Develop location data IOS app

An IOS app to collect, view and rank heritage trees in KSA. The application aims to increase the awareness about natural assets and permit the user to access a dataset of outstanding trees. The georeferenced data is shown on a map and list and detail view. Images and tree properties are a detail view editable in the detail view. The UI is available in English and Arabic.
Attached a scope description and sample data. Let me know if there are any questions.
We previously purchased an IOS template for geolocation app development (http://myapptemplates.com/product/whats-here-android-app-templates/).
