Decidiéndonos ngu MapServer

Ngisebenzise ingxoxo yakamuva nesikhungo seCadastral ebesifuna ukushicilela amamephu aso, lapha ngifingqa izinto ezibaluleke kakhulu ukubuyisa ukutakulwa kwendaba emphakathini. Mhlawumbe ngaleso sikhathi kuzosiza umuntu ofuna ukuthatha isinqumo noma acele usizo lwe-geofumada.

Kungani i-MapServer

Isimo salowo muntu, owayehlose ukuhamba nge-GeoWeb Umshicileli, uBentley, ngoba wayesenayo ilayisense Iseva yokuthola, ukhokho walo, emuva kweminyaka engothuli.  Esinye isizathu esenza ukuthi uBentley abe nesithakazelo ukuthi imephu yabo i-Microstation Geographics, ne-VBA izicelo zokwakhiwa nokugcinwa kwamamephu e-cadastral.

Ngaphambilini kubhulogi (Ugly - Isikhathi eside njengoba umngane eshoyo) wabonisa indlela yokwakha isevisi yebalazwe lewebhu, besebenzisa okunye I-GIS, njengenye indlela yezindleko eziphansi. Ngiphinde ngakhuluma ngolunye usuku ngezinzuzo ze I-Geoweb Umshicileli kusuka eBentley njengesisombululo lapho kunesiliva eliningi. Lokhu ukunikeza ukuqhubeka kwalokhu okuthunyelwe okudala lapho Ngaqhathanisa phakathi kwezinhlelo ezihlukahlukene zokushicilelwa kwezincwadi ze-inthanethi.

Ngemuva kwengxoxo sithathe isinqumo sokuya kwiMapServer, isihloko engithemba ukusisebenzisa ezinsukwini ezimbalwa ezizayo. Ngendlela, qala ukuhlola amanye amapulatifomu womthombo ovulekile unyaka wonke, kepha endaweni yewebhu.

IMapServer ayisona isicelo se-GIS, ayizenzi ngisho nokuyikho, njengoba ikhasi layo lisho. Izalwe njengesinyathelo se-University of Minnesota, yingakho i-logo yayo ivela ekuhlanganeni kwemifula iMinnesota neMississippi. Namuhla kuyibhentshi kwinkonzo yemephu yewebhu esatshalaliswa kabanzi, mhlawumbe ngenxa yemvelaphi yayo ye-Anglo-Saxon. Njengoba lolu hlelo lokusebenza kukhona ezahlukene -kakhulu kakhulu kakhulu-, Ngithanda ukulula kwayo, okulula kubasebenzisi abasha; yonke imilingo ikusingatha ifayela le-.map elingasetshenziswa kusuka kuzinhlelo ezifana ne-QGis noma ukuqonda i-logic ukuze isebenzise amabalazwe ukusebenzisa izilimi ezifana ne-PHP, Java, Perl, Python, Ruby noma i-C #.

Izinhlelo zokusebenza eziningi zenziwa ku-MapServer "wakhonzaNjenge Chamaleon, Cartoweb, Ka-map, kanye nePmapper. Lokhu kunconyelwa abasebenzisi abanekhono elincane lekhodi, yize ukuqonda ukuqonda kokuqala kweMapServer kulungile.

Isibonelo esibonisiwe ukuthi, isibonelo nje somsebenzi esiwenzayo manje. Ngemvume yabo futhi bazi ukuthi le sevisi izotholakala emphakathini emasontweni ambalwa bese beyibona isebenza.

Lezo ezinye izinhlelo zokusebenza zewebhu zikhona

Ngenxa yalokhu, ngizosebenzisa iSisekelo njengesibonakaliso OSGeo, okungenye yemizamo yokudala kakhulu maqondana nokusimama kanye nokubeka izinga lomthombo ovulekile emkhakheni we-geospatial. Yize ngiyavuma ukuthi kukhona abanye.

• I-Mapbender, yenziwe yathandwa kakhulu, isetshenziswa njengeklayenti elincanyana ngeMapserver esimweni se-IDE Guatemala. Isizathu sesikhalazo sayo ukuthi yenzelwe i-PHP neJavaScript, inhlanganisela emibili esetshenziswa kakhulu kuwebhu namuhla.
• I-Mapbuilder, okwafika ukuphela kwayo enguqulweni engu-1.5 futhi ihlanganiswe ne-Open Layers. Into ye-AJAX… bekuwubuhle.
• Vula izendlalelo, uzibuza ukuthi ufuna ukuhlanganisa i-Google noma i-Yahoo Maps noma uthuthukise isikhashana ekuthunyelwe kwe-raster.
• I-Mapguide Opensource, ithandwa kakhulu ebudlelwaneni bayo ne-AutoDesk. Ukufela ngamandla, kunoma yikuphi ukunambitheka okufunayo.
• Isiqu, intuthu impela emazingeni. Ngamandla amaningi eYurophu. Ngenxa yokuzinza kwayo ekusekelweni kwe-GML, kuphakanyiswa njengenye indlela engathathi hlangothi yokuqalisa izinqubo zewebhu esenzweni HLELA.

Ezinye izixazululo ekukhulisweni kwe-OSGeo yilezi:

• I-Geoserver, okungcono kakhulu ukuthi ukuthuthukiswa kuphathelene neJava. Kunokuningi okunikezwa njenge-Layers Open uma uhlanganisa i-Google Amamephu, iGoogle Earth, i-Yahoo Maps, kuhlanganise ne-ArcGIS.
• I-Geomajas okufaka iklayenti encane, ideskithophu kanye newebhu.
• ImephuFish, ngokugxila phambili kuPyton kodwa mhlawumbe enye yezinto ezincane ezibhalwe ku-inthanethi.

