You will be able to adjust settings and even perform edits before saving the new vector image.
There are two major types of geometric data model a. Vector Model Vector model uses discrete points, lines and/or areas corresponding to discrete objects with name or code number of attributes. b. Raster Model Raster model uses regularly spaced grid cells in specific sequence. An element of the grid cell is called a pixel which contains a single value of attributes. Vector Data Structures â¢ The method of representing geographic features by the basic graphical elements of points, lines and polygon is said to be the vector method, or vector data model
