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.
Vector data is the representation of a geospatial element through its x and y coordinates. The most basic form of vector data is a point. Two or more points form a line, and three or more lines form a polygon. For example, Google Maps—a common web map and visual representation that us...
Geometry is the branch of mathematics dealing with spatial relationships, measures, and properties of points, lines, and surfaces. In GIS applications, vector geometry is used to represent the spatial component of geographic features with discrete boundaries such as wells, rivers, states, streets, an...
What is Location intelligence? While Geographic Information Systems (GIS), in one form or another, have been around for several decades, we believe that one of the reasons it has been slow to break through into mainstream information technology is the use of over-complicated terminology.GIS,spati...
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. ...

An example of the Built-In Login Window for ArcGIS Enterprise Why authentication matters Before we start to talk about the different types of authentication, we need to understand why it matters. In today’s digital age, securing your GIS data...
Learn how to summarize locations using the Nearby capability in infographics and reports. For example, see a tabular summary of how many and which existing restaurants are within a mile of a proposed quick-service restaurant, including where and how far they are using an interactive map. To lea...
A base map is a reference to display more intricate data, including boundaries,topography, and both vector and raster information. It shows only the basic outline of the roads or geographical features without any additional detail. What does base on the map mean?
What is the difference between a plotter and a printer? The main difference between a plotter and a printer lies in the output they produce. Printers are designed to create raster images by applying ink or toner directly to the paper. On the other hand, plotters generate vector-based output...
