Overview
The iShare Spatial Data Warehouse (SDW) can hold data in different projections although it is better to translate all added datasets to the EPSG 27700 format (which is the projected coordinate system for the United Kingdom (UK)) for consistency and ease of use in QGIS, etc. If you have Shape files with different projections that you wish to load into your SDW this can be done by converting the data as you load it, but first you need to find its current projection.
Step-by-step guide
The first step is to find out the current EPSG of the Shape file you wish to load and this can be done using the ogrinfo command e.g. ogrinfo -al -so Shape_file_name.shp.
Open a Command window and navigate to the OGR folder e.g.
...
This gives a summary of the layer's spatial information including its EPSG ID. There are often several lines that have this ID but it is the very bottom in the list that is needed i.e. 4326 in the above example.
Open iShare Studio and under Workflow expand the Jobs node.
Select Unassigned Tasks and create a New Task > Spatial Data Transformation Task
Enter a unique Name for your Task.
Select your Source Data (your Shape File) and Output the SDW.
Under the Options UNTICK Projection as British National Grid
Tick Expert mode
Now in the Additional Parameters box add the following replacing your_EPSG_ID with the EPSG ID from running the above ogrinfo command:

Run the Task to make sure it works
Save the Task if you want to keep it for future useNow see Import Layers with different Projections on how to load the data.
