Geospatial - GISI-GvSIGqgis

Ngabe iJava Worth Learning?

Ngaphandle kwe-OpenOffice, Vuze, Woopra, noma ama-applets asetshenziswe kwamanye amakhasi ewebhu, ahlelwe kakhulu kumasistimu eselula, i-TV, GPS, ama-ATM, izinhlelo zebhizinisi kanye namakhasi amaningi esiwafaka nsuku zonke asebenza ku-Java.

Ishadi elandelayo ibonisa indlela Java ubuchwepheshe has isizinda eqinile kancane kancane kusukela 2006 2011 kuqhathaniswa C # .net, PHP noRuby, mhlawumbe kuthathwe elandelayo umsebenzi intengiso.

izibaloJava

Endabeni imvelo geospatial, C ++ futhi Java kukhona imihlaba letimbili letinkhulu zakhelwe Open zokusebenza Umthombo; Umdwebo olandelayo ubeka ngokufingqiwe okuthile, isihloko post ngigxila ekwandiseni ku ze-Java kodwa unganakile (engesiyo), kusukela ohlangothini Java ukuze C ++ weqiwe endaweni 15 ubuhlobo ukuze 10.

Izinhlelo ze-GIS ku-C ++

Izinhlelo ze-GIS ku-Java

Ezingeni ledeskithophu

 

  • GIS Quantum. Okusetshenziswe kakhulu kwimvelo ye-Anglo-Saxon, kuvame ukuhambisana noGrass.
  • GRASS. Uhlelo oludala kakhulu lwe-OpenSource, olubekwe phambili ku-raster.
  • Saga. Wazalelwa eJalimane, ngokugxila phambili ocwaningweni.
  • Isi-Ilwis. Isinyathelo esazalelwa eNetherlands, futhi yize sivela maphakathi namashumi ayisishiyagalombili, ukuthuthuka kwaso ngaphansi kokuhlanganiswa komphakathi kubi.

 

  • gvSIG.  Mhlawumbe isicelo esisatshalaliswa kabanzi se-OpenSource endaweni yaseSpain, futhi mhlawumbe esinombono onolaka wamazwe omhlaba jikelele. Kuze kube manje izindatshana zami ezingaphezu kwe-100 zikhomba kuleli thuluzi.
  • SEXTANTE. Kukhuthazwe yi-University of Extremadura, umphelelisi omkhulu we-gvSIG, yize kunemitapo yolwazi ye-OpenJump, iKosmo futhi ibuye isebenzisane ne-GRASS.
  • uDig. Lokhu intuthuko ehlanzekile, uma ingasatshalaliswa ngamandla amakhulu, eyenziwe yinkampani efanayo yePostGIS, iGeoServer neGeotools.
  • I-Kosmo. Ngisebenza kwa-OpenJump, owazalelwa eSpain.
  • I-OpenJump. Ifa lesinyathelo saseCanada esibizwa ngeJump, esasimisiwe.
  • I-CatMDEdit. Lesi isihleli semethadatha.

Ezingeni leseva

  • ImephuServer. Isabalale kakhulu, yize inenqubekela phambili ehamba phambili ekuthuthukisweni nasekuhlanganisweni kuneGeoserver.
  • ImephuGuide OS. Isekelwa yi-AutoDesk, inamandla kakhulu.

 

  • GeoServer. Kungaba iseva yedatha esetshenziswa kakhulu.
  • GeoNetwork. Kuyimenenja yekhathalogi ye-metadast, ekahle nge-geoportal noma indlu yokuhlanza.
  • I-Degree. I-Initiative ezalwa eNyuvesi yaseBonn, eJalimane, enekhono elilingana neGoSServer.

