GIS in Windows

Data used in GIS can be divided into 2 types of data geometry and attribute data.

1) Data geometry (spatial) showed a spatial (RELIGIOUS) an object. This condition is usually obtained with a spatial mencocokan position of the object with the circumstances of fact in the world. The determination of the geometry of a data point by using GPS (Global Positioning Satellite). Geometry data can be in the form of Raster (pixels) or Vector (Polygon / Area / Line / Point).

a) Raster Data is data that didimpan in a checker square (pixels) that form a field. Position pixels are 2 dimensions to the line with the stated-m-n to the column. This data has weaknesses because it takes too much memory and CPU, which require high processing for high when beresolusi as satellite imagery or photos from the air. Usually, this data is obtained through the process of scanning or shooting with a format like JPEG, tiff, BMP, etc..
b) Vector Data is data that is stored on a line or a polygon closed (the area). Polygon or a line formed by connecting the dots of coordinates (x, y) that have similar values. Because they are vectors of this data does not depend on the resolution. Vector Data consume less memory than raster data. Data stored in the form of the model data vectors, the relation between one object with another object is not saved. In order to be processed through the GIS model of this data must be converted to model saves the data correlation between objects, or through the topology.
