I have previously written about automatically edge detecting. Using OpenCV is a nice way of quickly running the edge detect and getting some information back about the image. You can read about the Canny edge detection algorithm here Here is how Wikipedia details the process of the canny edge detection (if you didn’t click the… Read More »Reclassify and Numpy
Template matching is a useful technique. Some common uses include manufacturing as a part of quality control, a way to navigate a mobile robot, or as a way to detect edges in images. But can techniques such as these be useful for data captured from satellites? I am especially interested here in Optical data, but… Read More »Template matching with Earth Observation Data
You know about planet (formerly Planet Labs), right? Their aim is to map every part of the Earth’s surface everyday using their Dove satellites. One Pixel for every area every day. Temporal data at its best! If you get an image every day and you want to monitor it (change being the obvious reason) a… Read More »Edge detecting with Planet API
Last week I attended the ESRI Petroleum user group in London. I think just over 200 people attended. I missed last year’s event but I have been present at this regular event many times in the past. Many thanks to the organisers – they do an incredible job. Pleasingly, there were plenty of Earth Observation… Read More »GIS Petroleum User Group
