Download Modul: Aplikasi Open Source Quantum GIS untuk Pemetaan

Semakin berkembangnya aplikasi pemetaan untuk berbagai disiplin ilmu membuat developer software-software pemetaan semakin berlomba untuk mengembangkan kemampuan software-nya. Software-software pemetaan yang banyak digunakan saat ini (ArcGIS, ArcView, MapInfo, AutoCAD Map, dll) merupakan software yang dinamis, dalam arti kata selalu dikembangkan sesuai dengan kebutuhan para pengguna dalam pengaplikasian software tersebut. Kebutuhan dalam penggunaan software pemetaan, merupakan cermin dari aplikasi keilmuan dalam menyelesaikan berbagai permasalahan yang muncul dalam kehidupan sehari-hari. Berbagai software pemetaan sangat berguna sebagai alat bantu (tool) dalam problem solving yang muncul pada berbagai penelitian maupun pengambilan keputusan demi kepentingan-kepentingan tertentu. Buku, modul maupun tutorial yang membantu dalam memahami penggunaan software pemetaan pun dapat diperoleh dengan mudah.

Para pengguna software pemetaan sangat diuntungkan dengan semakin banyaknya pilihan software pemetaan yang ada. Software-software pemetaan ini memiliki berbagai macam keunggulannya masing-masing. Bahkan sudah merupakan hal yang lazim bagi seorang pengguna software pemetaan memiliki 2 atau lebih software yang digunakan untuk olah data spasial dalam PC (Personal Computer) atau laptopnya. Hal tersebut dilakukan untuk memudahkan pengguna dalam melakukan pekerjaan terutama yang berkaitan dengan olah data spasial. Seiring dengan berkembangnya software pemetaan oleh berbagai pihak dan tuntutan akan kegunaan GIS pada aplikasi-aplikasi ilmu pengetahuan yang lebih luas, maka banyak pihak mulai mengembangan suatu aplikasi yang lebih murah namun tetap dapat digunakan untuk melakukan pengolahan data spasial seperti halnya pada software-software pemetaan yang berlisensi.

Tidak sedikit juga software pemetaan yang dikembangkan berbasis sumber terbuka (open source) seperti MapWindow, atau Quantum GIS. Tidak seperti software pemetaan yang berlisensi lainnya, software ini dapat dikembangkan sendiri sesuai dengan kebutuhan. Selain itu karena software ini merupakan open source maka dapat diperoleh dengan gratis dan dapat pula disebarluaskan (sesuai dengan ketentuan pengembangnya) tanpa ada pelanggaran hak cipta. Modul, teori, buku acuan dan pelatihan-pelatihan pemetaan belum begitu banyak menggunakan software Quantum GIS karena masih relatif masih dianggap kurang menarik secara visual dan masih dianggap terbatasnya kemampuan-kemampuan software ini dalam pengolahan data spasial yang lebih lanjut dibanding dengan software pemetaan terdahulu. Buku manual atau panduan untuk Quantum GIS versi terbaru dan beberapa versi sebelumnya dapat diunduh pada http://www.qgis.org/en/documentation/manuals.html Melalui modul ini akan diberikan materi pengenalan software Quantum GIS yang bersifat open source sebagai salah satu alternatif dalam pengolahan data spasial.

Open Source GIS All the Way

Want to know about open source GIS? It’s possible it’s lying under your nose and is incorporated into your day-to-day use and yet you don’t realize it sometimes. GIS is essentially ‘geographic information system’, which is an information system designed to capture, integrate, store, manipulate, analyze, manage, and display all forms of geographically referenced data. In case you’re pondering, it is the very kind of system present in mobile phone GPS and what Google Maps or Bing Maps thrive on.

As far as open source GIS in particular goes, since open source can be defined as a software which can be easily accessed and its source code modified, open GIS are information systems which can be easily accessed and the source code manipulated to influence the geographically referenced data it displays.

taken from grassbook.org

Open Source GIS has its edge over the normal package because of a variety of reasons, which is why it is getting more and more popular in the community of programmers. The biggest edge of open source GIS is that it is free. Absolutely free and legal, so talk about low start-up costs. Of course, it’s a feature shared with web mapping services such as Google Maps, hence it makes you wonder why this particular category is experiencing a bloom.

Open Source GIS is more marketable because in this competitive and evolutionary job market, it is a smarter idea to promote a complete GIS software. Since it’s an open source software, community involvement and the interest of programmers in its development really matters—and that is a given, as it has a lot of community support. Using open source GIS is a securer venture than using any other kind of GIS, because it is built in a superior manner than proprietary software. Again, community backing means that bugs and glitches are found and fixed quickly.

The system is much more complete than proprietary GIS software available, as it contains desktop GIS, spatial database storage, a plethora of analysis tools, server and community designed add-ons. Open GIS is also compatible with all major operating systems such as Mac, Linux or Windows. Additionally, it is usually also compatible with older formats of GIS data, so that none of it is ever rendered useless, such as .shp files. It is inevitable that by using open source software, researchers and solution developers can access a wider variety of tools than offered by most commercial alternates.

Open geographical information systems are forming the grounds for any breakthroughs in GIS which can make the access and manipulation of geographical data a much more intricate, focused and user-friendly task. For just about anyone who needs to work with such as system should pick open source GIS rather than restrict his opportunities with a commercial software, made to function but not expand as per needs of the ever-changing technological arena.

Speed up google earth for not wasting the bandwith

Speed up google earth depends on broadband connection. It is adviceable to use routers than using modem. Because modem has limited bandwith and depends on traffic from the operator to recipient. Coverage area also influences connection received by the recipient. Routers connects two or more networks to carry data from one network to another. Routers that connected to server is able to connect to leased line and that is why it has more networks and it does not depend on broadband traffic connection from operator. You do not need to p grade your computer hardware to speed up google earth.

Another reason to use routers to maximizing speed up G earth on your computer is because of routers function is to block traffic data transmitted by broadcast. Compressed or uncompressed data or content you down load or up load will effected to bandwith received. So if you want to make a web for example, it is adviceable to send compressed data or content because it will not waste your bandwith and still able to speeding up google earth. The problem is not all the browser can accept compressed data or content while you up load your data to browser.

Or when you want to use speed up google earth for creating map in your web, you can do the map manually in standard java script map. To make it, first, you must specifying stacking order map elements that you want to make. Then, you create static map using google map API. The last step is remove it from static map to dynamic map. You can try to compress the map before up load it into your web, so there will be no bandwith wasted and able to maximize the speed up google earth both by you and your users.
