Latihan: Latihan QGIS, ILKPKT, Bukit Tinggi, 29-30.8.2012

17 peserta menghadiri sesi latihan QGIS terahkir di ILKPKT bagi tahun 2012 dan datang dari  beberapa pihak berkuasa perancang tempatan, badan berkanun dan Jabatan Perancang Bandar dan Desa Negeri. Ini boleh dikatakan OK memandangkan ianya baru selepas cuti raya. Kali ini latihan diadakan di seksyen baru yang telah direkabentukkan khas untuk latihan. Pihak Urusetia pula membawa peserta-peserta melawat Colmar Tropicale pada waktu malam pertama. Setalah pulang ke ILKPKT, beberapa peserta mengambil peluang menggunakan kemudahan gym sehingga ke jauh malam malahana ada yang hanya sedar lewat pada hari kedua bahawa terdapat bilik Karaoke paras pertama. Penyediaan makan didapati ringkas tetapi lazat. Di ucapan penutup, saya memberitahu  bahawa tidak pasti sama ada kursus ini akan dilanjutkan pada tahun hadapan kerana ada hamba Allah yang tidak senang melihat saya melaungkan masa melatih orang dalam QGIS luar pejabat. Saya rasa perkara ini hanya boleh diatasi dengan pencampuran tangan dari pihak Kementerian. 

Training: QGIS training, ILKPKT, Bukit Tinggi, 29-30.8.2012

17 participants attended the last training session at ILKPKT for 2012 who came from various local planning authorities, regional authorities and state planning departments. Is is not too bad considering it is just after the festive season. Training this time was held at a new wing specially designed for training. The Secretariat later treated the participants that night to a tour of Colmar Tropicale located in the neighbourhood. Later some participants took to the gym till the middle of the night. Some found out a little too late (time to leave) that a Karaoke room was located at the ground floor. Food was simple but  delicious. At the closing speech, I said that I do not know whether there will be any QGIS training course next year as someone is not keen on the idea of me spending time offering my services here. I would expect only Ministerial intervention can circumvent this.

QGIS amat senang untuk difahamai bagi golongan yang tak mempunyai pengetahuan mengenai bidang GIS. Diharap kursus ini dpata diperluaskan bagi mendalami lagi QGIS ini.

Mohd. Khairul Anuar Abdullah, JPBD Negeri Pahang

QGIS patut dipelajari dan digunakan pada masa akan datang. Software ini jika dipelajari dengan lebih mendalam, amat mudah berbanding MapInfo atau software GIS yang lain. Yang paling penting, software ini percuma. Masa dapat dijimatkan dengan penggunaan software ini. Ia juga patut dipelajari bukan saja Unit GIS malah unit-unit yang berkaitan.

Ali Mohd Noor, MP Klang

Lebih baik daripada MapInfo walau bagaimanapun terpulang kepada Ketua Jabatan.

Nurul Hashima Haironi MP Kajang

QGIS adalah software yang mudah difahamai dan dipelajari kerana sepanjang 2 hari mempelajarinya, ia tidak susah seperti yang disangka. Walau bagaimana pun, ia perlu didedahkan kepada semua staf supaya ia dapat diselaraskan dengan semua Jabatan/agensi. Ia juga memudahkan kerja editing data dan analisis data.

Mustafa Alias, MP Ipoh

Kursus yang menarik, perlu ditambah kursus bagi memantapkan lagi kemahiran untuk menggunakanya. Tambahan masa kurus untuk kelas advance. 

Norazmi Shah M. Redzun, MP Ipoh

Terima kasih

Suriyatun Zaidun, MP Ipoh

QGIS bagus sekali dipelajari untuk memudahkan tugasan dipejabat. Perlu diteruskan dari masa ke semasa supaya boleh dipelajari lagi untuk masa akan datang.

Norhayani Mat Jamlus, MP Ipoh

Terima kasih.

Nusyahida Md. Jani, MD Kuala Selangor

Terima Kasih

Norashida Nazri, Nazri, JPBD Negeri Perak

Sepanjang 2 hari kurus QGIS ini, didiapati QGIS mampu memudahkan lagi dan pengurusan /updataing data GIS. Kursus ini perlu lebih meluad diajar kepada semua Jabatan/ agensi yang terlibat di dalam menggunapakai GIS. Ini sekali gus mengelakkan daripada QGIS ini tak kubur begitu sahaja memandangkan hanya sebilangan pegawai didialam sesuatu Jabatan/agensi diajar QGIS.

Rohana Mohamed Kassim, MP Seberang Perai

QGIS merupakan perisian yang bagus dan lebih mesra cuma dan pemahaman memandangkan  ia agak  sukar difahamai dari segi step 

Ahmad Khairdun Wahab, PTD Cameron Highland

QGIS adalah sumber terbuka dan ianya percuma. Ianya perlu disebarkan dan digunapakai oleh Jabatan Kerajaan.

