Ecognition Tutorial How To Carry OutAnswered Assumed Answered Assets for segmenting SentineI-1 SAR information in eCognition Query inquired by Sarah Siénaert on Jul 13, 2020 Most recent answer back on Jul 27, 2020 by Sarah Sienaert Like Display 0 Loves 0 Remark 2 Hello, I was looking for resources to assist me understand how to carry out an item based image analysis (segmentation) of SentineI-1 SAR imagery in eCognition.All the learning assets I have arrive across to date focus on optical symbolism.Many thanks, Sarah Zero one else has this query Mark as believed answered Results Presence: Mapping and GIS Options Local community 47 Sights Last improved on Jul 13, 2020 11:41 Was Tags: ecognition Articles tagged with ecognition sar Articles marked with sar sentinel-1 Articles tagged with sentinel-1 This content material has become designated as last. Present 2 remarks 2 Response Name Email Address Web site Address Title (Required) E-mail Tackle (Required, will not be published) Website Address Orlando Weise Jul 23, 2020 11:21 PM Mark Correct Correct Answer Hello there Sarah, You are right, radar data are not often utilized in this circumstance but it functions: If you convert you 1632 little bit data into 8 little bit data, simply for the ségmentation, you will discover that you can make use of the radar data in the same method like optical data. The trick is usually to create temporary levels as result of the layer histogram alteration therefore that you nevertheless possess the primary sentinel-1 data in the eCognition project (for additional analysis). You can convert the input information into 8 little bit using layer arithmetics. I wasnt capable to open up the documents in the propagated files, but I did successfully convert my levels to 8 little bit using the level arithmetics protocol. However, its not really clear to me how I make use of the 8-little bit levels to execute the segmentation ás I can distinguish even much less with the 8-bit levels than I couId with the 32-bit layers. I have experimented with various layer combinations in the see configurations, but I see a solid wedge of color no matter which combination of 8-little bit levels I try. Where are I heading wrong Its worth mentioning that Im not really intending to section the entire scene. I have a face mask filled with one kind of land cover (a sapling crop) and Im looking to distinguish different age group courses and the presenceabsence of flooding within that one tree bounty. Im not really seeking advice on how to make use of a thematic coating to limit the segmentation, I understand how to perform this. I point out it so you are usually aware that the distinctions among my lessons are much more subtle than trying to distinguish among buildings, roads, rivers, crops etc. Sarah Like Show 0 Likes 0 Actions Related Content material Retrieving data.
