Erslew.
Fransk geograf i slutet av 1700-talet. Det finns en rad enkla kartor av honom från åren 1753-91 men ingen hel atlas. Titeln geograf anger han själv på kartorna. Inga ytterligare upplysningar om honom har funnits, om han inte är identisk med Jean Francois Augustin Janvier de Flainville (1717-91), som var advokat till 1759, inspektör vid krigsakademin vid revolutionen 1789 och senare borgmästare i Chartres och dessutom känd arkeolog.

1600-73 - ARNOLD COLOM (son) c. 1624-68
Jacob Colom was a printer, bookseller, chart and globe maker who set out to challenge the virtual monopoly held by W. J. Blaeu, then the only chart maker in Amsterdam. His Pilot Guide De Vyerighe Colom published in various formats and languages (with exotic tides) to meet the demands of the time was highly successful and forced Blaeu to revise and enlarge his existing chart books. In spite of Blaeu's efforts, Colom's Guide remained popular with seamen for many years and although the charts were issued in great quantity, they are now extremely rare.

The old economic map
in the Region of Mälaren.
In connection with the enclose process (“laga skifte”) it was recommended
that a summary of the maps to generalized representation of whole parishes be
produced. This work was much furthered by the order that the parish maps could
serve as a sort of qualification works for surveyors. Summaries of the
enclosure maps were also put together as framework (“stomkartor”) both for
the topographic maps and for the economic maps that were drawn for "härad"
districts that consists of a group of parishes. The economic "härad"
maps were printed in the scale of 1:50 000 beginning with the maps of the
"härad" of Uppsala county (“län”) 1860. The economic maps of
Uppsala, Stockholm, Södermanland and Västmanland counties are here analyzed
as to their reliability as sources for geographical studies by means of a
comparison between the printed maps, the field maps (e.g. the revised "stomkartor")
and the underlying enclosure maps. The descriptions (“beskrivningar”)
belonging to the economic maps have been compared with official statistics
from the same years, if possible. As a result it can be said that the old
economic maps are well done and the field checking was very carefully
performed. Consequently the maps in question give a very fine synchronous view
of the regions. They should be more used by geographers, historians and
statisticians. Unfortunately all Sweden does not possess such maps.
