MAP, a representation, on a plane and a reduced scale, of part or the

whole of the earth's surface. If specially designed to meet the

requirements of seamen it is called a chart, if on an exceptionally

large scale a plan. The words map and chart are derived from _mappa_ and

_charta_, the former being the Latin for napkin or cloth, the latter for

papyrus or parchment. Maps were thus named after the material upon which

they were drawn or painted, and it should be noted that even at present

maps intended for use in the open air, by cyclists, military men and

others, are frequently printed on cloth. In Italian, Spanish and

Portuguese the word _mappa_ has retained its place, by the side of

_carta_, for marine charts, but in other languages both kinds of maps[1]

are generally known by a word derived from the Latin _charta_, as

_carte_ in French, _Karte_ in German, _Kaart_ in Dutch. A chart, in

French, is called _carte hydrographique, marine or des côtes_; in

Spanish or Portuguese _carta de marear_, in Italian _carta da navigare_,

in German _Seekarte_ (to distinguish it from _Landkarte_), in Dutch

_Zeekaart_ or _Paskaart_. A chart on Mercator's projection is called

_Wassende graadkaart_ in Dutch, _carte réduite_ in French. Lastly, a

collection of maps is called an atlas, after the figure of Atlas, the

Titan, supporting the heavens, which ornamented the title of Lafreri's

and Mercator's atlases in the 16th century.

_Classification of Maps._--Maps differ greatly, not only as to the scale

on which they are drawn, but also with respect to the fullness or the

character of the information which they convey. Broadly speaking, they

may be divided into two classes, of which the first includes

topographical, chorographical and general maps, the second the great

variety designed for special purposes.

Topographical maps and plans are drawn on a scale sufficiently large to

enable the draughtsman to show most objects on a scale true to

nature.[2] Its information should not only be accurate, but also

conveyed intelligibly and with taste. Exaggeration, however, is not

always to be avoided, for even on the British 1 in. ordnance map the

roads appear as if they were 130 ft. in width.

Chorographical (Gr. [Greek: chôra], country or region) and general maps

are either reduced from topographical maps or compiled from such

miscellaneous sources as are available. In the former case the

cartographer is merely called upon to reduce and generalize the

information given by his originals, to make a judicious selection of

place names, and to take care that the map is not overcrowded with names

and details. Far more difficult is his task where no surveys are

available, and the map has to be compiled from a variety of sources.

These materials generally include reconnaissance survey of small

districts, route surveys and astronomical observations supplied by

travellers, and information obtained from native sources. The compiler,

in combining these materials, is called upon to examine the various

sources of information, and to form an estimate of their value, which he

can only do if he have himself some knowledge of surveying and of the

methods of determining positions by astronomical observation. A

knowledge of the languages in which the accounts of travellers are

written, and even of native languages, is almost indispensable. He ought

not to be satisfied with compiling his map from existing maps, but

should subject each explorer's account to an independent examination,

when he will frequently find that either the explorer himself, or the

draughtsman employed by him, has failed to introduce into his map the

whole of the information available. Latitudes from the observations of

travellers may generally be trusted, but longitudes should be accepted

with caution; for so competent an observer as Captain Speke placed the

capital of Uganda in longitude 32° 44´ E., when its true longitude as

determined by more trustworthy observations is 32° 26´ E., an error of

18´. Again, on the map illustrating Livingstone's "Last Journals" the

Luapula is shown as issuing from the Bangweulu in the north-west, when

an examination of the account of the natives who carried the great

explorer's remains to the coast would have shown that it leaves that

lake on the south.

The second group includes all maps compiled for special purposes. Their

variety is considerable, for they are designed to illustrate physical

and political geography, travel and navigation, trade and commerce, and,

in fact, every subject connected with geographical distribution and

capable of being illustrated by means of a map. We thus have (1)

physical maps in great variety, including geological, orographical and

hydrographical maps, maps illustrative of the geographical distribution

of meteorological phenomena, of plants and animals, such as are to be

found in Berghaus's "Physical Atlas," of which an enlarged English

edition is published by J. G. Bartholomew of Edinburgh; (2) political

maps, showing political boundaries; (3) ethnological maps, illustrating

the distribution of the varieties of man, the density of population,

&c.; (4) travel maps, showing roads or railways and ocean-routes (as is

done by Philips' "Marine Atlas"), or designed for the special use of

cyclists or aviators; (5) statistical maps, illustrating commerce and

industries; (6) historical maps; (7) maps specially designed for

educational purposes.

