Iiplatifti ze-GIS zamahhala, kutheni zingabonakali?

Ndiyishiya indawo evulekile ukucinga; indawo yokufunda ibhulogi imfutshane, ngoko ndiyayilumkisa, kuya kufuneka sibe yinto elula.

Xa sithetha nge «izixhobo ze-GIS zamahhala«, Amaqela amabini amajoni avela: uninzi olukhulu olubuza umbuzo
... kwaye yintoni ezo?
... kwaye kukho abasebenzisi babo?

Nangona iincinci zitholakala ngaphesheya kwesiteji, zinemibuzo efana nale:
... Ndenza okungakumbi ngaphandle kokuchitha imali

Nazi ezinye zezizathu zokuba iipulatifomu zamahhala zingekho kwifesenti yabasebenzisi abaninzi be-GIS.

1. Ikhefu lokufunda
ingca Kwimeko GRASS, ukunika umzekelo, esi sixhobo sisebenza kunye neLuxux kunye neWindows, enayo API kwiC well ziweyo, onayo abaqeqeshiweyo ngokugqibeleleyo, emva kokuvavanya siqinisekisa ukuba yenza imisebenzi ye-ARCGis, kunye nezandiso zayo ezininzi ezixabisa amawaka eedola.

... kodwa ngubani onika iklasi ye-GRASS kwilizwe laseLatin America?

Andithethi ngoqeqesho lwabaphuhlisi, bafunda bodwa, ngaphandle kwabaqhubi abaqhelekileyo bohlalutyo lomhlaba, ukusetjenziswa kwemifanekiso, ukuguqulwa kwedatha ye-raster kwi-vector ... ezo zinto zenziwa li-GRASS kakuhle. Ngokuqinisekileyo ukuhambisa uqeqesho lwe-GRASS kufuneka kube lula kakhulu, malunga neeyure ze-24, kodwa isangqa esikhohlakeleyo sokuba kukho imfuno encinci kwezi zifundo kuthetha ukuba iinkampani ezinikezelwe kuqeqesho azicwangcisi iinkomfa ngalo mbandela. Masingathethi ngezinye iinkqubo zasimahla okanye zasimahla ezifana ne-gvSIG, intlakohlaza, ISaga okanye iJump engaziwa.

Ngoko ukuba i-curve yokufunda ixhaphake kakhulu yenza abasebenzisi baxabise ... ngendlela efanayo neLuxux inkululeko, kodwa inkonzo yaseRedHat exhaswe kakuhle ibiza imali eninzi.

2 Kulula ukukrhaqha kunokufunda
Kucacile ukuba i-ESRI kunye ne-AutoDesk ziyathandwa kuba ubuqhetseba bubolekise isandla ... okanye ihhuku. Nangona ziqinile kakhulu, zahlukahlukene kwaye ngokungathandabuzekiyo zixhaswa kakhulu ziinkampani ezaziwayo, inkampani encinci okanye encinci enikezelwe kwindawo ye-cartographic kufuneka ityale imali eyi- $ 48,000 yeedola kwiimveliso ze-ESri ukuqala nje isebe lophuhliso labasebenzisi be5 ( I-ArcGIS, i-ARCsde, uMhleli we-ARC, i-IMC ye-ARC ... ngaphandle kwe-GIS Server). Ke amaqonga omthombo ovulekileyo ngumtsalane olungileyo kwiinkampani ezinikezelwe ekuphuhliseni, kodwa abaqhubi abaqhelekileyo abaza kusebenzisa i-desktop kuphela ... baya kubeka isiziba esweni, kwaye bachithe i- $ 1,500 online :).

3 Kungcono ukuhamba kunye nezona ziwayo kunokuba zilungele.
Sisabona esi siko xa kufikelele ekusebenziseni imali, umsebenzisi uyazi ukuba iMac ibhetele kunePC, ukuba iLuxu ingcono kune-Windows, ukuba ezinye izixhobo ze-CAD zingcono kune-AutoCAD; ukwenzela ukuba ezi ziqonga ezincintisana noDavid noGoliyati zihlala ezandleni za "khetha abasebenzisi" abahlawula amanani afanayo.

