A shapefile yog ib qho yooj yim, nontopological hom ntawv khaws cia qhov chaw geometric thiab cov ntaub ntawv qhia txog thaj chaw. Geographic nta hauv a shapefile tuaj yeem sawv cev los ntawm cov ntsiab lus, kab, lossis polygons (chaw). Hauv qab no yog piv txwv li cas shapefiles tshwm hauv ArcCatalog.
Kuj paub, koj ua li cas tsim ib daim ntawv teev npe hauv GIS?
Tsim ib tug tshiab shapefile
- Xaiv ib daim ntawv tais ceev tseg lossis cov ntawv tais ceev tseg hauv cov ntoo Catalog.
- Nyem rau cov ntawv qhia zaub mov, taw tes rau Tshiab, ces nyem Shapefile.
- Nyem rau ntawm lub npe ntawv lub thawv thiab ntaus lub npe rau tus tshiab shapefile.
- Nyem qhov Feature Type drop-down xub thiab nyem hom geometry lub shapefile yuav muaj.
Tsis tas li ntawd, dab tsi yog qhov txawv ntawm ib lub shapefile thiab ib txheej? shp ) yog vector cov ntaub ntawv khaws cia hom rau khaws cia qhov chaw, duab, thiab cov yam ntxwv ntawm thaj chaw. A shapefile yog khaws cia hauv a txheej cov ntaub ntawv ntsig txog thiab muaj ib chav kawm tshwj xeeb. A txheej file (. lyr) yog ib cov ntaub ntawv uas khaws txoj kev mus rau qhov chaw dataset thiab lwm yam txheej khoom, nrog rau cov cim.
Ib yam li ntawd, tib neeg nug, kev siv shapefile yog dab tsi?
Ib Shapefile yog digital vector khaws cia hom ntawv khaws cia geometric qhov chaw thiab cov ntaub ntawv cuam tshuam. Hom ntawv no tsis muaj peev xwm khaws cov ntaub ntawv topological. Hom Shapefile tau qhia los ntawm ESRI rau ArcGIS software.
Cov txheej hauv GIS yog dab tsi?
Txheej yog cov txheej txheem siv los tso saib cov ntaub ntawv thaj chaw hauv ArcMap , ArcGlobe, thiab ArcScene. Txhua txheej xa mus rau ib daim ntawv teev cov ntaub ntawv thiab qhia meej tias cov ntaub ntawv li cas yog portrayed siv cov cim thiab cov ntawv sau. Thaum koj ntxiv ib txheej mus rau ib daim ntawv qhia, koj qhia nws cov dataset thiab teem nws daim ntawv qhia cov cim thiab labeling zog.

Rasters yog cov duab dav hlau digital, duab los ntawm satellites, cov duab digital, lossis txawm tias scanned maps
