A comparison dialog for OSM elements

ElementHistoryDialog

Compare changes between 2 different versions(in history) for any node, way, relation in OpenStreetMap

Highlights:

• Different version based on user edits
• Changes in Description, Imagery Used, Source for the data (Changeset)
• Changes in the tags between 2 versions
• Changes in node coordinates between 2 versions
• Changes in way nodes between 2 elements
• Changes in relation members between 2 elements

Usage:

The library takes 2 parameters

• The id of the element

  • This is a Long representing the OSM id of the current selection

• The type of the element

  • node
  • way
  • relation

Example Usage -

• Add the project using jitpack

 allprojects {
  repositories {
    jcenter()
    maven { url "https://jitpack.io" }
  }
 }
 

• Add the dependency

dependencies {
          implementation 'com.github.zedlabs:ElementHistoryDialog:1.0.1'
  }

• The dialog extends the android DialogFragment, so it can be instantiated similar to any other DialogFragment

 // from an activity
 // with element id = 1 and element type = "node"
 
 ElementHistoryDialog ehd = ElementHistoryDialog.create(1, "node");
 ehd.show(getSupportFragmentManager(), "sample");