Nangona kumncintiswano phakathi "ngokukhululekile" kunye "neendleko", udonga luba lukhulu, ngaphezu kweyodwa ndahamba kuthathwa ngabantu abathandekayo, yokusebenzisa iManifold ... nangona isimahla. Ke, sisebenzisa izixhobo ezibiza i- $ 4,000 nje ukusigcina si-Geek, nangona uninzi lwabasebenzisi bengasebenzisi ilayisensi, kodwa iinkampani.

... ukuqukumbela, sibona ukuba kubububi obuyimfuneko ukuba kukho iinkampani ezinkulu, zibiza amawaka eedola ilayisensi ukuze ibango lobuchwepheshe lihlale lihleli. Kwaye iya kuqhubeka ingobunye ububi obuyimfuneko, ukuba iqela liqhubeke nokulwa lisuka kwicala lomthombo ovulekileyo, nangona uninzi luya kuzijonga njengeNerds.

Iimpendulo ze-5 kwi "platforms ze-GIS zamahhala, kutheni zingabonakali?"

  1. Ukuphendula umbuzo owawuthunyelwe ngeposi:

    I-GIS ehamba kwi-Apple:
    -QGIS. Le yona yakhiwe kwi-C ++
    -GvSIG. Yakhelwe kwiJava, into enomda kwi-Mac ngenxa yokuba iqhuba njengohlobo oluphathwayo. Ukusetyenziswa kwayo kakhulu kwiLinux nakwiWindows
    -Vula iTsiba. KwiJava, kodwa ngaphambi kwale gvSIG iyabaluleka.

    Ezinye iinketho zisebenza kwiiparalells, ezibangela ukuba izicelo zeWindows ziqhube kwi-Mac.

    Zam iingcebiso:

    Hlanganisa i-gvSIG kunye ne-SEXTANTE, kulabo abangesabi iJava
    Hlanganisa iQGIS kunye ne-GRASS, kwabo bakhetha iC ++

    Ukuphuhlisa iwebhu

    GeoServer yeJava
    MapServer okanye iMaphuGuide ngaphezu kweC ++

  2. Kulungile Jc. Esi sithuba sivela kwi-2007, okwangoku sibone ukuvela kwemodeli evulekileyo, kwaye sonke silindele ukuba iziphumo zayo zokugqibela zizinzile.

    ukubingelela

  3. Ndiyicinga ukuba lixesha le-software yomthombo ovulekile, ukuba yintoni efunekayo kukuba kukho uluntu oluphuhlisa.
    Kwimeko ye-gvSIG, olu luntu lusebenza kakhulu kwaye lwandisa ngesantya esikhulu, kunye nekhosi zoqeqesho kwiindawo ezininzi kunye nenkxaso yobugcisa. Kuyinyaniso ukuba izixa ezikhulu inkqubo yolwazi uyehla kwaye mhlawumbi ArcGIS okanye nayiphi na enye software kwegunya ikulungele ngcono ukusebenza ngcono. Kodwa ke umbuzo kukuba balungiselelwe njani data, okt ukuphunyezwa kwe-GIS ka-zolawulo oluntu kunye namashishini olukhulayo, kwaye ntsingiselo kukuba onke umvelisi lolwazi umzobo up inkcazelo yayo kwiinkqubo kwaye walibeka eziqhelekileyo kwizibonelelo zedatha, ngokuthotyelwa kwemigangatho (i-WMS, i-WFS, njl. njl.) apho endaweni yokugxininisa idatha, zihlukeneyo kumaseva abelana ngolwazi, kunye naloo mqulu womsebenzi, isofthiwe yomthombo ovulekile, njenge-gvSIG, ebhaliwe kwiJava, ukuba iyincedo.
    Ndiyathemba kwaye ndibetha kwi-software yomthombo ovulekileyo, kuba kwezinye iindidi zemihlaba, ithatha umhlaba kwiprosoftware yangasese, (isakhelo esinjengeDrupal, i-CMS WordPress, elgg, njl.
    Ixesha elizayo lixhomekeke ekuxhumeni nasekuhlanganisweni kwazo zonke izixhobo zesistim evulekile, ekugqibeleni uRichard Stallman uya kulungile.
