</div><div><br></div><div>the only issue is that the district data is outdated (2001) and many new districts have been carved out and merged. two things can be done:</div><div>1) wait for another free updated gis dataset from the govt (most probably only 2011)</div>
<div>2) put in the existing data as a starting point, which is in any case quite useful and good for most parts.</div> </div><div class="im"><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">
<div><ul><li>Are there any district boundaries that are already well mapped and need to be excluded?</li></ul></div></blockquote></div><div>only the chennai city boundary which should be a lot more detailed than the census one. all other existing boundaries were from the 2001 census data </div>
<blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div><ul>
<li>Any other thoughts?</li></ul></div></blockquote><div>do preserve all metadata for the shapes, like district code or number. one more thing that needs to be done is the merging of districts to create the state boundaries. <a href="http://bitterscotch.files.wordpress.com/2008/06/india_map_outline.png" target="_blank">This map</a> should be a good reference for doing that . Another issue is for Kashmir districts, i believe the whole PoK part is one district, this might need some different tag maybe boundary=disputed</div>

<div><br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div><br></div><div>If no problems, I can bulk upload the data. My process will be:</div><div><ol><li>
upload a single district boundary</li>
<li>Check if it was uploaded and rendered correctly</li>
<li>Upload the remaining district boundaries</li></ol></div></blockquote></div>i feel its about time this was done, as boundaries are something that we cant map with a gps, we are limited to official datasets, and this counts as the latest official release from the government<br clear="all">
