Vector data represents geographic features as discrete points, lines, and polygons. It is scalable without loss of quality and can be easily modified.
In GIS, point data can be used to show the geographic location of cities. Map: Caitlin Dempsey using Natural Earth Data. Line Data Line (or arc) data is used to represent linear features. Common examples would be rivers, trails, and streets. Line features only have one dimension and the...

Spatial data is data related to a location. Some examples include the population of a city, the type of soil in a region, and data from remote-sensing satellites. In the first example, the city could be considered as a location and the population is the data or a feature. In the secon...
Performance can be excellent, and may be very competitive compared to reading an entire data source layer into memory. Really good drivers include ESRI Shapefile, Geopackage, PostgreSQL/PostGIS, MapInfo File, ESRI FileGDB, but there are dozens to choose from....
Vector data storage has various advantages in a cartographic or geographical information system (GIS) environment, but lacks internal spatial relationships between individual features. Quadtree structures have been extensively used to store and access raster data. This paper shows how quadtree methods may...
The service also provides examples of their use. Let’s takeone of these examplesto display a vector layer. Add the link to the Web GIS to the “baseURL” line (32) and the resource ID to the “resource” line (38). Open the HTML page in a web browser to see the map. ...

Here are just two examples of maps I created using OpenStreetMap data, and that heavily rely on Maplex (in fact, all labels were placed by Maplex). I spend a huge amount of time fine tuning the used labeling settings, and there are in fact hundreds of labelclasses at w...
