Amathuluzi e-vector e-QGIS awekho ekhaya: ukufaka noma iphrofayela?

Vula iphrojekthi efanayo ye-QGIS ekhaya, uthole ukuthi amathuluzi e-vector awekho, futhi ithuneli ibonakala inecala. Ngokuvamile ayilona, nakuba kuyi-VPN eyabeka izimo ezimbili ndawonye. Ifayela lephrojekthi liphethe izendlalelo, izitayela nezilungiselelo zephrojekthi; aliphethe uhlu lwama-algorithms. Amathuluzi angawokufaka okwenza umsebenzi kanye nophrofayela okulayishe lokho kufaka.

Nquma ukuthi yikuphi ukufaka okwenza umsebenzi

Idesktop yokude evunyelwe ekhombisa i-QGIS yasehhovisi ibonakala ifana nokufaka kwendawo kuze kube yilapho uhlola okwenzekayo ngempela. Kulolo hlelo ama-algorithms avela emshinini wokude nasemphrofayeleni wawo, kanti ikhompyutha yakho yasekhaya idweba amaphikseli kuphela. Hlola inguqulo nephrofayela esebenzayo ngaphakathi kwesesheni yokude, hhayi leyo ekudesktopini yakho.

Lapho i-QGIS isebenza endaweni, ukufaka kwasekhaya kunikeza konke. Ngaleso sikhathi i-VPN inomsebenzi owodwa: ukufinyelela idatha.

Bhala inombolo yangempela yokwakha, igama lephrofayela esebenzayo kanye nohlu lwama-plugin emshinini owenza umsebenzi. Qhathanisa nalokho okuhlanganiswa okusekelwa umphathi wakho we-GIS, hhayi ngesithombe sesikrini esidala. Ukwakha kabusha ikhompyutha ephathekayo ene-Windows 7 ukuze ihambisane nokuhlelwa kwemenyu yomlando akuxazululi lutho futhi kwakha indawo yesibili engasekelwe. Uma imishini emibili ihluke ngempela, isinqumo siwukuvumelana ngokwakha okukodwa okusekelwe, hhayi indlela yokugwema.

Imenyu ye-Vector ibonisa i-plugin ye-Processing

I-QGIS igcwalisa imenyu ye-Vector ngezinqamuleli eziya kuma-algorithms avela kubaphakeli abayisisekelo, ngakho imenyu encane engenalutho ngokuvamile isho ukuthi i-plugin ye-Processing ayivuliwe kulokho kufaka. Vula umphathi wama-plugin futhi uqinisekise ukuthi i-plugin eyisisekelo ivuliwe, bese uqalisa kabusha i-QGIS futhi ubheke futhi. Lesi silungiselelo sohlelo, futhi akukho ukulungisa iphutha kwethuneli okuzokushintsha.

Ungafunda isimo esifanayo kusuka kutheminali, okushesha kunokuchofoza kumamenyu kuxhumano olunensayo:

$ qgis_process plugins
$ qgis_process list | grep -i "native:buffer"
native:buffer  Buffer
$ qgis_process help native:buffer

Lapho i-plugin iphendula, qhathanisa umphakeli womsebenzi owudinga ngempela. I-algorithm yendawo, umphakeli ovela ngaphandle kanye nemodeli eyakhiwe ekhaya kungaba nezimo zokuqala ezihlukene, futhi amamenyu amabili abonakala efana kungenzeka angabi nayo into efanayo. Bhala igama lomphakeli kusuka ebhokisini lamathuluzi futhi ulihlole ngegama, hhayi ngesikhundla ohlwini.

Amaphrofayela achaza amathuluzi angekho ngaphandle kokufaka kabusha

Iphrofayela yomsebenzisi we-QGIS igcina izintandokazi, ama-plugin avuliwe kanye nokulungiselelwa kwe-Processing, futhi yikho kanye lokhu okwenza umshini owodwa uzizwe uhlukile komunye. Umphathi wamaphrofayela uvula isimo esihlukile, esihlanzekile, futhi leso simo ngokufanelekile sizontula amathuluzi anayo iphrofayela yakho yasehhovisi.

Sebenzisa iphrofayela ehlanzekile njengendawo yokuqhathanisa, hhayi njengokushintsha. Uma ithuluzi livela lapho, umehluko usema-plugin noma ezilungiselelweni ze-Processing zephrofayela yakho yamanje; uma lingaveli, igebe lisekufakweni futhi ubheka isendlalelo esingalungile ngokuphelele.

Ukukopisha yonke ifolda yephrofayela yozakwenu kuyindlela emfushane engalungile. Idonsa izilungiselelo ezingahlobene, izincazelo zokuxhumana kwesizindalwazi kanye nokulungiselelwa kokuqinisekisa okungakaze kuhloselwe i-akhawunti yakho. Cela umphakeli, imodeli noma isilungiselelo esithile esikhundleni salokho, bese usifaka ngesixhumi esibonakalayo esisekelwe.

Lowo mehluko futhi uvikela ukulungiselelwa kwehhovisi ekuhloleni kwakho, futhi lokho kubaluleke kakhulu kunokonga imizuzu eyishumi.

Ukwehluleka komthombo wedatha kubonakala kuhlukile kune-algorithm engekho

Lapho i-algorithm ikhona, ukwehluleka okulandelayo kuzoba mayelana nokufinyelela isendlalelo. Ukuxhumana kwe-PostGIS, indawo yokuphetha ye-WMS noma ye-WFS kanye nefayela kudrayivu ehlanganisiwe kwehluleka ngayinye ngendlela yayo, futhi incwadi yedrayivu esebenza ehhovisi ngokuvamile ayisho lutho ekhaya. Sebenzisa igama lomsingathi wangasese elihlosiwe kanye nobufakazi besevisi uqobo kanye nezidingo zayo ze-TLS.

Hlola ngezinyathelo ezimbili futhi umyalezo wephutha uzokutshela ukuthi ufone ubani. Qala ngokwenza umsebenzi kusampula yendawo encane, engazweli ekhaya yohlobo lwejiyometri olulungile; uma iphumelela, i-algorithm nephrofayela zilungile, ngakho noma yikuphi ukwehluleka esendlalelweni esiyimfihlo kungokwenethiwekhi noma kwesevisi. Uma nesampula ihluleka, yeka ukusola i-VPN bese ubuyela ekuhloleni kwe-plugin nephrofayela.

Qeda ngokugcina umphumela endaweni evunyelwe nangokugcina irekhodi elifushane eceleni kwephrojekthi: ukwakha kwe-QGIS, iphrofayela, umphakeli we-algorithm kanye nezindlela zedatha. Khonokho ukuthuthukiswa okulandelayo noma ikhompyutha ephathekayo entsha kuzoqala ngamaqiniso esikhundleni somunye umjikelezo wemivubukulo yemenyu.
