Raw data
Kitchin's Hampshire 1751 |
|
places & images |
Two sorts of raw data are offered for the study of Kitchin's map
of Hampshire, 1751.
- A comma delimited file of place name and position data.
- Image files of the map and feature 'layers'.
BEWARE: The image files can be large, from 50K up to
about 2.5Mbytes; you must decide which you want to access and save
on your local machine. Image sizes are given in the menu; two
figures correspond to two files accessed together.
|
registration & size
|
Each image has registration marks: upper left, lower left, lower right:-
upper left at SU05
lower left at SU00
lower right at SU80
The registration mark is at the origin of the grid square.
The set of images for this maker match each other in size,
scale, and orientation.
The same registration marks have been used for other maker's maps.
You will have to rotate maps by different makers to register
them together.
The distances apart of the registration marks, if they had been
marked on the original map are:-
width SU00 to SU80 is 430 mm
height SU00 to SU05 is 269 mm
grid 3.5 degrees clockwise.
|
| transparency |
The feature layer images, their label images, the ngr grid and
boundary images are 'transparent .gif' files (gif 89a with
the transparent layer colour index 255 pointing to
white 255,255,255).
|
| printing |
At 151 dpi the image files will printout at the original
size of the map.
|
| filenames |
The image file names have three parts:-
