The Elevation Value in ControlGRIS Does Not Match the Respective Evaluation Value in SpatGRIS: A Critical Analysis

In the realm of spatial analysis and Geographic Information Systems (GIS), accuracy and precision are paramount. The discrepancy between the elevation values in ControlGRIS and SpatGRIS has sparked concern among users, highlighting the need for a thorough investigation. This article delves into the issue, providing a step-by-step guide to reproduce the problem, an analysis of the current bug behavior, and an examination of the expected correct behavior. Furthermore, possible fixes and additional comments from the community are discussed.

The elevation value in ControlGRIS does not match the respective evaluation value in SpatGRIS. This discrepancy has significant implications for users relying on these applications for spatial analysis and decision-making.

To reproduce the issue, follow these steps:

Launch SpatGRIS: Open the SpatGRIS application and ensure it is functioning correctly.
Launch ControlGRIS: Launch the ControlGRIS application and verify that it is operational.
Move a Source to the Same Position as a Speaker in ControlGRIS: In ControlGRIS, attempt to move a source to the same position as a speaker. This will help identify any discrepancies in elevation values.
Open the Speaker Edition View in SpatGRIS: In SpatGRIS, open the Speaker Edition view to compare the elevation values.
Compare the Elevation Values: Compare the elevation values in both applications to identify any discrepancies.

The current bug behavior is characterized by a discrepancy in elevation values between ControlGRIS and SpatGRIS. Specifically, the elevation value in SpatGRIS is slightly different from the value in ControlGRIS, with a different order of magnitude. For example, the elevation value in ControlGRIS may be 0.34, while the value in SpatGRIS is 30.0.

The expected correct behavior is that the scale of measurement should be equivalent in both applications. Additionally, the position should match exactly, with no discrepancies in elevation values.

The frequency of occurrence of this behavior is 100%, indicating that the issue is consistent and reproducible.

A screenshot of the issue is provided below:

Several possible fixes have been proposed to address the issue:

Re-evaluate the Coordinate System: Re-evaluate the coordinate system used in both applications to ensure that it is consistent and accurate.
Update the Elevation Values: Update the elevation values in SpatGRIS to match the values in ControlGRIS.
Implement a Conversion Factor: Implement a conversion factor to account for the discrepancy in elevation values.
