba olu luhlu oludalwe ngama-polygons luye lwahlelwa kwaye uphawu luyadalwa.

Kwimeko ye-lagoon, ungakhetha iipollines ezenzayo kwaye zisebenzise isixhobo sokwenza umlo ngefomati ye-polygon.

Kwenzeka ntoni ngale sixhobo, kukuba kufuneka ube nokukhuseleka ngokupheleleyo kweziphi iipolgoni; ukuba kungenjalo, kuya kuvelisa ulwahlulo kunye neephoso ze-topology, kuba iinkampani zobunqamana zidibanisana, njengoko kuboniswa kumzekelo xa uzama ukuguqula zonke izixhobo ze-CAD ngesi sixhobo:

Ukulawulwa, kwiindawo ezizenzekelayo eziyimfama

Isiphumo sokugqibela

Emva kokuqhuba iinkqubo ezihambelana noluhlu ngalunye siya kuba nale ilandelayo:

Ubume beenjongo kwifomati ye-polygon

Imilambo kwifomati ye-polyline

Izakhiwo kwifomathi yefomathi

Igoboni kwifomati yefolda.

Ngoku sinokusebenza kwaye senze izihlalutyo ezifunekayo, ngokuqwalasela ukubaluleka kwemvelaphi yedatha, zombini ifomathi kunye nokuvumelana kwayo. Landa apha umphumo wokuphuma.

Esi sifundo sithathwe kwisifundo se-13 Inkambo ye-Easy ArcGIS Pro, equka ividiyo kunye nenyathelo ngesinyathelo. Ikhosi iyafumaneka ngesiNgesi y en Español.
