Spatial Data Input

Creating a spatial database in a GIS can happen in two ways:...

Entering the Attribute Data

Attribute data is information about a place or thing that isn’t about its location. For example, if you’re talking about a road on a map, the attribute data might include things like how wide the road is, what it’s made of, how much traffic it gets, and any rules about driving on it. This information can be stored separately from the map itself, either in the GIS as part of a database, or along with the map in a special type of database....

Data Verification and Editing

Spatial data in a GIS need to be checked for mistakes to make sure they’re accurate. Mistakes like missing bits or lines that don’t match up can happen when putting data into the system. One way to find these mistakes is to print out the data and compare it to the original map, looking carefully for any differences....

Geographic Data: Linkages and Matching

Linking spatial and attribute data is a key part of using GIS effectively. If you connect the wrong kinds of data, it can make analyzing the information very confusing. Similarly, making sure different sets of data match up correctly is important too....

Spatial Analysis

The power of GIS lies in its ability to analyze data. What sets GIS apart from other systems is its special ability to analyze data that has to do with places. These analysis tools use both the location and other details in the database to answer questions about the real world. By creating and using models, GIS helps us understand processes in the world around us. These models show us patterns in the data, opening up new ways of looking at things....
