USGS Website

Almost there… I have my AFS account, can view files, but just need write privileges.

Had a discussion about hosting some project work/documentation/products on non-USGS or .gov domains and the conclusion was it does not matter.

New JavaScript Framework

Switching to Angularjs, an Open Source JavaScript Framework

Easier to Extend and Modify Maintains Separation of Data Model, Web View,

and App Controller Allows Greater Ability for Testing

SVG Charting Library

Building a Custom Scalable Vector Graphic Charting Library with Angularjs The currently available options have

limitations for this particular application. Bar charts and line charts Primary reason is to reduce memory usage

and latency when dealing with a significant amount of data.

Web App Changes

Improved Zoom Controls with Zoom to World Opacity Controls for Layers Improved Loading and Working Interface for User Ability to Select Rectangular Area of Map

Select Markers and Get Histogram of Classes Query Google Earth Engine for Area per Class in Our Data

Products (Still Writing EE Scripts) Working out the best interface for users to provide information

by year.

And more features in the works: photos, comments, etc.
