Testing the [[Waterwijzer Module]] manually is feasible, as the performed calculations are not spatial. This means for any given location, only the parameters present in that particular location are used to perform a calculation.


Testing the [[Waterwijzer Module]] manually is feasible, as the performed calculations are not spatial. This means for any given location, only the parameters present in that particular location are used to perform a calculation.
By creating a [[Project]] with controlled parameters for the [[Waterwijzer Overlay]], and comparing the results through a sample test, we have verified that the results presented in the {{software}} match the results of individual Waterwijzer queries exactly.

Input for the [[Waterwijzer Module]] is determined through a number of visible and a number of invisible features. To make it easier to maintain an overview of what parameters are configured where, its recommended to add a number of visible features to the [[3D world]] to demark the extend of specific configurations.

Testing the Waterwijzer Module manually is feasible, as the performed calculations are not spatial. This means for any given location, only the parameters present in that particular location are used to perform a calculation.

By creating a Project with controlled parameters for the Waterwijzer Overlay, and comparing the results through a sample test, we have verified that the results presented in the Tygron Platform match the results of individual Waterwijzer queries exactly.

Testing principle

The best way to approach testing the connection is to set up a Project to produce a variety of results. Those results can then be manually read out, and the same configuration can be input in the online Waterwijzer tool[1]. Because the Tygron Platform connects to the same calculation model, the same input should also lead to the same output.

Setting up the project

  • Create a new empty Project with a minimal size. By creating an empty project we have full control of the spatial data that is present.

Demarkation

A grid demarkation using the "concrete" Terrain Type.

Input for the Waterwijzer Module is determined through a number of visible and a number of invisible features. To make it easier to maintain an overview of what parameters are configured where, its recommended to add a number of visible features to the project to demark the extend of specific configurations.

Using a distinctive Terrain Type such as "Concrete", draw a grid of plots. Make each plot approximately 20m by 20m. This should easily allow a grid of 10 by 10 plots.

Groundwater

A computed high groundwater result from the Subsidence Overlay. A computed low groundwater result shown on the navigation panel.

The groundwater situation is easiest to set up by using a Subsidence Overlay. It needn't calculate, but can have its groundwater situation directly configured through Areas and Attributes so that it's set to a specific value.

Across the "rows" of the grid currently drawn-in, the low groundwater result will vary. Across the "columns" of the grid, the high groundwater result will vary.

The 3D Visualization is now divided up into a 5 by 5 grid of similar blocks, each consisting of 4 plots 20m by 20m. The blocks differ in combination of low and high groundwater level.

Terrains

A repeated pattern for the underground, 4 Terrain Types for every combination of groundwater.

Terrains, specifically underground Terrain Types, all have a specific BOFEK_ID. Multiple can be added to the project to experiment with.

  • For each block with plots with the same lowest groundwater and the same highest groundwater levels, draw the following Terrain Types in the following plots:
    • In the north-west plot, draw the underground to be "Koopveengronden op bosveen (of eutroof broekveen)", which has BOFEK_ID 101.
    • In the north-east plot, draw the underground to be "Veldpodzolgronden; grof zand", which has BOFEK_ID 320.
    • In the south-west plot, draw the underground to be "Moerige eerdgronden met een moerige bovengrond op zand", which has BOFEK_ID 203.
    • In the south-east plot, draw the underground to be "Kalkarme leek-/woudeerdgronden; klei, profielverloop 5", which has BOFEK_ID 415.
  • Add an Underground Overlay, to review the configuration of the underground Terrain Types.

There is now a matrix of varying lowest groundwater levels, highest groundwater levels, and underground types.

Crops

Crops on every plot. The selected Function is "corn", but the exact Function doesn't matter.

Crops have a BRP Code as an Attribute assigned to them as part of the process of creating a new Project. New crops created through the Editor do not yet have a default code assigned to them, so regardless of the desired crops to test with, a code must be entered manually.

Overlay

Finally, the actual Waterwijzer Overlay has to be added and configured to perform the calculations.

Results

The world now contains a checkerboard of varying results. These results can be easily checked against the online Waterwijzer tool[1]. A sample test is sufficient to validate that the results displayed/used in the Tygron Platform match the results of the online tool.

Obtaining results

Individual results can be obtained as follows.

Reading a result from the Tygron Platform

Reading a result from the online Waterwijzer tool

  • Open the online Waterwijzer tool[1].
  • As crops, select "Aardappelen" (which are potatoes, matching the crop's BRP_CODE of the Project.
  • Leave the climate ("klimaat") and weather station ("Weerstation") as-is.
  • For the underground ("bodem"), select the type matching the Terrain Type found in the plot selected in the Tygron Platform.
  • For the groundwater ("grondwater"), set the "GHG" to the high groundwater level found in the selected plot, and the "GLG" to the low groundwater level found in the selected plot.
  • Note the displayed yield losses, both the total as well as the individual components.

The results obtained in the Tygron Platform should be identical to the results obtained from the online Waterwijzer tool.

Sampled results, compared

Using the Project constructed in accordance with the preceding instructions, and the preceding instructions for retrieving comparable results, the following sampled set has been established. All inspected results match exactly.
