What is GIS?
Tools that help visualize complex geographic information
Geographic Information Systems (GIS) are tools to capture, store, edit, analyze, manage, and present geographic information visually. Software for GIS enable all levels of geographic knowledge workers to create queries, investigate spatial data, edit spatial data (points, lines, and shapes), and present mapping information.
Combined with this visual data is “attribute data” which provides more detail about the shape. For example, a shapes of school buildings would likely include attributes like the name of the school, year built, students/teacher population, etc. GIS solutions can help answer complicated questions including “Show me all the fire hydrants within 200 yards of the schools in this city.” If the data is available and accurate, a GIS tool can highlight this information, and decision makers easily interpret the results.
Example of GIS Overlays
Imagine different sets of information visually stacked on top of each other. Looking at the image to the left, see groups of objects stacked visually on top of each other in this order:
- Tress and vegetation
Depending on your needs, there are various software solutions for managing, editing, querying, and presenting GIS information. Most GIS Analysts need two things:
- Basemap – an image that acts as a bottom layer upon which to present geographic information. This is usually a photograph of land or water from the top down, and is meant to provide visual context to the shape data being presented.
- Shape data – points, lines, or shapes of information on top of a basemap. For example, you can show a proposed changes to a highway on top of a photo of the current road structure.
Canvas X GIS software allows you to import and export geographic information in many common formats that let you show information on different layers, edit shapes, perform complex geographic queries, and create incredible graphics & presentations in one application.
How different people use GIS data
There are different uses for GIS tools and data, and one needs additional knowledge for more complicated tasks. The most common use is for end users needing accurate, complete datasets to understand mapping information. Whether you need GIS information to navigate to a new coffee shop or you need a visualization of a large construction site, presentations help visualize complicated geographic data.

GIS Data formats
GIS data comes in various formats:
- Photos of top-down images
- Google KML/KMZ
- CAD dataset
Canvas X GIS supports many GIS formats and other image/vector formats. See our list of compatible import and export formats >>
One of the great values of the Canvas software is in its collection of file format translators.
Where can I get GIS data?
Many states, counties, provinces, cities and municipalities provide access to their geographic data. Simply search for your location and look for “shape files”. For example, Miami-Dade County has much of their data freely available for download. You can find paid or free mapping data in many places – just make sure the data is from a reputable source and up to date.
- Geographic Information Systems market is estimated to be worth $17.5 billion by 2023.
