In proj4js.js

var datumDef=Proj4js.Datum[this.datumCode]
if(datumDef)
{
    this.datum_params=datumDef.towgs84.split(',');
    ....
}


if the datumCode is NAD27(CA-I), the datumDef will not contain a property named towgs84. So, to fix this problem or the workaround of this defect is add "&& datumDef.towgs84" to the if clause to make sure towgs84 is included in datumDef.

Hi Mike,

Could you review my solution and submit it if there's no problem? Since I can only can the compressed version of proj4js

Regards,
Arthur

Milestone: Future2.0
Status: newassigned

this was fixed in a later version of proj4js. I will update to the most recent version.

fixed in trunk and 2.0 branch, should this be applied to the adsk/2.2gp branch?

comment:5 by chrisclaydon, 12 years ago

The 2.2gp branch should not be updated to the latest version of proj4js. I'll modify the existing version of proj4js-compressed.js with this specific fix.
