You can also add or remove certain elements from the image-for example, you could remove all text from the image. This means that you could color a certain building, or all buildings within the image. Essentially, vectors are infinitely scalable. You can also edit individual elements within a vector image, as well as certain classes of elements. These elements appear the same at any scale, meaning you can zoom into or out of the image whilst maintaining quality. Instead, they are used to represent discrete data points/points of interest e.g. Points have zero dimensions, so you cannot use them for measuring.Lines are one dimensional, so you can only use them to measure length and represent linear features e.g.Polygons are two dimensional, so you can use them to measure a perimeter or area e.g.Whereas a raster image is made up of pixels, vectors are composed of lines, points, polygons and text: Vector images, meanwhile, are much more dynamic. On the right is a zoomed-in section of the map, which has maintained its quality. The image on the left is a vector map of the city of Cluj-Napoca, Romania. This means that when you zoom into a raster image, it will lose quality and become pixelated. It is not possible to edit or remove individual elements within a raster image-the user is restricted to making edits which affect the image as a whole, such as inverting the colors of the map. As with other raster images, they also face the issue of not being scalable due to their resolution dependency. When used in a GIS, raster images act as a backdrop. These maps may either be raster images or a vector images. In order to understand the geographic data, GISs include maps. As a reflection of its ubiquity, learning to use GIS is now a key component of many college programs. Nowadays, a wide range of industries use GIS: insurers, railway companies, retailers, and many others. With faster processing speeds and cheaper file storage, GIS became commercially viable and widely adopted.
#Arcmap convert raster to vector software#
Before the widespread adoption of GIS, there was thus a gap in the market for software which could analyze geographic data. It’s easy to see why: geographic information is crucially important for both the public and private sector for businesses and for individuals.
Whilst GIS was once niche, it has recently exploded into the mainstream. It also makes it possible to overlay the data with custom fields-for example, to display store opening times next to its location on a map.Ī screenshot of GRASS GIS, an example of a Geographic Information System Who uses GIS? It enables the user to view both geographic information and data about the demographics of a certain area side-by-side.

Want to know more? Read on to learn about how industries use GIS why you should choose a vector image and how to convert your raster image to one of the most popular vector formats around: DXF.Ī Geographic Information System is a piece of software that allows a user to view and analyze map data. Whilst both have their pros and cons, there are some clear advantages to choosing a vector image. This map can either be stored as a raster or vector image. In order to read and analyze this data, you need to use a geographic information system, or GIS.Īt the base of every GIS is a map. Geographic information is now so ubiquitous that 80% of the world’s stored information contains a geographic element. This enables it to be located on a map, and displayed alongside relevant data. Every building, road, and fixed structure in the world has geographic information.
