CartoDB, zabwino kupanga mapu Intaneti

CartoDB ndi imodzi mwa mapulogalamu okondweretsa kwambiri opangidwa ndi mapu a intaneti, okongola kwambiri mu nthawi yochepa kwambiri.

Kukonzekera pa PostGIS ndi PostgreSQL, okonzeka kugwiritsira ntchito, ndi chimodzi mwa zabwino kwambiri zomwe ndaziwonapo ... ndipo kuti ndizoyambira pa chiyambi cha ku Puerto Rico, akuwonjezera phindu.

Maofesi Othandizidwa

Chifukwa chakuti chitukuko chimayang'ana pa GIS, chimapitirira kuposa zomwe ndakuwonetserani kale. Zosungidwa Zosakaniza zomwe sizikupezeka pa matebulo.

CartoDB ikuthandiza:

• CSV .TAB: mafayilo olekanitsidwa ndi comma kapena ma tabo
• FP: mafayilo a ESRI, omwe ayenera kupita mu fayilo ya compressed ZIP kuphatikizapo mafayilo a dbf, shp, shx ndi prj
• KML, .KMZ Google Earth
• XLS, .XLSX ya masamba a Excel, omwe amafunikira mitu yoyamba mzere woyamba ndipo ndithudi, tsamba loyamba la bukhulo lidzatumizidwa
• GEOJSON / GeoJSON yomwe ikugwiritsidwa ntchito kwambiri kuti mudziwe deta, kotero ndi yosavuta komanso yothandiza pa intaneti
• GPX, yogwiritsidwa ntchito kwambiri pakusinthana kwa GPS
• OSM, .BZ2, Mapulani Otsegula Mapu
• ODS, OpenDocument spreadsheet
• SQL, izi zimagwirizana ndi kafukufuku wa SQL wojambula wa CartoDB API

Kutsitsa ndikosavuta, muyenera kungowonetsa "onjezani tebulo", ndikuwonetsa komwe kuli. Zatsopano za anyamatawa ndizosangalatsa, chifukwa sikuti deta imatha kuyitanidwa kuchokera ku diski yakumaloko, komanso kuchitidwa pa Dropbox, Google Drive kapena patsamba lomwe lili ndi ulalo wodziwika; kumveketsa kuti sangawerenge pa ntchentche koma adzaitanitsa; koma zimatipulumutsa kuti tizizitsitsa ndikuzikweza.

Amatha kupanga mapu

Ngati ili tebulo chabe, ndizotheka kuwonetsa kuti ndi georeferenced pogwiritsa ntchito gawo kudzera pa geocode monga ndawonetsera kale ndi FusionTables, komanso ngati ili ndi x, y yolumikizana. Itha kusinthidwa georeferenced polumikizana ndi tebulo lina kudzera pazolumikiza kapena kuphatikiza mfundo mkati mwa ma polygoni.

Mbadwo wa zigawo ndizowoneka zokongola, ndi zojambula zowonongeka kale ndi zosavuta kulamulira makulidwe, mtundu ndi chiwonetsero mosavuta.

Ndakhazikitsa mapiri a mizinda ya Honduran ndikuwona momwe mapulaneti okhudzimutsa amavutitsira chidwi kutikumbutsa chifukwa chake maboma amasiye amathandizidwa nthawi zambiri ndi kuwonetsa maboma am'deralo popanda zofuna zachuma.

Ndipo iyi ndi mapu omwewo, oyendetsedwa ndi mphamvu.

Kawirikawiri, zida zowunika ndikuwonetseratu zimakhala zothandiza chifukwa zimalola kupanga zojambulidwa, malemba, nthano, kumagwiritsa ntchito css code komanso mawu a SQL.

Sindizani mawonedwe

Ngati tikufuna kugawana mamapu ndi ena, titha kusintha kuti chosankha chosanjikiza, nthano, bar yosakira ikuwonetsedwa, ngati mpukutu wa mbewa ukuchita ndi zoom, ndi zina zambiri. Kenako kuchepetsa url kapena chikhomo kuti mulowetse kapena ngakhale API code.

Imathandizira mamapu osiyanasiyana akumbuyo, kuphatikiza Google Maps. Komanso ntchito za WMS ndi Mapbox.

Mitengo

CartoDB ili ndi mitengo yotsika mtengo, kuchokera paulere womwe umavomereza mpaka matebulo asanu ndi 5 MB. Njira yotsatira imawononga $ 5 pamwezi ndipo imathandizira mpaka 29MB.

Mtunduwu ukhoza kugwiritsidwa ntchito poyesa masiku 14, koma muyenera kusamala kuti zikuwoneka kuti palibe zotsitsa; kumapeto kwa nthawi ngati dongosololi silinagulidwe, deta imachotsedwa. Ndikuganiza kuti payenera kukhala kuthekera kosunga mtundu waulere ndi zoletsa zamilandu.

Ali ndi kuthekera, tiyenera kuwona momwe ntchitoyi imasinthira. Zachidziwikire kuti ali ndi malingaliro awo pazinthu monga kuchititsa kuchititsa zinthu, kutsitsa magawo omwe sanasungidweko ndi magwiridwe antchito ena a API osinthidwa ndi osagwiritsa ntchito ntchito, kuthana ndi zigawo zoposa 4 pachionetsero, ndi zina zambiri. Pakadali pano chosowa kwambiri ndikufuna kugwiritsa ntchito pulogalamuyo piritsi.

Pomaliza

Ntchito yabwino basi. Ngati zomwe zikuyembekezeka ndikupanga mapu apaintaneti, mosavuta komanso mphamvu.

Kuwongolera kumene timachita lero n'kofulumira, koma pali zambiri zoti muwone.

Ndikukuuzani kuti muyese msonkhano, chifukwa API yanu imapezeka ndipo ndi OpenSource, kotero kwa iwo omwe amadziwa zambiri ... akhoza kugwiritsa ntchito zambiri.
