Iimpawu zokukhetha iisombululo zeGIS / CAD

Namhlanje kuye kwaba ngumhla endibhalileyo ukuba ndibonise kwiklasi ye-cadastre ye-estate estate yaseBolivia. Esi sifundo sijoliswe ekuboniseni indlela yokukhetha iteknoloji yecomputer.

Lo mqondiso owusebenziseleyo, kwaye ingqalelo yam ukuhlalutya kwimeko esithemba ngayo ukuphumeza isisombululo.

umfanekiso

Ingxaki kukuba ukuba ufuna ukukhetha ithuluzi elilula lokubanjwa kwedatha kufuneka uqwalasele iinkalo ezingenanto yokwenza kuphela ngokukwazi ukwenza i-vectors, kodwa kunoko ukuzinza okunokuxhaswa njengoko kufuneka ngabasebenzisi bafikelela kuwo kumanqanaba ahlukeneyo kunye nenani labasebenzisi abakufuna iilayisenisi.

Phakathi kweminye imilinganiselo esiye siyicubungula, kwaye ubunzima bayo bunokuhluka ngokuxhomekeke kumxholo welizwe okanye ububanzi, phakathi kwezinye izinto kunokuqwalaselwa:

  • Ukungasebenzi
  • MiGangatho yeOGC
  • Ikhefu lokuFunda
  • Ukukhawuleza vrs. Inani labasebenzisi
  • Ukukhula kwendlela
  • Ukufumaneka kwe-interfaces yeprogram (API)
  • Iindleko ezipheleleyo

Emva koko siye sahlula umongo we geomatic ubuncinane kwiinqanaba ezithandathu kwaye walinganisa izinga lokubaluleka kweenkqubo zangaphambili kumaxesha ahlukeneyo. Ngamanye amabakala anokukhethwa uluhlu lweempawu ezizodwa abasebenzisi okanye iingcali eziphakamisayo kwaye zinikezwa ubunzima ukuze zihlolisise ngendlela yokuthelekisana neenzuzo kunye nokungalunganga kwezicombululo ezahlukeneyo:

1 Isigaba sokwakha

Kule nto, kulindeleke ukuba isisombululo sisebenze kwaye sisebenzise ukuvelisa kumgangatho ophezulu ngabachwephesha abavela kwintsimi, i-digitize, i-topology ecocekileyo, ukudibanisa ulwazi kunye nokusebenzisana nemifanekiso okanye iinkonzo zemephu.

2 Isigaba sokulawula

Kule nto kucatshangelwa, ukuba iinkcukacha ezivelisiweyo zingeniswa kwimigangatho efana nokwamkelwa kwisiseko sedatha okanye umphathi wefayile. Iinjongo ezifana nokugcinwa kwefomathi kunye neAPI ekhoyo kubaluleke kakhulu. Kwaye, kunjalo, izisombululo ezifunwa kule nqanaba lolawulo lweenkcukacha zilindeleke ukuba zisebenze kakuhle kwiindawo ezininzi zeendawo kunye nokukwazi ukugcina iinkcukacha zengxelo ezifana nejometri kunye neenkcukacha ze-raster, kunokuba zibe neendlela ezikhangayo.

4 Isigaba sokupapashwa, kule nqanaba kuqwalaselwa ukuba izisombululo zokwakha idatha ziye zineendlela zokuguqulwa kwimiqathango ye-ogc kwaye ukuba izixhobo zesevisi zedatha zinomgangatho wokwenziwa komntu ukwenzela ukuba zombini iinkcukacha zinokubanjelwa kwaye zikhangeleka zikhangeleka ngobugcisa.

5 Isigaba sokugcina, le nqanaba yesibini yokwakha, apho kulindeleke ukuba izixhobo zinakho ukhetho lokukwazi ukulungelelanisa ukufikelela kwabo ukugcinwa kweziphumo eziguqulelwe, ukugcinwa kwembali kwimbali kunye kwakhona, kunqabile ukwakhiwa ngokuchanekileyo. Ukuba kunokwenzeka ukhetho lokwenza isichaso esichaphazelekayo phantsi kwe-activex esebenzayo kwi-inthanethi ... ngcono.

6 Isigaba sokugcina, Ndibizile ukuba, kodwa ngokwenene yinqanaba lokufikelela kwiifowuni, apho abasebenzisi ngaphakathi kweziko lokufikelela, ukuguqula idatha, inkxaso kunye nokuvelisa iimveliso ezintsha. Nayi imfuno kwisisombululo se-CAD / GIS ayifumanekanga ukuzinza kwefomathi nomthamo wokuxhasa ukuguqulela, ngelixa izixhobo zokulawula, ezinokufumaneka ezininzi ekuphuhliseni, imigangatho yokhuseleko kunye nezixhobo zeseva zabasebenzisi.

