I-software ye-GIS - echazwe ngamagama we-1000

Inyanga yakamuva kaMeyi, inguqulo ye-1.2 ishicilelwe lo mbhalo omfushane kodwa othakazelisayo onalolo gama kubonakala sengathi uhlekisa ukubunzima kwesofthiwe yokuphathwa kwedatha yendawo.

Kubhalwe nguStefan Steiniger noRobert Weibel base-University of Calgary eCalifornia nase-University of Zurich ngokulandelana. Ekugcineni banikeza izikweletu kweminye imithombo yesibili.

Ngemuva isingeniso esifushane, lapho izitayela eziyisisekelo zohlelo lokusebenza lwe-GIS zichazwa, idokhumenti iqukethe izihloko eziyinhloko ze-4:

I-GIS Software: Imiqondo

Lapha ukuhlukaniswa phakathi kwezindlela ezimbili eziyinhloko zokumelela idatha kwenziwa: I-Raster neVector.

Bese sebenzisa ngobuhlakani isimiso esidala esithi "Isithombe sidinga amazwi ayizinkulungwane" bese uveza isikrini se-OpenJump ukuveza izingxenye ezivame kakhulu zethuluzi le-GIS:

• Imenyu yomsebenzi
• Amathuluzi okuhamba
• Uhlaka lwendlala
• Amathuluzi wokuhlela
• Umbono wendawo wemephu
• Umbono we-tabular wezimfanelo

Imizila eyisisekelo ehambisana ne-GIS Software

Kulesi sigaba kukhona uhlu lwemisebenzi eziyisisekelo ye-9 umsebenzisi ayidinga ithuluzi:

1. Dala idatha
2. Hlela, uma kwenzeka idatha ishintshile
3. Isitolo, ngemuva kokwenza izinguquko
4. Buka ngeso lengqondo idatha evela eminye imithombo
5. Hlanganisa idatha evela eminye imithombo ekhona
6. Bheka ngokusekelwe ezimisweni
7. Hlaziya idatha bese udala imiphumela
8. Yenza kahle futhi ushintshe idatha ephuma ekuhlaziyweni
9. Shicilela okukhiphayo kuvela emabalazweni

Le nqubo ngaphambili ngangikhulume kuyo izigaba eziyisithupha Ngenkathi ngenza ibhukwana le-Manifold, kulokhu bayandisa lokho ukwakhiwa kwedatha okuhlukanisa labo abatholwa ngamanye amathuluzi nokuhlaziywa, ukuhlukanisa umbuzo olula, kusukela ekuhlaziyweni kwemiphumela nokuguqulwa kwidatha entsha.

1. Ukwakhiwa (Dala, ngeso lengqondo)
2. Ukuhlaziywa (Bheka, Hlola, Hlanganisa)
3. Ukushicilelwa (Shicilela)
4. Hlela (Hlela)
5. Ukuphatha (Ukugcina)
6. Shintsha (Hlanganisa)

I-GIS Software Categories

Kulesi sigaba se-7 izigaba ezahlukene ezahluke kuye ngokukhethekile, kufaka phakathi:

1. I-GIS yedeskithophu (ideskithophu)
   Umbukeli
   Umhleli
   Ukuhlaziya
2. Umphathi wedatha yendawo
3. I-server yemephu yewebhu
4. Iseva ye-GIS
5. I-Web GIS Client
   Okulula (njenge-Google Amamephu)
   Kunzima (njenge-Google Earth)
6. I-GIS yeselula (i-Mobile GIS)
7. Ama-Libraries kanye nezandiso ze-GIS

Ngaphandle kwegrafu, itafula elifanisayo lifakwe lapho imisebenzi ye-9 yangaphambilini iwela khona ngezigaba ezikhethekile zesofthiwe.

Abakhiqizi be-GIS Software kanye neMisebenzi 

Kulokhu, okushiwo yizinkambiso ezinkulu ekukhiqizeni isofthiwe, ezokuhweba nokukhululekile.

Ukuhweba kubhekisela ku-AutoDesk, Bentley, ESRI, GE (Small World), noPitney Bowes (Mapinfo)

Futhi phakathi kwesofthiwe yamahhala kukhulunywa nge-MapServer, GeoServer, PostGIS, Quantum GIS, kanye ne-gvSIG.
