in ArcView, geoprocessing is a way in which to create new spatial data based existing theme (s) in object view. In most cases (activity) with respect to this extension, users will alter the properties belonging geometric spatial elements while observing changes in the attribute data. The entire main functions in spatial analysis provided here follows its guide (wizard). Overlay maps and join spatial data which is a major force in spatial analysis can be easily understood and carried through this tool. Learn more operations that can be performed spatial extension Geoprocessing is:

1. Dissolve: This process will basically unify or eliminate the boundaries of spatial elements right next to each other but located in a same theme or in other words dissolve an operation that used to unite the features that have the same attribute values.

2. Union: This process will produce a new theme by combining two themes. Output generated theme is a combination of these two features, the following attributes of the data.

3. Merge: This process is similar to the union will produce a new theme that is a combination of several themes that are side by side, but the spatial elements do not intersect. Data attributes of each theme will automatically be incorporated.

4. Clip: Basically this work is "cut" or cutting out a theme. This process generates a new theme by theme in accordance with the type of object being cut (point, line, and polygon). therefore, the new theme will only contain spatial elements of theme objects contained within the cutter theme.

5. Intersect: The process is basically not much different from the clipping but the intersect, a new theme is the second slice of spatial data themes that become inputs to the theme overlay as its boundaries intersect.

Purpose
1. Students can recognize ArcView software along with menus associated with geoprocessing
2. Students can perform geoprocessing stage with ArcView GIS 3.3 software
3. Understand the geographic information system.

Some causes of anarchist demonstration

by Unknown  |  in Article at  1:52 AM
 1. Thinking of the protesters who argue their demands must be obeyed because it is true.

Demonstration
burning tires in a demonstration
In exercising their various demonstrations view of the demonstrators assume that aspiration that they are calling for an aspiration which represents the conscience of the entire people of Indonesia. If the justification is so believed that the implementation of the demonstration the protesters not merely express opinions could lead to impose opinions.

Therefore, when the demands of the demonstrators have not been able to fulfill it will lead to an anarchist direction with the expectation that they will or aspiration voiced in note.


If the proposal is rejected without weighed
Voice silenced critics prohibited without reason
Accused of subversive and disruptive security
Then there is only one word: opponent ! (Wiji, 1986)


2. Hot and claustrophobic atmosphere makes demonstrators tend to be easily provoked emotions.
Anarchism in the demonstration can also be caused due to the situation when the demonstrations occurred, generally in a demonstration requires a long time and is done during the day, the atmosphere was hot, stuffy and fatigue will easily make the demonstrators to be provoked and irritable.

According to a study published in the journal AS Science, there is a link between high temperature with a quick-tempered attitude. Heat also have a psychological effect that gives aggressive impulses. It can easily be seen, once people feel the heat for several hours.

Buffering is one of the processes in the geoprocessing commonly used in GIS analysis. Buffer or widening / buffer is an area that includes the features (points, lines, or polygons) with a certain distance. Buffers are usually used to represent a range of services or an area that is assumed to be a certain distance to an interest in the spatial analysis. Buffer can be done fatherly type feature polygon, polyline and point.

Making the buffer requires a determination of the distance measured in units (meters or kilometers.) Buffer operation is very important to determine the area of influence of the feature. Buffer will describe a circular region around the point or corridor around the line and the wider region around the polygon. By creating a buffer, it will form an area, polygon, or a new zone that covers (or cover) spatial objects (buffered object) in the form of objects points, lines or areas (specific polygon) with a certain distance.
