Department of Geology to launch a new community driven project titled "Geology of Goa"
Geology of Goa has been a subject of intense study during the past, several noted geologist have worked and mapped the geological resources of Goa. There is a vast literature already published on the subject with beautiful description and a few photographs of the outcrops. It is noted that most of the work was done several decades earlier when the use of technology such as GIS was not very widespread as it is today. Any newcomer who wishes to study these outcrops almost certainly has to painstakingly scan the terrain using only the descriptions and guidance of fellow colleagues to find the locations of outcrops given in the literature.
This process is tedious and unnecessary if the location of these stratotypes are geotagged and stored in a database. This will allow the future geologists to save a lot of their precious time to focus on the analysis of their study rather than data gathering. Therefore there is a need to revisit these outcrops from which the Geology of Goa has been deduced and geotag their exact locations along with the photographs, samples collection and field descriptions.
With the advent of mobile phone technology incorporating inbuilt GPS systems and the widespread access to free open source GIS tools it has become possible to carry out this task of geotagging outcrops in a systematic and efficient manner. The Department of Geology, Parvatibai Chowgule College of Arts and Science Autonomous, Margao, Goa has thus proposed a geology community driven project to map all the rock exposures in the state of Goa by use of field data collection app on mobile phones. The project titled as "Geology of Goa" has been configured in Epicollect5 which is a mobile and web application for free and easy data collection. Once a user is added to the project, he/she can start collecting field data by first downloading the app and loading the project to which he/she has been added. Data collection is done by filling in a template which has been created specifically for this project, the template is made simple for ease of use with basic inputs. locations and photographs can be directly added from the device. The beauty of this system is that sevreal users can be working in diffferent areas and simultaneously contribute data to a common database. Thus wider coverage can be achieved in a shorter time. Contrary to the common belief this system can effectively function in the field even in the absence of a telephone neetwork as the data is stored on the local storage of the device and can be uploaded onto the server later when access to the neetwork is available (Note: The inbuilt GPS system does not require a telephone neetwork to function). Once the user uploads the data it will be validated by a team of experts and further study may be planned. Once an exposure has been determined to be of significance it will be added to a seperate database containing only the validated outcrops. All the data locations and thier attributes (information) can be then visualized in a Web Map.
We welcome all the stakeholder including Researchers, Geologists, Students to contribute to this project and to our understanding of the Geology of Goa. Any person who wish to be added to the project can fill in the joining form on this link
Thank you.
