saga gis and swath profile
« on: October 17, 2019, 06:32:36 am »
Hi,

I was trying out saga gis, and you can plot surfer grid maps, plus do swath (wide line average) profiles

saga gis is here

http://www.saga-gis.org/en/index.html

Here's an image of a map plotted using saga gis, and printed as pdf



Here's a screenshot showing the swath profile



The data is averaged between the two lines paralleling the central line.

The swath profile is interactive, you click on the two points with left mouse button, then right click - and graph and table update

If anyone's interested I can explain how to load a map, and create a swath profile

Ben

Hi Ben,
Never saw these GIS tools before, but good to know. Thanks.

But it is interesting, isn't it?  That we microscopists utilize GIS tools designed for kilometer scales, and use them at micrometer scales.  :D    Only a difference in "mapping" scale of 10^9!

As you probably know, the Surfer software integrated with CalcImage for output, is also designed for GIS.  And just in case anyone doesn't know, Golden Software offers a "student" license for $50 for one year if reducing costs for students is an issue:

The only stupid question is the one not asked!
