Hi.. Few similar attempts have been made by organizations such as Lake Development Authority <http://www.karunadu.gov.in/lda/>, and ATREE<http://www.atree.org> . You can collect basic data from them. Also you can get information about the methodology they adopted.
You can definitely use remotely sensed data for your study to 1. Create shapefiles, using satellite images as base. 2. using DEM to delineate catchment area You can use recent satellite images (either from NRSC or Landsat) which are available at a price. or, you can use freely available old images. -Prabhanjan On Sunday, June 16, 2013 12:01:22 AM UTC+5:30, Kavita Arora wrote: > > Hi All, > > I am part of one focus group of the larger "Save Bangalore Lakes" > community initiative that aims to provide an open forum to discuss the > degrading (or improving) condition of Bangalore's Lakes. > > As part of our ongoing research to obtain as much information about the > lakes and other water bodies -- we are piloting a new data science exercise > where we plan to attempt collecting as much raw data (from scratch) about > the lakes - including catchment areas, lake peripheries and other measures. > > Although some of this work has been done before, in order to be completely > objective and not introduce too much bias into our project -- we are trying > to figure out how to capture and analyze raw data collected from scratch - > such that we can come up with insights we may have overlooked before. > > Was hoping to get some ideas from some of you in this group as to how to > go about the following: > - How to go about capturing remotely sensed data > - How to convert raw data captured via Remote Sensing into shape files > - Understanding the process of building a basemap from scratch > - Annotating, tagging and modeling the adapted data > > I know I am basically asking for "all the answers" but we have a team of > volunteers in place and need someone/some people to give us a few pointers > in the right direction so we don't run around in circles too much. > > Anyone have any advice? > > thanks! > > kavita arora > > > > > > -- For more details about this list http://datameet.org/discussions/ --- You received this message because you are subscribed to the Google Groups "datameet" group.
