			<content:encoded><![CDATA[<p>The installer for Windows XP  is revised as per requested by one of my user.  Two things have changed:</p>
<p>1. With the new release of QGIS, its version is upgraded from 1.3.0 to 1.4.0 in the installer</p>
<p>2. A new python module; Matplotlib ver. 0.99.1 is added.</p>
<p><span id="more-126"></span></p>
<p>Matplotlib is python plotting library. If I could find time, I will implement matplotlib to renew the linked statistical display tool in the sda4pp plugin and remove the iplots package. iplots package is not stable in every OS as much as I expected and difficult to install with its dependencies like Java.</p>
<p>After registration, you can download the installer from this web address:</p>

<p>If SDA4PP is installed, only thing that you should do is to update the plug-in by starting &#8220;fetch the python plugin&#8221; procedure in the QGIS. If you do not know the procedure, it is explained <a href="http://opensourcegisdevelopment.wordpress.com/2009/10/14/how-to-start-sda4pp-plug-in-in-qgis/" target="_self">in here.</a></p>
<h2>Changes since the last major release of SDA4PP:</h2>
<p><strong><span style="text-decoration:underline;">NEW TOOLS:</span></strong></p>
<p><span id="more-119"></span><br />
<strong>1. Clark and Evans Aggregation Index: </strong><br />
Index measures the pattern that is either clustered or ordered. Applying different types of edge correction methods are optional.</p>
<p><strong>2. Local Version of Ripley&#8217;s K and L function: </strong><br />
The tool plots either all local K/L function or only for specific point.</p>
<p><strong>3. Generate Random Point:</strong><br />
The tool generates the random point pattern according to the homogeneous, inhomogeneous or gauss poisson process. Plotting and/or saving the pattern as shape file is also possible.</p>
<p><strong>4. Average Nearest Neighbor Analysis:</strong><br />
The parameters like observed and expected mean distance, ratio and Z-score can be seen in the dialog as the result of analysis.</p>
<p><strong>5. Generate Regular Point:</strong><br />
The tool generates regular point according to the user specified space between the points or the number of points. Study area of regular point can be unit square or any extent of vector layer. Plotting and saving the pattern as shape file is also possible.</p>
<p><strong>6. Nearest Point and Distance:</strong><br />
The tool calculates nearest point and/or distance to either one or two point pattern. The calculation is listed in the dialog. Saving the calculation as matrix as comma delineated TXT file is optional. Another option is to plot the nearest neighbor point with arrows.</p>
<p><strong><span style="text-decoration:underline;">IMPROVEMENTS:</span></strong></p>
<p><strong>7. Quadrat Test Tool: </strong>Calculation parameters can be seen in the dialog and fitting inhomogeneous poisson become possible.<strong> </strong></p>
<p><strong>8. Density Tool:</strong> Resolution of raster images can be increased to get more dense image.</p>
<p><strong>9. Progress bar</strong> is added to each tool.</p>
<p><strong>10. Readqgislayer class</strong> is re-written and more faster now.</p>
<p><strong>11. Setup file </strong>(~135 mb) is prepared to ease the installation of SDA4PP plugin for Windows OS. It is tested under Windows XP OS. How to install the SDA4PP plug-in by using this setup file is explained <a href="http://opensourcegisdevelopment.wordpress.com/2009/10/15/how-to-install-sda4pp-system-0-7-3/" target="_self">as PDF files in here.</a></p>

			<content:encoded><![CDATA[<p>After the completion of installation of SDA4PP external dependencies,  there are two steps that should be performed in order to use the plug-in in the QGIS. First the plug-in should be installed via Internet connection and then loaded by activating in the QGIS Plugin Manager. The steps are explained as below:</p>
