Vector data is a representation of the world using points, lines, and polygons. This data is created by digitizing the base data, and it stores information in x, y coordinates. Vector data is one of two primary types of spatial data in geographic information systems (GIS) – the other ...
This information is represented by a set of numbers called a vector. The vector index holds this data and “indexes” it in a way that helps a database quickly identify and match objects. A vector database houses these indexes and the objects they describe. However, how a database ...
Find the definition of GIS. Learn how this mapping and analysis technology is crucial for making sense of data. Learn from examples and find out why GIS is more important than ever.
Whether the data is from government, private sources, or open data, it’s important to understand the type of data, where it comes from, how it is collected, and what it can be used for. Fromvector to raster, or web-based to multi-temporal, here are some of the most common types o...
The two primary types of spatial data arevector and raster datain a GIS. But what is the difference between raster and vector data? When should we use raster and when should we use vector features? Find out more about the spatial data models commonly used. ...
What is GIS used for? Who uses GIS? Is GIS data Vector or Raster? Is GIS the same as Geospatial? What is Geospatial Data? What is Geospatial Technology? Did you know? More Back to Basics: If you work in the CAD/BIM industry, you've likely heard of GIS, but what is it exactly...

Location data is an incredibly useful resource when properly analyzed. The first step is to choose an interactive platform that offers maximum governance with the flexibility to use multiple sources, custom filters, and the ability to perform a diverse set of analyses. If you do your homework and...
In the mid-sixties, two applications, SYMAP and GRID, laid out the theoretical foundation for the analysis ofrasterandvector data, the two main approaches for encoding and storing geographical information (we will explain them in detail in the upcoming chapters). The main ideas for performing ana...
One of the key developers working on the data browser, Nirvan Theethira, describes the technical background of this enhancement: The core of the improved search experience is the meaning vector representations of variable descriptions. This is done using a pre-trained sentence...
