How to change grid scale in Surfer 10
By rahmansunbeam,
I have been trying hard to find out the way of getting good image from Golden Software Surfer 10, but there is a problem. How to change the default x and y grid scale? The default shows the area in inches, I want it in degree-minute-second. See the image, I want those numbers in degree-minute-second. Is this possible?
Raster to polygon conversion
By Lurker,
Hello all, just want to share and maybe little help here
I maka slope classification using ArcGIS, that result in raster format :azn:
the real problem is to make it shapefile which is vector file (polygon)
Right now, from what I know, the only way to make smooth and good slope polygon from raster is by manually digitize it :lipsrsealed: which is really annoying if you face large area :shocked:
I try to directly convert it via raster to polygon conversion, which lead to really bad pol

By veegee,
Hi all,
Is there any better procedure to georeference shape-files (which should not warp after doing it by spatial adjustment in arcmap)
thanks in advance.

Hello folks! I am trying to use the Lyzenga Algorithm for estimating the depth of water in shallower areas, probably depths under 8-10 meters of lakes. First of all, how accurate is this algorithm in practice? Secondly, lets say i have the band values. can someone explain me how to retrieve those depths? I am following the "Lyzenga Algorithm for Shallow Water Mapping Using Multispectral Sentinel-2 Imageries in Gili Noko Waters" paper, but there are 3 steps of getting NDWIs, NDCIs and after filtering the Sun Glint Correction, then it finally comes to the depth calculating. it end ups in a formula of following: 𝑧 = 28.32 ∗ 𝑋1 − 36.25 ∗ 𝑋2 + 9.42 ∗ 𝑋3 + 16.35 x1 , x2, x3 are RGB values respectively. What do you guys think? can i just apply this formula ? if not, what is the purpose of all the previous steps, and will they change the rgb values anyways? -