Hj. S. M. Murad Selamat, MP Alor Gajah

Amat menarik dan memudahkan dalam  sejala tapi  yang penting orang atas OK kita OK aje.

Zawahir Zakaria, Lembaga Kemajuan Pertanian KEMUBU

QGIS senang difahami dan mudah diterolehi. Diharap buat kursus pertengahan.

Mohd. Nadzan Nawi,  Lembaga Kemajuan Pertanian KEMUBU

QGIS sangat menarik daripada apa yang telah saya gunakan dalam software lain seperti MapInfo dan ArcGIS. Software QGIS lebih mudah dan senang dipelajari dan software ini boleh diidapati dengan percuma. Saya berharap tenaga pengajar dapat memberikan tunjuk ajar dalam Internet.

QGIS Mobile deja vu

Where to download qgis installer

It's been quite a while since I toyed with QGIS Mobile as I do not own an Android tablet. But I wanted to see how things have progressed so went back to download the qgis-installer.apk here with my smartphone's browser. Before all this happened, I changed the smartphone screen timeout to 'never timeout' because I wanted to view the total installation process and snap some shots.

After the download completed, a QGIS icon appeared on my smartphone screen. I clicked it which opened the above screen and I selected the 'Download and install QGIS' bar. The installer proceeded to show the screen below:

The screen stated Version 1.9 (build 7) would take up 83mb if downloaded and I selected OK. The installer proceeded to install the application though the screen showed it was actually 87mb as shown below:

However, after download completed, nothing happened as shown below:

Then I realized I should have installed Ministro which I proceeded to using Google Play Store. Just to play safe, I installed both Ministro and Ministro II as shown below:

This time around, the qgis-installer requested to install the QGIS application in the SD card which I selected 'Install' as shown below:

After that, the installer requested to install additional libraries which I selected OK as shown below:

This time I got results and the QGIS start-up screen as shown below:

The tips screen appeared after that. From the size of the fonts, it is obvious that the application was designed for a 10" tablet as shown below:

I closed the tips screen and the familiar QGIS workscreen just like the desktop QGIS appeared as shown below:

I then went over to the About link to look at the details of the application and note that it is still an Alpha version as shown below:

I hooked up my CSL mi 410 smartphone to the computer then looked up the insides of QGIS Mobile. I then decided that the most appropriate place to keep my GIS data would be in /Android/data/org.qgis.qgis/files and went along to create a new folder called 'gisdata' there. I stored a sample .shp file set copied and paste directly from my computer. Using QGIS Mobile, I activated the vector file the usual way I would with the desktop QGIS but using my fat index finger and out it came as shown below:

Looking up my icons in my smartphone, I could see 2 QGIS icons instead: the QGIS installer and now the QGIS application as shown below:

Well, I conclude that any smartphone will not do justice to the QGIS Mobile be it a 7" screen smartphone.  A GIS application be it on a notebook simply requires a larger screen to work effectively  thus it is no surprise that QGIS Mobile was meant I believe for a 10" tablet. Even for me, using my 4" screen smartphone for sms-ing can be difficult because I feel the touchscreen keyboard is fractionally small, what more for GIS. I am hoping my division can secure a 10" tablet next year so that I can use it to show QGIS Mobile in action and link it directly to a database server. We'll see...

Troubleshooting QGIS Ver. 1.8.0

Membaikpulih QGIS Ver. 1.8.0

Pada masakini, saya sedang mentransformasi beberapa data spreadsheet GPS kedalam format GIS tetapi dihadapi dengan hasil yang membingungkan dengan Ver 1.8.0. Walaupun tugas mentransformasikan data spreadsheet GPS tidak menjadi isu, masalah berlaku apabila lapisan vektor bertindih dengan lapisan raster, yakni, peta Google Hybrid. Dengan Ubuntu QGIS 1.8.0 pejabat saya, lapisan vektor tidak papar tetapi peta Google Hybrid timbul. Apabila didual-bootkan komputer pejabat,  diaktifkan Windows QGIS 1.7.4 dan data sama diguna, kedua-dua lapisan vektor dan peta Google Hybrid timbul. Dengan sedemikian, saya menyangka Ubuntu OpenLayers plugin 0.61 tidak kompatibil dengan Ubuntu QGIS 1.8.0 berbanding dengan Windows Open Layers plugin 0.61 bersama Windows QGIS 1.7.4 tetapi apabila saya sampai rumah dan diaktifkan Ubuntu QGIS 1.8.0 bersama data yang sama, saya mendapati hasil yang diingini dapat dicapai berbanding dengan Ubuntu QGIS 1.8.0 pejabat. Ini boleh bermakna bahawa Ubuntu QGIS 1.8.0 dirumah mempunyai librari terkini berbanding dengan Ubuntu QGIS 1.8.0 pejabat walhal selama ini, saya sangka kedua-dua perisian mempunyai update terkini. Bagaimana pun, satu boleh dan lagi satu tak boleh laskanakan tugas yang sama? Tak tahu lah... Alangkah baiknya kalau dulu saya dah mengikuti bidang sains komputer!

