Kada ka yi abin da suka yi tare da CAD shirye-shirye GIS
en el previous post, mun dauki wani lokaci muna bayanin yadda ake kirkirar grid zane, ta hanyar daidaitawa a Excel, wanda aka wuce zuwa UTM kuma daga bisani ya shiga cikin fayil na AutoCAD.
Sannan a mataki na biyu mun ga yadda aka aika wannan fayil ɗin zuwa aikace-aikacen GIS don ƙirƙirar yanayin yanki tsakanin tsinkaya.
Lokacin da nake karatun Calculus I, wani malamin Asalin Asturian ya gaya mana cewa akwai hanyoyi guda biyu don kirga ƙungiyar shanu: kirga su ko sauka zuwa matakin ciyawa, kirga ƙafafu da rarrabawa su huɗu, kuma idan babu ainihin bayanan da ke fitowa truncating zuwa ga mafi kusan duka .
Da kyau, bari mu gani a matakai guda uku yadda ake yin duk abin da muka cimma a waɗancan lokuta na baya, tare da aikace-aikacen GIS. A halin da nake ciki zan yi shi da da yawa, amma ina tsammanin dole ne a yi tare da wasu aikace-aikacen da suka fi tsada.
1. Createirƙiri sabon fayil
Don ƙirƙirar sabon fayil kuna yin "file / sabo"
Don ƙirƙirar sabon Layer "fayil / crate / zane" ko tare da sarrafawar yadudduka
Sannan muna sanya mata tsinkaye, danna dama akan layin da aka ƙirƙira, kamar yadda muka bayyana a post ɗin baya. Zan yi amfani da UTM Zone 16 Arewa, WGS84
2 Tabbatar da grid
Don saita layin wutar, yi "view / graticule", idan kana son laiton da laiton raga. Idan kana son layin UTM zai zama "ra'ayi / grid"
Kamar yadda nake so shi ne yankin UTM 16, arewa, na zabi tsawon -90 zuwa -84, kuma tun da ina ba na son ɓangaren cikin gida na zaɓar wuri na digiri na 6.
Dangane da sararin samaniya, Ina sha'awar latitude 0 zuwa 72, kuma ina raba shi kowane digiri 8. Sannan zaku iya zaɓar idan kuna son layuka masu ƙarfi ko siffofi ko kawai gicciye ne a mahadar. Ta hanyar yin Ok, Na riga na sami grid, wannan kawai yana cikin yanayin kallo.
3. Createirƙiri grid.
Latsa maɓallin "ƙirƙiri", da kuma voila.
Halayen: kada kuyi da CAD abin da za a iya yi tare da GIS.
Shin kana son sanya shi ya zama mai yawa? zaɓi daga inda zuwa wane, ƙarfin kuma latsa maɓallin ƙirƙirar ... dole ne a gane cewa shirye-shiryen GIS suna iyakance dangane da ƙirar bayanan vector, amma dangane da ƙirƙirar tsauraran matakan zane suna da kyau.
... kwatsam, ta yaya ake yin wannan tare da samfuran AutoDesk ko ESRI?
