Resumen
The knowledge and skill sets required for the next generation of astrometrists have increased dramatically from that needed in the past primarily due to the rapid increases in measurement precision and accuracy enabled by technological advances. The era of micro-arcsecond accuracy was launched by radio interferometry and ESA's Gaia satellite will soon provide that level of accuracy in the optical part of the spectrum. Some of the skills required have been a part of the education system in the radio-astronomical area but due to the lagging of technology in the optical part of the spectrum they have not been included in most optical astrometry courses. To rectify this deficiency I organized a group of specialists in the required areas and together we wrote a new introductory textbook on astrometry whose goal is to educate students and researchers in the methods required to deal with collection, reduction and analysis of micro-arcsecond positions, parallaxes and proper motions.
