Pengemaskinian pelan gunatanah semasa
Dalam QGIS, modul Difference dan Union dibawah Data Management Tools diperlukan untuk mengemaskini pelan gunatanah semasa. Andainya unjuran peta antara pelan leaut dan pelan gunatanah semasa adalah sama, gabungan adalah mudah. Bagaimana pun, sekiranya apabila lot berkaitan telah dikeluarkan dan ternampak garisan atau silverfish, maka tindakan sewajar perlu diambil untuk "membersihkannya" sebelum mengabungan pelan leaut dengan pelan gunatanah semasa. Mudah saja...kalau tahu bagaimana.
Updating the existing landuse plan
In QGIS, the Difference and Union module are the modules under Data Management Tools required to update the existing landuse plan. On the assumption the map projection between the approved layout plan and the exisitng landuse plan are the same, the merge is simple. However, if upon deleting the affected lot, lines or silverfish appear then masures must be taken to first clean that before merging the approved layout plan with the existing landuse plan. Simple...if you know how.
