This channel is dedicated to videos produced by Kevin McGarigal
LandEco Lightning Talks are a series of short presentations (10-20 minutes) on landscape ecology topics. They are best viewed in order within each labeled mini series, beginning with the Landscape Concept series. These talks are designed as an educational series for all audiences, but are intended primarily to serve the professional land conservation community.
NASP videos are a couple of training videos on the use of R and Fragstats software programs for students in the National Advanced Silviculture Program and were designed as pre-work for an intensive 2-week course on landscape ecology.

how class description file (.fcd) and Edge Contrast (.fsg) file was created?
Mr McGarigal, I´m have been tryint to download de RFrag.zip for R and it doesn´t exist. Can you share ir wiht me please?
Thank you very much. But when I pratice with my data has three class, the result always the result always returns 4 layers (3 class I need and plus 999 class). How can I fix it?
Why are there no more lectures on landscape ecology?
Well, I do have several lectures posted on this channel in this playlist, but I have not pursued producing any additional lectuers until I see that my LandEco Lightning talk series is popular enough to warrant the effort. Cheers.
@@mcgarigal_landeco3663 Thank you for your kind words and appreciation. "Yes, indeed, those three lectures hold great significance and offer comprehensive insights into landscape ecology. I have successfully extracted the subtitles of all three lectures using specialized software and converted them into a Microsoft Word document."
My name is Tariq and I am currently a PhD student at Beijing Forestry University in forestry management. Nice to meet you Sir.
Thank you! The video provides well-organized and clear information!
You are welcome!
Thank you, I've been using your papers in bibliographic references since I was in my geography degree here in Brazil and now in my geoprocessing technology studies. I use the Fragstat software as well.
Glad to hear it Manoel!
Fragstats must and should be further improved in terms of its GUI. More specifically, it should finally get its own window for data visualization and manipulation. And secondly, Fragstats needs to nurse its permanent website, which recently lost. Fragstats as the main software and the progenitor of the area landscape metric deserves it all. Also, two great software that use Fragstat's metrics are: VecLI ( it's realistically another but improved Fragstats) is new and the best landscape metrics software for vector data with 200 + metrics of Fragstats software, with GUI and window for visualization and manipulation vector data (shp files)..The whole process is automated and the software is completely free. landscapeXShiny is one new app for package " landscapemetrics" in R. For this you do not need to know how to work in the command line interface in the R environment.
not able to reclassify the map output..it is showing only the lower and the high values as well as an exceptional error is also there while running the metrices saying " assertion failed expression: m_BatchSIZE > 0"
Not sure what exactly you are referring to with regards to reclassifying the map output. I assume you are referring to creating the categorical input landscape? If so, this is a GIS operation and not within the scope of fragstats. I suspect that you might have tried to input a raster that was not coded as in integer reflecting the classes? This could result in the outputs you are reporting.
how will I export the fragstats result table to Arc Gis and add it to the attribute table of the same tif. image
This is a GIS operation and not something fragstats was designed to automate. However, the Join operation can be used to join the class-level tabular fragstats output to the input raster so long as you have a common id field. At the patch level fragstats can generate a patch id raster that can be joined with the patch-level tabular fragstats output, again, using the Join function in ArcGIS on a common id field. Joining the landscape output id not possible or meaningful.
How do you generate file for 'Edge Contrast'? Class descriptor and Edge contrast do not generate automatically. Please elaborate the matter.
Sorry, but it is up to you to create the weights file with the format I described, and there are many ways to do this with different software. Creating the weights files is not something fragstats was designed to do. Personally, I have used custom scripts in R to create these files specific to my applications.
Im writing to you all the way from Sweden. Im a masters student In hydrology and hydrogeoly at Stockholm University and currently working on my Master thesis. I will use Fragstats and found your two youtube videos.
OMG!! YOU ARE THE AUTHOR OF THE FRAGSTATS HELP!!! THAT EXPLAINS EVERYTHING!! PLEASE MAKE MORE VIDEOS, THEY ARE REALLY HIGH HIGH QUALITY
Thank you
best explanation ever! Really good instructor you are!!! thank you!!! <3
Thank you
When adding a GeoTIFF file to the Fragstats, the cell size always is 0. I don't know how to change this cell size, and the analysis result was empty. Can you please help me, thanks!
Just got it! It was because of the "Geographic coordinate" that lead to a 0 cell size. I projected the raster into a "Project coordinate" system and the problem solved!
Hi there! Please, would you suggest to me some link or tutorial and I need to learn habitat connectivity for wildlife using fragstat but unfortunately, there is no detailed visual information. Im super new to GIS! I am thankful to you in advance.
Sounds like you have a problem with the format of the input raster and thus fragstats is not able to analyze it. This is something you must resolve on the GIS side before inputting to fragstats.
How we can find the link to the training data for this session. you have mentioned that I will provide you by email.
Sorry, but this video was created for a very specific user audience and thus, unfortunately, those files are not available for public distribution.
Good job.
Thank you.
Thank you Sir, Would you like to provide me a link to download the files so that I can learn this software properly. how class description file (.fcd) and Edge Contrast (.fsg) file was created?

Good Morning Sir sir we request you to post more videos on the Fragstats software. sir please share if any upcoming training for the fragstats software is coming up so that we can join the same. and thank you so much sir for such an informative lecture.
Sorry, but I have not prepared any additional videos on the software, but I do encourage you to work through the tutorials that are available on github at github.com/kmcgarigal/Fragstats
Thank you very much! This was very useful!
Glad it was helpful.
Thank you sir, can you tell me how to set the edge contrast/similarity/edge depth value between types?
Sorry, but this is application-specific and depends on objectives, available data, and many other considerations. The help files show you how to format the weight files, but it is up to you to figure out what the weights should be.
