U.S. Department of the Interior U.S. Geological Survey Data Collection, Product Dissemination and Process Automation GFSAD30 January 2016 Workshop Justin Poehnelt, Student Developer

Overview of Work and Resources  Web Application  Mobile Application  Primary Server  Python Flask REST API  Secondary Server  OGC/Geoserver  Python Celery Async Worker  Postgresql Database

2015 Achievements  Mobile Application Implementation  Reference Data Ingestion Flow  Automated Reference Data Export  OGC Server  Website Updates with New Products

Mobile Application Cordova hybrid mobile application using Ionic framework with Angularjs  Android: Current  iOS: Several versions behind croplands.org/mobile

Mobile Application Unit Testing  Continuous testing with Travis, Karma and SauceLabs  Challenges still remain for testing on actual devices.  Manual error reporting within application needs to be automated.

Mobile Application Offset  Allows users to collect data from edge of field or area of interest.  Prevent data collection errors.

Mobile Application Offset Distance

Mobile Application Accuracy

Mobile Application Accuracy: Mali

Reference Data Ingestion  Automate split of training and validation sample units.  Prevent overlapping training and validation sample units. (1000 m threshold)  Can be expanded for quality control with other factors such as distance to road, water or NDVI mean.

Reference Data Export  Currently exporting data to two Google Fusion tables  Validation: 12WLGpk7o1ic_j88NQfmrUEILVWDlrJaqZCAqEDeo  Validation Link:  Training: 1C_gFvQmd3AGtB0Q0XgnKk5ESUARSH79FB9Un8sF2  Training Table Link:  Can be shared through other file types and with additional columns from database.

OGC Server  Transitioned from Google MapEngine to Geoserver Instance.  Geoserver added to instance already running asynchronous tasks  WMS Link 0&request=GetCapabilities

Products on Croplands.org  Easy to incorporate WMS layers into web application.  Switching WMS styles to show different products such as crop extent or crop dominance.  Switching WMS layers to change between years.  Still fine-tuning server settings so please don’t crash it!

Products on Croplands.org

Upcoming Work  Transition to USGS Cloud Hosting  Automating SSL/TLS with LetsEncrypt Service  Updates to iOS Mobile Application  Automating Error Reporting in Mobile Application  Push Notifications for Feedback to Mobile Application Users  Refactor Web Application  Transfer to NASA URS for Authentication
