To illustrate this process in another way, create the following coordinate system using these parameters by adding a new entry to the MAPINFOW.PRJ file:
Parameter Type | Entry | Description |
---|---|---|
Name |
"Equidistant Conic Plus" |
Name of the new coordinate system |
Projection Type |
6, |
Equidistant Conic |
Datum |
74, |
(NAD 83) |
Units |
7, |

Origin Longitude |
-90.5, |
90×30¢W |
Origin Latitude |
30, |
30×N, |
Standard Parallel 1 |
10.33333, |
10×20¢N |
Standard Parallel 2 |
50, |
50×N |
False Easting |
10000000, |
10,000,000 m |
False Northing |
500000 |
500,000 m |
- Open MAPINFOW.PRJ in a text editor or word processor.
- Go to the Equidistant Conic section and add a new line.
- Type the name of your new coordinate system in quotes, followed by a comma.
- Enter the following information to represent your coordinate system:
6, 74, 7, -90.5, 30, 10.33333, 50, 10000000, 500000
- Save your edited MAPINFOW.PRJ file.
You can use your custom coordinate system just as you would use any of the coordinate systems that come with MapInfo Pro.
There are other ways you can edit this file. To shorten the list, remove coordinate systems from the file. You can also change the names, change group headings and reorder the file to suit your needs.
