CartoDB, zabwino kupanga mapu Intaneti

CartoDB ndi imodzi mwa mapulogalamu ochititsa chidwi kwambiri opangidwa ndi mapu a intaneti, akuwonetsa nthawi yayifupi kwambiri.

cartodKukonzekera pa PostGIS ndi PostgreSQL, okonzeka kugwiritsira ntchito, ndi chimodzi mwa zabwino kwambiri zomwe ndaziwonapo ... ndipo icho ndi chiyambi cha chiyambi cha ku Spain, kuwonjezera phindu.

Maofesi Othandizidwa

Monga chitukuko choyang'ana pa GIS, icho chimapitirira mochuluka kuposa zomwe ine ndasonyeza 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
  • Ma XLS, .XLSX Excel sheets, omwe amafuna kuti mitu yoyamba ikhale yoyera, pepala loyamba la bukhulo lidzatumizidwa
  • GEOJSON / GeoJSON yomwe ikugwiritsidwa ntchito kwambiri pa deta yamkati, kotero ndi yosavuta komanso yothandiza pa intaneti
  • GPX, yogwiritsidwa ntchito kwambiri kwa kusintha kwa deta ya GPS
  • OSM, .BZ2, Mapulani Otsegula Mapu
  • ODS, OpenDocument spreadsheet
  • SQL, izi zimagwirizana ndi kafukufuku wa SQL wojambula wa CartoDB API

Kutsetsako ndikosavuta, ingowonetsani "kuwonjezera tebulo", ndikuwonetsa komwe kuli. Zomwe amapanga anyamata awa ndizosangalatsa, chifukwa si deta yokha yomwe ingatchulidwe kuchokera ku disk yakudziko, koma yokhala ndi Dropbox, Google Drayiti kapena tsamba lomwe lili ndi URL yodziwika; Fotokozerani kuti sadzawerengapo ntchentche koma adzaitanitsa; koma chimatipulumutsa kuti tichotse ndikutsegula.

Amatha kupanga mapu

Ngati tebulo chimodzi chokha zingasonyeze kuti georeferencie kudzera mzati kudzera geocode monga anasonyeza pamwamba ndi Fusiontables, komanso ngati ali ndi ndondomeko ×, Y. Mungathe ngakhale kugwiritsidwa ntchito pogwirizanitsa ndi tebulo lina pogwiritsa ntchito zipilala zogwirizana kapena kuika mfundo mkati mwa polygoni.

Mbadwo wa zigawo ndi wodabwitsa, ndi zowonongeka zojambula ndi malo kuti athetse kulemera kwake, mtundu ndi kuwonetseredwa mosavuta.

Ine ndakweza wosanjikiza a m'midzi Honduras, ndi kuwona mapu chidwi kachulukidwe mokweza zikutikumbutsa chifukwa malamba umphawi imakhudzana nthawi zambiri ndi massification wa maboma a m'mayikowo popanda muyezo wa kudziyimira pawokha ndalama.

makapu am'mapu am'mapu postgis

Ndipo iyi ndi mapu omwewo, oyendetsedwa ndi mphamvu.

mapu postgis

Kawirikawiri zida zowunika ndi kuziwonetsera zimakhala zothandiza kwambiri ngati zimalola kupanga zojambulidwa, malemba, nthano, kugwiritsa ntchito makina a css komanso mawu a SQL.

Sindizani mawonedwe

Ngati tikufuna kugawira mapu ndi ena, tikhoza kukonza kuti tiwonetse wosankha wosanjikiza, nthano, bar yokufufuzira, ngati mpukutu wa mbewa udzachita ndi zojambula, ndi zina. Ndiye a kuchepetsa url kapena khodi kuti mulowetse kapena ngakhale API code.

Ikuthandizira mapu osiyanasiyana osiyanasiyana, kuphatikizapo Google Maps. Ndiponso ma WMS ndi Mapbox services.

Mitengo

CartoDB ili ndi machitidwe osasinthika, kuchokera ku maulere omwe amavomereza ku matebulo a 5 ndi 5 MB. Chotsatira chotsatira chimadola madola a 29 pamwezi ndipo chimathandizira mpaka 50 MB.

Tsamba ili lingagwiritsidwe ntchito pamayesero kwa masiku 14, koma muyenera kusamala kuti palibenso downgrade; kumapeto kwa nthawi ngati dongosolo silinapezeke, deta imachotsedwa. Ndikuganiza kuti payenera kukhalapo mwayi wosunga maulendo aulere ndi zoletsedwa.

mapu a intaneti

Iwo ali ndi mwayi, muyenera kuwona momwe ntchito ikusinthira. mapulani Insurance ndi dzuwa zawo m'madera monga nyumba, zigawo katundu ndi ndinkakhala nalo API magwiridwe ndinazolowera ogwiritsa chizolowezi, wolunjika kuposa 4 zigawo chifukwa anaonetsa, etc. Pakali pano osowa kwambiri akufuna kugwiritsa ntchito pulogalamuyi.

Pomaliza

Ntchito yaikulu basi. Ngati mukuyembekeza kupanga mapu pa intaneti, mosavuta ndi mphamvu.

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

Ndikulangiza kuti muyese utumiki, monga API yake ikupezeka ndipo ndi OpenSource, kotero kwa iwo omwe amadziwa zambiri ... akhoza kugwiritsa ntchito zambiri.

Pitani ku CartoDB

Yankho la 2 kwa "CartoDB, yabwino kwambiri popanga mapu a intaneti"

  1. Tithokoze chifukwa cha malongosoledwewo. Uthengawu ukunena kuti ngati nthawi yoyesa yatha, deta yonse ichotsedwa. Kodi pali nthawi yoti tisankhe matebulo oti tisiye akugwira ntchito pamayesero awo?

  2. Ndemanga, ngati n'kotheka kuchepetsa pamene mukuyesedwa magellan :). Chinthu chachikulu!
