Adopt-a-Plot for iOS

The Adopt-a-Plot app is a geolocation-based app that displays the user's real-time position in relation to pre-loaded, or user-defined, map-based polygons, and it contains several user-friendly features. The app was originally designed to help forest maintenance citizen volunteers (of the Bay Ridge Civic Association, in Maryland), and for that purpose, it contains 105 pre-loaded geofenced plots. However, any user, worldwide, can easily enter a self-defined polygon and use the app for similar real-time relative geoposition visualization purpose.

The Adopt-a-Plot app uses the phones GPS to continually triangulate and display the users position. At the same time, the boundaries of the selected polygon are accurately displayed as a map overlay. The accuracy of the users location, in relation to plot boundaries, is limited only to the inherent accuracy of the phones GPS (typically about 15-30 feet). If needed, accuracy can be improved by pairing with an external GPS.

Users can simply scroll through a list of pre-loaded plots or create their own plot by inputting exact latitude and longitude coordinates. The app draws a red box around the desired area and displays the location of the user as a pulsing blue dot.

Included Features:

Real-time positioning

Drop down menu of currently programmed plots

A coordinate input function

Icons to zoom in and out of the map

Accurate red border around the desired plot as map overlay

Icons to switch the view between the user and the selected plot, and

An instructions menu, specific to Bay Ridge, Maryland, that describes how to cut the invasive species in forests along with safety precautions of going into the forest.

This app can drain phone batteries, so it is suggested to bring a portable charger or turn off the phone when not in use.

This app was developed in 2019, as a Community Challenge Project for the benefit of the Bay Ridge Civic Association, by a group of South River High School junior year STEM students: Ari Wasch, Samara Hatley, and Nick Merton. In particular, Ari wrote the code using Xcode for the Apple app and Android Studio for the Android app.
