Thanks Even, we’ll try that.
Are there any known integer values that ESRI and EPSG conflate? If not, it
would be convenient to simply pass in an integer to a single API function and
be done with it.

Jesse,
You can use SetFromUserInput("ESRI:XXXX") . ImportFromEPSG(code) more or less
does SetFromUserInput("EPSG:{code}")

Hi,
Our team has moved away from providing geographic / projected CRS codes as
strings and prefer using integers where possible. However, in the C++ API, I
only see an integer based importFromEPSG function, which doesn’t appear to
accept ESRI codes (crs not found error message). We’re targeting an Albers
projection which is distinguished by an ESRI integer.
Curiously, the proj database doesn’t seem to make this distinction – the table
column is simply ‘code’ and I can find the projection row manually, alongside
EPSG projections.
Can such a function be provided by the API (if it doesn’t already exist – I
couldn’t find it – there are no integer overloads of importFromESRI)?
Please advise -- thanks,
Jesse
