A PAPER LANDSCAPE: THE ORDNANCE SURVEY IN NINETEENTH CENTURY IRELAND

Auteur :
ANDREWS J. H.,

Description :
THE ORDNANCE SURVEY IN IRELAND IS UNUSUAL IN THE GREAT WEALTH OF ITS SURVIVING HISTORICAL DOCUMENTS (MOST OF THE EQUIVALENT MATERIAL FOR THE BRITISH ORGANIZATION HAS BEEN LOST). THIS EVIDENCE THROWS LIGHT ON THE WAY DECISIONS WERE TAKEN IN SUCH ORGANIZATIONS, AND SHOWS HOW IMPORTANT A KNOWLEDGE OF SURVEY HISTORY IS TO CHOSE WHO USE THE MAPS AS SOURCES OF TOPOGRAPHICAL INFORMATION. FOUNDED IN 1771, THE ORDNANCE SURVEY WAS DIRECTED IN 1824 TO MAP IRELAND (FOR THE PURPOSE OF A VALUATION OF LAND AND BUILDINGS) ON THE LARGE SCALE OF SIX INCHES TO THE MILE. ECONOMY AND ACCURACY WERE EVENTUALLY ACHIEVED BY MEANS OF A COMPLEX SYSTEM OF CARTOGRAPHIC OPERATIONS, OUTDOOR AND INDOOR, WHICH CROSS-CHECKED ONE ANOTHER. THE SIX-INCH MAPS APPEARED BETWEEN 1835 AND 1846| THEIR REVISION BEGAN IN 1844, AND PRODUCTION OF BOTH SMALLER AND LARGER-SCALE MAPS CONTINUED UNTIL ALMOST THE END OF THE CENTURY. THIS ACCOUNT DEALS ALSO WITH MORE RECENT ASPECTS OF IRISH SURVEY HISTORY, INCLUDING THE DEVELOPMENT OF CADESTRAL MAPS ON THE SCALE OF 1/2500 WHICH WERE AUTHORIZED IN 1887.
