MATLAB-based software for topographic analysis
On June 2-3, we held an online EGU webinar about TopoToolbox. The webinar featured basic and more advanced examples of terrain analysis using the MATLAB and Python version of TopoToolbox. In addition, we discussed the architecture of TopoToolbox 3, introduced the TopoToolbox Gallery and demonstrated how the community can contribute to its further development. If […]
This is a PhD advertisement by Paolo Ballato, Department of Science, Roma Tre University, Rome, Italy. For any inquires, please contact him paolo.ballato@uniroma3.it We are seeking a highly motivated PhD candidate to join a research project investigating the history of water and climate on early Mars. The project combines the analysis of satellite imagery, digital […]
TopoToolbox has evolved during the last 2.5 years quite tremendously. Most visible to most of you may be that our terrain analysis software, which has hitherto been restricted to MATLAB users, is now available in Python, and an R version and a QGIS plugin are growing. Under the hood, there has been much more going […]
Dear TopoToolboxers, I am delighted to inform you about an upcoming event: the EGU webinar on TopoToolbox. The event comprises two workshops on June 2. and 3., each between 16:00 and 18:00 CEST. Please check the official announcement here and here and please note that you may have to register separately for each day. In […]
How about if you could easily present your TopoToolbox code, results and entire studies to others? The TopoToolbox GitHub organisation now has a new feature: The TopoToolbox Gallery. This growing repository of notebooks written in Python or MATLAB has been developed by Will Kearney and is there to enable researchers to showcase self-contained scripts. The […]
In my last post, I showed one possible way to calculate basin width. In summary, the issue is to calculate the maximum width of a region (the rasterized drainage basin) perpendicular to a line. In our case, this is the straight line connecting the outlet to the point farthest away in the basin. Rarely, this […]
Edit on 31.1. to correct a bug in the calculation. Fred recently commented on one of my posts on calculating distances in drainage basins. His question is I would like to calculate the Basin Shape index (BS). Bs is expressed as: Bs = Bl/Bw, where Bl is the length of a basin measured from the […]
readopentopo is one of my favorite tools in TopoToolbox. It enables access to the global, medium resolution DEMs hosted by OpenTopography. All you need is a key to the OpenTopography API which you obtain free of charge after registering. There are different ways to use readopentopo. You can provide an extent by supplying an existing […]
edit: The event has been moved to Feb 24, a day earlier than announced previously. The BankfullMapper is a MATLAB and TopoToolbox-based software that let’s you delineate the height and extent of bankfull flow based on high-resolution topographic data. There are two blog posts that provide details and examples (BankfullMapper: a semi-automated MATLAB tool on […]
