Consider SAGA GIS a prime choice for environmental modeling and other applications. Overall, it’s quick, reliable and accurate. If you have a DEM and don’t know what to do with it – you NEED to look at SAGA GIS. The morphometry tools are unique including the SAGA topographic wetness index and topographic position classification. It’s not particularly useful in cartography but it’s a lifesaver in terrain analysis.Ĭlosing gaps in raster data sets is easy. It provides both a user-friendly GUI and API. Now, SAGA GIS is a powerhouse because it delivers a fast-growing set of geoscientific methods to the geoscientific community.Įnable multiple windows to lay out all your analysis (map, histograms, scatter plots, attributes, etc). It started primarily for terrain analysis such as hillshading, watershed extraction, and visibility analysis.

SAGA GIS (System for Automated Geoscientific Analyses) is one of the classics in the world of free GIS software. REVIEW: WhiteBox GAT – Geospatial Analysis Toolbox (Review) Get more useful knowledge from the Whitebox GAT Open Source Blog.

I find it amazing this free GIS software almost goes unheard of in the GIS industry. But overall Whitebox GAT is solid with over 410 tools to clip, convert, analyze, manage, buffer and extract geospatial information. The cartographic mapping software tools are primitive compared to QGIS.

But you may need a Java update to go in full throttle though. For example, LAS to shapefile is an insanely useful tool. Where it shines is LIDAR! With no barriers, Whitebox GAT is the swiss-army knife of LiDAR data. Whitebox GAT is really a full-blown open-access GIS and remote sensing software package.
It actually replaced Terrain Analysis System (TAS) – a tool for hydro-geomorphic applications. There’s a hydrology theme around Whitebox GAT. Unbelievably, Whitebox GAT has only been around since 2009 because it feels so fine-tuned when you see it in action. For this, UKPN needed a solution which would automatically generate the ‘maps’ customers were requesting, sending results in a matter of minutes.Yes, Whitebox GAT (Geospatial Analysis Toolbox) is #4 on the list of open source, free GIS software. The company felt this would improve customer service and reduce the number of asset strikes. Instead it wanted to respond to each enquiry online, making the process much quicker. UKPN wanted to move away from this more traditional way of providing asset plans via print.
However, this way of operating was creating huge backlogs, which meant that the team often had to work on weekends and evenings to supply customers with the information they needed in an appropriate timeframe. Due to the sheer number of customer requests, not only was the printing machine one of the most important pieces of technology in the office, but it also was one person’s job to fold the printed plans for their entire shift.
Both teams were large, employing up to seven people at any one time. UKPN had two plan provision departments, both of which were responsible for answering customer requests and printing out plans of UKPN’s underground network. I n 2019, UKPN was receiving up to 70,000 enquiries per month through LSB UD, which is a 250 percent increase year on year since it first became a Member.
