Njengoba Mapserver usebenza

Isikhathi sokugcina sakhuluma kungani kokushesha MapServer nezisekelo zokufakwa. Manje ake sibone okuthile kokusebenza kwayo ekuzivocavoca namamephu wabangane baseChiapas.

  Lapho iphakanyisiwe khona

Kanye ezifakiwe Apache, lwemibhalo okushicilela MapServer ku C ifolda OSGeo4W okuzenzakalelayo ngqo: /

Ngaphakathi, kunamafolda ahlukile anezinhlelo zokusebenza kuya ngokufakiwe, kepha ifolda ezoshicilelwa kufanele ingene ngaphakathi kwe-apache. Kulokhu ifolda ebizwa nge-gis.

• Ngaphakathi ngaphakathi, ifolda yedatha iqukethe izendlalelo, i-orthophoto, njll.
• Kwifolda njll, kukhona amafonti ohlobo lwangempela asetshenziselwa amalebula, ngesandiso se-.ttf. Futhi nali ifayela le-txt elibaphakamisayo nelinye elichaza izimpawu.
• Futhi ekugcineni kufolda ye-httdoc iya kumakhasi wewebhu aphakamisa isevisi.
• 

Ikhasi lewebhu

Esibonelweni, ngizosebenzisa icala eliboniswe okokugcina. Ngokuyinhloko iqukethe ifayili lenkomba eliqondisa kwelinye libe nesandiso se-phtml, futhi lokhu kuphakamisa imisebenzi eyakhiwe ngaphezulu kwe-php namamephu. Ifolda iqukethe izithombe ezixhunywe ekhasini.

Uma siyibuka, i-phtml iyigobolondo nje elakhiwe ngamatafula, futhi ibiza imisebenzi ye-mapscript / php. Kufanele uvuke usebenzisa:

http://localhost/gis/gispalenque.phtml

Umphumela uboniswa ngezansi:

• kuya esikhungweni umsebenzi I-GMapDrawMap (),
• ngakwesokudla ukubiza Ikhibhodi ye-GMapDrawKeyMap (),
• ibha yesilinganiso ngezansi I-GMapDrawScaleBar (),
• futhi uma kwenzeka imisebenzi yokuthunyelwa, isimo esiphathelene ne-listbox uma (! IsHtmlMode ()) ivumelana "  kanye nezinqumo: ZOOM_IN, ZOOM_OUT, RECENTER, QUERY_POINT.

Sekuvele isebenza, isibonisi sibonakala kanje:

Amafayela we-.map

Inhlanganisela yencwadi yeMapserver yilokho okushiwo i-Apache, ethumela php i-mapscript bese lokho kuphuma ngalelo gobolondo. Kepha iningi lesayensi likumafayela we-.map, akumele lididaniswe nalawo akhiqizwe yiMapinfo, Manifold, noma Mobile Mapper Office enokwandiswa okufanayo.

Lawa mephu ngamafayela wombhalo, aqukethe imephu esefomini yesikripthi. Lokhu kungadalwa nezinhlelo zedeskithophu ezinjenge-Quantum GIS, uma uqaphela ukuthi kukhona eyodwa yemephu eyinhloko, eyodwa yeKeymap futhi emibili yezinsizakalo ze-OGC wms kanye ne-wfs. Ake sibone ukuthi i-mapscript isebenza kanjani:

• I-MAP ibonisa ukuthi uqala iskripthi

• I-SIZE ubukhulu bokubonisa
• I-SYMBOLSET ibonisa umzila wezimpawu
• I-EXTENT izixhumanisi zokubonisa. Uphawu # lusetshenziselwa ukwenza izichasiselo

Ukuphetha

Ngakho-ke, ukusebenza ne-mapserver, yize kulula, kuba yinkimbinkimbi futhi kukhawulelwe kakhulu emisebenzini emikhulu ngoba yonke into ikumephu. Okubi kakhulu ukuthi konke kwenziwa ngezinyawo, njengokuchaza umbala ngamunye kutimu, futhi ngenxa yalesi sizathu amathuluzi afana neCartoWeb avela, asebenza kuMapserver kepha alethe ama-plugins akhelwe ngaphakathi kanye nezibonelo ezinezici ezenza ukuthi le nguqulo yakudala ibukeke i funda kuqala:

• Sebenzisa amafremu ahlukene, nge-AJAX ukuze uvuselele ngokuhlukile
• Hlulela ikhodi, uma nje iskriphthi sibhala kabusha i-.map ngokusekelwe ezimweni ezilungiswayo
• Ukubuyela emuva kwe-Dynamic ngaphandle kokudinga ukuvuselelwa, njengokungathi kwakungqimba lombala
• Ukuhlelwa kwe-vector ku-intanethi, ukubhala ngokushesha kwesikhashana
• Layisha ungqimba kwifomu ye-vector
• Thumela ku-Google Earth
• Yenza i-PDF yokuthunyelwa

Esikhathini esilandelayo sizobheka i-CartoWeb, lapha ngishiya isixhumanisi sezibonelo ezisemqoka.
