Sinthani deta ya CAD ku GIS ndi ArcGIS Pro

Sinthani deta inamangidwa ndi CAD pulogalamu mtundu GIS ndi chizolowezi chofala kwambiri, makamaka chifukwa zomangamanga amalanga monga zimachititsa chilumbachi, woyeza kapena kumanga kugwiritsira ntchito owona anamumanga mapulogalamu kapangidwe (CAD), ndi mfundo ya zomangamanga si zochokera kuyika zinthu koma kuponyera mizere, polygoni, magulu ndi malemba omwe ali mu zigawo zosiyana (zigawo). Ngakhale Mabaibulo atsopano a CAD mapulogalamu chikupitiriza chinthu wokonda mogwirizana ndi zinasokoneza makompyuta okhudza malo kufikako ngakhale pakati amalanga izi amafuna njira kusintha.

Chofunika kuti chipezeke: kuchotsa zigawo kuchokera CAD file kuti GIS, kenako kusanthula m'deralo Mwachitsanzo izi ife ntchito CAD file okhala ndi nkhani m'dziko cadastral, mudziwe hydrographic, mwachitsanzo mitsinje ndi nyumba ena anamanga.

Chimene muyenera kukhala nacho pamapeto pa ndondomekoyi ndi malo osanjikiza, mchenga ndi mzere wosanjikizika, mawonekedwe oyambirira a gawo lililonse amamvera mtundu wa chiyambi.

Deta ndi katundu wopezeka: fayilo ya CAD, pakadali pano dwg ya AutoCAD 2019.

Zotsatira Zowonjezera ndi ArcGIS Pro

Khwerero 1. Lowani fayilo ya CAD

Monga tawonera pamwambapa muyenera kukhala ndi .dwg, .dgn kapena .dxf file, (mtundu wa CAD), wasankhidwa kuchokera pa tabu Map chisankho Onjezani Deta, apo fayilo yoyenerera imasaka. Apa ikuyamba zovuta za kuwonetseratu kwa deta ndi ndondomeko ya fayilo, tinali ndi fayilo ya .dwg AutoCAD 2019, pamene wosanjikiza alowetsa mu ArcGIS Pro, dongosololi likuwerengera magawo a zigawo, koma mu tebulo lalingaliro likuwoneka kuti zigawo zilibe kanthu kalikonse, monga momwe tingawonere pazithunzi zotsatirazi.

Poyang'ana fayilo yapachiyambi, mu AutoCAD Civil3D ikhoza kuwona kuti ili ndi chidziwitso.

Musanayambe kukhulupirira kuti fayilo ndi yowonongeka kapena ilibe chidziwitso, m'pofunika kuganizira malemba omwe amavomerezedwa ndi ArcGIS Pro:

Kwa .dwg ndi .dxf

  • Kuwerenga, koma osati kutumizidwa: 12 ndi 13 ya AutoCAD
  • Kuwerenga molunjika ndi kutumizidwa: Mabaibulo AutoCAD 2000 v15.0, 2002 v15.0, 2004 v16.0, 2005 v16.1, 2006 v16.2, 2007 v17.0, 2008 v17.1, 2009 ndime 17.2, 2010 v18.0, 2011 v18.1, 2012 v18.2, 2013 v19.0, 2014 v19.1, 2015 ndime 20.0, 2016 v20.1, 2017 v21.0 ndi 2018 v22.0.

Kwa .dgn

  • Kuwerenga, koma osati kutumizidwa: MicroStation 95 v5.x, MicroStation SE v5.x, MicroStation J v 7.x
  • Kuwerenga molunjika ndi kutumizidwa: MicroStation V8 v 8.x

Monga mukuonera, pa nthawi ya kulemba phunziro ili, ArcGIS ovomereza alibe kuthandiza kuwerenga ndi deta katundu AutoCAD 2019, choncho palibe anasonyeza mabungwe pamaso, ndi chidwi kuti ArcGIS ovomereza silimanena zolakwika pa chophatikizidwa pa zigawo, ndipo sizimachenjeza kuti fayilo siyigwirizana ndi mavesiwo. Tsatirani mfundo ndi CAD dongosolo koma popanda deta.

Pambuyo pozindikira izi, zakhala zofunikira kugwiritsa ntchito TrueConverter kusinthira fayilo ya dwg, pakadali pano tazichita ku 2000.

Khwerero 2. Sinthani deta kuchokera ku fayilo ya CAD ku SHP

Zigawo zomwe mukufuna kufufuza zimadziwika, ngati deta yonse ya CAD ikufunika, tiyenera kutumiza chinthu chilichonse monga mawonekedwe, pamene CAD yasankhidwa, tabu ikuwonekera. Zida ZAD, mu zipangizo zomwe mungapeze njirayi Lembani Zolemba, gulu likuyamba kuwonetsera zolemba ndi zopereka; Chothandizira ndisankhulidwe chosankhidwa, pazochitika izi, ndi zotsatira zake zingakhale fayilo yapadera kapena geodatabase yogwirizana ndi polojekitiyo, pamene mukutsimikiza kuti ntchitoyo ikuchitidwa ndipo wosanjikizidwa adzawonjezeredwa pazomwe zilipozo .shp.

