can you explain more Alejandro and I will look it up.

@@stuartehamiltongmail thank you

It should be meters if in the correct projection.

sure

Please did you figure it out? Having the same problem

Ensure you are working in the relevant UTM zone

Seems like you need to have python installed in the correct directory, use the OSGEO4w version of QGIS and this should help

Have you tried searching for the plugin on the web? I just worked them out one-by-one

Fragstats is the full suite of landscape tools available at www.umass.edu/landeco/research/fragstats/fragstats.html. LECOS is a smaller suite for QGIS based on fragstats. plugins.qgis.org/plugins/LecoS/

This was a grid mission. Purpose is to show some data and the steps

Use the OSGEO4W Install of QGIS

@@stuartehamiltongmail This error appears "ERROR: Could not find a version that satisfies the requirement pil (from versions: none) ERROR: No matching distribution found for pil" I try with pip install pillow and install, but it doesn't solve the problem and it doesn't let me use lecos, helpp :(

Thanks Jiake

No it will not.

I spend quite some time close to Migingo island but have never been on the island. I see it is currently listed as the 3rd most densely populated island in the world! www.worldatlas.com/articles/the-world-s-most-densely-populated-islands.html. What do you need?

Yes, look for a free app called Skype Toad

No it is quite expensive, this video can all be done in QGIS for free.

right click on the layer and repair data source and point it to where you downloaded the data

yep, rainfall and a depression that has built over time, not a rift-valley lake. quite shallow, just a natural depression with limited outflow. This is why the level changes so drastically in short periods. If you mean the data that is here dataverse.harvard.edu/dataverse/LakeVicFish and the lake source (furthest upflow) is in Burundi. vimeo.com/210437103

@@stuartehamiltongmail what caused the depression downwarpping ? What is at the bottom that causes the springs along the river Nile after it leaves lake Victoria ? Any relation to volcanic activity ? Any idea where the sources from the mountains used to flow before the lake ? How far back in time would you place it ? So much amazes me about the lake. Would a meteor create that depression? I saw some divers down there on KZbin m.kzbin.info/www/bejne/kIrVZWBthrmgmas Made me wonder what a submersible of some sort would find.

@@worldwide1856743 think of it as a shallow bowl. It was dry in the last 15000 years. It is a rain fed shallow lake. I suspect the earlier flow would have followed the Albertine Nile north.

I think it is best thought of as numerous sources. None are really major rivers in their own right.

I never used them from google engine, sorry. I get them direct from ESA. scihub.copernicus.eu/

since SAGA implemented this algorithm. the threshold describes the minimum Strahler order to initialize a channel. Here, the Strahler order is computed as follows: first, the Strahler Order grid is initialized with 0. Then, the DEM is processed top-down and for each cell it is evaluated which cells flow into it and which Strahler order they have. If two "streams" (here cells) of the same order flow into the currently processed cell, the cell is given a number that is one higher. If cells with different stream orders flow into the currently processed cell, the cell is given the higher of the two numbers. After the whole DEM is processed, you have a grid with stream orders that can be used to apply the threshold for channel initiation. Negative and zero cell values can be explained as follows: after all processing is done, just before tool execution stops, the order grid is processed once more by adding the following term to each grid cell: (1 - threshold) This assigns each cell an order, with the summit and ridges having the lowest order. I don't remember how this was implemented in SAGA 2.1.2, but in recent versions the NoData value range of the Stream Order grid is set to the "negative to zero" value range in order to mask these values in a map view.

Thanks Assoul
