Kwadzidzidzi GIS, koyamba

qgis Ngati abwenzi a gvSIG iwo amakwaniritsa lonjezo lawo, Lolemba lotsatira 27 ya Julayi tidzakhala ndi chikhomo chokhazikika cha 1.9. Kwa tsopano mayesero akhala abwino, molingana ndi buku lomwe likuwonekera mndandanda wogawa. Pamene Lolemba ifika, panthawi yomwe ndikuyembekeza kudzakondwera kukwaniritsidwa kwa mawuwo, podziwa kuti pulogalamu yabwino yomwe omanga ayenera kuitenga, tiyeni tione Quantum GIS ngati mbalame zodya nyama.

QGIS inakhazikitsidwa mu C ++ pogwiritsa ntchito Qt toolkit, ikuyenda pa Windows, Mac ndi Linux. Ntchitoyi imayamba mu May kuchokera ku 2002, mothandizidwa ndi zinenero za 26 ndipo chilolezo chake ndi GPL.

Tidzayesa vesi la 1.02 lomwe lasiya ine kukhala wokhutira kwambiri kuti ndikhale chida chogwiritsira ntchito kwaulere, mukhoza kuchilandira kuchokera kulumikizana uku ndipo izi ndizo tsamba lovomerezeka la Qgis.

Kuwonekera kwa Quantum GIS

Zojambulajambula ndi zojambulajambula ndizowomboledwa kwambiri, sizimakhudzira usability, koma ili ndi kukoma kampani (imagulitsa) pakupereka. Zomwezo Ndinatsutsa kale ya gvSIG, chifukwa nthawi ina maonekedwe ake ndi kusiyana kwake kwa chilengedwe zinapangitsa manejala kundiuza "imawoneka ngati pulogalamu yamakono, zithunzi zina zikuwoneka kuti zapangidwa ndi Paintbrush ya 8 bits".

Koma mu izi chikhalidwe, QGIS ikupita bwino, ngakhale pang'onopang'ono mungasankhe pakati pazithunzi zosiyana siyana za 3 za zithunzi zojambula bwino bwino kwambiri, pokhapokha podutsa mbewa pa mutuwo ikuwonetsa momwe mawonekedwe angayang'anire.

Zochititsa chidwi za Quantum GIS

QGIS imafuna Grass kwa ntchito zambiri zomwe chida ichi chaphatikizidwa bwino, chabwino kwambiri kuti musayese kuyesayesa. Mukayamba QGIS ndipo simungapeze, yikani; Pankhaniyi ndikupanga ndemanga popanda kuphatikiza Grass. Pofuna kutsegula data ya Grass, chifukwa sichidaikidwe polojekitiyi itsekedwa, kotero sindikupangira ntchito popanda kuyika zida zonsezo.

qgis Mifupi, Malamulo ambiri ali ndi kalata yoperekedwa, kuti muthe kukweza ntchitoyo polimbikira kalata iyi. Izi ndi zothandiza kwambiri, ndikukumbukira kuti mu AutoCAD inali imodzi mwa njira zabwino pamene pafupifupi lamulo lirilonse linkachitidwa kudzera mu khibhodi.

Zowonongeka, kumanzere kwa mapu ali ndi mapu omwe amasonyeza malo operekera, ndi mafananidwe m'njira ziwiri. Zothandiza kwambiri, mukhoza kusankha zomwe mukufuna kuziwona mwachidule, ndipo mukhoza kuzisiya ngati zenera lakuyandikana ndi kukula kwake.

qgisChophimba cha mbali, chabwino kwambiri, mukhoza kukokera mapulagini monga malemba kumbuyo, akhoza kuyandama, ndipo ndi batani lophweka lamanja lokhazikitsa kapena loletsa. Komanso kugwiritsira ntchito m'lifupi ndikuthamanga kokha osati kumanja lakumanzere koma m'modzi wotsika.

Pansi pansi, pakuwonetsa tebulo lalingaliro, likuwoneka m'deralo, koma likhoza kuyandama. Zogwira ntchito kwambiri, ndizomwe mungasankhe kuti muzitsanulira mizere yomwe mwasankha ndikusintha m'lifupi la zipilala ndi losavuta mbewa. Komanso pamutu wapansi muli ntchito za kufufuza ndi kusankha, zofanana ndi momwe GIS Yambiri imakhalira, pokhapokha ndi barolo yovomerezeka.

quantum gisKukonzekera kwa mawonekedwe a mawonekedwewa kumapangitsa kukhala kopindulitsa kwambiri, mafelemu oyandama ndi abwino, amandikumbutsa kwambiri Microstation, chifukwa pa nkhaniyi, zizindikiro zenera zingathe kuwonetsedwa popanda kukhudza ntchito ina.

