Gisar GIS; Gina da Gyara kayan aiki

Za mu keɓe wannan sakon don ganin kayan aikin da za a gina da kuma gyara bayanai tare da Manifold, a cikin wannan filin Gis na da matukar rauni, yayin da ƙayyade ainihin ƙaddamarwa na kayan aikin CAD tun lokacin da aka adana shi a cikin bayanai yana bukatar cewa ƙayyade "ƙayyadadden" zuwa yawan adadi. A bayyane yake cewa don dalilai masu amfani dalilai biyu kashi goma suna isa ... kuma a wasu lokuta uku.

Amma za ku yi tsammanin kayan aiki da ke da ƙananan mafita don ƙirƙirar da canza tsarin geometries. Bari mu ga abin da yake da shi:

1 Ayyukan halittar

Ana kunna waɗannan ta atomatik lokacin da zaɓin wata ƙungiya, kuma waɗannan sune:

Ya dogara akan halittar abubuwa uku: wurare (polygon), layi da maki; tare da bambancin game da ESRI cewa wani bangaren zai iya ɗaukar nau'o'in abubuwa a duka ƙunshi yanayin Zai iya kasancewa ɗaya daga cikin waɗannan abubuwa uku.

Sa'an nan kuma akwai bambancin halitta da ke tafiya cikin wannan tsari:

  • Shigar da yanki (bisa ga maki), daidai da iyaka na AutocAD ko siffar Microstation
  • Saka yanki kyauta (sanarwa)
  • Saka layi kyauta
  • Saka layi (bisa ga maki)
  • Saka layin da ba a rukuni ba, daidai da layin na AutoCAD da Microstation smartline ba tare da zaɓi don rukuni ba
  • Saka bayanai
  • Saka akwatin
  • Saka akwatin bisa ga cibiyar
  • Saka da'irar
  • Saka da'irar da ke kan cibiyar
  • Saka ellipse
  • Saka ellipse bisa cibiyar
  • Saka da'irar bisa bayanan (cibiyar, rediyo). Wannan karshen yana da matukar amfani a GIS saboda ana amfani dashi da yawa daga ma'auni daga tsinkaye ko matsala ... ko da yake yana da takaice saboda babu wani zabi don tsoma baki a cikin raguwa.

Bugu da ƙari, wannan shi ne shigarwar shigar da bayanai ta hanyar keyboard da na nuna a cikin previous post wanda aka kunna tare da maɓallin "Saka" a kan keyboard.

2 Abubuwan da ake amfani da su.

Wadannan sun kusan isa, kuma daga cikin mafi kyaun suna da zaɓi don zaɓar da yawa a lokaci daya ... bangare da aka iyakance a Microstation. Don kunna ko kashe maɓallin da aka yi (snap) button "sararin samaniya"daga keyboard.

  • Sauƙaƙe zuwa lattice (latitudes da longitudes), idan an kunna lattice, yana ba da damar ɗaukar hoto a matsayin maƙasudin tasiri tsakanin haɗin kai.
  • Koma zuwa grid (xy coordinates), kama da na baya.
  • Cire zuwa polygons
  • Cire zuwa layi
  • Koma zuwa maki
  • Nemi abubuwa, wannan yana daidai da "mafi kusa" na AutoCAD, wanda aka kama kowane maɓalli a gefen polygon ko line.
  • Sauƙaƙe zuwa zabin, wannan shine ɗaya daga cikin mafi kyawun umurni, domin yana ba da dama ga ƙuntatawa kawai akan abubuwan da aka zaɓa, ƙyale haɗuwa da waɗanda suka gabata.

A bayyane yake cewa, "madaidaiciya", "midpoint" da "tsakiya" yana da bukata sosai, tangent ba zata zama dole ba a GIS, kuma ba "ƙila"

  • Yanke (datsa)
  • Sashi abubuwa

Ana buƙatar kayan aiki masu yawa, irin su motsi tare da daidaituwa, a layi daya (azabtarwa) ...

4 Gudanar da zane-zane

Wannan kayan aiki ne na da na yi magana a baya, wanda ya ba da damar yin shiryawa da abubuwar unguwa; kamar haka lokacin da gyaran iyakar iyakokin da ke da makwabta suna karbar wannan gyare-gyare.

Wannan shi ne daya daga cikin manyan ƙuntatawa na sassan ArcView 3x; ArcGIS 9x ya haɗu da wannan ko da yake yana da alama cewa idan kawai ƙunshi yanayin yana cikin ciki Geodatabase, da Bentley Map da Bentley Cadastre.

Akwai kuma bayani da ake kira "masana'antar fasahar" wanda ya ba da damar yin tsaftacewa, tsakanin layin da aka bari, abubuwan da suka haɓaka, sassan layi da kuma zaɓi na warware su da hannu ko kuma aka sarrafa ta atomatik. yana cikin "zane / zane-zane"

A ƙarshe, yayin da Manifold bai ƙara wasu kayan aiki ba, zai zama mafi alhẽri don yin gyare-gyare tare da kayan aikin CAD, kuma ɗauki GIS kawai siffar ko maki don gina a can. A cikin wannan zabi na GvSIG a kokarin ƙoƙarin yin koyi da kayan aiki mafi muhimmanci na gina AutoCAD maimakon ɗaukar cewa sun kasance masu amfani.
