Kev ntsuam xyuas qhov tseeb ntawm Google nce cov ntaub ntawv - Txaus!

Google lub ntiaj teb muab kev nkag rau koj cov ntaub ntawv nce nrog rau Google qhov siab Google qib API. Civil Site Design, siv sijhawm zoo dua ntawm qhov peev xwm nrog nws cov tshiab Satellite mus rau thaj chaw ua haujlwm. Qhov kev ua no tso cai rau koj xaiv ib cheeb tsam thiab qhov kev ncua deb ntawm cov ntsiab lus ntawm kab sib chaws, nws rov qab los nrog curves ntawm qib nrog Civil Civil Design software thiab lub thaij duab.

Lance Maidlow ntawm ChasmTech LLC teeb tsa rooj plaub no ntawm kev siv uas tau luam tawm nyob rau hauv TwinGEO magazine

Kuv pheej xav txog qhov tseeb ntawm cov ntaub ntawv muab los ntawm Google. Muaj ob qho siv tau cov rooj plaub uas kuv tau xav txog:

  • Conceptual / ua ntej tsim rau cov ntawv tshiab.
  • Nkag mus rau lub topography ntawm lub phiab rau kev ntsuam xyuas dej nyab nrog HEC-RAS 2

Rau kev ntsuam xyuas, Kuv xaiv ob qhov chaw:

  • 1 qhov chaw yog ib qhov khoom loj heev hauv Dunedin, Florida. Rau qhov no, kuv tau muas thaum chiv thawj thiab 2 tsheej lab ntawm cov ntsiab lus ntawm cov ntsiab lus ntawm lub Npe NOAA.
  • 2 qhov chaw yog ib qho kev lag luam tawm tswv yim hauv Lake County, Florida, uas peb muaj kev tshawb xyuas cov ntaub ntawv hauv 100 daim phiaj, nrog rau cov kev tshawb fawb txog cov kev pab tam sim no.

Qhov kev ua satellite mus rau saum npoo, generated qhov chaw rau ob qhov chaw sim hauv tsawg dua 10 feeb txhua. Cov chaw tau los ntawm Google cov ntaub ntawv nce siab kuj ceeb tias thaum muab piv li cov ntaub ntawv soj ntsuam cov ntaub ntawv li ntawm LiDAR thiab cov ntaub ntawv.

Txawm li cas los xij, nws yuav tsis tshua muaj txiaj ntsim heev yog tias Google tau muab lub hauv paus thiab hnub tim ntawm koj cov ntaub ntawv nce siab.

Cov kev tshwm sim zoo sib xws, tab sis yog qhov tseem ntsiab ntawm cov ntsiab lus tseem ceeb ntawm XDiXXX taw piv rau lub hauv paus paub lub pas dej. Qhov kev hloov no tau ntxiv rau LiDAR cov ntaub ntawv hauv Civil Site Tsim ua ntej txoj kev hloov tau, raws li pom hauv qab hauv cov ncauj lus kom ntxaws ntawm cov ntaub ntawv saum npoo ntawm ob qhov chaw. Qhov nruab nrab qhov siab ntawm 8.5 / 1, 2 / 1 thiab 3 / 2 yog qhov zoo sib xws. Qhov siab qhov nruab nrab ntawm qhov hnyav yog 3 taw siab tshaj qhov ntawm cov ntaub ntawv ntawm LiDAR. Qhov sib txawv no yog vim qhov tseeb hais tias cov ntsiab lus yog denser nyob rau hauv cov cheeb tsam qhib piv rau cov cheeb tsam uas them los ntawm cov ntoo. Cov ntaub ntawv satellite tau tsim tawm hauv 3 'kab sib chaws.

Tom ntej no, ib qho kev ntsuam xyuas pom ntawm cov ntaub ntawv qhia txog satellite tau nthuav tawm tias sib piv haum nrog qhov kev mob ntawm cov av.

Nyob rau hauv rooj plaub no, ib qho ntawm yuav tsum tau muab tso rau ntawm qhov nce ntawm Google, saib raws li cov nqaij nyoos thiab qhov dav dav ntawm curves hauv kev sib raug zoo rau cov kev uas twb muaj lawm thiab qhov chaw nyob hauv cov tsev.

Hauv qhov piv txwv nram qab no ntawm cov khoom lag luam, cov kev sib cav tau tsim los ntawm 20 'grid nrog cov ntaub ntawv satellite, cov curves liab tau txais los ntawm cov ntaub ntawv muaj tseeb hauv 100' kab sib chaws.

Cov kev paub hauv zos no, txawm li cas los, tseem ceeb vim tias cov ntaub ntawv nce siab tsis muaj hnub tim paub. Ib qho kev nyuab siab tiav thiab tau npaj tseg tom qab lawv tau sau Google cov ntaub ntawv nce siab. Ib yam li ntawd, ib lub pas dej tuav tau ua nyob rau sab qaum teb ntawm qhov chaw, tom qab tag nrho cov ntaub ntawv nce tau khaws.

Lub Hauv Paus ntawm Google cov ntaub ntawv nce, sib txawv raws koj qhov chaw. Txawm hais tias muaj lus qhia ntxiv txog Google cov ntaub ntawv tshuaj ntsuam tau los ntawm qee qhov chaw, nws tseem tsis tau paub meej.

Txawm hais tias qhov kev tshawb fawb no tsis yog scientific, nws tuaj yeem qhia tau tias Cov Lus Qhia Tshaj Plaws (Google Elevation data) tau txais thiab pom tau rau kev tsim cov qauv kev lag luam los yog tsim kom muaj qhov ntom ntsa, uas siv tau rau kev ntsuam xyuas dej nyab nrog daim ntaub ntawv xws li HEC RAS 2.

  1. Zoo hmo:
    Nws yog qhov nyuab los sib piv cov kev ua siab zoo / meej ntawm cov ntaub ntawv qhia txog qhov tau txais los ntawm ntau qhov chaw.
    Qhov teeb meem yog nyob rau hauv cov txheej txheem xam / cov txheej txheem los ntawm DEM lossis cov ntaub ntawv npog uas tau siv los sib piv tau tau-> ntxaij kauj ruam, Tus qauv Geoidal xav txog, tswj cov ntsiab lus thiab lwm yam.
    Kuv yuav ua qhov kev kawm hauv Spain los sib piv IGN's Lidar z orthometric, RTK GPS daim ntawv ntsuam xyuas tau txhawb los ntawm kev ntsuas qib siab thiab google lub ntiaj teb-> ntawm kuv lub blog kuv yuav qhia qhov twg tawm….http://autodidactaengeomatica.blogspot.com/
    Kev txais tos thiab ua tsaug rau koj txoj kev koom tes ...
