We have been using QGIS since around 2020 and have been working on many GIS projects during this time. However, we recently discovered that the data we have collected and analyzed seems to be in a different coordinate system. Upon comparing the projection details in the .prj files, we noticed that they are nearly identical except of the name of the coordinate system, but we are unsure if there has been a change in naming due to updates of the software. Could you please share any information on this issue if you have? </p><p style="margin: 0px; padding: 0px; border: 0px; outline: 0px; font-variant-numeric: inherit; font-variant-east-asian: inherit; font-variant-alternates: inherit; font-variant-position: inherit; font-stretch: inherit; font-size: 10pt; line-height: 20px; font-optical-sizing: inherit; font-size-adjust: inherit; font-kerning: inherit; font-feature-settings: inherit; font-variation-settings: inherit; vertical-align: baseline; min-height: 20px; color: rgb(34, 34, 34); font-family: 돋움;"> </p><p style="margin: 0px; padding: 0px; border: 0px; outline: 0px; font-variant-numeric: inherit; font-variant-east-asian: inherit; font-variant-alternates: inherit; font-variant-position: inherit; font-stretch: inherit; font-size: 10pt; line-height: 20px; font-optical-sizing: inherit; font-size-adjust: inherit; font-kerning: inherit; font-feature-settings: inherit; font-variation-settings: inherit; vertical-align: baseline; min-height: 20px; color: rgb(34, 34, 34); font-family: 돋움;">Our specific question is whether "KGD200_Central_Belt_2010" from a new version and "Korea_2000_Korea_Central_Bult_2010" from an old version are different. We have been using the EPSG:5186 system all the time.
