kweminyaka 10 bokufudukela iqonga geospatial - Microstation Geographics - Oracle Spatial

Lo ngumngeni oqhelekileyo kwiiprojekthi ezininzi zeCadastral okanye zeCartography, ngelo xesha i-2000-2010 edibeneyo ne-Microstation Geographics njengenjini yedatha yendawo, ngokuqwalasela izizathu ezifana nalezi zilandelayo:

  • Ulawulo lwe-arch-node lwaluye kwaye luqhubeka lusebenza kakhulu, kwiiprojekthi ze-cadastral.
  • I-DGN yindlela ekhangayo, iqwalasela inguqulo yayo kwifayile efanayo, engatshintshi kwiminyaka ye-15, ngokuchasene nezinye iifom apho siye sabona ezininzi iinguqulelo ezingahambisani nayo yonke iminyaka emithathu.
  • Kwi-2002, isofthiwe ekhululekile yayiyiphupha elide kulokho esinakho namhlanje.
  • Imilinganiselo ye-OGC yayingabalulekanga nakwi-software yangasese.
  • Iifayile ze-shp zazingaphelelwanga kwiiprojekti eziphezulu kunye neendawo ziseko zendawo zazingavaliwe kwizicwangciso ezingezizo eziye zonakalisa ukusebenza kweevava ... kunye nesiliva.
  • Ukuxhumeka kude kwakukho umxhasi xa kuthelekiswa nento esinazo ngoku.

Ngoko ke, ukuze kuphunyezwe GIS esekelwe scheme "CAD edityaniswe" yaba isisombululo iphila, nangona ezimqoka ngeenjongo ntetho enomtsalane amadini. I VBA API kwakukuninzi ukuya kwiprogram yesiqhelo zolawulo ezimfutshane uqhagamshele ProjectWise ukulawula iifayile emzimbeni kunye nokukwazi ukusebenzisa GeoWeb Umshicileli uhlalutyo lomhlaba ukusuka kwiseva, nangona ncwadi enyiniweyo ActiveX in Internet Explorer (leyo ngaloo nyaka yaba browser kuphela).

Le ngxaki ukuba wazivelela ngokuthe ngcembe yaye endaweni kudlula Umncedisi okanye ngaphezulu irobust ezongeziweyo iinguqulelo Geospatial ka ProjectWise, befuna ukusinda-GIS ukususela iifayile emzimbeni, ukuthatha amathuba ngokupheleleyo Oracle Spatial mvume kunye nokukwazi ukuphuhlisa. Ngoko ke umngeni wethu.

1 I-database: Postgres, SQL Server okanye i-Oracle?

Ngokukodwa, ndikhe ndakhetha kuqala. Kodwa xa ujongene nenkqubo yokuthengisana engekhekelekanga ngeenkonzo kodwa isebenza kakuhle, apho inxalenye yengcamango neengqibelelo ifana ne-PL kwisiseko sedatha, utshintsho kwi-database ye-OpenSoure ayilona yongxamiseko. Hayi, ngaphandle kokuba unengqondo ukuphuhlisa indlela entsha yeenkqubo ezingekho kwixesha elifutshane.

bentley map vbaAkunjalo nokwenza isenzo seTaliban ukunciphisa yonke into evumba i-proprietary. Ngoko ukuhlala kunye ne-Oracle isigqibo esisilumko, ukuba sisebenza kakuhle, ukuba ubungakanani kunye nemfuno bubanzi, ukuba luyilwe kakuhle, lukhuselwe kwaye ukuba inkxaso iyasetyenziswa. Umxholo kweso sihlandlo.

Ngoko oko kwakushiywe kukuba kukuphuhlise ukusebenza kweedatha ekufudlulelweni kule siseko, iinkonzo zepapasho kunye nezixhobo zokulawula idatha yenkcazelo ye vector.

