An FMB sketch contains several kinds of numbers: a survey reference in the header, measurements beside line segments, and labels around the parcel. The Chettipatti specimen below has an irregular outline, so reading it as a rectangular plot would give a misleading area. Start with the header and follow each segment before comparing the drawing with your own documents.
Confirm the place before reading the outline
FMB specimen for Chettipatti [53], Kulathur taluk, Pudukkottai. The central parcel is labelled 1A1. The red and blue numerals are already on the source drawing; the readings below point to their positions.
The header gives Survey No: 30/1A1, Area: Hect 01 Ares 82.00, and Scale: 1:1249. The footer identifies the Survey and Settlement Department and prints an issue date of 21 September 2026, separately from the approval date.
This is a different parcel from the 181/5A2 patta specimen. A similar-looking document is not evidence about your plot. Match district, taluk, village and the full survey reference before comparing area or neighbours.
Follow the lines, rather than choosing four sides
The north arrow is above the drawing on the right. The upper edge has several bends, with visible segment labels 37.2, 8.0, 67.4, 37.6 and 23.4. The label 24 is printed beyond the long upper segment. Along the lower part, visible segment labels include 50.8, 32.6 and 57.4, with 212 printed below.
The right edge is divided into shorter segments beside labels 1B1, 1C1, 1D, 1E, 1F, 1G and 1H. Measurements such as 13.6, 15.2, 16.2 and 18.4 sit along that segmented edge. They do not describe one single straight side. Point numerals and parcel labels also appear, so copying every number as a length would mix different information.
Use those positions as a reading aid, not a reconstruction of the survey. If a label is unclear on your copy, obtain a readable source copy or ask the survey office to interpret it. The diagram does not name every possible neighbour in a four-row north/east/south/west list.
Read the printed area separately from the scale
1 hectare and 82 ares equals 18,200 square metres. The header supplies that recorded area. The scale 1:1249 supplies a drawing ratio; it is not the area and does not mean the image will remain at that scale after a browser or printer resizes it.
This outline is not a rectangle. Multiplying two selected edge labels cannot check its area. A survey calculation would need the relevant geometry and measurement information, not just the longest horizontal and vertical lines visible in a screenshot. See hectares and ares to convert the units without changing the recorded value.
Whole survey and subdivision are different requests
In View Patta’s FMB lookup, a subdivision is optional. Leave it blank to request the whole survey; enter the subdivision to request that part. A blank is not an instruction to invent a subdivision of 0.
The source can have a subdivision drawing without a whole-survey drawing, or the reverse. A result saying that the whole-survey sketch is unavailable applies to that scope; it is not proof that all subdivisions are unavailable. Use the exact scope in your document. If the result names a missing subdivision sketch, selecting a different subdivision would describe different land, not repair the first request.
Compare documents and ground observations carefully
Put the sketch beside the property schedule in your sale deed, patta and A-Register. Write down disagreements in the identifiers, extent or adjoining references. A wall visible today and a line on a drawing are separate observations; a visual walk alone cannot establish that they occupy the same surveyed position.
The official e-Services help describes FMB as a diagram of land in rural areas. For a town-survey reference, use the TSLR sketch and its ward/block identifiers. For an unresolved physical boundary, ask the survey office what survey is needed. For disputed rights, take qualified legal advice before relying on the outline.
A sketch explains recorded geometry. It does not identify the owner or clear the transaction history; those questions require different documents, including the EC. View Patta offers checkout only after a complete record is prepared. A missing sketch produces no quote or charge.
