With the utility of R, many popular statistical procedures and more advanced analyses, including a variety of simulation applications, can be applied directly within GIS tools such as QGIS.
Anthony Calamito, Chief Evangelist at open source GIS company, Boundless, explores how companies can harness the power of their open source GIS systems by building hybrid architectures that include their existing software.
As 2016 comes to a close, it’s time to start turning your attention to the upcoming New Year and reflect on what steps to you can take to improve your GIS skills and participate more in the geospatial community.
To get the most out of QGIS it’s not enough to simply know how to write the lines of code you need, and how to integrate with other exciting tools but rather, the more control you have over a tool like QGIS, the more you’ll be able to visualize and explore your ideas.
Relational databases present some limitations to scaling, preventing or limiting the applicability of big data and real-time data problems utilized within GIS. More and more GIS software companies and developers are adopting NoSQL formats where data retrieval is generally faster and easier to structure. NoSQL also facilitates analysis and integration within a variety of tools, which is why open source GIS has proven to be the most useful arena for NoSQL databases.
The need to understand emergent phenomenon in a variety of fields has led to not only greater use of agent-based models (ABMs), but we are increasingly seeing tools that integrate GIS with ABMs.
An open source application by definition is software that you can freely access and modify the source code for. Open source projects typically are worked on by a community of volunteer programmers. Open source GIS programs are based on different base programming languages. Three main groups of open source GIS […]
Bob DuCharme, a technical writer with CCRi, writes about how open source GeoMesa can help users with managing large spatio-temporal datasets. GeoMesa can stored petabytes of GIS data and serve up tens of millions of points in seconds.
