A map data structure and method and system for obtaining geographic information. Raw map data is converted into map data structure by generating an attribute layer for each geographic attribute according to a defined line pattern and line width, and defining a bit-array of fixed bit-length for ...
Main vector file types What are the main raster file types? JPEG (.jpg, .jpeg): A commonly used compressed image format that reduces file size by discarding some image data. Best for photographs and images with gradients. PNG (.png): A lossless image format that supports transparency. Ideal...

Display vector or raster data on mapVector data represents events, locations, and objects using points, lines, and polygons. For example, you can represent a city by using a point, a river by using a line, and a country by using a polygon. Raster data stores gridded data, such as sat...
Every house, every tree, and every city has its own uniquelatitude and longitude coordinates. The two primary types of spatial data arevector and raster datain a GIS. But what is the difference between raster and vector data? When should we use raster and when should we use vector features...
One of the primary differences between the two formats is the structure. Raster images are made up of a finite number of pixels. Vector art, on the other hand, is deeply rooted in mathematical equations or geometric shapes; hence, its data is more about lines, points, and polygons. ...
