Kusankha ndi MapServer

Pogwiritsa ntchito zokambirana zaposachedwa ndi bungwe la Cadastral lomwe limafuna kufalitsa mamapu ake, apa ndikufotokozera mwachidule zinthu zofunika kwambiri kuti abwezeretse nkhaniyi kumudzi. Mwina panthawiyo zingathandize munthu amene akufuna kupanga chisankho kapena kupempha thandizo la geofumado.

Bwanji MapServer

Chochitikacho chinali munthu wina, yemwe ankafuna kuti apite ndi GeoWeb Publisher, Bentley, chifukwa anali ndi chilolezo Seva Yotulukira, kholo la uyu, kumbuyo kwa zaka zapfumbi.  Chifukwa china chimene iwo anali nacho chidwi ndi Bentley ndi chakuti mapu awo ali pa Microstation Geographics, ndi VBA zopempha zokonza ndi kukonza mapu a cadastral.

Poyamba pa blog (Osauka - Nthawi zambiri monga mnzanu akunenera) anasonyeza m'mene angapangire mapu a mapu, kugwiritsa ntchito zojambulidwa GIS, ngati njira yotsika mtengo. Ndinalankhulanso tsiku lina za zabwino za Geoweb Publisher kuchokera ku Bentley ngati yankho pakakhala ndalama zambiri. Izi zikupitiliza kupitilira positi yakale ija momwe Ndinayerekezera pakati pa mapulogalamu osiyanasiyana pa mapu a pa intaneti.

Titatha kukambirana tidaganiza zopita ku MapServer, mutu womwe ndikuyembekeza kuugwiritsa ntchito masiku angapo otsatira. Mwa njira, yambani kuyesa mapulatifomu ena otseguka kwa chaka chonse, koma pamalo ochezera a pa intaneti.

MapServer si ntchito ya GIS, sichidziyesa ngakhale kukhala, monga tsamba lake limanenera. Adabadwa ngati njira yaku University of Minnesota, chifukwa chake logo yake imachokera pamtsinje wa Minnesota ndi Mississippi. Lero ndi chilinganizo pamapu omwe amagawidwa kwambiri pamasamba, mwina chifukwa cha chiyambi cha Anglo-Saxon. Monga ntchito imeneyi pali osiyanasiyana -kwambiri kwambiri--, Ndimakonda kuphweka kwake, kosavuta kwa ogwiritsa ntchito atsopano; matsenga onse akugwiritsira ntchito fayilo ya .map yomwe ingachititsidwe kuchokera ku mapulogalamu monga QGis kapena kumvetsa malingaliro kuti mapulogalamu azigwiritsa ntchito zinenero monga PHP, Java, Perl, Python, Ruby kapena C #.

Mapulogalamu ena apangidwa pa MapServer "anatumikira”Monga Chamaleon, Cartoweb, Ka-map ndi Pmapper. Izi zimalimbikitsidwa kwa ogwiritsa ntchito osakhazikika pamakhodi, ngakhale kumvetsetsa lingaliro loyambirira la MapServer ndibwino.

Chitsanzo chowonetsedwa ndikuti, chitsanzo chabe cha ntchito yomwe tikugwira pano. Ndi chilolezo chawo ndipo akudziwa kuti ntchitoyi ipezeka kwa anthu m'masabata angapo ndipo atha kuyiona ikugwira ntchito.

Ntchito zina zamakono zilipo

Pachifukwa ichi, ndigwiritsa ntchito Maziko monga zolembera OSGeo, yomwe ndi imodzi mwazinthu zopanga kwambiri potukula ndi kukhazikitsa magwero otseguka m'munda wa geospatial. Ngakhale ndimavomereza kuti alipo ena.

• Mapbender, yotchuka kwambiri, yogwiritsidwa ntchito ngati kasitomala wowonda ndi Mapserver pankhani ya IDE Guatemala. Chifukwa chake ndikupemphanso ndikuti idapangidwa kuti izikhala PHP ndi JavaScript, zophatikiza ziwiri zomwe zimagwiritsidwa ntchito kwambiri pa intaneti masiku ano.
• Wopanga mapulani, zomwe zinadza mapeto ake mu mtundu 1.5 ndikuphatikizidwa mu Open Layers. Chinthu cha AJAX… chinali chokongola.
• Tsegulani Zigawo, ndikudabwa ngati mukufuna kuphatikizana ndi Google kapena Yahoo Maps kapena kusintha chache mu polojekiti ya raster.
• Mapguide Opensource, yotchuka kwambiri chifukwa cha ubale wake ndi AutoDesk. Olimba kufera, mulimonse momwe mungafunire.
• Digiri, utsi wambiri pamiyezo. Ndizotheka zambiri ku Europe. Chifukwa chokhazikika pothandizidwa ndi GML, akuti ndi njira yandale yopezera njira zapaintaneti. AMALIMBITSA.

Zina zothetsera makina a OSGeo ndi awa:

• Geoserver, kuthekera kwake kwakukulu ndikuti chitukuko ndi cha Java. Ndi zambiri zomwe mungapereke monga Open Layers pamene mukuphatikiza Google Maps, Google Earth, Yahoo Maps, kuphatikizapo ArcGIS.
• Geomatics zomwe zimaphatikizapo wochepa chithandizo, kompyuta ndi webusaiti.
• MapuFish, ndi cholinga choyang'ana kwa Pyton koma mwina chimodzi mwazolembedwa (pa intaneti).

