JPBD planning colour template


Templat warna perancang JPBD

Berbeza dengan proprietari GIS, QGIS mempunyai kelebihan untuk mengaktifkan fail .tab dan .shp secara serentak. Perkara ini tidak boleh dilakukan oleh GIS berlesen, kemungkinan besar, kerana jenama tersebut berhasrat pengguna akan mengutamakan format GISnya. Keadaan ni memaksa pengguna convert fail mengikut format perisian yang dipasang. QGIS pula tak banyak soal: kiri makan, kanan pun makan, cuma format de facto QGIS adalah .shp. Ini kemungkinan besar adalah kerana .shp merupakan format utama dikalangan pengguna sedunia. Dalam hal ni, walaupun fail .tab dapat diaktifkan bersama fail .shp dan boleh diguna untuk membuat SQL query, kerja menyunting hanya dapat dilakukan dalam fail .shp. Small problem! Oleh kerana paparan fail gunatanah dalam QGIS mengikut warna default dan tidak mengikut warna kod gunatanah JPBD, satu percubaan dibuat oleh Fadzlan untuk mewujudkan style atau templat QGIS yang dapat menggantikan warna default mengikut Kod Warna Kelasifikasi Gunatanah JPBD. Prototaip ni berjaya dan seterusnya dimantapkan lagi oleh saya berpandukan Manual GIS JPBD bagi rancangan pemajuan dan kini diguna secara harian oleh kami. Kalau berminat, fail .qml tersebut boleh dimuat turun disini. Ia diberi nama "v1plgcolor1.qml" kerana adalah berasaskan Manual GIS JPBD masakini iaitu Versi 1. Jika Manual GIS JPBD dikemaskini ke Versi 2, tindakan selanjutnya akan dibuat untuk menghasilkan "v2plgcolour1.qml".

JPBD planning colour template

As against proprietary GIS, QGIS excels in simultaneously activating .tab and .shp files. This is not possible in proprietary GIS, most likely, because the marque brands hopes that users will give in to their GIS format. This requires users to convert files according to the format of the software used. QGIS does not ask much questions: no left, no right, just that the QGIS  de facto format is .shp. This most probably is because .shp has been the principal format among GIS users internationally. In this matter, although .tab files can be SQL queried, editing is only possible in .shp. Small problem! Since viewing in QGIS is based on a default colour and not JPBD planning colours, a trial was carried out by Fadzlan to create a style or QGIS template that could replace the default colour according to the JPBD landuse colour classifications. This prototype was successfully developed and improved by myself based on the JPBD GIS Manual for development plans and is currently used daily by me. If interested, the .qml file can be downloaded here. If the JPBD GIS Manual is upgraded to Ver. 2, the appropriate action will be done to produce a "v2plgcolor1.qml".