_Scale of Maps._--Formerly map makers contented themselves with placing

upon their maps a linear scale of miles, deduced from the central

meridian or the equator. They now add the proportion which these units

of length have to nature, or state how many of these units are contained

within some local measure of length. The former method, usually called

the "natural scale," may be described as "international," for it is

quite independent of local measures of length, and depends exclusively

upon the size and figure of the earth. Thus a scale of 1:1,000,000

signifies that each unit of length on the map represents one million of

such units in nature. The second method is still employed in many cases,

and we find thus:--

1 in. = 1 statute mile (of 63,366 in.) corresponds to 1 : 63,366

6 in. = 1 " " " " 1 : 10,560

1 in. = 5 chains (of 858 in.) " 1 : 4,890

1 in. = 1 nautical mile (of 73,037 in.) " 1 : 73,037

1 in. = 1 verst (of 42,000 in.) " 1 : 42,000

2 Vienna in. = 1 Austrian mile (of

288,000 in.) " 1 : 144,000

1 cm. = 500 metres (of 100 cm.) " 1 : 50,000

In cases where the draughtsman has omitted to indicate the scale we can

ascertain it by dividing the actual length of a meridian degree by the

length of a degree measure upon the map. Thus a degree between 50° and

51° measures 111,226,000 mm.; on the map it is represented by 111 mm.

Hence the scale is 1:1,000,000 approximately.

The linear scale of maps can obviously be used only in the case of maps

covering a small area, for in the case of maps of greater extension

measurements would be vitiated owing to the distortion or exaggeration

inherent in all projections, not to mention the expansion or shrinking

of the paper in the process of printing. As an extreme instance of the

misleading character of the scale given on maps embracing a wide area we

may refer to a map of a hemisphere. The scale of that map, as determined

by the equator or centre meridian, we will suppose to be 1:125,000,000,

while the encircling meridian indicates a scale of 1:80,000,000; and a

"mean" scale, equal to the square root of the proportion which the area

of the map bears to the actual area of a hemisphere, is 1:112,000,000.

In adopting a scale for their maps, cartographers will do well to choose

a multiple of 1000 if possible, for such a scale can claim to be

international, while in planning an atlas they ought to avoid a needless

multiplicity of scales.

_Map Projections_ are dealt with separately below. It will suffice

therefore to point out that the ordinary needs of the cartographer can

be met by conical projections, and, in the case of maps covering a wide

area, by Lambert's equal area projection. The indiscriminate use of

Mercator's projection, for maps of the world, is to be deprecated owing

to the inordinate exaggeration of areas in high latitudes. In the case

of topographical maps sheets bounded by meridians and parallels are to

be commended.

The meridian of Greenwich has been universally accepted as the initial

meridian, but in the case of most topographical maps of foreign

countries local meridians are still adhered to--the more important among

which are:--

Paris (Obs. nationale) 2° 20´ 14´´ E. of Greenwich.

Pulkova (St Petersburg) 30° 19´ 39´´ E. "

Stockholm 18° 3´ 30´´ E. "

Rome (Collegio Romano) 12° 28´ 40´´ E. "

Brussels (Old town) 4° 22´ 11´´ E. "

Madrid 3° 41´ 16´´ W. "

Ferro (assumed) 20° 0´ 0´´ W. of Paris.

The _outline_ includes coast-line, rivers, roads, towns, and in fact all

objects capable of being shown on a map, with the exception of the hills

and of woods, swamps, deserts and the like, which the draughtsman

generally describes as "ornament." Conventional signs and symbols are

universally used in depicting these objects.

[Illustration: FIG. 1.]

_Delineation of the Ground._--The mole-hills and serrated ridges of

medieval maps were still in almost general use at the close of the 18th

century, and are occasionally met with at the present day, being cheaply

produced, readily understood by the unlearned, and in reality preferable

to the uncouth and misleading hatchings still to be seen on many maps.

