Dear all, just a follow-up to this oldish thread: I recently switched to the newest version of TesserAct OCR to transform buggy PDF rolls to text - and it works surprisingly well. Small typos here and there, but that can be rectified. In case anyone else looks for a solution to this... Best,

Hi Siddhart, for my UP dataset, I used spatial matching of polling booth locations against the MODIS urban extent satellite layer of 2002 - tends to be larger urban centres, though. Another option is to look at how many polling stations have multiple booths [polling stations being defined as

Hi Avinash and all, I realized that each constituency falls within only one district in your file, but there are constituencies that span several districts and vice versa (rare, but it happens). I attached a list of those, extracted from polling-station data on eci-polldaymonitoring.nic.in. These

thanks. the rule, as far as i remember, is that ACs are entirely contained within a district boundary. PCs, on the other hand, can span across district boundaries. A On Sat, Mar 15, 2014 at 1:19 PM, Raphael Susewind li...@raphael-susewind.de wrote: Hi Avinash and all, I realized that each

Hey Avinash et al, using population figures for matching is a neat idea, great! Meanwhile, I made both legal (licensing issues) and mathematical progress on matching 2001 Census villages to 2014 polling booths. I have a large conference next week which might delay things, but I expect to bring

Interjecting in a fantastic conversation... (Kudos to Avinash Raphael and others for the efforts to mix/match AC-PC and administrative jurisdictions).. There is no direct containment of ACs within a district. Case in point is Delhi, where ACs dont' fit single districts at all. Avinash, Trouble

Hi Avinash, Thanks a ton for pointing out the excel files with delimitation. I read what you wrote. Will take a look at the zip fie and cross-check. I too had hoped the district mapping was contiguous with some political boundaries, but they aren't. Bangalore, funnily has a ward (44 I think)

Hey Avinash, yep - thats what I figured, too. Not only misplaced matras (those could be rearranged), but a real garbling, which cannot be resolved as far as I see. Worse, there isnt even a clear pattern - for a few constituencies, I fed the Voter ID (which is in latin script) to the search roll

Hi Anand, Thanks, but the csv link me only has the PC to AC mapping (still awesomely useful!). Also hoping for ward level details. My intent isn't necessarily focused on Voter Rolls. It's on the larger census data itself. What % of the population is enrolled at the PC (or AC or Ward) level?
