CartoDB, qhov zoo tshaj plaws los tsim maps online

CartoDB yog ib qhov kev nthuav dav tshaj plaws uas tsim rau tsim cov qauv hauv online, muaj yeeb yuj hauv lub sijhawm luv luv.

Mounted on PostGIS thiab PostgreSQL, npaj siv, yog ib qhov zoo tshaj plaws uas kuv tau pom ... thiab tias nws yog ib qho pib ntawm Hispanic keeb kwm, ntxiv tus nqi.

Cov Qauv Txhawb Nqa

Vim tias nws yog ib txoj kev loj hlob rau GIS, nws mus ntau dhau qhov kuv tau qhia koj ua ntej. FusionTables uas yog raws li cov ntxhuav xwb.

CartoDB txhawb kev:

• CSV .TAB: cov ntaub ntawv sib cais los ntawm cov ntawv nyeem lossis tabs
• SHP: ESRI ntaub ntawv, uas yuav tsum mus hauv compressed ZIP ntaub ntawv nrog rau cov ntaub ntawv dbf, SHP, shx thiab prj
• KML, .KMZ ntawm Google ntiaj teb
• XLS, .XLSX ntawm cov ntawv xijpeem, uas yuav tsum tau hau kev rau thawj kab thiab ntawm chav kawm, tsuas yog thawj nplooj ntawm phau ntawv yuav raug xa los
• GEOJSON / GeoJSON uas yog siv rau cov ntaub ntawv sib txawv, yog li lub teeb thiab ua haujlwm rau lub vas sab
• GPX, dav siv rau GPS cov ntaub ntawv pauv
• OSM, .BZ2, Kev Tshaj Lawm Txoj Kev Qhib Qhib
• ODS, OpenDocument spreadsheet
• SQL, qhov no yog sib npaug ntawm cov kev sim SQL cov lus hais ntawm CartoDB API

Lub upload yog yooj yim, koj tsuas yog yuav tsum qhia "ntxiv lub rooj", thiab qhia qhov twg nws yog. Kev tsim kho tshiab ntawm cov neeg no yog qhov nthuav, vim tsis yog tsuas yog tuaj yeem hu cov ntaub ntawv los ntawm cov disk hauv zos, tab sis kuj tau tuav ntawm Dropbox, Google Drive lossis ntawm ib lub xaib nrog lub npe url; qhia meej tias nws yuav tsis nyeem nws ntawm ya tab sis yuav import nws; tab sis nws cawm peb yuav tsum txo nws thiab tsa nws.

Muaj peev xwm tsim cov duab

Yog tias nws tsuas yog lub rooj, nws yog qhov ua tau los qhia tias nws yog georeferenced los ntawm txhais tau tias ntawm ib kem ntawm geocode raws li kuv tau pom ua ntej nrog FusionTables, tab sis kuj yog tias nws muaj x, y kev sib koom tes. Nws tuaj yeem ua tau georeferenced los ntawm kev sib koom ua ke nrog lwm lub rooj sib txuas los ntawm cov kab ntawv sib txuas lossis los ntawm kev suav cov ntsiab lus hauv ntau.

Cov cim ntawm cov khaubncaws sab nraud povtseg yog qhov kev ua yeebyam ua ntej, thiab muaj kev tswjhwm ua kom pom tau yooj yim, cov xim thiab cov ntawv pov thawj yooj yim heev.

Kuv tau tsa cov txheej txheem ntawm Honduran, thiab saib pom li cas yog daim ntawv qhia kev ceev ntwm uas ua rau peb nco qab tias vim li cas cov txom nyem cov menyuam tuaj yeem txuam nrog feem ntau ntawm cov kev txwv ntawm tsoom fwv hauv zos tsis muaj kev tswj hwm ntawm cov nyiaj txiag.

Thiab qhov no yog tib daim ntawv qhia, kev ua zoo siv.

Feem ntau, cov cuab yeej rau kev tsom xam thiab kev pom tau yog cov tswv yim vim tias lawv tso cai rau tsim cov ntxaij lim dej, cov ntawv, cov lus dab neeg, kev siv cov css code thiab cov lus tseem ceeb ntawm SQL.

Tshawb nrhiav pom

Yog tias peb xav qhia cov duab qhia chaw rau lwm tus, peb tuaj yeem tsim kho qhov txheej xaiv, cov lus dab neeg, tshawb xyuas kab qhia pom, yog tias nas kos yuav ua nrog qhov zoom, thiab lwm yam. Tom qab ntawv tus luv dua url los yog cov cai rau embed los yog txawm API code.

Nws txhawb ntau hom duab qhia yav dhau los, suav nrog Google Maps. Tsis tas li WMS thiab Mapbox cov kev pabcuam.

nqi

CartoDB muaj cov txheej txheem tsim kev nplua tus nqi, los ntawm cov ntawv pub dawb uas lees paub txog 5 rooj thiab 5 MB. Cov kev xaiv tom ntej no raug nqi $ 29 tauj ib hlis thiab txhawb nqa txog 50MB.

Cov ntawv no tuaj yeem siv hauv kev sim hauv 14 hnub, tab sis koj yuav tsum ceev faj tias thaj tsis muaj qhov txo qis; Thaum kawg ntawm lub sijhawm yog tias txoj kev npaj tsis tau yuav, cov ntaub ntawv yuav lwv. Kuv xav tias yuav tsum muaj txoj hauv kev kom muaj qhov hloov dawb nrog rau kev txwv ntawm rooj plaub.

Lawv muaj lub peev xwm, peb yuav tsum pom cov kev pabcuam hloov li cas. Muaj tseeb lawv muaj lawv cov phiaj xwm hauv kev ua haujlwm xws li hosting efficiency, loading cov txheej txheem tsis-tuav thiab ntau cov haujlwm API tau hloov kho rau cov neeg siv khoom tshwj xeeb, tuav ntau dua 4 txheej ib cov zaub, thiab lwm yam. Txog rau tam sim no qhov tsis txaus ntseeg tshaj plaws yog xav siv daim ntawv thov los ntawm ib ntsiav tshuaj.

Nyob rau hauv xaus

Tsuas yog cov kev pabcuam zoo. Yog tias dab tsi xav kom ua tiav yog tsim cov phiaj xwm online, nrog kev yooj yim thiab lub zog.

Kev ntsuam xyuas peb niaj hnub no yog qhov ceev, tab sis muaj ntau yam ntxiv.

Kuv xav kom koj sim cov kev pabcuam, vim koj qhov API muaj thiab Nws yog OpenSource, rau cov neeg uas paub ntau tshaj ... lawv tuaj yeem siv ntau dua.
