Pic1_not recls Pic2_reclas ... View more

well, I tried in this way: I extracted by mask the river raster, reclassified it with a value of 0; then I reclassified the slope raster (the main one, I mean) with values starting from 2 up to 10 and merged both into a new raster. Afterwards, I used the path distance tool (in order to obtain the cost surface, the back link raster and using also the tobler's function). In the end I applied the cost path tool. I worked, the river is used as main path to reach the other points. But I have two questions: could it be considered correct this method? Since I gave an higher value to the main slope (i.e. reclassifying it), could the result be wrong (see pic1 not reclassified, pic2 reclassified)? ... View more

Thank you for replying me... Well, the river is a polyline shp, therefore I could convert it in a raster and then assign the value by using reclassify tool or mapalgebra tool, is it correct? Thanks ... View more

Thank you, I'll keep in mind! ... View more

Here the pics... I tried the focal statistical tool choosing as parameters 3x3, 5x5 and 7x7. Therefore, the 1st pic is the DTM without any tool applied (Low : -17,8801; High : 927,206), the 2nd is the DTM with 3x3 rectangle applied (Low : -16,9978; High : 927,156), the 3rd with 5x5 (Low : -15,4011; High : 927,086) and the 4th one with 7x7 (Low : -13,0596; ). Anyway, the changing is visible yet it doesn't look like very big. ... View more

Thank you, Dan... sorry for the question, maybe silly, yet is it work also with the slope in percentage or it has to be in degrees? Moreover, if I chose instead of 3x3 a rectangle 5x5 or 7x7, what would it change? I mean, just the size or I could see a more significant smoothing result. I am asking to you because I didn't find on internet a specific info about this. Thank you ... View more

So, actually the major part of the land, in which I would apply the buffer, has not a huge elevation, it is an hilly terrain. Therefore, the buffer 3d couldn't be the best choice, considering that I should use a radius with a km length ... View more

Well, I checked and I have not a buf_3D, so I guess I will have to try again the code; moreover, if I switch one all the layers created by the code I obtain that just only a buffer has specific info in its attribute table (as you can see in the pics; 1-general, 2-detail, 3-detail with attribute table). Therefore, I could consider it a mistake too. ... View more

Thanks.... I tried too, changing the pix size in 8. The code worked without any problems, yet the result is still the same which means that it didn't show any changing as in yours. Moreover, the previous result overlapped the new one perfectly. I attached two pics: the red line is the new datum, while the black line the old one. ... View more

So, this discrepancy between the visual expectation and the reality to what is due? ... View more

Yes, my coordinate system is projected and max distance is 3000mt. I attached the sample files (on top) ... View more

here I can't upload the data, because they exceed the uploading limit... So, the DTM resolution is 8mt, actually I copied your code changing the folder locations and max distance (because all the rest seems correct, at least) ... View more
