Canada
This geodimeter was acquired from a Canadian branch of the manufacturer known as AGAtronics. Surveying Canada’s extensive and rugged territory has demanded sophisticated science and played a crucial role in the assessment and exploitation of our natural resources. The donor and his family immigrated to Canada in 1952 and moved to British Columbia in 1964. He was commissioned a British Columbia Land Surveyor in 1969 and the artifact was used extensively by him in the province’s Cariboo area until 1978 when he acquired a newer model to replace it. Ce géodimètre était acquis d'une branche du manufacturier canadien soue le nom AGAtronics. L'arpentage du Canada demande l'utilisation d'une science précise pour l'exploitation de nos ressources naturelles. Le donateur et sa famille ont immigré au Canada en 1952 et ont déménagé en Colombie-Britannique en 1964. Il est devenu un arpenteur-géomètre breveté de la province en 1969. L'artefact était utilisé dans la région Cariboo jusqu'à 1978 quand le donateur la remplacer par un modèle plus récent.
Function
This artifact used with a geodimeter to help calculate distances during the surveying of natural resources. Cet objet était utilisé avec un géodimètre pour faciliter la tâche de calculer des distances pendant la recherche et l’arpentage des ressources naturelles.
Technical
Model 6B likely came out around 1969 and was the first one with an orange finish rather than the earlier gray. This artifact represents a shift away from earlier instruments characterized by their mass and heft towards later ones that were so light they inspired the concept of the “total station”: a group of instruments mounted on a single tripod capable of making all of the usual surveying measurements. It was part of the first wave of lighter instruments using transistors. It also made use of of tungsten/mercury vapour lamps but they too would soon be superseded by the introduction of the laser, and then both microwave and infrared technology. Le Modèle 6B a probablement été conçus autour de l'année 1969 et il était le premier à avoir une finition orange au lieu du gris typique. L'artefact représente un changement ou un éloignement des instruments plus vieux qui était caractérisé par leur masse et grandeur. Le Modèle 6B étais non seulement plus léger, mais aussi une station complète sur un trépied capable de faire tout le mesurage nécessaire pour l'arpentage. L'objet faisait partie de la première vague à utiliser des transistors et des lampes à vapeur de tungstène/mercure, mais ils ont été remplacés par le laser et après par des micro-ondes et la technologie de l'infrarouge.

Finish
A rectangular artifact made of white synthetic material that could possibly be Bakelite. It has a series of scales that travel horizontally across both the front and back of the artifact. The scales have red and blue lettering. The middle portion of the rule can either be pulled or pushed to slide back and forth inside the rule itself. A transparent synthetic slide is attached to the rule with both metal screws and rivets and can be used to magnify the scales. Un artefact qui est rectangulaire et qui est fait avec un matériel synthétique qui est possiblement de la bakélite. L'objet a une série d'échelles qui voyagent à l'horizontale sur la face de l'artefact. Les échelles ont du lettrage rouge et bleu. Le milieu de la règle peut être poussé où tirer pour glisser à l'intérieur de l'objet. Un glisseur synthétique qui est transparente est attaché sur la règle avec des rivets et des vis et il peut être utilisé pour magnifier les échelles.
