Geographic blogger blogger geographic code have been created at the hands of Moroccan teledyne blogger Krier Hamid student geographic town of Beni Mellal. The goal of this blog is to share my experience and all that I have learned in my career with the rest of the humble school teledyne students Menu

- Raster data represent phenomena that sign on the map in the form of a point-economic and coordinates ray (well - appointed - City site ...)
- Written statements that take the form of a line on the map, to be completed connecting a series of dots in a row by the different coordinates (roads - irrigation canals teledyne - Water Network ...)
Line
Known in the field of geographic information systems on the lines of the term brackets (Arcs) and the starting point and end point of the arc node (Node) and the blobs that mediate nodes Summit (Vertex) form.
After numbering linear data elements of the group process in the emergence of errors and shortcomings increases Overshoots Undershoots Spikes and bumps appear. This requires the user of errors corrected by connecting elements between them and the abolition of the increases to be ready to receive data bases.
Interested in this type of GIS data processing network, which consists of a small spatial units square shape called Pixel, a shorthand term for the English Picture element, it is entered into the computer by a scanner or imported from space visualization files. And thematic information associated with each single value associated Palmngarh be represented
The accuracy of the data associated with a degree of clarity of this model (Degré de résolution) Ntoffer For example, on a satellite image at a resolution of 30 m / 30 m can not be in this case the distinction between the two houses in the area of urbanization. The degree of clarity associated with the level of detail that we want to be represented, and if the degree of clarity lift brings the number of squares and increase the time of analysis, as well as dedicated to storing files in the computer space. In addition to the representation of the field elements of this model allows the study of the ongoing shifts in the area.
