Thaum peb tab tom xaus lub neej QGIS nyob rau hauv 2.x cov ntawv, tos seb dab tsi yuav QGIS 3.0, nplooj ntawv no qhia peb tias QGIS 2.18.11 'Las Palmas' suav nrog, uas tau ua tiav hauv lub hlis ntawm Lub Xya Hli xyoo no.
QGIS tam sim no muaj ib qho kev nthuav rally li tshiab sponsors, formal tuam txhab uas muag uas muaj kev txhawb nqa thiab Nkij los txuam rau mus rau lwm cov kev daws teeb meem, xws li cov ntaub ntawv ntawm tsis kawg thiab tsis ntseeg ob lub qhov muag rov qab qhua mus rau ib tug hwm li cov neeg siv.
Daim ntawv tshaj tawm qhia peb tias tam sim no version muab cov kev txhim kho ntxiv rau yav dhau los. Tag nrho cov kev taw qhia no rau txoj kev loj hlob ntawm QGIS 3.0 uas yuav dhau los ua lub cim ntxiv ntawm cov tshiab thiab tias, txawm qhov tshaj tawm, tsuas yog ob peb tug tau pom nws lub ntsej muag. Peb tau tawm tswv yim rau nws ua ntej no.
Rov qab mus rau qhov kev kawm. Cov kev txhim kho nyob rau hauv no version tau cais ua pawg. Qhov kawg ntawm ib qho, rau lub hom phiaj ntawm qhov tseeb hauv txoj kev loj hlob, peb yuav subdivide nws hauv ob. Yog li, peb muaj 27 hloov nyob rau hauv 13 pawg:
- General
- symbology
- labeling
- Rendering
- Kev tswj cov ntaub ntawv
- Cov Ntaub Ntawv thiab Cov Ntaus
- Tsim cov Cuab Yeej
- Ua
- Cov Neeg Muab Kev Pab
- QGIS neeg rau zaub mov
- plugins
- Programmability
- Tshiab nta
- Cov chav kawm
- Piav Qhia Zis
Nyob rau hauv txhua ntawm lawv ib los yog ob peb yam ntxwv yog sau. Cov lus nram qab no piav txog kev tsim kho

Lub xaib qhia txhua yam ntawm kev txhim kho, uas tuaj yeem kawm ib leeg los ntawm ib qho. Ua piv txwv, Kuv xav xa mus rau cov yam ntxwv uas feem coob ntes kuv: kev txhawb nqa rau cov kev pab cuam WMTS thiab XYZ kev pabcuam mosaicCov. Cov no poob rau hauv ob pawg: Rendering thiab Cov Ntaub Ntawv Qhia. Cia peb saib:
Rendering: Feature.- Saib ua ntej ntawm cov vuas raster (cov txheej ntawm WMTS thiab XYZ)
Lub novelty yog tias, tsis zoo li yav dhau los versions, tam sim no nws tsis yog yuav tsum tau tos rau kom tiav download ntawm vuas mus saib daim ntawv qhia. Qhov no yog vim lawv pom nyob rau hauv cov ntaub qhwv cov ntaub ntawv raws li lawv tau downloaded, thiab, nyob ntawm lawv qhov kev daws teeb meem, lawv tuaj yeem siv los ua qhov kev tshawb xyuas yav dhau los hauv cov cheeb tsam uas cov mosaics nrog txoj kev daws teeb meem tseem tsis tau muab luam tawm.
Rendering: Characteristic.- Tshem tawm ntawm rasters rendering (WMS, WMTS, WCS thiab XYZ txheej)
Tam sim no cov rendering ntawm lub rasterized txheej yuav raug muab tso tseg txhua lub sij hawm thiaj li yuav tau zoom daim ntawv qhia tsis zoo li yav dhau los vim hais tias tus neeg siv interface tau 'khov' thaum lub download ntawm cov vuas. No cov tshiab feature pab txoj haujlwm ntawm kev dai raster txheej ntawm thaj chaw nruab nrab.
Cov neeg zov me nyuam cov ntaub ntawv: Tus Cwj Pwm: - Txhawb nqa XYZ mosaic cov khaubncaws sab nraud povtseg
Tam sim no tsis tsim nyog siv cov 'txawv teb chaws' plugins xws li QuickMapServices lossis OpenLayers vim tias tam sim no cov rasterized mosaics hauv XYZ hom tau txais kev txhawb ib txwm nyob hauv WMS cov chaw muab ntaub ntawv uas nws muaj peev xwm los saib basemaps los ntawm ib tus qauv twg. Piv txwv, yog tias peb xav ntxiv qhov qhib StreetMap basemap siv qhov URL no: http://c.tile.openstreetmap.org/{z} / {x} / {y} .png. qhov twg {x}, {y}, {z} yuav hloov los ntawm cov xov tooj tam sim no ntawm daim pheem siv. Koj tseem tuaj yeem siv bing's 'quadkey' los hloov {q} nrog {x}, {y} lossis {z}.
Muaj qee qhov kev txhim kho uas yuav muab ntxiv rau cov uas tau hais lawm. Ua ntej, tseem yuav tau xaiv ntawm peb cov ntawv siv qhov tseeb ntawm sab qaum teb los yog sib nqus. No feature yog nyob rau hauv qeb ntawm Cov Ntawv Tsim. Peb kuj yog ntaus los ntawm ob daim ntawv teev cov haujlwm tshiab ntxiv, nrog rau cov kev paub zoo dua hauv kev ua haujlwm.
Hauv ntej, daim ntawv tshaj tawm uas tsim nyog rau peb qhov kev nyeem ntawv kom paub ntau tshaj qhov kev txhim kho tshiab los ntawm QGIS.
Qhov no tsuas yog ib qho qauv ntawm kev txhim kho, tab sis kuv pom zoo kom mus tshaj tawm cov ntawv tshaj tawm no.
QGIS yuav tsis yog dab tsi nws yog tsis muaj kev pab txhawb nqa, thoob ntiaj teb, ntawm pawg neeg coob coob (cov neeg tsim khoom, cov ntawv sau cia, cov ntawv sim, cov neeg tuaj yeem, cov neeg txhawb nqa, thiab lwm yam) uas yog vim li cas zej zog ua tsaug thiab qhia peb txog txoj kev koom nrog rau cov pab pawg thiab txhawb lawv raws li koj pom tias tsim nyog.