<p><span id="more-99"></span></p>
<p><strong>Note: </strong>SDA4PP plugin has several external dependencies.  Before installing the plug-in, you should make sure that all dependencies are installed. Without dependencies, the plug-in will not work correctly.</p>
<p><a title="Development Environment" href="http://ggit.metu.edu.tr/~volkan/development_environment.html" target="_blank">The dependencies are listed in here.</a></p>
<p><a href="http://opensourcegisdevelopment.wordpress.com/2009/10/15/how-to-install-sda4pp-system-0-7-3/" target="_blank">How these external dependencies could be installed is explained in here.</a></p>
<p><strong>STEPS TO BE PERFORMED:</strong></p>
<p>1. run Quantum GIS</p>
<p><strong>A. INSTALL THE PLUG-IN</strong></p>
<p>2. click &#8220;Plugins&#8221; menu and then click &#8220;Fetch Python Plugins&#8230;&#8221; commands</p>
<p><strong>Note: </strong>if &#8220;Fetch Python Plugins&#8221; command could not be seen in the &#8220;Plugins&#8221; menu,  &#8220;Plugin Installer&#8221; in the &#8220;QGIS Plugin Manager&#8221; window should be checked in order to activate the &#8220;Fetch Python Plugins&#8221; command.  &#8220;QGIS Plugin Manager&#8221; window can be reached by clicking &#8220;Manage Plugins&#8230;&#8221; commands in the &#8220;Plugins&#8221; menu.</p>
<p>3. In the &#8220;QGIS Python Plugin Installer&#8221; window, click &#8220;Repositories&#8221; tab, click &#8220;Add 3rd party repositories&#8221;, and then answer to &#8220;OK&#8221;.</p>
<p>4. return to &#8220;Plugins&#8221; tab in the same window, filter to &#8220;Volkan Kepoglu&#8217;s Repository&#8221; by changing the combobox, or find the &#8220;Spatial Data Analysis Plugin for Point Pattern&#8221; plugin from the list.</p>
<p>5. click &#8220;Spatial Data Analysis Plugin for Point Pattern&#8221; and then &#8220;Install/upgrade plugin&#8221; button to install the plugin from the Internet.</p>
<p>6. click &#8220;Close&#8221; button to close the window.</p>
<p><strong>B. ACTIVATE THE PLUG-IN</strong></p>
<p>7. click &#8220;Plugins&#8221; menu and then click &#8220;Manage Plugins&#8230;&#8221; commands.</p>
<p>8. find &#8220;Spatial Data Analysis Plugin for Point Pattern&#8221; from the list in the &#8220;QGIS Plugin Manager&#8221; window and check the plugin to load.</p>
<p>9. A new menu named as &#8220;SDA4PP&#8221; should be seen in the QGIS.</p>
<p><strong>HAVE FUN !!!</strong></p>
<p>You can use the plug-in with your sample data.</p>

			<content:encoded><![CDATA[<p><strong>Sürüm 1.0.0 Yayınlandı</strong></p>
<p>QGIS sürüm 1.0.0, 2009 yılının Ocak ayının başlarında yayınlandı. Böylece QGIS yedi yıllık bir geliştirme sürecinden sonra 1.0 sürümüne ulaşmış oldu. QGIS gelişmesini uluslararası gönüllü geliştiricelere borçludur. Arkasında onu resmi bir şekilde destekleyen güçlü bir firma bulunmamaktadır. Mali sıkıntılar nedeniyle çoğunlukla gönüllü katkıları ile geliştirilmeye devam edilmektedir. Bu yüzden gelişmiş bir API’ye sahip değildir. Sürüm 1.0’ın yayınlanması ile birlikte API kütüphanesinin daha kararlı bir yapıya kavuşacağı umulmaktadır.</p>
<p><span id="more-87"></span></p>
<p><strong>1.0.0 Kurulum</strong></p>
<p>19 Şubat 2009 itibariyle Linux ve Mac işletim sistemleri için tek başına kurulabilen bir setup dosyası yayınlanmıştır. <a href="http://qgis.osgeo.org/download/binaries.html" target="_blank">indirmek için tıklayın.</a> Ubuntu 8.10’da bizzat test ettim. Hiç bir sorunu yok. Gayet güzel, hızlı ve hatasız bir şekilde çalışıyor. <strong> </strong></p>
<p><strong>Windows Kullanıcıları: 1.0.0 kurulum dikkat!</strong></p>
