Creating Your Own Application of GIS with Open Source Program

For specific needs, a user not familiar with GIS and do not want to know how a GIS application can be produced, pragmatically, the user wants to perform on-screen map of the location he wants, can zoom in and zoom out, can display the location information and perform simple query. To meet it, a GIS Programmer's going to make a standalone GIS application tailored to the needs of the user.

I've toyed with the ArcView Avenue Script congenital 3.x to customize the order in accordance with the end user. Later still there is a request to be made a standalone GIS application, where the user does not want to know, how to make and what software is behind the application of GIS later.

If you are still playing with Avenue The script, of course, must play well with the legality of the software. But now there is an open source GIS software, which can be used as tools to customize so as to produce a standalone GIS application, which is free to use, not tied to the legality of a software. Examples are MapWindow GIS Software. Aside from being a desktop GIS like ArcView 3.x, the MapWindow GIS ActiveX Control is also available MapWinGIS. By using this control, you can create your own version of your own GIS applications. Another example is gvSIG.

Blog Desktop GIS Book in one of its news, shows how to create a GIS application that you can make your own by utilizing some of the Open Source GIS software follows:

QGIS 1.0
PyQt4
Qt 4.3 or higher and the development tools (Designer)
Python 2.3 or better
For more details please go to the post: Creating a Standalone GIS Application section first. You still have to wait for posting of the next Desktop GIS Book that will show you how to add some features needed in a simple GIS application.

TatukGIS Editor Version 3.0 Released with 3D Feature Mapping

TatukGIS Editor is a desktop GIS mapping software at the same time spatial data editing applications that can be customized using scripting tools that are already available in it. The user interface of GIS software is available in 16 languages​​.


TatukGIS Editor itself has just released the newest version V 3.0 with 3D Mapping features include:

3D viewing seamless integration
3D capabilities include the presentation of DTM (digital terrain models)
3D vector rendering, automatic draping of a 2D image and vector layers over DTM models
flood simulation, fly-over, control lights, powerful camera / observer control
If the project folder DTM data available, automatically the data can be used as a 3D model. With the ability TatukGIS Editor which has a built-in scripting tools, you can create an application program to perform customization of data / maps available. You can program such as flood simulation by adjusting the camera angle when the position of the fly, etc..

TatukGIS Editor V3.0 The latest release of March 22, 2011 is available in the paid version and trial version. You can also download for free TatukGIS Viewer. Viewer has owned all versions of the data minus Editor creation / editing, scripting, and features 3D viewing. You must register first to download trial versions and free versions.

Google Maps 5.7 for Android Provides Features Download Area Map

Google Maps 5.7 for Android was released yesterday with a new feature "Download Area Map" which serves to download the maps Google Maps to be used offline. This feature can be activated via the Labs page.


Features "Download Map Area" to Obtain a map of Google Maps Will download the area with a radius of 10 miles from the location of the user chose. Users can still download it again the other locations That overlap with the previous map.

The process of downloading the Google Maps map may take Several minutes. Just save the downloaded maps "landmarks" alone, not including satellite images and 3D building.

You can see a demo video "how to download Google Maps data for offline use" on www.AndroidCentral.com:

Download Area Features Map is useful for the traveler Pls They want to visit other areas, but worried about the quality of internet connections in the area. By first downloading the folder to be opened offline, at least That worry can be eliminated. Read also features a "Transit Navigation" on Google Maps 5.7 for Android here.

To you the traveler the WHO does not have a phone or a tablet with the Android operating system, but want to download maps from Google Maps to destinations of your visit,

Creating KML from Shapefile Using 3D SHP2KML Freeware

this post will show you how to create KML files 3-dimensional (3D) data from the shapefile using the freeware SHP2KML to display in Google Earth. Shapefile data I use is the same data to show an example of using fusion to google shapefile conversion tables, population census results of 2010 in Central Jakarta.The end result of the example that I made this as shown in the picture above. Where to look 3D view of data such as population bar graph, with each sub-district boundaries appear below. That looks like a bar graph is a polygon shapefile format from the centroid in each district. The shapefile is in the process of using a freeware 3D KML SHP2KML to be, while the district boundary is a two-dimensional shapes are also created using the same application.

OK, the following steps to create a 3D KML from shapefile data using freeware SHP2KML.

Specify shapefile data input and system coordinates. It is strongly recommended you use the unit shapefile Geographic (Lat / Long). Click Next.
Here you set the display when the mouse will hold to its features, information from attribute columns in which you want to perform, as well as determining the choice of the color feature that will automatically change to follow the movement of the mouse (if it displays the label roll over). For the symbology you can specify unique value based on a specific column (of type string or numeric) or a single symbol or Graduate Value based on a column of type numeric.
Here you set the color of your choice prior symbology. You can adjust the color by clicking the default colors available.
This stage you set what columns you want in the show feature when clicked by the user which will perform a balloon as shown in the picture at the top (data Kecataman Cempaka Putih). You also can set the background color and font color table as you wish.
At this stage you can fill the layer title and description. The most important thing at this stage is that the 3D settings in the Options. Make sure the 3D option in check, then it adalaha Altitude Mode Relative to Ground, and select Field Value in accordance with the data you want visualized as three-dimensional shapes. Finally, set the value on the field Factor. In this example, I am content 0.01 or one hundredth of the value of his data so that the resulting 3-dimensional shape is not too high.
Click Create or Create and Open KML for display in Google Earth directly. The result as shown in the picture above this post.
You can also create sub-district boundary with the polygon into 3D format as shown below. Which is more interesting and informative do you think?

Edit & Convert KML Using GDB to RouteConverter

GDB conversion to KML can be easily done on Google Earth, but I often receive GPS data tracking the results of engineers in the office who need a lot of editing because of several reasons. In Google Earth it is difficult to do the editing track or route. By using the free application without installation called RouteConverter this, the editing process route, track and waypoint becomes easier.RouteConverter is also a cross-platform applications that can do the conversion to various types of file formats. There are about 70 types of file formats supported by Java-based application that can be used on Linux, Windows and Mac this.

You can display the route, track or waypoint using the background maps from Google Maps on this RouteConverter applications. You also can change the display background maps from OpenStreetMap. It is also possible to complete the elevation data on the track, route and waypoint from SRTM data. You need an internet connection to be able to utilize all of these features.
