Kodi mawonekedwewa adzapitirira liti?

Kwa kanthawi ndinaganiza kuti fomu ya axf inali m'malo mwa fomu ya ESRI; koma makamaka zimakhala ngati geodatabase kwa ArcPad, zomwe zikutanthauza kuti ESRI idzaumiriza kutipweteka ndi machitidwe a shp.

Vuto

Zofooka za mawonekedwe a shp ndizokalekeza, powasunga deta yake momwe anachitira pafupifupi zaka 20 zapitazo osakhoza kukhazikitsa maubwenzi komanso kupezeka kwa maofesi ang'onoang'ono omwe amasungira makhalidwe ndi malamulo a vector.

ESRI adalengeza Mzere wake ngati mtundu wa Arcpad amagwiritsira ntchito izo kuchokera mu 7.1 version akhoza kuthana ndi matebulo okhudzana kumene mungakhale nawo zikhumbo, kutsitsa, maonekedwe ndi zinthu zina zomwe dinorex yaying'ono sangachite.

Ngakhale ena adafuula kumwamba kuti "kodi tikufuna mtundu wina wa data wapamalo?", ESRI imaumirira kuti si mtundu watsopano koma monga geodatabase ndi dongosolo la malamulo a malo opangidwa pa Microsoft SQL Server Compact Edition (SQLCE) ... mosaganizira kanthu, mofanana geodatabase omwe ambiri adatsutsa chifukwa chokhala ndi API osakanikirana.

... sungakhale mtundu watsopano koma umaphatikizapo zovuta kumsika wamagetsi, aliyense ayenera tsopano kupanga pulogalamu yotsatizana ndi mtundu uwu.

Ndipo kodi akuyenera kuchita chiyani?

• Sungani mawonekedwe a mawonekedwe mu database, zizindikiro za mawonekedwe a mawonekedwe akusungidwa mu dbf... mu BLOB (chinthu chachikulu cha Binary) mu ndondomeko yazithunzi ya dbf ... ndikugunda ndi dbf.

• Kusonkhanitsa mawonekedwe, ndi zigawo zawo ndi zina zonse, kungathe kuonedwa ngati fayilo limodzi.
• Mungathe kuphatikizanso ndi geodatabase, kuvomereza madera, maumboni ndi maubwenzi ... Ndikuganiza kuti malamulo a topological ndi machitidwe a geoprocessing.

Zotsatira

Mwachizoloŵezi, wina yemwe ali ndi GPS akhoza kupita kumunda, akonze kayendedwe ka cadastral pamapu (osati zosavuta mawonekedwe) ngati kuti akugwira ntchito ndi mawonekedwe awo apakompyuta, kudziwa ngati pali topological umphumphu pakupaka ndi kutumiza deta kudzera gsm kuti central database ... simungathe kuchita izi? ... pepani, ndi ArcPad!
