Monga Mapserver ntchito

Nthawi yapitayi yomwe tinayankhula pazifukwa zina MapServer ndi maziko okhazikitsa. Tsopano tiwone zina mwa momwe amagwirira ntchito pochita masewera olimbitsa thupi ndi mapu a abwenzi a Chiapas.

  Kumene kuli kukwera

Apache ikadakhazikitsidwa, zolemba zosasinthika za MapServer ndizomwe zili OSGeo4W pamwambapa C: /

M'kati mwake, muli mafoda osiyanasiyana okhala ndi mapulogalamu kutengera zomwe zaikidwa, koma chikwatu chofalitsa chiyenera kulowa mkati mwa apache. Poterepa chikwatu chotchedwa gis.

• Ndiye mkati, foda ya deta ili ndi zigawo, orthophoto, ndi zina zotero.
• Mu chikwatu cha zina, pali mafayilo amtundu woyenera omwe amagwiritsidwa ntchito pamalembawo, ndikuwonjezera kwa .ttf. Pano pali fayilo ya txt yomwe imawakweza iwo ndi ina yomwe imatanthauzira zizindikilo.
• Ndipo potsiriza mu fayilo httdocs pitani masamba omwe akukweza utumiki.
• 

Tsamba la intaneti

Mu chitsanzo, ndigwiritsa ntchito mlandu womwe wasonyezedwa komaliza. Imakhala ndi fayilo ya index yomwe imaloza kumodzi ndi kufutukula kwa phtml, ndipo izi zimakweza ntchito zomangidwa pamwamba pa php ndi mamapu. Foda ili ndi zithunzi zolumikizidwa patsamba.

Tikayang'ana, phtml ndi chipolopolo chomwe chimamangidwa kuchokera pa matebulo, ndikuyitanitsa ku mapacript / php ntchito. Muyenera kudzuka pogwiritsa ntchito:

http://localhost/gis/gispalenque.phtml

Zotsatira zikuwonetsedwa pansipa:

• mpaka pakati pa ntchito GMapDrawMap (),
• kumanja kumene kuyitanidwa Keypap GMapDrawKeyMap (),
• bhala laling'ono pansipa GMapDrawScaleBar (),
• ndipo ngati ntchito yothandizira, chikhalidwe chokhudza listbox ngati (! IsHtmlMode ()) echo "  ndi zosankha: ZOOM_IN, ZOOM_OUT, RECENTER, QUERY_POINT.

Kuyambira kale, mawonetsedwe akuwoneka ngati awa:

Mafayi .map

Kuphatikizidwa kwa Mapserver kabukuka ndi zomwe apache akukweza, zomwe zimatumiza php kudutsa mapscript ndipo izo ndiye zimatuluka kudzera mu chipolopolocho. Koma sayansi yambiri ili m'mafayilo a .map, osasokonezedwa ndi omwe amapangidwa ndi Mapinfo, Manifold, kapena Mobile Mapper Office ndi kufalikira komweku.

Mapu awa ndi mafayilo amawu, omwe amakhala ndi mapu amtundu wa script. Izi zitha kupangidwa ndi mapulogalamu apakompyuta monga Quantum GIS, ngati mungazindikire kuti pali mapu akulu, imodzi ya Keymap ndi iwiri yothandizira ma OGC wms ndi wfs. Tiyeni tiwone momwe mapukusi amagwirira ntchito:

Kutsiriza

Chifukwa chake, kugwira ntchito ndi mapserver, ngakhale kuli kosavuta, kumakhala kovuta komanso kocheperako pantchito zazikulu chifukwa chilichonse chili mu .map. Chosavuta kwambiri ndikuti chilichonse chimachitika ndi phazi, monga kutanthauzira mtundu uliwonse pamutu, ndichifukwa chake zida monga CartoWeb zimatuluka, zomwe zimagwira ntchito pa Mapserver koma zimabweretsa mapulagini omangidwa ndi zitsanzo ndi mawonekedwe omwe amachititsa kuti mtundu wakalewu uwoneke a readme poyamba:

• Gwiritsani ntchito mafelemu osiyana, ndi AJAX kuti muwatsitsimutse mosiyana
• Lembetsani kachidindo, munaperekanso zikalata zolemba .map pogwiritsa ntchito zifukwa zosinthika
• Mphamvu imabweretsanso kusamukirako popanda kubwezeretsa, monga ngati chingwe chodutsa
• Mndandanda wamakono pa intaneti, zolembera mwamsanga pa cache
• Tsitsani zosanjikiza mu vector mawonekedwe
• Tumizani ku Google Earth
• Pangani pulogalamu ya kutumizidwa

M'kutsatira tidzayang'ana CartoWeb, apa ndikusiya kulumikizana kwa zitsanzo zazikulu.