Ukulawula iimbopheleleko kunye nabasebenzisi, ababekade belawulwa ngaphambili kwiProjekthiWise, ithuluzi lokumodareyitha lenziwe livumelekile:

  • Lawula abasebenzisi kunye neendima ezivela kwi-VBA eBentleyMap.
  • Ukunikezela kumsebenzisi ngamalungelo okulawula, ngokufanelekileyo kumasebe nakomasipala.
  • Nika ilungelo kwifayile yeefadastral nganye ngeprojekthi.
  • Unelungelo kwizixhobo ezikhoyo kwiKwakhiwa, ukushicilelwa, ukupapashwa, ukubonisana kunye neendlela zokulawula. Ngale ndlela, kuphela izicelo ezintsha ezidalwayo kwaye zibonakala kubasebenzisi ngokuphathelele indima ethile okanye isabelo.
  • Leli janeli lokungena ngemvume lenza lula ukuxakeka kwezinto eziqhelekileyo zeeprojekthi zeBentleyMap, okokuba ngokungena kwakho uza kubona umthi weentlobo kunye neempawu ezichazwe kwi-Geospatial Administrator.vba cadastre i-bentley imephu

Iphaneli yale nto ixazulula iingxaki zokungaqondi kakuhle kunye neengozi zabasebenzisi abatsha kwimisebenzi efana ne-Data Interoperability. Yiyiphi enye i-roll, kuba i-Bentley iguqula ngokwenene kwi-Oracle Spatial, eyinto emangalisayo kodwa inobungozi xa ungenalo ulawulo lomsebenzi.

2 Idatha: Ukufuduka kwe-DGN kwisiseko sendawo: I-Oracle Buider okanye i-Bentley Imephu?

Umngeni onomdla kakhulu kule nto, ukuba ukufuduka okulawulwayo kwakufuneka kwaye, ngokuqwalasela ukuba iifayile zeDGN zihlaziywe iminyaka engaphezu kwe-10 zinokuba neengxaki ze-topology - ubuhlanya bokwenene -.

Enyanisweni, kwakunjalo. Iingxaki eziphambili zeemephu zilapha:

  • Ukuguqulwa kwesalathiso kumda wefayili (icandelo okanye ummandla) kubonisa ukuba kufuneka kuguqulwe kokubili, kubandakanywa ukungalingani kwamanani kwiimeko ezifana nelo candelo kwicala elinye kodwa kummelwane ukuba loo mgca unamacandelo.
  • Kukho iifayile emva kokuthengiswa kwe-300 ukugcinwa kwimbali ye-DGN kungonakaliswa.
  • Akukho iingxaki ezintsonkothileyo kwikhabhinethi alawulekayo, njengaxa indawo esilala phezu komnye ummelwane kwenye fayile, kuba imali ayikwazi ukusonjululwa kwi mephu kuba oko bekuya kuthetha ukuba sihlolwe entsimini ukunqanda echaphazela wesithathu.
  • Izenzo ezimbi, ezifana nokufakwa kweemephu kwimilinganiselo eyahlukileyo, kule meko kukho amacandelo kwi-NAD27, nangona umgangatho wawunguWGS84. Kwiimeko ezinzima, ulungiso olwenziwe phakathi kwedatha evela kumaphulo ahlukeneyo, kumbindi.

Isisombululo sixhobo sohlobo lwe-Wizzard yokufuduka kwamanzi, okungahanjiswa ngamnye kwimephu, emininzi okanye nangomasipala (iholo leedolophu) okanye isebe.

ukufuduka kwendoda yokuthutha indawo

Ngokuyisisiseko eso sixhobo sithatha idatha yeprojekthi yeGeographics kwaye siyakhuthaza kwiimpawu zeBenltey Imephu, kwaye yenza ulandelelwano lwee-validation, njenge:

  • Ulwalamano olulodwa phakathi kwejometri kunye nedatha,
  • Ukuqinisekiswa kokungabikho kweziphindaphindiweyo,
  • Ukuqinisekiswa kwe-cent cent-centroid,
  • Ukuqinisekiswa kweemephu malunga nezinto ezingasebenziyo kwiziko ledatha,
  • Ukuqinisekiswa kwe-Topology ngokubhekiselele kwiibongozo ezikhoyo kwisiseko sendawo

Emva kokuqinisekisa, iphaneli ivumela ukongeza ulwazi ngeendlela ezinkulu, njengendlela yokulinganisa kunye nomgangatho wokulawula umgangatho wale datha.

