Qhib ntawv GML nrog QGIS thiab Microstation

Cov ntaub ntawv GML yog ib qho ntawm cov qauv zoo tshaj plaws los ntawm GIS developers thiab cov neeg siv, txij li thaum sib nrauj los ntawm kev ua ib qho kev txhawb thiab tsim los ntawm OGC, nws yog qhov tsis zoo rau kev hloov thiab pauv cov ntaub ntawv hauv web applications.

GML yog daim ntawv thov ntawm cov lus XML rau cov hom phiaj geospatial, nws cov lus aub npe sawv cev rau Geography Markup Language. Nrog rau qhov no nws yog qhov ua tau los xa hauv ntawv, ntawv vector thiab txawm siv cov duab los siv GMLJP2. Nws cov laj thawj yog raws li lub ntsiab txhais ntawm cov qauv ntawm node (dab tsi yog sawv cev muaj) thiab cov ntaub ntawv nws tus kheej, yog li GIS qhov kev pab cuam thaum nyeem GML cov ntaub ntawv ua ntej txhais nws cov ntaub ntawv ntawm cov yam ntxwv thiab tom qab ntawd qhia cov ntaub ntawv geographic muaj muaj.

Cov piv txwv ntawm cov duab dhau los yog sib npaug rau kev ua lag luam hauv kev ua lag luam, uas muaj cov cuab yeej hauv nws thawj zaug, thiab tib yam li ob qho khoom thaum nws raug muab kaw, nrog nws cov tswv cuab alphanumeric.

Yuav ua li cas nyeem cov ntawv GML uas siv QGIS.

Qhov no yog li yooj yim li tsuas yog dawb software ua tau:

• Txheej> ntxiv txheej> ntxiv vector txheej> tshawb

Qhov kev xaiv GML no raug xaiv, thiab qhov ntawd yog nws.

Los cawm ib txheej hauv QGIS ua GLM ntaub ntawv, cia li nias ntawm txheej, txuag tau thiab xaiv GML kev xaiv.

Ntawm no nws yog ib qhov tsim nyog los txhais ib co configurations, piv txwv li:

• Nws yog ib qho kev qhia, uas tej zaum yuav yog qhov uas twb muaj txheej txheej.
• Character encoding, Latin 1 yog qhov zoo tagnrho rau tsis muaj teeb meem nrog cov kab kos thiab cov tsiaj ntawv ñ hauv peb lub ntsiab lus Hispanic.
• Cov hom ntawv tseem ceeb heev, siv GML 3 yuav muaj ntau yam ruaj khov yog tias peb xav nyeem los ntawm lwm qhov kev pab cuam los yog yuav tsum siv differs ntawm Geoserver.
• Tsis tas li, nws yuav tsum tau tsim yog tias peb xav tau cov phiaj xwm suav nrog tib cov ntaub ntawv lossis nyias muaj nyias. Cov xwm txheej ntawm kev nyeem nws nrog Bentley Map, nws yog qhov yuav tsum tau muab qhov no cais, raws li piav qhia tom qab.

Yuav ua li cas nyeem ntawv GML nrog Microstation V8i

Qhov kev ua haujlwm no tsuas yog ua tiav nrog Microstation GIS applications, xws li Bentley Map, PowerView, Bentley Cadastre, lossis zoo sib xws.

Hauv kuv qhov teeb meem, yog tias kuv siv daim ntawv qhia Bentley, nws ua tiav li no:

• Cov Ntaub Ntawv> Ntshuam> GIS Cov Ntaub Ntawv Cov Ntaub Ntawv…

Raws li koj tau pom, ntawm no koj tuaj yeem hu rau chaw pheeb suab rau kev pabcuam raws li Web Feature Service WFS, Oracle Spatial, SQL Server.

SHP ntaub ntawv tsis txawv li lawv qhib natively.

Nyob rau hauv cov ntaub ntawv ntawm GML ntaub ntawv, qhov ntxiv GML cov ntaub ntawv ...

Hauv vaj huam sib luag uas tshwm, nws yuav tsim nyog xaiv yog daim ntawv schematic. Bentley schema cov ntaub ntawv yog lub npe hu ua XSD.

Thiab thaum twg qhov no ua tiav, txoj cai-nias rau ntawm Import1 lub sijhawm rov, thiab xaiv saib ua ntej los tso saib nws lossis Ntshuam coj mus rau hauv daim ntawv qhia.

Thaum nug cov khoom khawm "Analyze" khawm, cim ua ib lub iav tsom iav, thiab kov cov khoom, tabular cov ntaub ntawv yog tsa ob qho tib si ua ib lub thawv thiab xml code, raws li muaj nyob rau hauv cov duab nram qab no.

Kom export rau GML, tib txoj kev ua raws:

• Cov ntaub ntawv> Export> GIS Cov hom ntaub ntawv…

Hauv ob qho tib si, nrog QGIS thiab Bentley Daim Ntawv qhia, nws tseem ua tau kom yooj yim hloov GML raws li cov ntaub ntawv vector, nrog rau cov ntaub ntawv alphanumeric.
