Raws li Mapserver ua hauj lwm

Lub sijhawm dhau los peb tham txog qee cov txheej xwm MapServer thiab cov hauv paus ntawm kev teeb tsa. Tam sim no cia peb pom qee yam ntawm nws txoj haujlwm hauv kev tawm dag zog nrog daim duab qhia ntawm Chiapas cov phooj ywg.

  Qhov twg nws yog mounted

Thaum Apache muab ntsia, lub vas sab ntawv luam tawm rau MapServer yog OSGeo4W nplaub tshev ncaj qha saum C: /

Sab hauv, muaj cov ntawv sib txawv sib txawv nrog cov ntawv thov nyob ntawm qhov tau teeb tsa, tab sis daim nplaub tshev rau kev tshaj tawm yuav tsum mus sab hauv apache. Hauv qhov no daim nplaub tshev hu ua gis.

• Tom qab ntawd, sab hauv, cov ntaub ntawv ceev tseg muaj txheej, orthophoto, thiab lwm yam.
• Hauv cov nplaub tshev thiab lwm yam, muaj qhov tseeb hom fonts siv rau cov ntawv, nrog .ttf txuas ntxiv. Tsis tas li ntawm no yog ib daim ntawv txt uas txhawb nqa lawv thiab lwm qhov uas txhais cov cim.
• Thiab thaum kawg nyob rau hauv daim ntawv httdocs mus rau cov nplooj ntawv web uas nqa cov kev pabcuam.
• 

lub vas sab

Hauv qhov ua piv txwv, Kuv yuav siv tus plua plav uas pom zaum tag los. Nws yeej muaj qhov Performance index ua cov ntawv xa mus rau ib qho nrog phtml txuas ntxiv, thiab qhov no nyeg nce cov haujlwm ua rau sab saum toj ntawm php thiab cov duab qhia chaw. Cov ntawv tais ceev tseg muaj cov duab txuas ntawm nplooj.

Yog tias peb saib nws, phtml tsuas yog lub plhaub ua los ntawm cov ntxhuav, thiab hu rau mapscript / php functions. Koj yuav tsum tau sawv siv:

http://localhost/gis/gispalenque.phtml

Cov txiaj ntsig tau qhia nyob rau hauv qab no:

• rau qhov chaw ua haujlwm GMapDrawMap (),
• ntawm txoj cai hu rau GMapDrawKeyMap keymap (),
• cov txheej txheem teev hauv qab no GMapDrawScaleBar (),
• thiab nyob rau hauv cov ntaub ntawv ntawm tso tawm functions, ib tug mob hais txog lub npe yog (! IsHtmlMode ()) ncha "  nrog rau kev txiav txim siab: ZOOM_IN, ZOOM_OUT, RECENTER, QUERY_POINT.

Twb khiav lawm, cov lus zoo li no:

Cov ntaub ntawv .map

Kev sib koom ua ke ntawm cov ntawv xov xwm hauv Dataerver yog nyob rau hauv dab Apache qhov teeb meem, uas xa tawm php los ntawm mapscript thiab cov ntawd tuaj tawm dhau lub plhaub ntawd. Tab sis feem ntau ntawm kev tshawb fawb nyob hauv .map cov ntaub ntawv, kom tsis txhob ntxhov siab nrog cov uas tsim los ntawm Mapinfo, Manifold, lossis Mobile Mapper Chaw ua haujlwm nrog tib qho kev nthuav dav.

Cov .map yog cov ntawv luam cov ntaub ntawv, uas muaj cov kab ntawv hauv cov ntawv sau. Cov no tuaj yeem tsim nrog desktop programs zoo li Quantum GIS, yog tias koj pom muaj ib qho rau daim ntawv qhia tseem ceeb, ib qho yog rau Keymap thiab ob qho rau OGC wms thiab wfs cov kev pabcuam. Cia saib yuav ua li cas mapscript ua haujlwm:

Los xaus

Li no, ua haujlwm nrog mapserver, txawm hais tias nws yooj yim heev, dhau los ua txoj thiab nyuaj rau cov haujlwm loj vim tias txhua yam nyob hauv .map. Qhov cuam tshuam loj tshaj plaws yog tias txhua yam ua tiav ntawm ko taw, xws li txhais kom meej txhua xim nyob rau hauv kev theming, thiab vim li ntawd cov cuab yeej xws li CartoWeb tshwm sim, uas ua haujlwm ntawm Mapserver tab sis nqa cov plugins thiab cov piv txwv nrog cov yam ntxwv ua rau qhov qub qauv no zoo li tus README thawj:

• Ua hauj lwm cais thav ntawv, nrog AJAX thiaj li ua tau rau lawv nyias
• Parse cov cai, muab ib tsab ntawv sau dua tshiab .map raws li cov kev txwv tsis muaj tseeb
• Dynamic xa cov xa tawm tsis tau ntxiv zog, txhais tau hais tias nws yog ib qho hluav taws xob txheej
• Online vector tsab, tam sim ntawv sau rau ntawm cache
• Download tau txheej hauv vector daim ntawv
• Xa rau Google ntiaj teb
• Tsim PDF ntawm kev xaav

Nyob rau hauv ib tom ntej no peb yuav saib zoo CartoWeb, ntawm no kuv tawm hauv qhov txuas mus rau tus piv txwv loj.
