Kuzoze kube nini ifayela lokuloba lisinde?

Ngesikhashana ngacabanga ukuthi ifomethi ye-axf yayiyifaka esikhundleni sefayela le-ESRI; kodwa kunalokho ziziphatha njenge-geodatabase ye-ArcPad, okusho ukuthi i-ESRI izomisa ekutheni sihlupheke ngefomethi ye-shp.

Inkinga

Shp format ubuthakathaka iminyaka yayo, ukulondoloza idatha yakho in ifomu tabular njengoba eneminyaka engu-cishe 20 ngaphandle kokuba akwazi ukusungula ubudlelwano futhi zisakaza amafayela amancane ukuthi ukugcina nezakhi ezihlukene kanye nemithetho idatha vector.

ESRI umemezele axf yayo njengendlela format ukusetshenziswa ArcPad ukuthi kusukela 7.1 okufushane Ungasingatha amatafula ezihlobene lapho ungakwazi zihlanganisa izimfanelo, theming, umklamo kanye nezinye izici ukuthi dinorex encane ukuthi wayengeke akwenze.

Nakuba abanye bememeze ezulwini bethi "ingabe sidinga enye ifomethi yedatha yendawo?", i-ESRI igcizelela ukuthi akuyona ifomethi entsha kodwa njenge-geodatabase iwuhlaka lwemithetho yedatha yendawo eyakhelwe ku-Microsoft SQL Server Compact Edition (I-SQLCE) ... ekuphetheni ngokunganaki, i-geodatabase efanayo efanayo abaye bayigxeka ngokuba ne-API enenkani ngokweqile.

... kungahle kungabi yifomethi entsha kepha kunezela ubunzima emakethe yomkhiqizo we-geospatial, wonke umuntu manje kufanele akhe enye inqubo ezosebenzisana nalesi fomethi.

Futhi yikuphi okumele kwenziwe?

• Qoqa amafayela womumo ku-database, izimfanelo zefayela lokuma zigcinwa ku-dbf... ku-BLOB (Into enkulu kanambambili) ezinsikeni eziphansi esitimeleni dbf ... bese uyishaya nge-dbf.
• Khona-ke kwelinye itafula kukhona imethadatha enjengokubheka, ukufanekisa, amafomu kanye nezikripthi.
• Ukuqoqwa kwamafomu okumafomu, nezendlalelo zabo nezinye ukuphelela, kungathathwa njengefayela elilodwa.
• Ungahlanganisa ne-geodatabase, ukwamukela izizinda, ama-subtypes kanye nobudlelwano ... ngicabanga futhi nemithetho ye-topological kanye ne-geoprocessing routines.

Iziphumo

Ekusebenzeni, othile one-GPS angaya ensimini, enze ukulungiswa kwe-cadastral kumephu (hhayi ifomethi elula) njengokuthi basebenza nesikhulumi sabo sedeskithophu, banqume ukuthi ngabe kukhona ubuqiniso bemvelo ngokuhlangana nokuthumela imininingwane nge-gsm ku- imininingwane ephakathi nendawo ... ukuthi awukwazanga ukwenza lokhu? ..., ngiyaxolisa, nge-ArcPad!

Abaningi bakholelwa ukuthi uma i-ESRI iphikelela ekuvikeleni ifomethi yayo ye-dino, ngolunye usuku amafomethi we-xml (kml, gml) azoyidla iphila ... akunandaba uma ushada neMicrosoft.
