Vector Data and Raster Data in GISAli Jaafar
Because vector data have vertices and paths, this means that the graphical output is generally more aesthetically pleasing. Furthermore, it gives higher geographic accuracy because data isn’t dependent on grid size. Topology rules can help data integrity with vector data models. Not only that, ne...
What types of GIS data are there? GIS data can be separated into two categories: spatially referenced data which is represented by vector and raster forms (including imagery) and attribute tables which is represented in tabular format. Within the spatial referenced data group, the GIS data can...
Natural Earth is a public domain map dataset available at 1:10m, 1:50m, and 1:110 million scales. Featuring tightly integrated vector and raster data, with Natural Earth you can make a variety of visually pleasing, well-crafted maps with cartography or GIS software. ...

EPS (Encapsulated PostScript): A legacy file format that can include both vector and bitmap data, often used for high-resolution printing. Compatible with many graphic design programs but lacks advanced transparency and layer support. PDF (Portable Document Format): Although primarily for document ...
