Pros of StreetComplete

• Focused on mobile use, making it easier for on-the-ground contributions
• Gamified approach with quests, encouraging more user engagement
• Simplified interface for non-technical users to contribute

Cons of StreetComplete

• Limited to Android platform, reducing accessibility for iOS users
• More constrained editing capabilities compared to iD's full-featured editor
• Primarily designed for adding specific types of data, less flexible for general editing

Code Comparison

StreetComplete (Kotlin):

class QuestAnswerComponent(
    private val osmEditController: OsmEditController,
    private val questController: QuestController,
    private val soundFx: SoundFx
) {
    // Implementation details
}

iD (JavaScript):

export function osmEntity(attrs) {
    var entity = {};
    entity.tags = {};
    entity.id = attrs.id;
    // More entity properties and methods
    return entity;
}

StreetComplete uses Kotlin and focuses on mobile-specific components, while iD uses JavaScript and provides a more general-purpose entity structure for OpenStreetMap data manipulation.

Pros of OMIM

• Offers offline mapping capabilities, allowing users to access maps without an internet connection
• Provides a more comprehensive mapping solution, including navigation and search features
• Supports multiple platforms, including iOS, Android, and desktop

Cons of OMIM

• Larger codebase and more complex architecture, potentially making it harder to contribute or maintain
• Less focused on editing OpenStreetMap data compared to iD
• May have a steeper learning curve for new developers due to its broader scope

Code Comparison

iD (JavaScript):

context.enter = function(mode) {
    if (mode.id === context.mode().id) return;
    context.history().perform(function() {
        context.mode().exit();
        context.mode(mode);
    });
};

OMIM (C++):

void Framework::ShowPlacePage(place_page::Info const & info, place_page::SponsoredType sponsoredType)
{
  m_work.GetGuard();
  auto const & mwmInfo = info.GetID().m_mwmId.GetInfo();
  if (!mwmInfo)
    return;
  m_currentPlacePageInfo = info;
}
