Vector data is used to represent real world features in a GIS. A vector feature can have a geometry type of point, line or a polygon. Each vector feature has attribute data that describes it. Feature geometry is described in terms of vertices. Point geometries are made up of a single vertex (X,Y and optionally Z).

It is developed by ESRI – Environmental Systems Research Institute. It is a simple, non – topological format used for storing geometric location and attributes of Geographic data. Shapefile represent geographic data into points, lines or polygons. Where vector data (coordinates that create an image) is somewhat abstract, raster data is quite literal. Raster data is grid or pixel based. Commonly found as aerial surveys, topographic maps, and satellite imagery, raster file extensions include TIFF, PNG, and JPEG.. In GIS mapping, raster data generally represents surfaces..

Creating Vector Data in ArcGIS In this workshop, you will learn how to derive vector features from a raster dataset. As sample data, a USGS quad sheet and one type of each shapefile are provided. I. First, prepare the demonstration data a. Download and extract VectorEditing_DemoData.zip from the CDS website and extract it. b.

Point geometries are made up of a single vertex (X,Y and optionally Z). Within the spatial referenced data group, the GIS data can be further classified into two different types: vector and raster. Most GIS software applications mainly focus on the usage and manipulation of vector geodatabases with added components to work with raster-based geodatabases. Vector data. Vector data is split into three types: point, line (or arc), and polygon data. Point Data. Point data is most commonly used to represent nonadjacent features and to represent discrete data points.
