[Geoserver-users] Alignment problems with ESRI software

Hello,

There is the international inch (25.4 mm) and the US Survey Inch (25.4000508
mm), which one is Geoserver actually internally considering an inch?

Our current scales that work correctly with the ESRI JavaScript API are
based on the US survey inch, whereas the scales that work correctly with
ArcMap are based on the international inch.

Puzzled.

Christian

You could check the JSR javadocs to see which one is in use, or the source code.

Let me check: http://jscience.org/jsr-275/api/javax/measure/unit/NonSI.html#INCH

public static final [Unit](http://jscience.org/jsr-275/api/javax/measure/unit/Unit.html)<[Length](http://jscience.org/jsr-275/api/javax/measure/quantity/Length.html)> **INCH**
A unit of length equal to `0.0254 m` (standard name `in`).

Still if you need to define more units you can, does the WKT or EPSG provide an EPSG code for the different units so we can tell them apart?

Thanks Jody,

but it still could be either, because this class has both units:

static Unit<Length> FOOT_SURVEY_US A unit of length equal to
1200/3937 m (standard name foot_survey_us).

and

static Unit<Length> INCH A unit of length equal to 0.0254 m
(standard name in).

O.k. that means trawling through the sources. At least I know now, what to
look for.

Cheers

Christian
