After the Haiti earthquake the Haitian government with the support of Miyamoto engineering, built a windows mobile application to manage ATC-20 building evaluations of the tens of thousands of collapsed structures. This took almost 2 months. With windows mobile holding a diminished market share it is time to write an updated application for iphone and android that a government can deploy quickly with volunteer and official survey teams. The Sahana Eden platform was used for this task in New Zealand and there has been a start made at an ATC-20 application for Sahana but there is still a bit to go in having a mobile app specifically around ATC-20 on a Sahana backend.
Should there be a major earthquake a government could deploy a server that can recieve data from the ATC-20 app. Teams getting on the ground within the first week after a quake could easily download the app and upload the data to the government server when an internet connection was available.
The app itself should have the ability to take GPS readings and photos.
This is similar to the post disaster evaluation tool project except specifically focussed on ATC-20 evaluation of buildings after earthquakes. I can provide teams with a copy of the ATC-20 checklists and framework in PDF.
