Hi, I have some maps from Jordan I would like to publish. The original data I got from Jordan is shp. The *.prj file is included. I also edit the MapInfo.prj file so it shows the Old Palestine Grid.

I did at the following to the Mapinfo.prj file.

Palestine 1923
central meridian: 31.180627
latitude of origin: 34.314202
scale factor: 1.0
false easting: 170251.55 m
false northing: 126867.909 m

Like "Old Palestine Grid", 30,60,7,31.180627,34.314202,170251.555,126867.909

Now my map doesn’t show at the right place I looks like the north is ok but the east is placed in Algeria (about 3.500 km to the west) Se image

This is the *.prj file which is included with the shp file. I did try my own as well the included *.prj It still make no sense. I added a shp file also

PROCS["Palestine_1923_Palestine_Grid",GEOGCS["GCS_Palestine_1923",DATUM["D_Palestine_1923",SPHERD["Clarke_1880_Benoit",6378300.79,293.466234571]],PRIMEM["Greenwich",0.0],UNIT["Degree",0.0174532925199433]],PROJECTION["Cassini"],PARAMETER["False_Easting",170251.555],PARAMETER["False_Northing",126867.909],PARAMETER["Central_Meridian",35.21208055555556],PARAMETER["Scale_Factor",1.0],PARAMETER["Latitude_Of_Origin",31.73409694444445],UNIT["Meter",1.0]]

Hi,

Where did 31.180627 and 34.314202 come from? They are not part of your PRJ.

You may also notice your pin in Algeria matches Greenwich, just a bit further to the South.

Hi Uffe,

I got the it from the internet where else ;) I can can see there's an error so i edit it to

"Palestine Grid", 30,60,7,31.73409694444445,35.21208055555556,170251.555,126867.909

Now I'm having a problem with the datum I used (60, Narhwan, Saudi Arabian, Clarke 1880) but maybe it should be another? Is it possible to add a new datum at all? Here's what ARC-GIS comes up with se below for "Datum: D_Palestine_1923"

If i use Universal translator the data ended up at the coast of Turkey..

Hi Tony,

I don't think it's possible to add a new datum to MapInfo and I don't think its part of th exsisting

list of datum's used in Mapinfo.

Hi,

Look up "Defining Custom Datums" in the documentation. 999 and 9999 is the keyword here.

But for projections you are stuck with the ones already implemented.
