RD Coordinaten Converter

The concept of this program is very simple: you want to convert a spreadsheet of RDX/RDY coordinates into their equivalent Latitude/Longitude values or vice versa. You can upload an Excel spreadsheet (.xls or .xlsx), Comma-delimited spreadsheet (.csv), or LibreOffice spreadsheet (.ods). The program modifies this spreadsheet and sends it right back to you with additional columns.

Before using this program, please do the following:

• The spreadsheet should have 3 columns.
  1. Name or identifier value, it does not matter what you name this column
  2. RDX value
  3. RDY value
• The first row will be treated as a 'header' row containing column names, your content should start on row 2.
• Numbers should be formatted as decimals with a (5.12453 not 5,12543).
• This program will only process 10000 values at a time
• Whatever file type you upload, you are getting an .xlsx file back

On the right, you will see two upload forms. One form will take column 2 (latitude) and column 3 (longitude) and fill in the associated RDX and RDY columns. The second form will do this conversion in reverse, taking your column 2 (RDX) and column 3 (RDY) and fill in the associated latitude and longitude values.

If a value is out of bounds, the program will insert 'NA' values. 'Out of bounds' means that the coordinates you have given fall outside of the Rijksdriehoekscoördinaten area.
