Fmb Sketch Online
The Field Measurement Book (FMB) sketch is a detailed map compilation stored in volumes at the respective Tahsildar office. These sketches, maintained at a 1:1000 or 1:2000 scale, detail individual survey numbers and their sub-divisions, illustrating precise land dimensions. Fmb Sketches play a crucial role in property transactions by verifying land measurements and boundaries.
Obtaining Fmb Sketch
To obtain an FMB sketch, a written request must be submitted to the Tahsildar office. The office holds these sketches and can also conduct property surveys upon request. Here’s a sample Fmb Sketch for reference:

Components of FMB
The FMB includes several components crucial to understanding the layout of a property:
- G-line
- F-line
- Subdivision lines
- Ladder
- Extension lines
- Neighboring field survey numbers
Here's a detailed look at these components:
G-line
The G-line shapes the sketch by dividing it into various triangles to define boundary lines and points. Errors in the G-line can impact all calculations.
F-line
The F-line establishes the field boundaries in the sketch. It is demarcated by measuring its offset from the G-line.
Subdivision Lines
These lines outline small land portions within a survey number. They are essential for determining each sub-division's extent.
Ladder
Defined through an offset from the G-line, ladder measurements can be converted into data to outline the Fmb Sketch accurately.
Extension Lines
These lines connect the survey field to neighboring fields, outlining their direction and relation in the sketch.
Neighboring Field Survey Numbers
Marked around each FMB, these numbers help convert Fmb Sketches into D-sketches, correlating the fields in a mapped layout.
