[Qgis-user] Geographic Coordinate warning systems

Good afternoon everyone,

I ask help for the following:

I want to send a shapefile of type line, which was created with AutoCAD Map
3D, and has the coordinates of the IGP (negative), for the coordinates of
IGEOE (military).

When opening the Qgis the first thing i do is insert a shapefile (County)
with the coordinates:

"+ Proj = tmerc lat_0 = + + lon_0 =- 39.66666666666666 8.131906111111112 + k
= 1 + x_0 = 200180.598 + y_0 = 299913.01 + ellps = intl + units = m +
no_defs (ESRI), which are the coordinates of IGEO (ESRI)

After I insert in the shapefile Qgis I want to pass the coordinates of IGEO
(ESRI), and use as reference the coordinates of the previous theme (county)

Put the subject in editing and use the plugin Affine (rotation, translation,
scale?

Choose the option "Whole layer

Translation x: 200 000 - Translation y: 300 000

Run

Then do a save as

I give a name to shapefile

The encoding is: ISO8859-1

CRS: I say it is equal to the shapefile used as reference (county)

OK

Menu 'Vector'

Data Management Tools - Export to new projection

And I choose the coordinates of the subject county, burn to a folder, but
when I try to open the shapefile in ArcMap 9.2 this message appears:

(Geographic Coordinate warning systems): International 1909 (Hayford)

What am I doing wrong?

This was only discovered today, there was some change in Qgis causing this
message? Since last week, I used the same procedures for other shapes, which
were opened in ArcMap 9.2 and did not show any such message.


Thank you for your help.