Ezingeni lezincwadi

 

  • GEOS
  • I-PROJ4
  • I-FDO
  • I-GDAL / OGR

 

 

  • Geotools
  • I-GeoAPI
  • I-Baltik
  • I-JTS
  • I-WKBj4

inkambo-ye-javaOkungenhla, okungenani i-5 yalezo ezakhiwe ku-Java zibalwa njengamaphrojekthi we-OSGeo isisekelo, amanye ekukhulisweni, ekufuneni ukusimama nokuhambisana.

Kungaba nentshisekelo ukuba netafula eliyindilinga lochwepheshe bezinhlelo ukuze bakhulume ngokuthi kungani bekhetha noma bezonda iJava, mhlawumbe kungaxoxwa ngokuthi ngabe ama-Pointers ayenza yini inqubo ibe lula noma cha, uma ukufundwa kokufunda okuningi kuzoba nenzuzo kunezinye izilimi uma kungekho mshini obonakalayo, uma ukuphepha kuhlobene. ; kodwa entweni eyodwa bonke bangavumelana:

Iqiniso lokuba yi-multiplatform, ngoba izinhlelo zingasebenza kuWindows, Linux, Solaris nakuMac (ukuziba inkani yakamuva kaSteve Jobs). Lokhu kukwenza ukuhehe kwezicelo ezinesilinganiso somhlaba wonke, lapho abasebenzisi bazosebenzisa amasistimu wokusebenza ahlukile neziphequluli, ukuxazulula cishe yonke into ngomshini odumile we-Virtual ukuthi ngaphandle kokwenza imisebenzi eminingi, kuxazulula inkinga yokuphatheka futhi kunikeze ukuhlunga okuphephile phakathi kwe- iklayenti neseva.

Futhi iqiniso lokuthi yomthombo ovulekile kuyisici ukuhlola, nakuba Oracle atholwe ILANGA (Java kunjiniyela), futhi abathile bakungabaze ukuthi kuzokwenzekani esikhathini esizako nge MySQL (ilayisensi GPL), cishe akekho umuntu okungabazayo esizayo Java ulimi.

Mhlawumbe okuqale i-Green Teen njengephrojekthi ehlulekile ukusebenza kumathelevishini futhi i-VHS ayisafani nalokho okuzuzwe yiJava ekubekeni, yize ikwenza ngezinhloso. Kuze kube manje, kunezinhlelo ezintathu ze-Java:

 

imikhiqizo ye-java

I-J2SE (I-Standard Edition), yiyona evame ukusetshenziswa kakhulu ekwakhiweni kwezicelo ezihanjisiwe nama-apulas.

I-J2EE (I-Enterprise Edition), ngokuvamile ngamathuluzi wezamabhizinisi amaningi, amasevisi asekela kude kanye nokuhwebelana kwe-elektroniki.

I-J2ME (i-Micro Edition), okuyiziphi izinhlelo zokusebenza zefoni, ama-GPS namabhokisi e-digital TV akhiwe.

Learn21 y Globalmentoring ziyizibonelo zamakilasi ajwayelekile lapho ungafunda khona iJava.

 

Ngakho, ubuyela embuzweni wokuqala, uma iJava kufanelekile ukufunda ...

Yebo.

Umbhali, umcwaningi, uchwepheshe wamamodeli wokuphathwa komhlaba. Ubambe iqhaza ekucabangeni nasekusetshenzisweni kwamamodeli afana nalawa: Isistimu Kazwelonke Yokulawulwa Kwezakhiwo i-SINAP e-Honduras, Imodeli Yokuphatha Yomasipala Abahlangene e-Honduras, Imodeli Edidiyelwe Yokuphathwa Kwe-Cadastre - Registry e-Nicaragua, Uhlelo Lokuphatha lwe-Territory SAT e-Colombia. . Umhleli webhulogi yolwazi lwe-Geofumadas kusukela ngo-2007 futhi umdali we-AulaGEO Academy ehlanganisa izifundo ezingaphezu kwe-100 ngezihloko ze-GIS - CAD - BIM - Digital Twins.