Kusanthula deta, ali ndi mbali zofunika pakufufuza ndi kufufuza zomwe munthu angafunike, poyang'ana pali zinthu zosangalatsa zomwe ndimakonda kuziwona nthawi ina, chifukwa mapulagulu a Ftools akuphatikizapo malo oyendetsera nthaka, ma hydrological pakati pa ena.

qgis Maapulogalamu owonjezeraNgati ntchito iliyonse gpl, phindu lanu liri mu mapulagini kuti pang'onopang'ono kupanga mdera (ngakhale ntchito osati kukhala mu Java), ndi kusakhulupirika kumabweretsa zikuluzikulu ndipo amaoneka kuti ndi ochepa koma zing'onozing'ono monga amaoneka: loadable zigawo WFS, katundu ndi MapServer, mumpanda wa ntchito, kuwonjezera thandizo maganizo monga kumpoto, ang'ono ndi kukopera, koma-delimited malemba, ali dxf Converter SHP pulogalamu yowonjezera kwa mafano georeferencing, kutonthoza GPS, Python kutonthoza, gululi ndondomeko , ndi zina zotero. Koma chinthu chabwino kwambiri ndicho kusankha kutsegula mapulagulu a Grass omwe ndi nkhani yosiyana. Mofananamo ndi zomwe zimachitika ndi gvSIG ndi Sextante ngakhale kukula kwa Grass kukulemekezeka, chimodzi mwa zipangizo zakale za GIS.

N'zochititsa chidwi OGR Converter, amene angathe kutembenuza zigawo pakati akamagwiritsa osiyana, monga SHP, DGN, GPX, GML, csv, KML, MapInfo ndi BD danga kudzera ODBC, MySQL, PostgreSQL, mwa ena.

Za zabwino: dxf kwa shp ndi kml ku dxf, zofunika koma osati ndi mapulogalamu ena a kulipira.

Zofunikira, monga zida zina, mukhoza kupanga zizindikiro zamkati, magulu a zigawo, zigawo zili ndizomwe zimakhala zochepa komanso zowonjezereka zowonongeka, zosavuta kuwonjezera makonzedwe ndi machitidwe; Ngati ali ndi shp zigawo, ngati ali ndi prj, Qgis amapulumutsa zimenezi. Zambiri mwazinthu zikuphatikizapo kupita patsogolo, zomwe timaganiza kuti ndi zabwino kwambiri.

Ndiponso tebulo ili likuyandama ndipo mukhoza kusinthanitsa m'lifupi ndi kutalika kuti mulawe. Ngakhale gulu ili ndi ena akhoza kutsegulidwa ngati ntchito yosiyana.

quantum gis Chimakumbukiranso zinthu zomwe zimawoneka zosavuta koma zomwe zili zothandiza kwambiri, monga kuyeza kwa kutalika kwake, komwe kumawonetseratu m'magulu, omwe ndi mtunda wa gawo lirilonse.

Kufikira ndi kusindikiza deta

Mukhoza kusunga vector data shp, gml, Mapinfo ndi ddf, ngakhale mutha kusintha deta kuchokera ku machitidwe ena kudzera mwa oGR converter. Kuwonjezera pa zigawo za vector kudzera WFS ndi PostGIS. Cholowa, chimakulolani kuti mufotokoze chikhalidwe cha encoding pamene mutsegula wosanjikiza.

Koma zigawo za raster, zimathandizira zambiri, kupatula WMS. Kuphatikizanso apo, zikuphatikizapo kuwerenga ma OGC WFS, WCS, CAT, SFS, ndi GML.

Kupanga zigawo zatsopano za vector zingathe kupyolera maofesi a mawonekedwe a OGR kapena Grass. Ntchitoyi imasungidwa ngati XML ndi kukula kwa qgs, kumene kusintha kwa zigawo kumasungidwa kalembedwe ka gvSIG.

Koma kusintha deta ntchitoyo katundu zasungidwa specifications monga mwandondomeko dongosolo, mayunitsi, mwatsatanetsatane za decimal, kuwapangitsa kusintha topological, kuwapangitsa kapena kuchepetsa toyalana polygons mu wosanjikiza chomwecho ndi zinthu chithunzithunzi (mtundu ndi kulekerera) pa gawo lililonse lomwe likupezeka pulojekitiyi. Chotsatiracho n'chosangalatsa, ngakhale kuti ndinakhumudwa kuti ndilo gawo limodzi ndi la vertex. Apanso, Grass ayenera kukhala wolondola pa izi.

Ndinayesa kusintha ndondomeko, ndikuika vertex, koma ndinazichepetsako, pokhapokha pokhapokha kuti kunali kofunika kuti ndiwonjezere njira zowonjezera (pepani chifukwa cha kusokonezeka kwanga, ndi nthawi yoyamba yomwe ndimasewera chidole ichi). Ndiziwona nditatha kutsegula zipangizo za Grass. Kapena sizikuwoneka kuti pali njira ngati angapo akukonzekera wosanjikiza panthawi imodzi, amene amapambana choyamba. chabwino!

Zotsatira za data

Pogwiritsa ntchito mwatsatanetsatane, pali njira yosungira malingaliro monga chithunzi, ndi pulojekiti yosindikizira mofulumira, koma mosiyana ndi gvSIG, ilibe dongosolo la ArcView layout layout; koma zolemba zomwe ndikuwoneka kuti zimachokera ku tsitsi langa, ngakhale kuti zimalola kutengera madiresi, malemba, mabokosi ndi zizindikiro, ndipo mukhoza kupanga zolemba zingapo pulojekiti, sindinapeze momwe ndingasungire monga ma templates; Bukuli likuti ndizotheka. Ndikuganiza kuti m'mapulagulu a Grass muli zinthu zabwino zokhuza izi.
