Geoprocessing Practicum in arcview 3.3

Geographic Information System

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.

Geographic Information System (GIS) is a computer-based information system, which is used for processing the georeferenced spatial data (in the form of details, facts, conditions, etc.) are stored in a database and is associated with problems as well as the state of the real world (real world). GIS benefits generally provide information closer to real world conditions, predict an outcome and strategic planning.

In GIS, there are various roles of the various elements, both human as well as experts and operators, device tool (software / hardware) and the object of the problems. GIS is a system circuit that utilizes digital technology to perform spatial analysis. The system utilizes hardware and computer software to perform data processing such as:

1. Acquisition and verification.
2. Compilation.
3. Storage
4. Updates and changes.
5. Management and exchange.
6. Manipulation.
7. presentation
8. Analysis.
(Tor Bernhardsen, 1992 in Budiyanto, 1992).

Geoprocessing is a set of functions that perform operations on the basis of the geographical location of the input layers.

There are 6 geoprocessing functions in that
•Dissolve
•Merge
•Clip
•Intersect

These geoprocessing functions are often also used as a complement of the function Buffer.