<p>Sürüm 1.0.0 ile birlikte Windows için kurulum biraz sıkıntı hale geldi. 1.0 sürümü Windows işletim sistemine OSGEO4W projesi için hazırlanan bir setup dosyası ile birlikte kurulabilmektedir. Bu setup dosyası Windows kullanıcılarının alışık olmadığı bir şekilde çalışmaktadır. Setup dosyası seçilen paketleri internetten önce indirdikten sonra Linux dizin yapısının bir benzerini seçilen klasör altına kurmakta ve oradan çalıştırmaktadır. Bu setup dosyasını kullanarak nasıl kurulduğuna bakmak için <a href="http://wiki.qgis.org/qgiswiki/OsGeo4wSetup" target="_blank">şu linki</a> ziyaret ediniz.</p>
<p>Eğer bu şekilde QGIS’i kullanmak istemiyorsanız QGIS’i kaynak kodundan derleyerek kurabilirsiniz. Derlemek kelimesi size yabancı geliyorsa bu yolu seçmenizi hiç tavsiye etmem. Derlemenin nasıl yapılacağı <a href="http://wiki.qgis.org/qgiswiki/BuildingFromSource" target="_blank">şu sayfada</a> anlatılmıştır.</p>
<p>Veya bir önceki sürüm olan QGIS 1.0.0.preview2 setup dosyasını kullanarak Windows XP’ye rahat ve kolayca kurabilirsiniz. <a href="http://download.osgeo.org/qgis/win32/QGIS-1.0.0preview2-Setup.exe" target="_blank">1.0.0.preview2-setup.exe indirmek için tıklayın.</a></p>
<p>Vista altında kurmaya çalışanlar için ise önerim “Program Files” dizini altında kurmak yerine direk “C:\qgis” gibi yeni bir dizin altında kurmanızı öneririm. Kurmayı başarabilseniz bile QGIS 1.0.0.preview2 Vista altında doğru çalışmıyor. Özellikle attribute table açmaya kalktığınızda program çakılıyor. Bu hata Vista’dan mı yoksa QGIS’den mi kaynaklanıyor bilmiyorum, ama Açık Kaynak Kodlu Yazılımlar ile Vista’nın yıldızları daha uzun bir süre barışmayacak gibi geliyor. Bu süre çıkacak olan Service Pack’lere bağlı olduğu için bu konuda beklemekten başka yapılacak bir şey yok. Belki de fazla beklemeye gerek kalmaz. Windows 7 Temmuz 2009’da yayınlanacakmış. <img src='http://s2.wp.com/wp-includes/images/smilies/icon_smile.gif' alt=':-)' class='wp-smiley' /> </p>
<p><strong>Python dili ile geliştirme yapmak: Kolaylık, sadelik ve zarafet </strong></p>
<p>QGIS’de geliştirme yapmanın en büyük avantajı Python dilini kullanabilmektir. Python dilinin faydalarını burada uzun uzun anlatmak istemiyorum, ama bence en büyük faydaları derlemeye gerek olmadan kullanılabilmesi, söz diziliminin sadeliği ve kolaylığı, hem betik dilinin tüm avantajlarına sahip olması hem de temel olarak ihtiyaç duyulan kütüphaneleri ile birlikte gelmesi (batteries included), gömülü bir sistem dili olarak kullanılabilmesi ve C,C++, Fortran ve Java (Jython ile) gibi diller ile yazılmış kütüphanelere bağlanarak kullanılabilmesi (embeddable ve extendable olabilmesi) sayılabilir.</p>
<p><strong>QGIS Debug in Windows </strong></p>
<p>Python dili ile yazılan bir eklentiyi denemek için QGIS çalıştırıldığından kodlar otomatik olarak QGIS içine gömülmüş olan Python derleyici sayesinde yorumlanır. Yorumlanma sırasında hatalı bir kod ile karşılaşılırsa hata mesajı geliştiriciye gösterilir. Bu şekilde gerçekleştirilebilen hata ayıklama (debug) yöntemi daha da özelleştirilebilir. Özellikle değişkenlerin hangi değeri döndüğü öğrenilmek isteniyorsa kendiniz tarafından da basit bir şekilde yazılabilecek bir loglama sistemi kullanılabilir. Bu şekilde gerçekleştirilebilen hata ayıklama yöntemi sizin için yeterli değilse, geliştirme ortamınızı bir IDE ortamına (Windows kullanıcıları için Visual Studio 2003) taşıyarak da eklentinizi geliştirebilirsiniz. Bunun için gerekli talimatları Building From Source Code sayfasındaki <a href="http://wiki.qgis.org/qgiswiki/BuildingFromSource#head-696307823157d4af8ddd12c81acdbea284576a5f" target="_blank">7. Maddede</a> bulabilirsiniz.</p>
<p><strong>Genel bir değerlendirme </strong></p>
