Nevada Fish Passage Assessment Database
The U.S. Fish and Wildlife service in Nevada monitors and manages passages throughout the state. The
data collected has been stored in a database with limited options for continued analysis. In collaboration
with MDEP over 6,000 points of data have been processed into GIS data layers for greater utility along with
other supporting data. This project continues to develop with the near future launch of a mobile data
collection system, improved open source map portal and additional data resources increasing the utility of this
decision support tool.

NTSB Aviation Crash Heatmap
The Aviation Crash Heatmap is a dynamic webmap using the Leaflet java script library and various plug-ins. This map uses data from the National Transportation Safety Board (NTSB) Aviation Accident Database and Synopes. The map displays this data in three ways: point data, showing nearly 24,000 points all over the world where the NTSB has investigated aviation incidents. The second way the data is displayed is a heatmap, showing hot spots where crashes have occured most frequently over the entire NTSB record (that contained coordinates). The third way the data is displayed is as an animated heatmap with a time slider; through this layer the data shows hot spots month by month from December 1999 to December 2015, by looking at certain months a user can see where crashes occur most frequently and a user can analyse what season, or any particular month that has historically had more plane crashes according to NTSB data.

Crash App v2 (Recovery of Crash Site)
Developed in partnership with Shilpi Jain, Masters Student at the University of Redlands, this project is a redesign of the original Windows Phone Application in HTML 5 so that it is no longer platform specific.
The Recovery of Crash Site Application (RoCS) was rebuilt using
Recovery of Crash Site is a web application developed to help first responders, investigators and clean-up crews estimate the probable debris area
of an airplane crash. User provides some basic crash and aircraft specific parameters which are used for the estimation, the results of which
can be saved or emailed.
The results map can be overlaid onto several base maps and the user can toggle the visibility of the
National Geospatial-Intelligence Agency (NGA) US National Grid layer over it to aid in coordination efforts. In addition, the user can add to the
database of aircraft and relevant data and the entire database can be downloaded as an Excel file.
The application can be accessed from a device which has an internet connection, a GPS and a compatible browser.
Mozilla Firefox or Google Chrome are reccomended.
Crash App v1
The Crash Site Debris Recovery Mobile Application (CSDRMA), or Crash App, is a prototype Windows Phone Application designed to assist crash investigators, first responders, and clean-up crews to locate aircraft crash debris in ground impact crash situations. The application specifically projects an estimated area of high debris concentration by utilizing a debris trajectory formula, the GPS location of the mobile device, Geographic Information System (GIS) functionality, an internal library of aircraft attributes, and user-defined variables of the affected aircraft and its crash characteristics. In testing, the application has shown to be promising in furthering the development of mobile applications for use in airplane crash events.
