Good day all. I need some assistance. I need ideas on how to calculate /run a procedure to check for environmental legal requirements, 100% inside SAGA. PROBLEM:. Law that defines total protection / no human presence for mountain areas which fall into the following 3 parameters ( X AND Y AND Z, at the same time, which are: 1) slope > 45 % 2) 100m or more from saddle point of the defining mountain sector - see item 3, below 3) mountain sector defined by the lowest point of saddle of a 500m radius...

Hi there. I successfully ran Symmetrical Difference & Difference tools both yielding same results (should they?) but what is bothering me is that the attributes table generated are in both cases EXACTLY the same value and the bigger layer from which I want to subtract. Let me explain: I have layer A of a national park 3km buffer. I subtract from it the national park layer B. Layer C is then created with the right polygon BUT the area inside the attributes is no (A - B) but rather A! SAGA is proving...

Hi. Is this a common problem related to algorithm or something or a glitch? I have noticed that creating buffers takes ages. No exaggeration.... I ran the same layer on QGIS and the very same result took 13 secs while on SAGA the whole thing freezes and the tool takes about 8 min.... one time was so bad i had to crash it after going for a snack and coming back to a still running routine LOL One single polygon layer.... Any one else has had similar problem or noticed similar ordeal? cheers PS: on...

Hello all. I am a novice, so please bear with me, mates! I have been enjoying SAGA so much even though I just started, enough to almost completely ditch QGIS, but I have been dealing with the difficulty of tweaking and handling tables and alphanumerical data. SO, trying to learn RECLASSIFICATION from this link: https://sagatutorials.wordpress.com/reclassification/ I was able to perform every thing UP TO the point where I could not at any cost locate the drop-down menu option "Create Lookup Table"...
