    Challenge Overview

    Summary

    The Environmental Protection Agency (EPA) has asked TopCoder to build an Android app that will inform local and federal policy makers about the proliferation of a type of water pollution called cyanobacteria. The app will display past and current data about cyanobacterial concentrations and show predictions based on an algorithmic model that is being developed separately by TopCoder.

     

    Project Background

    The EPA is a U.S. federal government agency devoted to safeguarding the environment. One of the EPA's great concerns is the profileration of cyanobacterial harmful blooms (cyanoHABs) in the nation's lakes. The following resources provide information on what cyanoHABs are and how they threaten the environment.

    The TopCoder project on cyanoHABs aims to develop an Android app with mapping and data visualization capabilities that will incorporate an algorithmic prediction model. The app will inform local and federal policy makers about locations where bloom events are likely to occur, allowing them to concentrate their efforts in those areas. The algorithmic model does not exist yet. It will be developed in a separate track that culminates in a Marathon Match, which is not in scope here. In this contest, we are only conceptualizing the Android app and the associated server software.

     

    User Flow

    The EPA's expectations for the app are described in the attached questionnaire. Note especially the antepenultimate section, "Wish list", containing a list of required features.

    To help the conceptualization process, we ran a Studio contest to develop visual concepts for the user flow. The results are attached. These visual concepts are not precise definitions of the user interface. They are intended to guide you in documenting the business requirements for the app. The winning conceptualization will serve as the basis for wireframing the complete app, and the production storyboards will be developed after that.

    We would like to combine the best ideas from each concept. Note the following features of concept A:

    • the main UI layout with the idea of marking locations on a map for later review
    • allowing the user to select satellite images which are placed side by side for comparison
    • displaying a line chart of cyanobacterial concentration over time at a given location
    • superimposing line charts from different locations for comparison

    We are interested in the following idea from concept B:

    • varying the size of location markers to reflect cyano levels (screen 01)
    • showing a thumbnail of an alternate image prior to download (screen 05)

    The following idea is interesting in concept C:

    • a live feed of new events (screens 02, 03, 04)

    You may propose additional ideas of your own.

    Admin Website:

    We also want to develop an admin website in parallel to the app and need to include the flow for that in the conceptualization. The admin website is not described in the questionnaire.

    The main requirements for this website will be:

    1.) It will be a single page simple admin module

    2.) It will be mainly used to upload the data that will be used for prediction

    3.) It can also be used to edit/remove any uploaded data or the data pushed by the app users.

    4.) The module will interact with the same data source as used by the mobile app.

    We envision this module as a separate web page instead of part of mobile app backend as the data uploading could be large and time consuming. Btu if there are ideas which could make this module a part of mobile backend and be efficient to operate, you are free to present them.

    Technical Requirements

    The mobile app will support Android versions 2.3 and up. We are targeting mid-sized, mid-level mobile phones like the Nexus 4, which has the following screen specifications.

    • 4.7 inches (12 cm) diagonally
    • 1280 x 768 pixels

    These are the minimum screen dimensions we want to support. The interface will be designed accordingly.

    The specifications for the data server are currently unknown. We expect that any software libraries used in developing the server software will be available at no cost under a liberal license that allows unrestricted commercial use.

    enlightened Tip for Success: Start early and ask in forums promptly when in doubt. Keep an eye on discussions in forums.

    Final Submission Guidelines

    What to submit

    Fill out a standard Conceptualization document, making sure to delete the instructions and other boilerplate. Please submit original content only. You may link to external resources, but do not copy text, tables, or images into your document. You may quote brief portions of text from external documents with proper attribution.

    Reliability Rating and Bonus

    For challenges that have a reliability bonus, the bonus depends on the reliability rating at the moment of registration for that project. A participant with no previous projects is considered to have no reliability rating, and therefore gets no bonus. Reliability bonus does not apply to Digital Run winnings. Since reliability rating is based on the past 15 projects, it can only have 15 discrete values.
