GML kutsegula file ndi QGIS ndi Microstation

Fomu ya GML ndi imodzi mwa mawonekedwe omwe oyamikira ndi ogwiritsa ntchito a GIS amawayamikira, popeza kuti pokhapokha kukhala zovomerezeka ndi zovomerezedwa ndi OGC, zimagwira ntchito kwambiri popititsa patsogolo ndi kusinthanitsa deta kuntchito.

GML ndi kugwiritsa ntchito chilankhulo cha XML kuti chidziwitse geospatial, zomwe zimayimilira zimayimira Chijeremani Choyang'ana Chinenero. Ndizotheka kutumiza fayilo, mafayilo ndi zithunzi pogwiritsa ntchito GMLJP2. Malingaliro ake amachokera ku tanthauzo la mfundo zomangamanga (zomwe zikuyimira pamenepo) ndi deta palokha, kotero kuti pulogalamu ya GIS yowerengera fomu ya GML ikutanthauzira kale maonekedwe ake ndikuwonetsa deta zili mkati.

Chitsanzo cha chithunzi choyambirira chikufanana ndi katundu wothandizira kasitomala, zomwe zimaphatikizapo katundu pachikhalidwe chake choyambirira, komanso chimodzimodzi ndi zinthu ziwiri zikaphwanyidwa, ndizomwe zimapangidwanso.

Momwe mungawerenge fayilo ya GML pogwiritsa ntchito QGIS.

Izi ndi zophweka monga mapulogalamu aulere omwe angathe kuchita:

  • Lumikizitsani> kuwonjezera gawo> yonjezerani zitsulo> fufuzani

Apa, kusankha GML kumasankhidwa, ndipo ndizo.

chithunzi

Kuti muzisungira chingwe mu QGIS monga fayilo ya GLM, dinani ndondomeko yoyenera pazomwe mukusunga, sungani ndi kusankha mtundu wa GML.

Apa ndi kofunika kufotokozera zina zomwe mukukonzekera, mwachitsanzo:

  • Ndilobukhulo lofotokozera, lomwe lingakhale ili lomwe liri kale ndi wosanjikiza.
  • Makhalidwe akuthandizira, Chilatini 1 ndi abwino kuti asakhale ndi vuto ndi zolemba ndi makalata ñ mu nkhani yathu ya ku Spain.
  • Maonekedwe ndi ofunikira, kugwiritsa ntchito GML 3 kudzakhazikika kwambiri ngati tikufuna kuwerenga ndi mapulogalamu ena kapena kufalitsa kudzera pa Geoserver.
  • Komanso, ziyenera kukhazikitsidwa ngati tikufuna kuti pulogalamuyi ikhale yojambulidwa pa fayilo imodzi kapena padera. Ngati mukuliwerenga ndi Mapu a Bentley, amafunikanso kuti ikhale yosiyana, monga ikufotokozedweratu.

chithunzi

Momwe mungawerenge fayilo ya GML ndi Microstation V8i

Ntchitoyi ingangopangidwa ndi Microstation GIS, monga Bentley Map, PowerView, Bentley Cadastre, kapena ofanana.

Kwa ine, ngati ndimagwiritsa ntchito Mapu a Bentley, amachitika motere:

chithunzi

  • Foni> Import> GIS Deta Dongosolo ...

Monga momwe mukuonera, apa nanunso mungatchule zigawo zapakati zomwe zimagwiritsidwa ntchito monga Web Feature Service WFS, Oracle Spatial, SQL Server.

Maofesi a SHP alibe kanthu pamene amatsegula natively.

Pankhani ya mafayilo a GML, Fayilo Yowonjezera GML ...

M'ndandanda yomwe ikuwonekera, padzakhala kofunikira kusankha ngati fayilo yapadera ikusiyana. Fayilo ya Bentley schema imadziwika kuti XSD.

Ndipo mutatha izi, dinani ndondomeko yeniyeni pa ndondomeko ya Import1, ndipo sankhani Kuwonetsa kokha kuti musonyeze kapena Thirani kuti mubweretse ku mapu.

chithunzi

Mukamapempha chinthucho ndi batani la "Fufuzani", lolembedwa ngati magalasi, ndikukhudza chinthucho, deta yanu imakulira ngati bokosi ndi xml code, monga momwe chithunzichi chikuwonetsera.

Kutumizira kunja kwa GML njira zotsatirazi zikutsatidwa:

  • Foni> Kutumiza> GIS Data Type ...

chithunzi

Zonsezi, ndi QGIS ndi Bentley Map, ndizotheka kusintha mosavuta GML monga mafayilo aliwonse a vector, komanso data yake ya alphanumeric.
