Analyzing the BDA RMP2031 Masterplan https://textb.org/t/rmp2031/>

• Analyze the masterplan for your area using https://answerquest.github.io/overlap-custom-side.html
  • By default the map compares the existing and proposed landuse on the city level over the satellite image of Bengaluru
  • It is possible to compare with any other map, but only if it has been georeferenced and uploaded to mapwarper SEE: http://opencity.in/explainer/georeferencing-image-maps-on-to-a-gis-map>

  • ELU http://www.bdabangalore.org/TPM_ELUMaps.html>
  • PLU http://www.bdabangalore.org/PLUMaps2031.html>

• Each planning district PDF map is divided into multiple pages, usually 4 quadrants

  • You need to convert each page separately, so first split the pdf in individual pages (suggested software: pdfsam)

• Export each map as a high resolution PNG or TIFF (DO NOT USE JPEG)

  • OSX: Open the pdf in Preview and export to image with 150ppi resolution
  • Others: Use a PDF-> PNG converter (website: http://pdf2png.com/)>
