GeoAPI 1.7.5 is incompatible with latest ProjNet4GeoAPI

[kjeremy]

See NetTopologySuite/GeoAPI#50

[FObermaier]

Could you try this package:
https://www.myget.org/feed/nettopologysuite/package/nuget/ProjNET4GeoAPI

[HarelM]

I have tried the above package and it seems to solve the issue.
Can you please release/pre-release it to the regular NuGet repository?
This currently prevents me from bumping up the versions for the other NTS packages.

[HarelM]

@FObermaier any chance to publish your package to NuGet as a pre-release?

[HarelM]

@airbreather any chance you could help out here? I'm guessing this only needs to be published to NuGet...? This is currently a blocker in terms of upgrading to the officially released NTS version with all of the .net core updates...

[airbreather]

Should be done now, here was my test:

ConsoleApp0.csproj

<Project Sdk="Microsoft.NET.Sdk">

  <PropertyGroup>
    <OutputType>Exe</OutputType>
    <TargetFramework>netcoreapp2.1</TargetFramework>
  </PropertyGroup>

  <ItemGroup>
    <PackageReference Include="NetTopologySuite.Core" Version="1.15.0" />
    <PackageReference Include="ProjNet4GeoAPI" Version="1.4.0" />
  </ItemGroup>

        var wgs84 = worldMercator.GeographicCoordinateSystem;

        var transformFactory = new CoordinateTransformationFactory();
        var wgs84ToWorldMercator = transformFactory.CreateFromCoordinateSystems(sourceCS: wgs84, targetCS: worldMercator).MathTransform;

        var hollywoodSignWgs84 = new Coordinate(-118.3215, 34.1341);
        var hollywoodSignWorldMercator = GeometryFactory.Default.CreatePoint(wgs84ToWorldMercator.Transform(hollywoodSignWgs84));

        var laxWgs84 = new Coordinate(-118.4085, 33.9416);
        var laxWorldMercator = GeometryFactory.Default.CreatePoint(wgs84ToWorldMercator.Transform(laxWgs84));

        Console.WriteLine("Distance from LAX to the Hollywood sign: " + hollywoodSignWorldMercator.Distance(laxWorldMercator) + " meters");
    }
}

Output

hi!

i add to this - because i did not find an other way of help.

i even update to 1.7.5 in vb.net and my old code looks like

Dim csFact As CoordinateSystemFactory = New CoordinateSystemFactory()
Dim ctFact As CoordinateTransformationFactory = New CoordinateTransformationFactory()

    Dim gcs_WGS84 As ProjNet.CoordinateSystems.GeographicCoordinateSystem = ProjNet.CoordinateSystems.GeographicCoordinateSystem.WGS84

    Dim EPSG31468 As ICoordinateSystem = csFact.CreateFromWkt("PROJCS[""DHDN / 3-degree Gauss-Kruger zone 4 (E-N)"",GEOGCS[""DHDN"",DATUM[""Deutsches_Hauptdreiecksnetz"",SPHEROID[""Bessel 1841"",6377397.155,299.1528128,AUTHORITY[""EPSG"",""7004""]],TOWGS84[598.1,73.7,418.2,0.202,0.045,-2.455,6.7],AUTHORITY[""EPSG"",""6314""]],PRIMEM[""Greenwich"",0,AUTHORITY[""EPSG"",""8901""]],UNIT[""degree"",0.0174532925199433,AUTHORITY[""EPSG"",""9122""]],AUTHORITY[""EPSG"",""4314""]],PROJECTION[""Transverse_Mercator""],PARAMETER[""latitude_of_origin"",0],PARAMETER[""central_meridian"",12],PARAMETER[""scale_factor"",1],PARAMETER[""false_easting"",4500000],PARAMETER[""false_northing"",0],UNIT[""metre"",1,AUTHORITY[""EPSG"",""9001""]],AXIS[""Easting"",EAST],AXIS[""Northing"",NORTH],AUTHORITY[""EPSG"",""5678""]]")
    Dim utm32 As IProjectedCoordinateSystem = ProjectedCoordinateSystem.WGS84_UTM(32, True)
    Dim trans As ICoordinateTransformation = ctFact.CreateFromCoordinateSystems(EPSG31468, gcs_WGS84)

NewCoordinate = trans.MathTransform.Transform(OldCoordinate)

is there somebody who could help? the code example of airbreather i am not able to migrate to my project.

regards Jan

The information provided is incomplete.

• what kind of build failure message do you see?
• can you set up a sample that you can show?

[osmvermesser]

Hi!

i did not understand every think but here is the message of the vs

Hallo Felix,
vom Namen her vermute ich, dass Du aus dem deutschsprachigen Raum kommst. Leider verstehe ich Deine Rückfrage nicht so ganz.

Die Fehlermeldung aus VS habe ich oben einmal eingefügt.

Ein Beispiel? Die betreffenden Codezeilen habe ich ja auch schon vor Deiner Rückmeldung schon gepostet. Oder meinst Du etwas anderes?

Regards / Gruß Jan

[FObermaier]

@osmvermesser, while you are right about me living in germany, we don't want to exclude others.

Looking at the documentation for BC31091 reveals that there must be some mismatch. Can you post the packages that you reference in your project, or the content of the project file?

[osmvermesser]

@FObermaier , I don't want to exclude anyone and if I had understood what it was about I would have continued to write in English!

i attach my vb-file

niv2osmand.txt

the references:

I hope this are the required informations.?!??

Seems like your projNET4GeoAPI is not up to date...
Here's my proj file using 2.0:
https://github.com/IsraelHikingMap/Site/blob/6ba6a5e634154f560be00a96d0e69dbc5ecf3f81/IsraelHiking.API/IsraelHiking.API.csproj#L28
And here it was using 1.7.5:
https://github.com/IsraelHikingMap/Site/blob/3713aaee2ea54c391febdce66172a7e032db6684/IsraelHiking.API/IsraelHiking.API.csproj#L28
I hope this helps...

ProjNet v1.3.0.4 does not work with GeoAPI v1.7.5, you should use v1.7.3
ProjNet v1.4.1 works with GeoAPI v1.7.5
If you don't have any constraints that require GeoAPI I encourage you to use the ProjNet v2.0 package
