OverJohann Jacob Vorlaender (Source: wikipedia):

Johann Jacob Vorlaender (also: Vorländer) (* 3. October 1799 in Allenbach; † 10. March 1886 in Minden) was a Prussian geodesist.

Life and work: Johann Jacob Vorlaender was born on January 3rd. October 1799 in Allenbach near Siegen, his father of the same name (1753–1823) was a forest manager in the women's monastery in Keppel. After the one-year examination, he attended the forestry academy in Fulda from 1818 to 1819, where he passed the forestry candidate examination. He later turned to surveying.

After passing his surveyor's examination, Vorlaender entered the Prussian civil service and began working at the Royal Plan Chamber in Arnsberg in 1820. There he was initially entrusted with surveying work in the County of Limburg. In 1823 he became a cadastral surveyor. From 1823 to 1824 he did one year of military service with the 13th. Infantry Regiment in Münster.

He was then given responsibility for the cadastral system in the Minden administrative district, where he was appointed chief surveyor in 1828. His main task was to manage the re-measurement of the property tax register, which was necessary because up to that time property tax was determined based on the property owners' self-assessment. After completing the cadastral survey, Vorländer was entrusted with the continuation of the cadastral for the Minden government in 1834 and was appointed a member of the examination commission for surveyors. One of his students was the geodesist Friedrich Gustav Gauß.

During his work on the cadastre, Vorlaender discovered considerable lack of accuracy in determining the state survey points 1. and 2. Order from the previous state surveys, which were intended to form the basis for the cadastral system. Vorländer therefore undertook his own large-scale survey on his own initiative, which he linked to the Hanover state survey carried out by Carl Friedrich Gauß. Vorländer also used Gaussian working and calculation methods. Determining the trigonometric points 1. Order was not part of his area of ​​responsibility, which is why he had to do this work alongside his other tasks and received no support from his superior authority. At his own expense, he purchased a theodolite suitable for state surveying and a heliotrope from the Breithaupt company in Kassel. The work extended not only to the Minden administrative district, but also to the Principality of Lippe and parts of the Münster administrative district.

As a practical result, the national borders between Prussia and the Kingdom of Hanover, the Duchy of Braunschweig and the Principality of Waldeck were determined more precisely and a special map of the districts of the Minden administrative district and an overview map of the entire administrative district were created. He also made a special map and an overview map of the Weser. Until coordinates were provided by the Prussian State Survey, Vorländer's trigonometric points 1 were used. and 2. Order as the basis of the maps and the cadastre.

As a trained forestry official, he denounced the grievances in forest management in the Wiehengebirge, which he had noticed during survey work.

Vorlaender died on the 10th. March 1886 in Minden and was buried in the old cemetery. There is a memorial plaque on his former home on Königstrasse in Minden, and a street in the Bärenkämpen district is named after him.
