Interpolate your data

Using a dataset, defined by points, it is possible to make interpolations and obtain surface representations that prove useful for visualising the phenomena.  This script has been written to allow you an 'Inverse Distance Weighted' interpolation on your data set.

If you try this application, you have to be careful about important aspects resulting for the interpolation process itself. The application allows you to automate the interpolation of your data set, with pre-defined parameters and method (Inverse Distance Weighted): it will give very different results depending on the size of your file (number of points), the spatial repartition, the parameter analysed etc. The results could be very far away from the reality... and you should use the result with care!

To perform interpolation on your request results (cf. Search IDOD), choose one of the ARCIMS viewers then from the end of the following page, click on "Interpolate your data set".

Interpolated maps of salinity and temperature:

This script shows you the situation of temperature and salinity for a single campaign. The result is an interpolated surface of temperature or salinity, pre-processed by the IDOD team, using a complex interpolation method (kriging). An isolines layer based on the variance overlaps this image.

The map can be downloaded as a grid of values and as a shapefile of variance.

The list of available maps is updated each month, with new maps of recent campaigns. At a later stage, other variables will also be analysed and interpolated.

Extract a DTM (Bathymetric Digital Terrain Model)

You have the possibility of extracting a subset from a pre-processed bathymetry model.

You will see the result immediately but you can also download it in 'grid ArcINFO', 'Binary Raster' and 'ASCII Raster' formats.

Extract a profile

This script allows you to extract a profile along a defined track. You can choose the layer you want to make a profile from: either one of your previous requests, or a pre-interpolated layer of salinity, temperature, or bathymetry.

The results of the request can be seen immediately or can be downloaded in graphical format, Distance-Z value table, grid ArcINFO and shapefile of the track.