Troubleshooting QGIS Ver. 1.8.0

I am currently trying to transform some GPS spreadsheet data into a GIS format but am faced by some perplexing results with Ver 1.8.0. Whilst the task of transforming the GPS spreadsheet data is not a issue, a problem occurred when I tried to overlay the vector layer over a raster layer, namely, Google Hybrid map. With my office Ubuntu QGIS 1.8.0, the vector layer refused to appear but  the Google Hybrid map did. Then I dual-booted the office computer, activated Windows QGIS 1.7.4 used the same data and the vector layer appeared along with Google Hybrid map. Thus, I thought Ubuntu OpenLayers plugin 0.61 was incompatible with the Ubuntu QGIS 1.8.0 as against Windows Open Layers plugin 0.61 with Windows QGIS 1.7.4 but when I went home and gave my Ubuntu QGIS 1.8.0 a try with the same data, I found that I could do what I could not with my Office Ubuntu QGIS 1.8.0. This could only mean that my home Ubuntu QGIS 1.8.0 has a more updated set of libraries than my Office Ubuntu QGIS 1.8.0 though I thought both have been updated to the hilt. So how come one can but the other cannot do the same job. Beats me...I wish I had taken up computer science!

SEXTANTE is QGIS's answer to a graphical modeler

Just printed yet to be read in detail

Sexante's pull down menu

Modeler and Toolbox opened

SEXTANTE adalah  modeler grafik QGIS

Kali pertama melihatnya, kerap saya memikir bagaimana modul ini berkaitan dengan seks tetapi selepas memasangnya, saya mendapati ianya lansung tiada kaitan dengan seks tapi merupakan satu alat paling kuat bagi QGIS. Ini adalah jawapan QGIS kepada keperluan modeler grafik dan pada pandangan saya, sungguh cemerlang, saya tabik Victor Olaya, yang pada blognya menyatakan beliau ini akan mula buat kerja lain tapi tidak akan mengabaikannya. About Sexante menjelaskan "It currently contains more than 300 algorithms (Wow!) for both raster and vector data processing, as well as tabular data analysis tools." Saya tidak pernah menggunakan modeler tapi faham konseptnya maka terus mencetak Sexante User Manual dari laman web Sexantegis. Bagaimana pun, Fadzlan yang telah pun dilatih menggunakan alat sama dari ArcGIS, mennunjuk kepada saya cara ianya beroperasi. Beliau bersetuju ianya amat canggih bagi mereka yang tahu mengekspolitasikan Sexante. Ini adalah modul QGIS yang boleh kalahkan yang lain. Kini...tiba masa untuk membaca.

SEXTANTE is QGIS's answer to a graphical modeler

I have always been wondering how this module was related to sex when I first saw it but when I installed it, I found out it had nothing to do with sex but happens to be an extremely powerful tool for QGIS. This is QGIS answer for the need of a graphical modeler and in my opinion, par excellent, I take my hat off to Victor Olaya, who at his blog said he decided to do something else though will not totally abandon it. About Sexante tells that "It currently contains more than 300 algorithms (Wow!) for both raster and vector data processing, as well as tabular data analysis tools." I have never used a modeler though understand its concept so took the liberty of printing his 50 page Sexante User Manual from the Sexantegis website. However, Fadzlan who was already trained in the use of the ArcGIS equivalent, tried it out and showed me how it works. He agreed it is a very powerful tool in the right hands. This is one QGIS module that will shoot down the competitors and put them to shame. Now... time to do some reading.

How to install OpenLayer plugin on a new QGIS 1.8 installation?

Bagaimana hendak memasang OpenLayer plugin pada QGIS 1.8 baru?

