Tsim kab contour nrog ArcGIS

Nqa daim ntawv soj ntsuam cadastral nrog qhov chaw nres tsheb tag nrho, sib nrug los ntawm qhov muaj millimeter precision, kuj tuaj yeem siv rau lwm cov laj thawj, vim peb muaj qhov nce ntawm txhua qhov taw tes. Cia peb pom nyob rau hauv cov ntaub ntawv no, yuav ua li cas tsim cov kab contour, uas peb twb pom nrog AutoDesk 3Dnrog Bentley Geopak y manifold GIS, yog li ntawd rau kev kawm ntawv, qhov no peb yuav ua nrog ArcGIS.

1. Cov ntaub ntawv CAD

Rau qhov qoj ib ce no, Kuv muaj cov ntaub ntawv tshuaj ntsuam xyuas hauv dgn, ib qho rau ib hnub ua haujlwm. Nws yuav yooj yim li:

• Arctoolbox
• Cov ntaub ntawv sib koom tes
• Kev ceev ceev

Cov ntaub ntawv dgn raug xaiv, thiab voila, hauv txhua qhov ntawm lawv. Saib seb lawv saib zoo nkauj npaum li cas, koj tuaj yeem pom hnub uas cov tub ua haujlwm tau ua haujlwm, thaum lawv ua dag zog thiab thaum twg lawv cheered.

Ntau tshaj li nthuav, koj tuaj yeem pom qhov twg lawv coj cov ntsiab lus, qhov no yuav luag tsuas yog hauv cov kev taw qhia cov kev hloov ntawm cov blocks, txhawm rau coj sab nrauv thiab hauv qab nrog ntsuas kab xev. Siv cov txheej txheem los txhawb txoj kev sojntsuam rau lub sijhawm tsis sib xws nrog cov ntawv sau lossis lwm yam kev ntsuas. Koj tseem tuaj yeem pom qhov twg lawv tau nruab cov khoom siv kom saib rov qab.

2. Ntaus cov ntsiab lus rau hauv geodatabase

Txog kev coj kom zoo, Kuv yuav sau cov ntsiab lus mus rau thaj chaw. Txhawm rau ua qhov no, peb xav tias nws tau tsim nrog ArcCatalog thiab txhais qhov tshwj xeeb chav kawm.

• ArcToolbox
• Cov cuab yeej hloov tshiab
• Mus rau geodatabase
• Feature hoob kawm rau geodatabase

3. Tsim cov qauv

Qee qhov ntawm cov kauj ruam no yuav tsum tau saib, tab sis rau lub hom phiaj ntawm kev nkag siab txog kev siv 3D Analyst, peb yuav saib lawv hauv qhov kev txiav txim no.

• ArcToolbox
• 3D Analyst cov cuab yeej
• Struts
• Tsim kev struts

Nrog rau qhov no peb tsuas tau sau lub npe ntawm tus qauv, peb yuav sau cov ntsiab lus:

• Ntxiv feature hoob kawm rau struts
• Tsim kev struts

Tam sim no peb yuav ua kom muaj tus TIN

• ArcTool lub thawv
• 3D Analyst cov cuab yeej
• TIN creation
• Tsim TIN

Koj tuaj yeem pom tau tias nyob rau ntawm qhov xaus uas tsis muaj cov ntsiab lus txaus qhov kev sib tw nyob rau sab nrauv, tab sis nyob qhov twg ntawm txoj kev yog, seem nyob.

Kuv tseem tuaj yeem pom tias vim tias lawv tsis tau lees paub, hauv no nqa cov tub hluas yuam kev los ntawm kev tsis khaws lub tshuab nqa hauv kev hloov ntawm lub tshuab nqus. Txuag tau qhov yuam kev, los ntawm kev txhais cov ntsiab lus nyob ze, tab sis kev saib xyuas tuaj yeem muaj sijhawm nyob rau kom kho qhov tseeb. Tsis tas li ntawd hais tias nyob hauv thawj ob lub chaw georeference lawv siv qhov nce kev sib koom tes tau muab los ntawm GPS thiab qhov kev ncua deb txaus kom txo tau qhov kev sib hloov hloov vim qhov tsis raug ntawm GPS.

4. Tsim kab contour

Txhua zaus hauv 3D Analyst

• TIN Ntws
• TIN Contour

Ntawm no peb xaiv qhov tshiab tsim TIN, lub phiaj txheej thiab lub caij nruab nrab ntawm qhov kev sib tham (ntawm lwm tus Pirouettes uas tau cawm kuv vim li cas ntawm qhov chaw).

Cov kauj ruam yog ntau dua thaum piv rau Manifold GIS, tab sis cov kev xaiv muaj zog dua.

5. Tsim kom muaj txoj kab nqes qhia.

• TIN deg
• TIN cuam tshuam

Dab tsi yog tuaj yog siv qhov no, uas tuaj yeem siv rau cov tsim dej ntws, raws li qhov no tsis tsuas yog kev tshawb fawb txog av, tab sis kev tshawb fawb saum toj kawg nkaus nrog uas koj tuaj yeem ua haujlwm txoj kev profiles nrog ob peb kauj ruam .