<p>QGIS, sonuç olarak değerlendirildiğinde kullanıcılar için sınırlı özellikler sunan bir CBS programı olarak karşımıza çıkmaktadır. Şu an için hiçbir açık kaynak kodlu masaüstü CBS yazılımı, sahipli CBS yazılımları ile yarışabilecek ölçüde gelişmiş özelliklere sahip değildir. Ancak hepsi de kendi alanlarında hızla geliştirilmeye devam edilmektedir. Eğer bir kullanıcı olarak beklentiniz, zengin içerik ve gelişmiş hazır araçlar sunan açık kaynak kodlu bir CBS yazılımı arıyorsanız, kişisel fikrim ilk geliştirilen ve hala güncelleğini koruyan bir yazılım olan <a href="http://grass.itc.it/" target="_blank">GRASS</a> veya Avrupa Birliği fonu tarafından desteklenen İspanyol Bölgesel Hükümeti tarafından ESRI’nin ArcView GIS 3.x yazılımına alternative olması için geliştirilmeye başlanan <a href="http://www.gvsig.gva.es/" target="_blank">gvsig</a> yazılımına yönelmenizi tavsiye ederim.</p>
<p>QGIS ise, daha çok CBS ortamında özel bir sorunu çözmek için API düzeyinde kişiselleştirme yapmak isteyenlere, veya  sadece coğrafi veriyi görselleştirmek için kullananlar veya CBS’yi kullanarak başka sistemlere (ERP, CRM, Spatial Decision Systems, Location Based Services) entegre etmek isteyenler veya belirli bir sorunu çözmek, test etmek ve bunun için on binlerce dolar ödemek istemeyen geliştiriciler ve kullanıcılara hitap eden bir masaüstü CBS yazılımıdır.</p>
<p><strong>Özet olarak: Son Söz </strong></p>
<p>QGIS, zengin içeriği veya sahip olduğu gelişmiş özellikler yerine temel olarak bir CBS yazılımında olması gereken özelliklere sahip olduğu ve Python gibi hızlı geliştirme ortamı (agile software development) sunabildiği için tercih edilmesi gereken bir yazılım ve yazılım geliştirme aracıdır. QGIS’I kişisel olarak kullanma nedenim ODTÜ GGIT Bölümünde Doktora yapmam ve Doktoram için geliştirdiğim/geliştireceğim Mekansal Veri Araçlarını CBS ile entegre edebilmek için gerekli geliştirme ortamını bana sunuyor olmasıdır. Umarım QGIS sizin amaçlarınıza hizmet edebilecek uygun bir yazılımdır. Kişisel olarak Python ile QGIS’de geliştirme yapmaktan büyük bir keyif aldığımı ve çok kısa zamanda (yaklaşık 1 sene zarfı içerinde) tahmin edebileceğimden daha fazla yol aldığımı söylemek isterim.</p>

<p>3.a. Eğer QGIS&#8217;de eklenti geliştirmek istemiyorsanız, başka açık kaynak kodlu masaüstü CBS yazılımlarına bakabilirsiniz. <a href="http://opensourcegisdevelopment.wordpress.com/2009/02/17/hangi-acik-kaynak-kodlu-cbs-yazilimi/" target="_self">Muhtemel listeyi görmek için tıklayın</a>.</p>
<p>3.b. Eğer QGIS&#8217;de eklenti geliştirmeye karar verdiyseniz, sırasıyla aşağıdaki programları kurmanız gerekiyor.</p>
<ul>
<li>Python 2.5.x</li>
<li>QGIS 1.0.x</li>
</ul>
<p>Eklentinize grafiksel bir arayüz eklemek için;</p>
<ul>
<li>Qt 4.4.x</li>
<li>PyQt</li>
</ul>
<p>İlk eklentinizi yaratabilmek için gerekli başlangıç kodlarına sahip &#8220;my first plugin&#8221; adlı bir eklentiyi sizler için oluşturdum. Eklenti deposuna ulaşmak için tıklayın. <a title="Volkan Kepoglu's Python based QGIS Plugin Repo " href="http://sites.google.com/site/pyqgis/" target="_blank">Eklenti Depom.</a></p>
<p>Eğer yeni bir eklenti yazarsanız ve yayınlanmasını istiyorsanız, haber verin depom altında yayınlayabilirim veya kendi eklenti deponuzu yaratabilirsiniz.</p>
<p>İlk eklenti kodlarını inceledikten sonra yapmanız gerekenler;</p>
<ol>
<li> Python dilini daha detaylı öğrenmek
<ol>
<li>Python dilini öğreten o kadar çok kaynak var ki. (türkçe var mı bilmiyorum)</li>
<li><a href="http://wiki.python.org/moin/IntroductoryBooks">http://wiki.python.org/moin/IntroductoryBooks</a> (bunlar arasından bence başlangıç olarak en iyisi: Dive into Python)</li>
</ol>
</li>

<ol>
<li><a href="http://wiki.qgis.org/qgiswiki/PythonPluginCodeSnippets" target="_blank">Python Plugin Code Snippets</a></li>
<li><a href="http://wiki.qgis.org/qgiswiki/PythonBindings" target="_blank">Python Bindings</a></li>
</ol>
</li>
<li>ve diğer QGIS Eklenti geliştiricilerinin kodlarını incelemek
<ol>
