From Version 5.6.2. You may select a Projection for your Map Source by picking an entry from the list. There is a default Projection that is configured via the iShare Settings on the General tab under the Web heading.
If you need to add a different Projection then you will need to manually edit the D:\iShareData\Astun\_MapServerConfig\projections\epsg file in a Text Editor such as Notepad++. The entries must be formatted correctly to display in the list correctly e.g. for BNG
# OSGB 1936 / British National Grid <27700> +title=British National Grid +proj=tmerc +lat_0=49 +lon_0=-2 +k=0.999601 +x_0=400000 +y_0=-100000 +ellps=airy +units=m +no_defs no_defs <>
The first line is just a comment the next has the following formatting requirement:
| Code | Descrption |
|---|---|
<27700> | The SRID for the projection |
+title=British National Grid | The Title to display |
+proj=tmerc +lat_0=49 +lon_0=-2 +k=0.999601 +x_0=400000 +y_0=-100000 +ellps=airy +units=m +no_defs no_defs | The Projection definition. In order to find the correct definition for your required projection please see http://spatialreference.org/ref/ select the relevant entry and then click on the Proj4 link which will give you what you require. |
