Adalah satu umat nie, dia suruh saya masukkan peta tanah dia kedalam computer menggunakan autoCAD, tapi saya tak reti nak baca map tersebut, ada sesiapa boleh bantu caner nak baca drawing nie?

peta tanah? Certified Plan (CP) ke? . Kalu CP ko bly masuk guna bearing/jarak. Start kat titik (tanda sempadan) yg ada koordinat. Utk CP, biasanya guna projection Cassini-Soldner so, bleh kata lot tanah tu terletak atas flat surface (X,Y plane)

Hehe tak tahu plak CP ke tak, orang kat sini panggil map nie RSO. Esok I snap gambar dia dan masukkan kat sini.....

RSO tu sebenarnya ada unjuran peta (map projection). RSO = Rectified Skew Orthomorphic. Parameter unjuran berbeza bagi semenanjung (MRSO) dan Sabah/ Sarawak (BRSO) sbb reference system berbeza.

Tapi biasanya bagi peta menunjukkan lot tanah (CP), unjuran yg digunakan adalah State Cassini (Parameter berbeza bagi setiap negeri).

Mana2 unjuran pun masih consider atas plane surface  sbb tujuan utama unjuran supaya geographic location buleh dipetakan di atas satah (kertas)

Semakin pening aku baca explanation you nie mukekekeke

Aku musykil yg amat sangat bukan apa, caner dia calculate bearing nie.....

Dah sah aku ni x bley jadik cikgu :lol

Biasanya dalam CP, bearing is not calculated, but measured  (legal constraint). Tapi kalu nak kira bearing dari koordinat, guna formula tangent yg biasa:

kalu ada koordinat 2 titik, katakan (X1,Y1)  dan (X2,Y2)
tan ? = (X2-X1)/(Y2-Y1)

jadi, sudut ? = inv tangent [(X2-X1)/(Y2-Y1)]

Tapi harus di ingat, bearing dikira dari arah utara (nilai 0

attee, wehh!!!

kalau peta tu tak besor sgt, buleh leee mike 'scan' lepas tu 'digitize'kan.

kalau besor sgt eloklee gunakan digitizer template. isyyy!!! udoh lama bebenor tak teman ngajor menda ni sampai udoh lupa...

hehehe.......

Selalunya bearing nie kita kira dari North kan? TU yg aku pening kepala tengok map nie, let say V line kat bawah nie:


           \           /
            \         /
             \       /
              \     /
               \   /
              A\|/B
                C

Let say line | (C) tu north ek,  Kat line A tu dia tulis 325

Menatang apa itu digitizer template? Den nie bukan professional dalam bidang nie, cuma ada basic knowledge dalam technical drawing.....

Rasanya Tablet DIgitizer nih. Alaa.. digitizer yg ada papan dia tuuu..Kertas peta tu kita lekatkan kat atas tablet pastu register control points. Pastu boleh digitize.

Kalu Yeepi nak scan sikit2 pun boleh kalau peta tu besar. Lepas register control points nnt bercantum balikla peta tu

Eh.. Dulu Lis pun ada belajar ni. Tp cemana pulak line B boleh bearing dia kurang dari line A? Sepatutnya kalu C tu north, line B tu mesti dalam lingkungan 0

Dah selesai dah masalah I, rupa rupanya I kena ikut susunan batu sempadan tanah dan mesti start from batu utama untuk start melukis kekekeke

10 Ribu? Alahai, project I nilai ratus ratus ringgit jer, tak berbaloi nak beli