Khwerero 3. Fufuzani kusasinthasintha kwa kusagwirizana kosakwanira

  • Palinso mpata, umene umapangidwa mu mawonekedwe a polyline pamene GIS (mawonekedwe) achotsedwa. Pamene maonekedwe opangidwa amatha kuyambirira, mawonekedwe ndi nyanjayi pakali pano, ayenera kutembenuzidwa kukhala ma polygoni, malingana ndi mulandu ndi chofunika
  • Kwa mitsinje, ndondomekoyi imachitika kawirikawiri, komabe, zimapezeka kuti mtsinje waukulu ndi zowonjezereka zimapangidwa ndi zigawo zambiri. Kuti mulowe nawo, tabyo yasankhidwa Sintha, - chida Gwirizanitsani, ndipo izi ziphatikizeni zigawo zofanana ndi mtsinje waukulu, komanso gawo lirilonse lazigawo zake.
  • Mukhozanso kuona kuti muzomwe muli ndi mitsinje muli mzere umene, chifukwa cha mawonekedwe ake ndi malo ake, sali ozungulira awa, iwo amachotsedweratu, pokonza wosanjikiza omwe adalengedwa kale.

Nchifukwa chiyani polylines ndi zinthu zikuwonekera zomwe sizikugwirizana ndi geometries za ziwembu? Chofunikira ndichochokera ku pulogalamu ya CAD yoyeretsa zigawo za zinthu zomwe sizili zofanana, komabe cholinga cha ntchitoyi chachitidwa motere. Mwachitsanzo, fayilo yoyamba inali ndi block 3D ndi kutembenuka kwina, kuchokera ku fayilo ya AutoCAD Recap, pamene ikuyimira muzithunzi za 2D, imakhala polyline.

Ngati chikhululukiro chija chikufotokozedwa kale kuchokera ku fayilo ya CAD:

Kuti muchotse ma polygoni omwe alipo kuchokera ku CAD (1), mukhoza kuchita zotsatirazi monga momwe zinalili nthawi zonse ku ArcMap: batani loyang'ana pazowonjezera - Deta - Tumizani Zochitika, imasonyeza njira yotuluka ndipo mawonekedwe a polygon adzawoneka m'gulu lanu labwino.

Pankhaniyi, wosanjikiza zopangidwa polygons womwe poyamba anali mu kaundula CAD lolingana nyumba Komabe, pamene polylines ndi kuwunikira mu CAD choyambirira akusowa polygons awiri (2):

Zikanakhala kuti kupepesa kuchokera pa fayilo ya CAD kumadziwika:

Mu kabukhu Kakang'ono a CAD, chida Zikaikidwa ku Polygon, Chida ichi chikugwiritsidwa ntchito pamene pali chitsimikizo cha deta yochokera ku CAD, timawafuna pamapangidwe a polygon. Mukamaliza ntchitoyo, gululo latsegulidwa, komwe limapempha kuti liwone kuti ndi liti kapena zigawo ziti zomwe zidzasinthidwe.

  • Bokosilo likufufuzidwa ngati mukufuna kusunga zikhumbo za CAD, ArcGIS Pro yasunga malo angapo ndi kalembedwe ka mtundu wa deta.
  • Ngati mabungwewa agwirizanitsidwa ndi malemba kapena malemba a CAD, malemba awa akhoza kusungidwa mofanana.

Pankhaniyi, kuti fayilo ya CAD ndi "topological crap", Ndizochitika kale zomwe zinkatheka kutulutsa pulogoni imodzi, popeza chidacho sichizindikira mtundu wina chifukwa chimatseguka, ndiko kuti si pulogoni yokwanira. chifukwa ichi chosanjikizidwa chopangidwa ndi polygoni chasinthidwa ndipo chiwonetserocho chimalengedwa.

Pankhani ya malowa, mungasankhe polylines kuti apange ndi kugwiritsa ntchito chida kupanga mawonekedwe ndi polygon mtundu.

Chimachitika ndi chida ichi, ndikuti muyenera kukhala ndi chitetezo chokwanira cha zinthu zomwe ziri ndi polygoni; ngati ayi, idzapanga zochepetsera ndi zolakwika za topology, chifukwa zipangizo zowonjezerana zimagwirizana, monga momwe zasonyezera muzitsanzo pamene mukuyesera kusintha zinthu zonse za CAD ndi chida ichi:

Kulamulidwa, mbali Zina mwachinsinsi

Chotsatira chomaliza

Pambuyo pokonza njira zofananazo pazenera iliyonse tidzakhala ndi zotsatirazi:

Maonekedwe a mapangidwe a polygon

Mitsinje ya mtundu wa polyline

Zomangamanga mu mawonekedwe a ma polygoni

Nyanjayi mumapangidwe a polygon.

Tsopano tikhoza kugwira ntchito ndikuchita zofunikira, ndikuganizira kufunikira kwa chiyambi cha deta, zonse zomwe zimapangidwanso komanso kugwirizana kwake. Sakani apa zotsatira za zotsatira.

Phunziroli latengedwa kuchokera ku phunziro la 13 la Zovuta za ArcGIS Pro, zomwe zimaphatikizapo kanema ndi ndondomeko ya ndondomeko. Maphunzirowa alipo mu Chingerezi y mu Spanish.
