GIS mapuratifomu akasununguka, nei asingazivikanwi?

Ndinosiya nzvimbo yakazaruka kuti ndifungisise; nzvimbo yekuverenga mabhuku yakapfupi, saka ndinonyevera, tichafanirwa kunge tisinganyatsonzwisisiki.

Kana tichitaura nezve "zvisizvo zveGIS zvishandiso", mapoka maviri evarwi anooneka: ruzhinji runobvunza mubvunzo
... uye zvii izvo?
... uye kune vashandisi vavo?

Kunyange zvazvo vashomanana varipo kune rumwe rutivi rwechitambo, vane mhinduro dzakadai se:
… Ini ndinoita zvakawanda ndisina kushandisa mari

Heano zvimwe zvikonzero nei pasina mahwendefa asina kufanana nemafungiro evanhu vakawanda veGIS.

1. Ikoji yekudzidza.
Munyaya ye GRASS, kupa muenzaniso, shanduro iyi inoshanda ne Linux neWindows, iyo ine API in C well zvakanyorwa, iro rine tutorials zvakakwana, mushure mekuyedza isu takaongorora kuti inoita mashandiro eARCGis, uye akati wandei ekuwedzera ayo anokosha zviuru zvemadhora.

... asi ndiani anokupai kosi yeGRASS mune imwe nyika yeLatin America?

Ini handisi kutaura nezve kudzidziswa kwevanogadzira, ivo vanodzidza vega, vasina zvakajairika uye zvazvino vashandisi vekuongorora nzvimbo, kugadzirisa mifananidzo, kutendeuka kwedhata raster kune vector ... izvo zvinhu izvo GRASS zvinoita chaizvo. Chokwadi kupa kudzidziswa kweGASS kunofanirwa kuve kuri nyore kwazvo, zvisingaite maawa makumi maviri nemana, asi denderedzwa rinotyisa rekuti pane kudikanwa kushoma kwedzidzo idzi zvinoreva kuti makambani akatsaurirwa kudzidziswa haarongedze misangano nezvenyaya iyi. Ngatisataurei nezve mamwe emahara kana emahara zvirongwa senge gvSIG, chitubu, Saga kana Jump izvo zvisingazivikanwi.

Saka chokwadi chekuti kudzidza curve kwakawanda kwazvo kunoita kuti vashandisi vadhura ... nenzira imwechete iyo Linux yemahara, asi inotsigirwa neRedHat inotsigirwa inoda mari yakawanda.

2 Zviri nyore kukanganisa kupfuura kudzidza
Zviripachena kuti ESRI uye AutoDesk dzinozivikanwa nekuti piracy yakavapa ruoko ... kana hoko. Kunyangwe idzo dzakasimba kwazvo, maturusi akasiyana uye pasina mubvunzo anotsigirwa nekambani ine mukurumbira, bhizinesi diki kana diki rakatsaurirwa kunzvimbo yemifananidzo rinofanira kuisa mari inosvika madhora makumi mana nemazana masere emadhora muzvigadzirwa zveESRI kungotanga dhipatimendi rekuvandudza revashandisi vashanu (ArcGIS , ARCsde, ARC Mupepeti, ARC IMS… isina GIS Server). Saka rakavhurika sosi mapuratifomu idhizaini yakanaka kune vanogadzira, asi zvakajairika desktop-chete vanoshanda vanopfeka chigamba cheziso uye kushandisa $ 48,000 pamhepo :).

3 Zviri nani kuenda nevanonyanya kuzivikanwa kupfuura kune zvakanakisisa.
Tinoona tsika iyi kunyange pakushandisa mari, mushandisi anoziva kuti Mac iri nani pane PC, kuti Linux iri nani pane Windows, kuti mamwe maturusi eCAD ari nani pane AutoCAD; saka mapuratifomu aya anokwikwidza saDavid naGoriyati anoramba ari mumaoko e "sarudza vashandisi" vanobhadhara mitengo yakafanana.

Ndichiri mumakwikwi pakati pe "anenge akasununguka" uye "anodhura", rusvingo rwunova rwakakura, kanopfuura kamwe chete ini yakatorwa nevahedheni, yekushandisa Manifold ... kunyangwe isiri yemahara. Nekudaro, isu tinoshandisa maturusi anodhura $ 4,000 kungogara Geek, kunyangwe vazhinji vashandisi vasina rezinesi software, asi makambani.

… Mukupedzisa, tinoona kuti chakaipa chakakosha kuti makambani makuru avepo, achibhadharisa zviuru zvemadhora rezinesi kuitira kuti kudiwa kwehunyanzvi uhu kugadzikane. Uye icharamba ichive humwe huipi hunodiwa, kuti boka rinoramba richirwira kubva parutivi rweyakavhurwa sosi, kunyange hazvo ruzhinji ruchazvitora seNerds.
