Passwords are case sensitive. ©2009 Vector Limited. Raster/ Bitmap images are made up of pixels, whereas Vector images are created with software and mathematical calculation.s Raster is easy to use but not much common and can be converted from bitmap to another format but cannot convert to vector. GRASS GIS: raster, vector, and imagery analysis A geographic information system (GIS) can be useful tool for describing, modeling, and interpreting data with a spatial reference. Unlike commerical GIS software GRASS is free, and its source code is available for review, modification, or updating.

Some questions that can be answered leveraging vector data include: Which is Best? As we’ve seen there are distinct use cases for using either raster or vector data. 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. Raster Data & Vector data.

Vector tile layers look better on high-resolution displays (for example, retina devices) than raster tiles do. Vector tiles can be displayed at any scale level with clear symbology and labels in desktop applications such as ArcGIS Pro. Vector tiles are much smaller in size than corresponding raster tiles.
