Maƙala; topology da tsarin tsarin

Ina samun wata buƙata daga wani wanda ya karanci ilimin kimiyyar lissafi a ciki Argentina da UTEM na Chile da farfesa ya tura aiki akan Manifold; don haka na yi amfani da damar don yin post game da shi.

1 Shin Manifold yana tallafawa topology?

Ee, don yin wannan dole ne a kunna zaɓin hanyar da aka raba "gyara / shiryawa rabawa"

Ta wannan hanyar, abun ciki na vector wanda ke raba nodes a cikin ƙayyadaddun zai iya yin haɗin ƙauyen su. Aiwatar da duka biyu don zargi da kuma gyara abubuwa da hannu.

Don ayyana ƙayyadaddun, danna maɓallin dama a kan Layer, zaɓi kaddarorin kuma a can za ku iya tantance madaidaicin yanayin da ya shafi duka tsinkaye da ƙididdigar sararin samaniya, tsabtace yanayin ɗabi'a da "editan rabawa".

A misalin da nake nunawa, idan ina da waɗannan abubuwan, ko da suna masu zaman kansu ne, lokacin motsi, duk abubuwan da suka haɗu kuma waɗanda ke cikin ainihin zaɓaɓɓen wannan rukunin, za su motsa.

Idan abin da aka gama ba ayi aiki da shi ba, da an sami sakamako:

Daidai ne ga polygons, maki da sarƙoƙi na layi; Hanyar Manifold tana goyan bayan faranti da ke da waɗannan nau'ikan abubuwa guda uku ba tare da buƙatar su raba da keɓaɓɓun yadudduka ba.

Hakanan yana da ban sha'awa mu fahimci cewa alkaluman na iya kasancewa cikin yadudduka daban-daban, muddin aka nuna su akan taswira; saboda wannan, zaku iya samun takaddun tsari tare da iyakokin makirce-makirce, a cikin hanyar Lines yayin da wani Layer yana da polygons. Ko da a ƙarshen za'a iya samun nodes a cikin hanyar maki ... Na sani, hauka ce wacce ba ta wanzu a cikin tsohuwar ƙwayar cuta amma yawanci tana faruwa ne a cikin tsarin ruwa inda akwai bawuna da rijiyoyi. Gyara nono yana canza abubuwa daban-daban waɗanda suka zo daidai a wannan lokacin, matuƙar suna da aiki a cikin ɗayan kallo (taswira).

Wannan shi ne babban rauni na nau'ikan 3x na ArcView; GvSIG yana goyan bayan sarrafa topological, kuma Bentley ya aiwatar da shi a cikin aikace-aikace don cadastre da ake kira "Bentley Cadaster"

3 Samfurin samfurin GIS da yawa?

Walƙiya, wannan tambaya ta fi rikitarwa kuma ban sami abubuwa da yawa ba a rukunin gidan yanar gizo na Manifold.

Anan akwai hanyar haɗi ga samfurin abu, ban sani ba idan akwai wani abu kuma ba na jin a cikin matsayi na amsa wannan tambaya ko dai ... amma a nan ana iya samun wani abu dabam.