Selepas memberi latihan kepada beberapa staf mengenai QGIS dengan Win Ver. 1.7.4, salah seorang peserta jumpa saya pagi ini lengkap dengan notebook menyatakan kesukarannya memasang OpenLayers plugin pada Win QGIS Ver. 1.8. Pada mulanya, saya bingung tetapi kemudian sedar bahawa QGIS Ver 1.8 tidak mempunyai butang Update berbanding dengan QGIS Ver 1.7.4. Untuk mengatasinya, terdapat 2 opsyen:

• Pasangkan QGIS Ver 1.7.4 seterusnya QGIS Ver 1.8 dan OpenLayer plugin akan papar (tentu lah dengan syarat ianya telah dimuat turun kat Plugins/Fetch Plygthon Plugins/Plugins).
• Ambil kaedah lain dan pasang satu-demi-satu berpandukan Nama dan URL Repository yakni  kaedah ini perlu diambil untuk Ubuntu QGIS. Double-click imej kedua untuk mendapati URL  tapi untuk bagi QGIS anda, perlulah menggunakan Add button//enter name & URL/tick 'enabled'/OK. Untuk 'name', tak payah ikut sepenuhnya, contoh, taip 'sourcepole' dan bukan 'Sourcepole Repository' adalah memadai. Kedua, untuk alamat 'URL', taip 'build.sourcepole.ch/qgis/plugins.xml' adalah memadai kerana 'http://' dimasukkan automatik, seperti biasa alamat URL perlu ditaip dalam lower case. Selepas download siap, go to plugins tab/select plugin/install plugin.

Untuk rujukan module Table Manager teletak dibawah QGIS Contributed Repository (kalau tak salah). Kalau menghadapi masalah memasang QGIS Offical Reository 2, ini kemungkinan akibat QGIS Official Repository  menggunakan URL dari QGIS Offical Repository 2. Oleh itu, bagi QGIS Official Repository anda, ambil URL dari QGIS Official Repository 2 i.e. "http://pygis.org/repo/official dan semua akan beres. Yang penting, ianya berfungsi.

How to install OpenLayer plugin on a new QGIS 1.8 installation?

After training several staff on QGIS using the Win Ver. 1.7.4, one of them came back this morning with his notebook to inform that he had difficulty installing the OpenLayers plugin in the Win QGIS Ver. 1.8. I was baffled at first but soon realized that in QGIS Ver 1.8 the Update button does not appear unlike QGIS Ver 1.7.4. To overcome that, there are 2 options:

• Install QGIS Ver 1.7.4 then QGIS Ver 1.8 and the OpenLayer plugin will appear (of course, on condition you selected it at Plugins/Fetch Python Plugins/Plugins).
• Use the long shot and install one-by-one base on the Name and Repository URL which is the way it has to be done on an Ubuntu QGIS. Double-click the second image to look up the URL but for your QGIS, you need to use the Add button/enter name & URL/tick 'enabled'/OK. For the 'name', you do not really have to follow everything, for e.g. typing 'sourcepole' instead of 'Sourcepole Repository' is good enough. Secondly, for the 'URL' address, typing 'build.sourcepole.ch/qgis/plugins.xml' is good enough because the 'http://' is automatically added, as usual the URL address should be in lower case. After download completed, go to plugins tab/select plugin/install plugin.

For reference, the Table Manager module is located in the QGIS Contributed Repository (if not mistaken). If you found problem installing QGIS Official Repository 2, it could be because QGIS Official Repository took the URL belonging to QGIS Offical Repository 2. Thus, for your QGIS Official Repository, just take the URL from the QGIS Official Repository 2 i.e. "http://pyqgis.org/repo/official" and it'll work fine. The important thing is that it functions.

How to use a GRASS module such as v.clean.snap?

Bagaimanakah hendak menggunakan modul GRASS sperti v.clean.snap?

Lanjutan blog mengenai 'How to create a new mapset?', saya kini menganggap akan timbulnya soalan-soalan mengenai cara untuk menggunakan kesemua modul GRASS. Saya terlalu malas untuk menerangkan satu demi satu teknik menggunakan kesemua modul apatah lagi sekiranya pengguna berhasrat unuk menggunapakai aplikasi Open Source kerana tak mampu membeli perisian proprietari, maka, terserah lah kepada pengguna untuk membuat kerja rumah sendiri, dalam kata lain, jangan jadi malas dan berusaha lah sikit. Untuk membantu pengguna mahir, fail pdf step-by-step disediakan sini menunjukkan cara untuk menggunakan modul v.clen.snap module dimana secara konsepnya, modul lain-lain juga mematuhi kaedah sama. Cukup lah disini.

How to use a GRASS module such as v.clean.snap?

Following my blog on 'How to create a new mapset?', I am anticipating questions on how to use the many GRASS modules. I am too lazy to explain one by one all the modules there are there and if one wants to tinker with Open Source applications because one does not want to cough out money to buy a proprietary software then the onus of the user to do his/her homework, in other words, don't be lazy and don't expect things to be spoon-fed. To help users get the hang of it, I present a step-by-step pdf file here how to apply the v.clen.snap module which conceptually all other modules follow the same procedure. Enough said.
