Dawb GIS platforms, yog vim li cas lawv tsis nrov?

Kuv tawm hauv qhov chaw qhib mus rau yav tom ntej; qhov chaw rau kev nyeem blogs yog luv luv, yog li kuv ceeb toom, peb yuav tsum tau simplistic me ntsis.

Thaum peb tham txog "dawb GIS cov cuab yeej", ob pab tub rog tshwm sim: feem coob uas nug cov lus nug
... thiab zoo li cas?
... thiab muaj cov neeg siv ntawm lawv?

Thaum ib tug neeg tsawg muaj nyob rau sab nraud ntawm theem, nrog cov lus teb xws li:
... Kuv ua ntau yam tsis siv nyiaj

Nov yog qee cov laj thawj yog vim li cas dawb platforms tsis nyob rau hauv lub zam ntawm feem coob ntawm cov neeg siv GIS.

1. Txoj kev kawm nkhaus.
Nyob rau hauv cov ntaub ntawv ntawm NYOM, muab ib qho piv txwv, qhov cuab tam ua haujlwm nrog Linux thiab Windows, uas muaj ib tug API hauv c zoo sau tseguas muaj tutorials ua tiav, tom qab kuaj nws peb tau txheeb xyuas tias nws ua haujlwm ntawm ARCGis, thiab ob peb qhov txuas ntxiv uas muaj nqis ntau txhiab daus las.

... tab sis leej twg muab koj lub chav GRASS hauv ib lub tebchaws Latin America?

Kuv tsis hais txog kev cob qhia rau cov neeg tsim khoom, lawv kawm los ntawm lawv tus kheej, tsis muaj cov neeg ua haujlwm sib koom thiab tam sim no ntawm kev tsom xam, kev ua duab, hloov pauv cov ntaub ntawv raster rau vector ... cov khoom uas GRASS ua tau zoo heev. Muaj tseeb muab GRASS kev cob qhia yuav tsum yooj yim heev, NW nyuam qhuav 24 teev, tab sis lub voj voog uas muaj kev thov tsawg heev rau cov kev kawm no txhais tau hais tias cov tuam txhab mob siab rau kev cob qhia tsis teem sijhawm cov rooj sib tham txog cov ncauj lus no. Tsis txhob hais txog lwm yam kev pab dawb lossis dawb xws li gvSIG, Caij nplooj ntoos hlav, Dabneeg lossis Dhia uas tsis tshua paub.

Yog li qhov tseeb tias txoj kev kawm nkhaus yog qhov ntau heev ua rau cov neeg siv nyiaj kim ... tib txoj kev uas Linux yog dawb xwb, tiam sis RedHat qhov kev pab cuam zoo txaus cov nqi ntau heev.

2. Nws yog yooj yim dua hack dua kawm
Nws yog tseeb hais tias ESRI thiab AutoDesk yog nrov vim piracy tau muab rau lawv ib txhais tes ... los yog ib tug nuv. Txawm hais tias lawv muaj zog heev, ntau yam cuab yeej thiab undoubtedly heev endorsed los ntawm ib tug renowned tuam txhab uas muag, ib tug micro los yog me me kev lag luam mob siab rau lub cartographic cheeb tsam yuav tsum nqis peev tsawg kawg yog $ 48,000 las nyob rau hauv ESRI cov khoom xwb los pib ib tug kev loj hlob department ntawm 5 cov neeg siv (ArcGIS , ARCsde. , ARC Editor, ARC IMS… tsis muaj GIS Server). Yog li qhib qhov chaw platform yog qhov zoo rau cov neeg tsim khoom, tab sis cov neeg ua haujlwm zoo li desktop nkaus xwb yuav hnav lub qhov muag thiab siv $ 1,500 online :).

3. Nws yog qhov zoo dua mus nrog cov sawv daws nyiam dua nrog qhov zoo tshaj plaws.
Peb pom qhov kev cai no txawm tias thaum siv nyiaj, tus neeg siv paub tias Mac zoo dua li PC, tias Linux zoo dua Windows, tias qee cov cuab yeej CAD zoo dua AutoCAD; yog li cov platforms uas sib tw zoo li David thiab Goliath tseem nyob hauv txhais tes ntawm "xaiv cov neeg siv" uas them tus nqi zoo sib xws.

Thaum nyob rau hauv kev sib tw ntawm "yuav luag dawb" thiab "kim", lub phab ntsa ua gigantic, ntau tshaj ib zaug kuv yog npaum li cas rau gentle, rau kev siv Manifold ... txawm hais tias nws tsis pub dawb. Yog li, peb siv cov cuab yeej uas raug nqi $ 4,000 tsuas yog nyob rau Geek, txawm hais tias feem ntau cov neeg siv tsis tau ntawv tso cai software, tab sis cov tuam txhab.

… Hauv kev xaus, peb pom tias nws yog qhov tsim nyog ua phem uas cov tuam txhab loj muaj nyob, them nyiaj ntau txhiab daus las rau daim ntawv tso cai kom qhov kev thov rau cov thev naus laus zis no ruaj khov. Thiab nws tseem yuav yog lwm qhov kev phem tsim nyog, uas ib pab pawg tseem tawm tsam los ntawm qhib qhov chaw, txawm hais tias feem coob yuav xav txog lawv Nerds.
