Iikhosi zeMephu zeGIS: ezilungileyo zikhona.

ImephuGIS, ngaphandle kokusinika umdla blog, Lugxile nohlobo zoshishino on an online ngoqeqesho ngezihloko kwimeko geospatial.

Ngowama-2013 kuphela, bangaphezulu kwama-225 abafundi abathatha izifundo zabo, inani elibonakala linokuqwalaseleka kum, xa kuthathelwa ingqalelo ukuba iinzame zikhona koosomashishini ababini abaqale oku ngaphezulu konyaka odlulileyo. Ke sisebenzisa ithuba lokuqala kuka-2014 ukukhuthaza inyathelo lakho.

  • Sebenza ngeendlela kunye neenkonzo zangaphandle.
  • Hlela idatha yendawo
  • Sebenza kunye nokulungelelanisa iinkqubo kunye nemifanekiso georeference yeraster.
  • Yenza isymboli kunye neelebheli.
  • Yenza iziqulatho zemephu.
  • Yenza geodatabases kunye yethopholoji efanayo.
  • Yenza uhlalutyo lomhlaba.
  • Sebenza nge SEXTANTE.
  • Shicilela imephu kwi-intanethi

Inkqubo ye-Intanethi yeziseko zedatha: i-PostGIS. 

Qala ukulawula i-PostGIS yolwazi oluvulekile lwendawo yolwazi lwendawo.

Kule khosi iimfuno ziyahlangatyezwa ngolu hlobo: Ungangenisa njani iifayile zesiseko sedatha? Ungasikhawulezisa njani isantya sokuphendula xa usenza imibuzo? ukuba uhlalutyo lomhlaba lwenziwa njani? Kutheni kukho uhlobo lwejometri nohlobo lwejografi? Uyibona njani ukuba yeyiphi idatha ekwi-PostGIS?

 Ukongeza, uya kufunda methodologically, inyathelo ngenyathelo;

  • Uyifaka njani i-PostgreSQL + PostGIS
  • Uyenza njani i-database kwaye uyinike indawo yendawo
  • Indlela ukulayisha iinkcukacha ezingomhlaba
  • Uyijonga njani kwaye uyifumana njani idatha egcinwe kwi-PostGIS
  • Zeziphi iintlobo zejometri ezikhoyo
  • Ndilwenza njani uhlahlelo lwendawo kunye nemisebenzi ekhoyo yendawo
  • Uyikhawulezisa njani imibuzo
  • Ungasebenza njani ngedatha ye-raster
  • Njani umsebenzi kunye data OpenStreetMap
