Batlimous, a Greek geographer, topographer, mathematician and writer (2nd century AD), in his book named 'the World Maps' which includes 27 maps of the different parts of the world, has named the Persian Gulf as Persicous Sinous which means the Persian Sea.

The ancient city has 'known several civilisations, from the Mauritanian era to the Romans through the Islamic period', according to Mohamed Alilou, topographer and assistant conservator of the site.

Topography was done in each patient using placid disc-based Atlas Model 9000 Corneal Topographer. Four keratographic images ensuring proper fixation were taken.

Determination of corneal power with a keratometer (or only the data from the anterior surface of the cornea obtained with a corneal topographer or tomographer) uses the keratometric index, which allows obtaining that approximate value without measuring the curvature of the posterior surface of the cornea, which constitutes an approach with results quite close to reality in virgin corneas.

After centration of macular topographer on fovea, macular scans were taken to get retinal thickness map.

The quality of images is automatically determined by the corneal topographer. In our study, two images with high quality were included in order to avoid the risk of operator bias.

Measurements of noninvasive breakup time (NIKBUT) obtained with the advanced corneal topographer provide a simple, noninvasive screening test for dry eyes with acceptable sensitivity, specificity, and repeatability [9].

Under orders from General Charles Gratiot--namesake of the Michigan county, fort, and avenue--Lieutenant Lee was to serve as a topographer. The expedition was commanded by Lee's old friend Captain Andrew Talcott.

Identikit developed into Photofit which was developed over the following decade due to a system invented by Jacques Penry, a facial topographer who had been researching the subject since 1938.

Finally, in "Two Pioneers of Central Asian Exploration: Sir Aurel Stein and Sven Hedin" Bosworth compares the travels and work of two well-known explorers, Stein as linguist and archeologist and Hedin as geographer and topographer. In the service of British India, Stein made four expeditions to Chinese Turkistan between 1900 and 1931, discovering, above all, enormous caches of documents in many ancient languages.
