I-GIS Manifold; Ukwakha kunye nezixhobo zokuhlela

Siza kuyinikela le posi ukuze sibone izixhobo zokwakha kunye nokuhlela idatha ngeeNinzi, kweli candelo izisombululo ze-GIS zibuthathaka kakhulu, ngelixa sinciphisa ukungagqibeki "okungaphelelanga" kwezixhobo ze-CAD okoko kugcinwa kwindawo yogcino lwedatha kufuna oko ukunciphisa umda wakho "ngokuchanekileyo" kwinani leendawo zokugqibela. Kucacile ukuba ngeenjongo ezibonakalayo izishumi ezibini zanele ... kwaye kwezinye iimeko zithathu.

Kodwa ungalindela kwizixhobo ezinesisombululo esincinci ukwenza kunye nokuguqula iijometri. Makhe sibone ukuba yintoni:

1 Izixhobo zokudala

Oku kwenziwa ngokuzenzekelayo xa ukhetha icandelo, kwaye oku kulandelayo:

umfanekiso

Isekwe ekudalweni kweentlobo ezintathu zezinto: indawo (polygon), imigca kunye namanqaku; umahluko ngokubhekisele kwi-ESRI ukuba icandelo linokuthwala iintlobo ezahlukeneyo zezinto ukuya kuthi ga iklasi lingaba luhlobo olunye lwezinto ezintathu.

Kukho ukwahluka kwendalo okuhamba ngale ndlela:

  • Faka indawo (esekwe ngamanqaku), elingana nomda we-AutocAD okanye ubume be Microstation
  • Faka indawo yasimahla
  • Faka umgca wasimahla
  • Faka umgca (ngokusekwe kumanqaku)
  • Faka imigca engafakwanga, elingana nomgca we-AutoCAD kunye ne-smartline ye-Microstation ngaphandle kokhetho kwiqela
  • Faka amanqaku
  • Faka ibhokisi
  • Faka ibhokisi esekelwe kwiziko
  • Faka isangqa
  • Faka isangqa esekwe kwiziko
  • Faka i-ellipse
  • Faka i-ellipse esekelwe kwiziko
  • Faka isangqa esekwe kwidatha (iziko, irediyasi). Okokugqibela kuyasebenza kakhulu kwi-GIS kuba isetyenziswa kakhulu kwimilinganiselo evela kwi-vertex okanye unxantathu ... nangona isilela ngenxa yokuba kungekho ndlela yongqinelwano kwi-snaps.

Ukongeza koku yiphaneli yokungena yedatha ngebhodi yezitshixo endibonisa kuyo post yangaphambili esebenze ngeqhosha "lokufaka" kwiqhosha.

2. Izixhobo ze-Snap.

Uphantse wanele, kwaye phakathi kwezona banazo kukhetho lokukhetha ezininzi ngexesha elifanayo ... umda osikelwe umda kwi-Microstation. Ukuvula okanye ukwenza inzame ingasebenzi okanye isebenzeibha yendawo"yeqhosha.

umfanekiso

  • Utyibilikiso kwigridi (amatyeli kunye nobude), ukuba igridi yenziwe yasebenza, ikuvumela ukuba ubambe njengendawo yokugcina intaba ukuhlangana kwendawo.
  • Snap ukuya kwigridi (xy idibene), efana neyokudlulileyo.
  • Qhoboshela iipuzzle
  • Qhoboshela imigca
  • Snap kwiingongoma
  • Qhoboshela izinto, oku kuyalingana ne "AutoCAD" ekufuphi, apho kukho nakuphi na ukubekwa kumda wep polygon okanye umgca.
  • Qhobosha ekukhetheni, lo ngowona miyalelo mhle, kuba ikuvumela ukuba ukhwebe kuphela kwizinto ezikhethiweyo, uvumela ukudibanisa okungentla.

Kuyacaca, ukuba enye indlela "yokungenelela", "indlela ephakathi" kunye "nendawo esembindini" ifuneka kakhulu, i-tangent ayibonakali iyimfuneko kwi-GIS, okanye "i-quadrant"

3 Izixhobo zokuhlela

umfanekiso

  • Yongeza i-vertex
  • Yongeza i-vertex kumgca
  • Cima i-vertex
  • Susa i-vertex kwaye ungazihlanganisi iziphelo
  • Sika icandelo
  • Cima icandelo
  • Ukwandisa
  • Nqunyiwe (i-trim)
  • Izinto zeCandelo

Izixhobo ezininzi ziyafuneka, njengokuhamba ngokuchanekileyo, parallel (offset) ...

4 Ulawulo lwendalo

umfanekiso

Esi sixhobo se Ndikhe ndathetha ngaphambili, evumela izinto ukuba zidibanise iikhrayitheriya zobumelwane; ukuze xa uguqula umda abamelwane bahlengahlengise kulungelelwaniso. 

Le yinye yezona zininzi zithintelo zeenguqulelo zangaphambili zeArcView 3x; I-ArcGIS 9x sele idibanise le nto nangona kubonakala ngathi ukuba kuphela iklasi Iphakathi kwe Indawo yedathangokunjalo Bentley Imephu kunye neBentley Cadastre.

Kukho isisombululo esibizwa ngokuba yi "topology factory" ekuvumela ukuba wenze ucoceko olubanzi kakhulu lwendawo, phakathi kwemigca engaphezulu, izinto ezigqagqeneyo, iigeometri ezikhululekileyo kunye nokukhetha ukuzisombulula ngesandla okanye ngokuzenzekelayo. ku "umzobo / umzi mveliso weetolgy"

 

 

Ukuqukumbela, ukuba nje ubuninzi abongezi zixhobo zongezelelekileyo, kuya kuba kuhle ukwenza uhlengahlengiso ngesixhobo se-CAD, kwaye uzise kuphela imilo okanye amanqaku kwi-GIS yokwakha apho. Kule nto, ukhetho lwe GvSIG ekuzameni ukuxelisa ezona zixhobo zibalulekileyo ze-AutoCAD zokwakha endaweni yokuthathela ingqalelo abasebenzisi.
