I recently carried out a surface water sampling of a pond and I am looking to create a contour plot of all my stations with X-(longitude), Y- (latitude) and Z- (Nitrates) in ODV. I have created a .txt file for all my variables and imported it into ODV along with the shapefile of the study area. However I keeping getting station dots enclosed in the study area and not a contour/colour map.
Clearly there is a step (or steps) I am missing - but I have no idea what that step might be?
If anyone has some experience with contour plots, I would really appreciate any advice?
Hi Raphael,
I was able to create a basic contour plot of your data (attached) by the following steps:
Hi Matthew,
Is there any way to get around this without inverting the latitude and longitude?. If not, do you know of any other software that I can use to do this. I have tried using GIS but the pixel surface is not very sharp
Thanks.
Hi Raphael,
I'm not sure unfortunately - but I think that you might get a quicker response at the ODV forum than here: http://odv.awi.de/en/odv_forum/
Other software - personally, I would use MATLAB for this, but if you have not used it (or at least other coding languages) before then it's quite a steep learning curve to make a plot like this
Good luck!
Matthew
Yea I have looked into using MATLAB and R but Its kind of way higher than my level and time consuming.
Thanks for your help!
Hi Raphael
Sorry for this late answer. But you can easily modify your graph :
- Go on your surface map window
- put the pointer on the map
- right clik and go on x-variables : you can change the variable. choise longitude instead of latitude.
- do the same thing with y-variable : latitude instead of longitude.
I hope that can help you.