Mapu Mapulogalamu

Kugwirizana ndi miyezo OGC. Mwina zabwino kwambiri, ngakhale kuti pafupifupi zonsezi zogwiritsidwa ntchito moyenera zili zabwino, makamaka pa WMS, WFS, WCS, GML.

• Mapu a Mapu a Web (OGC: WMS) 1.0.0, 1.0.7, 1.1.0 ndi 1.1.1
• Webusaiti Yopatsa Utumiki (OGC: WFS) 1.0.0, 1.1.0
• Webusaiti Yowonjezera Webusaiti (OGC: WCS) 1.0.0, 1.1.0
• Chilankhulo Chojambula Chisokonezo (OGC: GML) 2.1.2, 3.1.0 Level 0 Profile
• Mapu a pa Web Context Documents (OGC: WMC) 1.0.0, 1.1.0
• Mndandanda wazithunzi (OGC: SLD) 1.0.0
• Sungani Kutsindika Kulembera (OGC: FES) 1.0.0

Kutumizira deta kudzera pa malangizo a Open Gis Consortium kudzapangitsa pulogalamu iliyonse kumamatira popanda chopinga chilichonse. Kuchokera ku AutoDesk Civil3D, ArcGIS. Mapu a Bentley, kupita ku gvSIG, QGis, ndi zina zambiri. Ngakhale Google Earth / mamapu kudzera pa wms.

Poyerekeza ndi mapulogalamu omwe ndagwira nawo kale (GeoWeb Publisher ndi Manifold GIS), MapServer amawaposa iwo kusokonezeka kwakukuluZotsatira zake, tsamba lanu lili ndi chidziwitso chokwanira, zitsanzo zopangidwa, osatchulapo omwe amagwiritsa ntchito. Pankhani ya GWP muyenera kugwira ntchito kwambiri ndi misomali ndipo zomwe zilipo za Manifold mu Spanish ndizochepa -kuchoka kunja inu egeomates kotero kuti musalowe mu kutsutsana-.

El chithandizo cha deta ndizodabwitsa. Si kumwamba koma kwayandikira kwambiri:

• Zambiri za Vector kapena Geodatabase: Mafayilo amtundu, GML, PostGIS ndi dziko lina kudzera pa OGR, kuphatikiza DGN.
• Raster data: georeferenced Tif ndi chilichonse chomwe tikufuna kudzera pa GDAL.
• Kuchokera ku chiwongoladzanja, mukhoza kupanga jpg, png, pdf komanso, OGC miyezo.

Ndiye pali thandizo la multiplatform. MapServer imatha kuthamanga pamwamba pa IIS, zomwe zimapangitsa kukhala kosavuta kwa ogwiritsa ntchito Windows / PC. Komanso pa Apache, yomwe imatha kuyendetsa pa Windows ndi Linux modabwitsa, osati kungogwiritsa ntchito deta komanso kuyenda. Pankhani ya Manifol
d, buku lokha la IIS, ngati muwauza za apache imalumikiza kusokonezeka, ngakhale pali ena omwe apanga zawo pirouettes. Pankhani ya Bentley, ndi Windows yokha, ngakhale chiwonetsero cha intaneti ndi ActiveX yomwe imangogwira pa Internet Explorer, pokhapokha ikasuta IDPR kupita kumalo otetezeka mu cartridridge.

Zosafunika kunena, izo sizikusamala kulipira chilolezo. Chilolezo chokhala ndi Manifold Universal chikhoza kukhala $ 600, ya Bentley GWPublisher ya US $ 10,000 ndi ogwiritsa ntchito ochepa komanso ngati GIS Server ya US $ 15,000 kupita pamwamba.

Pomalizira, ndikuwona mwayi waukulu chitukuko. Kupeza munthu amene akugwira ntchito ya MapServer sikophweka, koma ndikosavuta kuposa momwe mungagwiritsire ntchito, ngakhale kutali ngati momwe tikuchitira pano. Wopanga mapulogalamu omwe amadziwa kulimba mtima kwa Bentley GWPublisher sikophweka kupeza, ayenera kudziwa Project Wise, Geographics, Microstation VBA ndi Bentley Map kuti agwiritse ntchito mwayi wolimba pa Bentley Geospatial Server (Ngakhale ndikuvomereza kuti pali zinthu zabwino zomwe zimachitika kumeneko). Wopanga ma GIS ochulukirapo, ovuta kwambiri ngakhale ali okha .NET, ndipo imodzi yochokera ku GIS Server, imalipira molingana ndi kuchuluka kwa chiphatso.

Momwe mungayikiritsire muzitsulo za 5

Palibe zochitika zambiri, komanso chiyambi cha Genesis:

1. Tsitsani OSGEO4W kuchokera pano
2. Ikani izo, mapu MapServer, Apache ndi chitsanzo.
3. Ikani Apache ndikukonzekera (kapena yongolani bukhu kudzera pa IIS).
4. Kwezani utumiki
5. Kuthamanga chitsanzo mu msakatuli

Inde, monga Genesis, pakati pa vesi 1 ndi 2 pali zinthu zingapo zomwe zidachitika pakupanduka kwa Satana. Nthawi zambiri kupeza ntchitoyo kudzera pa http: // localhost / kapena kumakhala pankhondo yanu, koma mumaphunzira.

Zidzakhala mu tsiku lotsatira zomwe tidzazifotokoze.
