I volunteered as presenter at Drupal Camp 2012, with two topics.
2. Drupal for Government Transparency and Good Governance with Co-presenter Charie Villa of ABS-CBN
We highlighted taopo.org as tool for government transparency and good governance. It uses major modules, like panels, views, display suite, web services(restful json for Android Phone integration and IOS).
2. Intelligent Mapping using Openlayers
Automate generation of latitude and longitude using wkt, just adding address and you will be free from hazzle of manually inputting locations(lat and long).
Build an intelligent search engine using map, add proximity filter using distance.
