NetTopologySuite.IO.GPX 0.5.0

NetTopologySuite.IO.GPX

See GitHub Pages for the latest and greatest docs.

Adds reading and writing capabilities to convert between GPX (*.gpx) files and NetTopologySuite features.

Or, if you'd like, you could use this to simply read / write the data exactly as stored in the GPX files using a rich, strongly-typed, unambiguous data model.

Targets .NET Standard 2.0.

Release Notes

0.5.0

• GpxWriterSettings.TimeZoneInfo is no longer completely ignored (#30).
• Fix an issue where written timestamps were being rounded to the nearest second instead of preserving as many significant digits as DateTime allows (#31).
• Tweak the settings used for GpxFile.BuildString to avoid repeating the xmlns declaration for extensions that are declared in the standard GPX namespace (#33).

0.4.0

• GpxReaderSettings now has an IgnoreBadDateTime property to use for ignoring a timestamp value that we cannot parse as an instance of the DateTime struct, to work around a 0000-00-00T00:00:00Z coming from CompeGPS (#29).
• Update referenced packages to latest revisions.

0.3.2

• The opt-in GpxReaderSettings.AllowMissingVersionAttribute property added in 0.3.1 has been replaced by IgnoreVersionAttribute, which enables the same situations as AllowMissingVersionAttribute did, plus situations where version was specified as something other than version='1.1' (#28).

0.3.1

• GpxReaderSettings now has an opt-in AllowMissingVersionAttribute property, to allow reading files without a version attribute (#27).

0.3.0

• GpxReaderSettings now has a DefaultCreatorIfMissing property to use for filling in a missing GpxMetadata.Creator value, to help read values saved from legacy versions of IHM (#23).
• Custom GpxExtensionReader and GpxExtensionWriter subclasses can now override just one method if there's a common way to handle extensions regardless of where they show up (#26).
• All immutable data model types now override Equals(object) and GetHashCode() to have "value" semantics (#9).
  • Mutable types, such as GpxFile, do not do this, for your own safety.
  • In all lists, including lists of web links, ordering matters. [A, B] is not considered equal to [B, A].
  • Extensions values are considered for equality.
    • If you do not use a custom GpxExtensionReader for extensions, or if yours always returns ImmutableXElementContainer, then this should work like you would expect it to work.
    • Otherwise, whenever you return non-null, it is your responsibility to make sure that the result's Equals(object) and GetHashCode() semantics match what you want the container's semantics to be.
• GpxWebLink now has a constructor that accepts just the value for Href, since that's the only required value.
• GpxLongitude no longer permits +180 as a legal value, in keeping with the GPX 1.1 schema. (#25).
  • Converting from NTS features will automatically replace +180 with the equivalent -180.
• GpxLongitude, GpxLatitude, GpxDegrees, and GpxDgpsStationId now all have static MinValue and MaxValue fields to get the smallest and largest legal values.
• GpxBounds now has a shortcut for getting the a value that covers the entire WGS-84 ellipsoid.
• GpxWaypoint now has a constructor that accepts a GeoAPI.Geometries.Coordinate instance, for convenience (#20).
• GpxWaypoint constructors and helper method now both reject infinite values of elevationInMeters (#24).
• GpxWaypoint constructors and helper methods now throw ArgumentOutOfRangeException instead of ArgumentException in situations where the former is more appropriate.
• Trying to set GpxFile.Metadata to null now throws ArgumentNullException right away (#21).
• Add methods on GpxFile to allow converting to / from string, for convenience (#19).
