The Bangalore Development Authority (BDA) recently published a list of private layouts that it deemed illegal and unauthorised. The main reason for the illegality of these layouts is the lack of DC conversion from agricultural land to residential use, and in some cases illegal encroachments.

The list published by BDA has survey numbers of the areas along with the Taluk and Village names. However, it suffers from some issues:

1. The document is available only in Kannada, and as such mapping the name correctly to the English version can be challenging. For eg: There is a K. Gollahalli under Bangalore South, which can be translated to Kengeri Gollahalli or Kumbalagodu Gollahalli – it is not clear which Gollahalli was intended.
2. Some of the villages are recorded in the wrong Taluk or Hobli, for e.g. Sulikunte is in Bangalore East but it is recorded under Anekal.
3. Many of the survey numbers have only parts, but the list mentions which parts in only some cases, not all.
4. The printing has left out the village numbers in a few rows.
5. Most of the maps published by the revenue department are in pdf format and not in tech-friendly kml format. Unfortunately, the maps of almost all of the villages where these illegal layouts are, are in hand-drawn pdf format, with numbering in Kannada.

Based on the survey numbers and the village numbers, we have made a map using the Cadastral map of Bengaluru which can be used to find out whether an area is in an unauthorised layout or no. However, a few caveats:

1. The cadastral map lists only survey numbers, not their parts. Where the BDA list mentions parts, we have mapped the full survey number. In case of queries with part numbers, please check the BDA list for details.
2. The cadastral maps mention a Village code, but the revenue department website has no mention of such a code. The website vlist.in provides the village code for village names based on which we mapped the BDA list with the Cadastral maps.
3. Where the villages could not be found, we have omitted them. For instance, the illegal layouts list mentions a village called Shivanahalli in Yelahanka, but the website vlist.in has no mention of such a village. Thankfully, the number of such villages is not significant.
4. For all these reasons, in case of discrepancies, the BDA list is the final authority, not the map provided below.

The layouts are spread around the North, North-East, East, South-East, South and South-West of the district.