3 Ukutshintshiselwa kwinqanaba, le nqanaba lesibini le papasho, apho kulindeleke ukuba isebenzise idatha kwi-xml, i-gml okanye ezinye iifom ezixhaswa yii-ogc, iimveliso esiyithemba ziya kusetyenziswa ezinye izisombululo ze-geomatic kodwa zibuye zibuye ziguqulwe. Oko kuthetha, ukukwazi ukuphazamisa phantsi kweemilinganiselo ze-geofumed, kubandakanywa ukhetho lwe-vector simplification ... yebo, i-geofumados efanelekileyo.

Nangona umgaqo kukusebenzisa isicatshulwa sezinto kwizisombululo ezahlukileyo kwinqanaba ngalinye le nkqubo, asimele sikhohlwe umongo wayo; ngoko siye sagqiba kunye umthambo msinya xa umthengi enkulu, nje ngeziko yomhlaba elizweni, ufuna ukuba amaphondo aqalise ngenkqubo ngokupheleleyo imeko ye malunga 20 amagcisa imveliso CAD / GIS, 3 ababhekisi phambili, abasebenzisi 75 intranet kunye nokubonisana ezininzi intanethi (sicime iindleko ngonyaka Oracle $ 30,000 iprosesa, uphuhliso software, kunye namaqela ukuphunyezwa nganye):

i-autocad map3d Yenza kunye nayo I-AutoDesk inokuhlawula i-$ 180,000, kunye nokulinganiselwa kwisigaba sokugcina iifasimali esifanele ukuzalisana namanye amaxabiso kunye nokusebenza kwezibonelelo zezixhobo ukulungiselela iinkcukacha ngokufanelekileyo nangaphantsi kweenjongo eziphezulu zokupasa.

bentley imephu Yenza kunye nayo I-Bentley inokuhlawula i-$ 210,000, kunye nokunciphisa kwisigaba sokutshintshiselwa, ukushicilelwa okuvela kwizinwele kunye nento kwinqanaba lokufunda

Esri Yenza kunye nayo ISRI ingaba yi-$ 300,000, kunye nemingcele kwisigaba sokwakhiwa kunye neendawo zokugcina iimpahla, oko kuza kuthatha ukuzaliswa kwamanye amaxabiso; ngaphandle kwendlela eya kuvela ngayo ukuba ilayisenisi ye-10 iyadingeka ukuba isongezwe i-$ 9,000

ezininzi Yenza kunye nayo Iintlobo zingadola i-$ 15,000, kunye nemingeni kwisigaba sokwakha, ikhefu lokufunda kunye nemfuno yabaphuhlisi bokuqala (nangona kukho onke amaninzi ukuphuhlisa). Ndiyacacisa ukuba kukho ezinye izisombululo eziphantsi kweendleko eziphantsi, kodwa ndiyisebenzisa le nto kuba ndizamile ngoku kwaye ndikumangalisile.

Kwimeko embi kukuba ndinayo i-$ 155,000 eyishiye ngaphezulu ukuba ndiqeshe iincwadi ezilungileyo kwaye ukuba ndidlala neelayisensi zexesha lokusebenza ndiyakulinga umgodi womthengi.

Kuyinto ehlekisayo ukuba phantse iphelele ingenziwa nayo software free, Pure GvSIG / Ingca, Postgre, IntelliCAD kunye nezinye imifuno ukuba ungakwazi ukuhlanganisa iqela systematization kweenkqubo, geofumados abaphuhlisi kunye nokuthembeka yokuthengisa le projekthi ... ukuba client akuyiqonda $ 700,000 ... I arhabaxa nzima kuba aphezulu ngayo inani labasebenzisi ungajongwa simahla okanye isoftwe zexabiso eliphantsi kakhulu.

Ngesishwankathelo, ndiyathemba ukuba ndivuselele iinqwenelelo zakho kwiisombululo zamahhala kunye nezindleko eziphantsi, nangona ixesha lifutshane kakhulu ukuba lingaphumi. Sichaze izigqibo ezifutshane ezimfutshane:

  • Itheknoloji efanelekileyo kukuba: "e no kuzinza"Kwimiba yehlabathi yophuhliso
  • Akunakuze kubekho iteknoloji "kuhle kuyo yonke into"
  • Umxholo "wezoqoqosho" kufuneka ucingwe ngokwemiqathango "umjikelo wobomi bobuchwepheshe"Kunye nokusebenzisana kwayo
  • Iinkqubo ezibhaliweyo (inkqubo) kwandisa umjikelo wobomi bobuchwepheshe
  • Akubona bonke abakulungele isofthiwe yehhala, ukuqala izicelo zikhethwayo "zorhwebo", Ngamava ocinga ngawo ngezicelo"indleko ephantsi"kunye nokuziphendulela"mahala"Okanye" uqobo "

Iimpendulo ze-4 "Iimpawu zokukhetha izisombululo ze-GIS / CAD"

  1. Sawubona, andiyazi ukuba ndiyakhumbula kakuhle kodwa le tafile ngeendleko zeeplani ezahlukeneyo, ndiyibonile ixesha elide ngaphambi kwaloo mhla evela apho, andiyazi ukuba uyihlaziye, okanye ndiyibukele kwelinye iphepha
