Unifly Elevation Library

Overview

The Unifly Elevation Library provides a converter to convert AltitudeInfo containing any height to an AltitudeInfo object that takes elevation into account by reading elevation model from a specific data source.

For now only TIFF files are supported as data source but other formats can be added in the future.

Dependency

In order to use this library, you need to add the following dependency in your service:

implementation project(":unifly-lib-elevation")
// or
implementation "aero.unifly:unifly-lib-elevation"

Geoid or Orthometric Height

Geoid or Orthometric Height

Setup Properties

You need to add the following properties to your application.yml file:

Property

Type

Description

elevation.models.tiff.classpath

Boolean

If true, the elevation model will be read from the classpath. If false, the elevation model will be read from the file system.

elevation.models.tiff.file

String

The path to the tiff file containing the elevation model

elevation.models.tiff.type

aero.unifly.elevation.api.ElevationModelType

Can be either ORTHOMETRIC or GEOID.

elevation.models.tiff.reference

String

The reference of the elevation model.
example
elevation.models:
  tiff:
    - file: mzytiff.tiff
      classpath: true
      type: ORTHOMETRIC
      reference: EPSG:4326
    - file: anotherone.tiff
      type: GEOID
      reference: CRS:1111
