Lat/Long how to display correctly

You can use a StringSearcher and look for the regex

(\d+)

Remember to specify the "Subexpression matches list name", e.g. as "_values". You'll then get the individul values in the list attribute _values{}.part, which you can pass on to the DecimalDegreesCalculator:

You can then pass _decimal_degrees to the VertexCreator. Remember to do this for both latitude and longitude.

Thanks for your quick response

I can extract the Degrees information using the (\\d+) into _degrees, but am struggling to work out how to extract the Minutes information using the same expression

Regular Expressions, like quite a few things in FME, are still a struggle for me to understand

You probably need two StringSearchers and two DecimalDegreesCalculators, one pair for jpeg_exif_gpslatitude and one pair for jpeg_exif_gpslongitude. You can simply chain them together. Just make sure that you use different result names for the lat and long parts.

For example:

Thanks for your response

I have my StringSearcher set up the same as you have displayed, but the (\\d+) Regular Expression only gives an output of 52, from the initial value of (52) in the exif information.

I'm struggling with the syntax to output the (\\d+) to display the minutes, in this case 15 (where the exif information displays the field as (52) (15) (7)

Hi there

I've attached the output in the Inspector, as well as a screenshot of the workspacetransformer.png

Just a quick thank-you to those that provided advice on how to do this.

It has worked up to a point, but when I run the Vertex Creator transformer, in spite of setting the output as shape point, the result is four points on a map.

Also the data is required in British National Grid format, so I am using the CsmapAttributeReprojector transformer, but the resulting output ends up somewhere in Scotland, when it should be Northamptonshire

I do have another workspace which uses the PhotoCoordinateExtractor transformer and that appears to have worked, with the point in the correct location when viewed in QGIS, so i'm going to go with that for the time being.

Once again, thanks for the advice

I'm trying to do this same thing however I can't get the vertex creator to work. It keeps failing at the vertex creator and is rejected. Is that what the red circle beside your creator? Was it also rejected?

If everything is failing in the VertexCreator then it's likely that the attributes you are attempting to use here are either not populated, or contain non numerical values. Have you inspected the data to check that you are generating the x and y values correctly?