Ekugqibeleni, ukuthumela database, ekugqibeleni adala ingxelo. Kulula kunokukwenza kukho a elula kakhulu, kodwa ekugqibeleni lihambisane ayilawulwa Oracle Spatial ixesha elide njengokuba ingaginyeki njengoko Bentley kunye nendlela yokubona ngamayelenqe ezintsonkothileyo okanye webali eziphezulu ezininzi.

3 Upapasho: Geoserver okanye iMapServer? IWayLayers okanye iLeaflet?

Umbukeli wakhiwa usebenzisa ii-OpenLayers kunye nezinye iifowuni. Ngethuba lokuqala emva kweminyaka eyi-10 yokunyamekela ukuphuhliswa kwengxenye yendawo, umbukeli omtsha wayebonakala efaka i-ActiveX ye-GeoWeb Publisher. Ikhowudi yeMephuFish isetyenzisiwe kwi-imbrication, i-geojson ukulawula umthi osisigxina, ukusuka kwiindawo ze-Geoserver ezikhonjwe kwi-OracleSpatial zahanjiswa.

4 Ukwakhiwa nokuhlela, ngqo kwi-Oracle Spatial. Bentley Imephu okanye iQGIS?

Eli elinye ibali. I-Bentley Imephu ishicilela isiqhelo kwisiseko sezithuba, esenza iimbambano xa zingayi kusebenza kunye neNkonzo yeeNkcukacha zeWebhu ye-Web (WFS). Ingxabano:

Indlela yokuyicombulula umgaqo wokungavumeli i-topology ifumaneka, ukuba ihleliwe kwaye xa ifuna ukuthumela ingxelo yokuba into iyazichaphazela?

Oku kusombululo ngokuguqulela kwangaphambili, ukulungiswa ngokuthe ngqo kunye nokuqinisekisa ukuba xa ukuthumela, ukuba kukho into ehlulekayo ukuguqulelwa ibuyiswe ngaphandle kokuba ukuthengiselana kuqedile kodwa kwimeko engaphumeleliyo.

Enye ingxaki efuneka ixazululwe yiyo yokungena kwedatha enkulu, kucinga ukuba abasebenzisi kufuneka bayeke ukusebenzisa i-Geographics kwaye babe neeprojekthi ezininzi eziphakamisa i-cadastre enkulu.

Oku kwakulula kuba kuphela isixhobo esifana nesasetyenziselwa ukudibanisa idatha kwi-Microstation Geographics eyenziwe, ukuququzelela ubunako beBentleyMap kunye nomncedisi olawulwa ngakumbi.

imephu egciniweyo yemephu ye-bentleey

Umfanekiso ubonisa ukuba aphuhliswa njani esi sixhobo, ezinye izinto awohluke, ezifana indalo kunye nobhaliso eziphezulu kunye kubandakanywe Puntoparcela njengoko uluhlu usebenziso kwimeko indlela yokulinganisa ezinye eziphezulu ukuhlangabezana umgangatho othile umgangatho.

Defintivamente le flow ukuba kulungile, njengoko abasebenzisi uyazi yintoni izixhobo ezisetyenziswayo kakhulu qho. Kwafuneka ukuba sitshintshe indlela esicinga ngayo phakathi indlela multiple features lolawulo tiered, nokukhuthaza iinzuzo ezintsha ukulibala akudala Microstation V8 2004, ezifana WMS, elubala kunye nokuqondwa zomthonyama DWG iifayile iinguqulelo lwakutshanje; oko akuthethi ukusebenzisana kunye KML, shp kunye GML ukuba astral.

Elinganayo, yenziwa izixhobo zokugcinwa kwe-cadastral, enokukhetha ukulungiswa ngokuthe ngqo kwiimo okanye ukunciphisa i-arc-node kwiimeko ezinzima.

5 Umxhasi koomasipala ngeGML. QGIS okanye gvSIG?

QGIS Kodwa ke, elinye ibali liza kuxela kamva.
