They are commonly used in cases where the dataset is extremely large, or in scenarios where numerous people need to access and edit the data at the same time, possiblyįrom different locations. The most common server GIS system is a spatial database.Ī spatial database is used as an alternative to the file formats discussed earlier.
Generally they are only used for large scale mapping efforts and very specific niche tasks. The steep learning curve of Server GISĪs you are new to GIS you likely won’t need to concern yourself with server based GIS solutions. If a web GIS has the lowest barrier to entry, then a server GIS definitely has the highest, with by far the steepest learning curve. We will be going into much more detail regarding the benefits of web GIS. The next chapter is devoted exclusively to web GIS.
Now web maps can be created for a very low cost, using a point and click interface in a matter of minutes using nothing more than a web browser! A typical deployment would require programmers, servers and system administrators.īut now thanks to cloud based services such as Mango these barriers to entry have been removed. Web GIS systems used to be very expensive to develop, deploy and maintain. What’s more they can answer those questions from anywhere, anytime, using any web accessible device. Web GIS gives non-expert GIS users the ability to easily interact with map visualizations and answer their own questions without having to involve a GIS team. With the latest generation of super easy to use web GIS systems, all that has changed. Once the map was ready you would take a walk over to the GIS department to view the map on a workstation or collect a print out. In a time before web based GIS systems, when you wanted the answer to a location related question or to view a specific visualization, you would contact the GIS team and ask them to prepare a map for you. Like all forms of information distribution, the internet has completely revolutionized GIS.

Later in this chapter we will take a look at the most popular desktop GIS systems, ranging from free and open source solutions to expensive paid products. Performing queries and visualizing the resultsĭesktop GIS systems are capable of a whole lot more, but these topics are usually a good starting point.Creating visualizations, category maps / quantity maps / heat maps etc.So rather than trying to learn everything it’s capable of, it’s best start with figuring out the parts that are applicable to the problemsĪs I mentioned in a previous chapter, for most GIS beginners those problems are: The best way to go about learning a desktop GIS system is through a problem/solution approach. As with tools such as Photoshop or Microsoft Excel, most users can figure out the basics pretty quickly, but becoming a true master can take years. The QGIS Interfaceĭesktop GIS systems are complex programs. They are used for creating, editing, visualizing, managing, and analyzing geographic data.

Most GIS software falls into one of the four categories below Desktop GISĭesktop GIS platforms are the swiss army knives of GIS. For example, we use a desktop GIS system for creating and modifying our GIS data, then once the data is ready we upload it to a web GIS system in order to distribute the maps within our organization.Ĭhoosing the right GIS tool is really about understanding the problems that you are looking solve. This means we use several tool in unison. Often GIS solutions will involve a “software stack”. It’s best to think of GIS software like tools in a toolbox, you don’t want to use a screwdriver to bang in a nail. So I guess the first thing you want to know is which one is best? The answer is… With so many GIS software solutions available on the market, how do we even begin choosing which one to use? In this chapter we will give you the background knowledge that you need in order to answer that questions for yourself.įor those of you that have tried looking for GIS software for the first time, there’s one thing that you will know for sure: you aren’t short of choices.
