The iodine value is the measure of the unsaturation of fats and oils. It is expressed as the number of grams of iodine absorbed by 100 g of the fat under the test conditions used.
Iodometry is a technique that is very important in volumetric analysis. It is for instance used to detect dissolved oxygen and chlorates in compounds.
example of idometry

salts of iodine is used to liberate iodine.i.e iodine is liberated indirectly
Iodometry & iodimetry Iodometry An application of iodine chemistry to oxidation-reduction titrations for the quantitative analysis in certain chemical compounds, in which iodine is used as a reductant and the iodine freed in the associated reaction is titrated
Iodometry, also known as iodometric titration, is a method of volumetric chemical analysis, a redox titration where the appearance or disappearance of elementary iodine indicates the end point.
For the best results reaction should take place in the slightly acidic solution (pH around 4-5), correct pH is obtained by addition of acetic acid.

When an analyte that is a reducing agent is titrated directly with a standard iodine solution, the method is called "iodimetry". When an analyte that is an oxidizing agent is added to excess iodide to produce iodine, and the iodine produced is determined by titration with sodium thiosulfate, the method is called "iodometry".

In iodometry sodium thiosulphate is used because it is standardized by potassium dichromate and it is the best and relaible way to standardized sodium thiosulphate using iodometric titration. Infact sodium thiosulphate is also standardized by iodimetry. The difference between both of them is only of iodine. In iodometry iodine gas is liberated that will further react with sodium thiosulphate but in iodimetry standard solution of iodine is used.

If you mean iodometry, it is the use of the chemical iodine in a process called titration. Titration is often used to determine the concentration of a chemical in a solution. A common use of iodometry was determination of salt concentration in salt water. It is not the most accurate or quickest way these days.

Starch undergoes­ decomposition in solutions with high I2 concentrations. (In this case I2 consumed in side-reaction) In titrations of excess I2 with Na2S203, addition of the indicator must be deferred until most of the I2 has been reduced. Skoog, West-- Chapter 20 page 564