Izinzuzo zeMephuServer

Ukuhambisana ngezindinganiso OGC. Mhlawumbe okungcono kakhulu, nakuba kulokhu cishe zonke izicelo zomthombo ovulekile zihle, okungenani ngokuphathelene ne-WMS, iWFS, i-WCS, i-GML.

• I-Web Map Service (OGC: WMS) i-1.0.0, i-1.0.7, i-1.1.0 ne-1.1.1
• Isevisi yesici sewebhu (OGC: WFS) i-1.0.0, i-1.1.0
• Insizakalo Yezokuxhumana Web (OGC: WCS) 1.0.0, 1.1.0
• Ulimi lwe-Geography Markup (OGC: GML) 2.1.2, I-3.1.0 Level 0 Profile
• I-Web Map I-Context Documents (OGC: WMC) i-1.0.0, i-1.1.0
• Umlobi Wezakhiwo Ezibunjiwe (OGC: SLD) 1.0.0
• Hlunga ukucaciswa kokufaka ikhodi (OGC: FES) i-1.0.0
• Isevisi Yokubheka Ukubuka (OGC: SOS) i-1.0.0
• Ukubheka kanye nokulinganisa (OGC: OM) 1.0.0
• SWE Common (OGC: SWE) i-1.0.1
• OWS Common (OGC: OWS) i-1.0.0, i-1.1.0

Ukuphaka imininingwane ngemihlahlandlela ye-Open Gis Consortium kuzokwenza noma yiluphi uhlelo lunamathele kuyo ngaphandle kwesithiyo esikhulu. Kusuka ku-AutoDesk Civil3D, ArcGIS. Imephu yeBentley, eya ku-gvSIG, QGis, njll. Ngisho neGoogle Earth / amamephu nge-wms.

Ukuqhathanisa nalezicelo engangizisebenze ngaphambilini (i-GeoWeb Publisher and Manifold GIS), i-MapServer ibadlula ngokwenza ukusabalalisa okuningiNgenxa yalokho, ikhasi lakho linemininingwane eyanele, izibonelo ezithuthukisiwe, ingasaphathwa eyomphakathi wabasebenzisi. Endabeni ye-GWP kufanele usebenze kakhulu ngezipikili zakho futhi okukhona nge-Manifold ngeSpanishi kuncane kakhuluushiye ngaphandle Wena egeomates ukuze ungangeni ekuphambene-.

El ukusekelwa kwedatha kuyisimangaliso. Akusilo izulu kepha kusondele ngokwanele:

• Idatha yeVector noma yeGeodatabase: Amafayela Wokwakheka, i-GML, i-PostGIS nezwe elilodwa ngaphezulu nge-OGR, kufaka phakathi i-DGN.
• Idatha yeRaster: i-georeferenced Tif nanoma yini esiyifunayo nge-GDAL.
• Kusuka kokukhipha, ungenza i-jpg, i-png, i-pdf, futhi-ke, amazinga we-OGC.

Khona-ke kukhona ukwesekwa kwe-multiplatform. IMapServer ingasebenza ngaphezulu kwe-IIS, okwenza kube lula kubasebenzisi beWindows / PC. Futhi ku-Apache, engasebenza ngayo kuWindows nakuLinux ngokumangalisayo, hhayi kuphela ukukhonza idatha kepha ukuzulazula. Endabeni yeManifol
d, incwadi kuphela i-IIS, uma ukhuluma nabo nge-Apache it hits ukuminyanisa, nakuba kukhona labo ababenzile i-pirouettes. Futhi esimweni seBentley, yiWindows kuphela, noma isibonisi sewebhu yi-ActiveX esebenza ku-Internet Explorer kuphela, ngaphandle kokuthi ibhemiswe. IDPR kuya kwi-sublime e-space cartridge.

Akudingeki ukusho, akusebenzi ukhokhela amalayisensi. Ilayisense eneManifold Universal ibizoba ngama- $ 600, leyo yeBentley GWPublisher ye-US $ 10,000 enabasebenzisi abalinganiselwe futhi ukube bekungeye-GIS Server ye-US $ 15,000 kuya phezulu.

Ekugcineni, ngibona inzuzo enkulu ku ukuthuthukiswa. Ukuthola umuntu osebenza iMapServer akulula kangako, kepha kulula kakhulu kunezinye izinhlelo zokusebenza, noma ukude njengoba senza manje. Umthuthukisi owazi amathumbu we-Bentley GWPublisher akulula kangako ukukuthola, kufanele azi iProject Wise, Geographics, Microstation VBA neBentley Map ukuze asizakale ngokuthuthuka okuqinile kwi-Bentley Geospatial Server (Nakuba ngivuma ukuthi kunezinto ezinhle kakhulu ezenziwe lapho). Umqambi we-GIS we-Manifold, unzima kakhulu yize kuyi-.NET kuphela, futhi eyodwa evela ku-GIS Server, nakanjani izokhokhisa ngokususelwa ekutheni ilayisense ibiza malini.

Ungayifaka kanjani izinyathelo ze-5

Azikho izinyathelo eziningi, kanye nokuqala kukaGenesise:

1. Landa i-OSGEO4W kusuka lapha
2. Faka, i-Minimum MapServer, i-Apache nesibonelo.
3. Faka i-Apache bese udala isevisi (noma uphakamise isiqondisi nge-IIS).
4. Phakamisa isevisi
5. Sebenzisa isibonelo kusiphequluli

Yebo, njengeGenesis, phakathi kwamavesi 1 no-2 kunezinto eziningana ezenzekile ekuhlubukeni kukaSathane. Ngokuvamile ukukhulisa insiza nge-http: // localhost / noma kungena impi yayo, kepha kuyafundwa.

Kuzoba okulandelayo ukuthi sizoyichaza.
