GML ukuvula ifayela QGIS futhi Microstation

ngamafomethi GML ingenye yaziswa kakhulu onjiniyela nabasebenzisi GIS, kusukela ngaphandle nje kokuba ifomethi esekelwe izilinganiso ezifanayo yi OGC, iyashesha ukusebenza for ukudluliswa kanye exchange of idatha ku zokusebenza zewebhu.

I-GML ukusetshenziswa kolimi lweXML ngezinhloso ze-geospatial, isifinyezo sayo sisho uLimi lwe-Geography Markup. Ngalokhu kungenzeka ukuthumela kufayela lombhalo, ifayela le-vector ngisho nezithombe usebenzisa i-GMLJP2. Ingqondo yayo isuselwa encazelweni yesakhiwo se-node (okumelwe lapho) kanye nedatha uqobo, ukuze uhlelo lwe-GIS lapho lufunda ifayela le-GML liqale lihumushe iphrofayili yezimpawu bese lukhombisa idatha yezwe okuqukethwe lapho.

Isibonelo sesithombe sangaphambilini silingana nokuthengiselana kwe-cadastral yesondlo, lapho impahla ibonakala khona esimweni sayo sokuqala, futhi kufana nezinto ezimbili uma usuqedile, kanye nolwazi lwalo mnikazi we-alphanumeric.

Ungafunda kanjani ifayela le-GML usebenzisa i-QGIS.

Lokhu kulula njengoba isofthiwe yamahhala ingenza:

• Isendlalelo> engeza isendlalelo> engeza ungqimba wevektha> hlola

Lapha ukhetho lwe-GML lukhethiwe, futhi yilokho.

Ukuze ulondoloze ungqimba ku-QGIS njengefayela le-GLM, chofoza ngakwesokudla kokungqimba, gcina futhi ukhethe ukhetho lwe-GML.

Nakhu kuyadingeka ukuchaza ezinye izilungiselelo, isibonelo:

• Yisistimu yokubhekisela, okungenzeka kube yileyo esivele ichaze ungqimba.
• Ukubhaliswa kwabalingiswa, i-Latin 1 ilungele ukungabi nezinkinga ngama-accents nezinhlamvu ñ kumongo wethu waseSpanishi.
• Ukubaluleka kubalulekile, ukusebenzisa i-GML 3 kuyozinza kakhulu uma sifuna ukuba ifundwe ezinye izinhlelo noma isakazwe nge-Geoserver.
• Futhi, kufanele isungulwe uma sifuna ukuthi uhlelo lufakwe kufayela elifanayo noma ngokwehlukana. Uma uyifunda neBentley Map, kuyadingeka ukuthi lokhu kube ngokwehlukana, njengoba kuchaziwe kamuva.

Ungafunda kanjani ifayela le-GML nge-Microstation V8i

Lokhu ukusebenza kungenziwa kuphela ngezinhlelo zokusebenza ze-Microstation GIS, njenge-Bentley Map, i-PowerView, i-Bentley Cadastre, noma efanayo.

Endabeni yami, uma ngisebenzisa i-Bentley Map, kwenziwa kanje:

• Ifayela> Ngenisa> Izinhlobo Zedatha ye-GIS…

Njengoba ungabona, lapha ungase futhi ucele izingqimba zendawo okwenziwa njenge-Feature Feature Service WFS, Oracle Spatial, SQL Server.

Amafayela ohlobo lwe-SHP awahlali angenisiwe, ngoba avuleka ifomu lomdabu.

Endabeni yamafayela we-GML, inketho yokwengeza ifayela le-GML ikhethiwe ...

Ephaneli evela, kuzodingeka ukuthi ukhethe ukuthi ngabe ifayili lesikimu lihlukile yini. Ifayela le-Bentley schema laziwa njenge-XSD.

Futhi uma lokhu sekuqedile, chofoza ngakwesokudla isimiso se-Import1 futhi, bese ukhetha Hlela kuqala ukuze uyibonise noma Ngenisa ukungenisa kumephu.

Lapho uxoxisana nento nge inkinobho ethi "Hlaziya", umakwe njengezibuko ezimbili, futhi uthinta into, idatha ye-tabular ikhishwa kokubili njengetafula futhi njengekhodi ye-xml, njengoba kuboniswe esithombeni esilandelayo.

Ukuthekelisa ku-GML, inqubo efanayo ilandelwa:

• Ifayela> Thumela> Uhlobo lwe-GIS Data…

Kuzo zombili izinhlobo, kokubili i-QGIS ne-Bentley Map, kungenzeka ukuthi uhlele i-GML kalula njenganoma yiliphi ifayela le-vector, kanye nedatha yayo ye-alphanumeric.