Far superior are those scenographic representations which enable a

person consulting the map to identify prominent landmarks, such as the

Pic du Midi, which rises like a pillar to the south of Pau, but is not

readily discovered upon an ordinary map. This advantage is still fully

recognized, for such views of distant hills are still commonly given on

the margin of marine charts for the assistance of navigators; military

surveyors are encouraged to introduce sketches of prominent landmarks

upon their reconnaissance plans, and the general public is enabled to

consult "Picturesque Relief Maps"--such as F. W. Delkeskamp's

_Switzerland_ (1830) or his _Panorama of the Rhine_. Delineations such

as these do not, however, satisfy scientific requirements. All objects

on a map are required to be shown as projected horizontally upon a

plane. This principle must naturally be adhered to when delineating the

features of the ground. This was recognized by J. Picard and other

members of the Academy of Science whom Colbert, in 1668, directed to

prepare a new map of France, for on David Vivier's map of the environs

of Paris (1674, scale 1:86,400) very crude hachures bounding the rivers

have been substituted for the scenographic hills of older maps. Little

progress in the delineation of the ground, however, was made until

towards the close of the 18th century, when horizontal contours and

hachures regulated according to the angle of inclination of all slopes,

were adopted. These contours intersect the ground at a given distance

above or below the level of the sea, and thus bound a series of

horizontal planes (see fig. 1). Contours of this kind were first

utilized by M. S. Cruquius in his chart of the Merwede (1728); Philip

Buache (1737) introduced such contours or isobaths (Gr. [Greek: isos],

equal; [Greek: bathys], deep) upon his chart of the Channel, and

intended to introduce similar contours or isohypses ([Greek: hypsos],

height) for a representation of the land. Dupain-Triel, acting upon a

suggestion of his friend M. Ducarla, published his _La France considérée

dans les différentes hauteurs de ses plaines_ (1791), upon which

equidistant contours at intervals of 16 toises found a place. The

scientific value of these contoured maps is fully recognized. They not

only indicate the height of the land, but also enable us to compute the

declivity of the mountain slopes; and if minor features of ground lying

between two contours--such as ravines, as also rocky precipices and

glaciers--are indicated, as is done on the Siegfried atlas of

Switzerland, they fully meet the requirements of the scientific man, the

engineer and the mountain-climber. At the same time it cannot be denied

that these maps, unless the contours are inserted at short intervals,

lack graphic expression. Two methods are employed to attain this: the

first distinguishes the strata or layers by colours; the second

indicates the varying slopes by shades or hachures. The first of these

methods yields a hypsographical, or--if the sea-bottom be included, in

which case all contours are referred to a common datum line--a bathy

hypsographical map. Carl Ritter, in 1806, employed graduated tints,

increasing in lightness on proceeding from the lowlands to the

highlands; while General F. von Hauslab, director of the Austrian

Surveys, in 1842, advised that the darkest tints should be allotted to

the highlands, so that they might not obscure details in the densely

peopled plains. The desired effect may be produced by a graduation of

the same colour, or by a polychromatic scale--such as white, pale red,

pale brown, various shades of green, violet and purple, in ascending

order. C. von Sonklar, in his map of the Hohe Tauern (1:144,000; 1864)

coloured plains and valleys green; mountain slopes in five shades of

brown; glaciers blue or white. E. G. Ravenstein's map of Ben Nevis

(1887) first employed the colours of the spectrum, viz. green to brown,

in ascending order for the land; blue, indigo and violet for the sea,

increasing in intensity with the height or the depth. At first

cartographers chose their colours rather arbitrarily. Thus Horsell, who

was the first to introduce tints on his map of Sweden and Norway

(1:600,000; 1835), coloured the lowlands up to 300 ft. in green,

succeeded by red, yellow and white for the higher ground; while A.

Papen, on his hypsographical map of Central Europe (1857) introduced a

perplexing range of colours. At the present time compilers of strata

maps generally limit themselves to two or three colours, in various

shades, with green for the lowlands, brown for the hills and blue for

the sea. On the international map of the world, planned by Professor A.

Penck on a scale of 1:1,000,000, which has been undertaken by the

leading governments of the world, the ground is shown by contours at

intervals of 100 metres (to be increased to 200 and 500 metres in

mountainous districts); the strata are in graded tints, viz. blue for

the sea, green for lowlands up to 300 metres, yellow between 300 and 500

metres, brown up to 2000 metres, and reddish tints beyond that height.

[Illustration: FIG. 2.]

The declivities of the ground are still indicated in most topographical

maps by a system of strokes or hachures, first devised by L. Chr. Müller

(_Plan und Kartenzeichnen_, 1788) and J. G. Lehmann, who directed a

survey of Saxony, 1780-1806, and published his _Theorie der

Bergzeichnung_ in 1799. By this method the slopes are indicated by

strokes or hachures crossing the contour lines at right angles, in the

direction of flowing water, and varying in thickness according to the

degree of declivity they represent (cf. for example, the map of

SWITZERLAND in this work). The light is supposed to descend vertically

upon the country represented, and in a true scale of shade the intensity

increases with the inclination from 0° to 90°; but as such a scale does

not sufficiently differentiate the lesser inclinations which are the

most important, the author adopted a conventional scale, representing a

slope of 45° or more, supposed to be inaccessible, as absolutely black,

the level surfaces, which reflect all the light which falls upon them,

as perfectly white, and the intervening slopes by a proportion between

black and white, as in fig. 2. The main principles of this system have

been maintained, but its details have been modified frequently to suit

special cases. Thus the French survey commission of 1828 fixed the

proportion of black to white at one and a half times the angle of slope;

while in Austria, where steep mountains constitute an important feature,

solid black has been reserved for a slope of 80°, the proportion of

black to white varying from 80:0 (for 50°) to 8:72 (for 5°). On the map

of Germany (1:100,000) a slope of 50° is shown in solid black while

stippled hachures are used for gentle slopes up to 10°. Instead of

shading lines following the greatest slopes, lines following the

contours and varying in their thickness and in their intervals apart,

according to the slope of the ground to be represented, may be

employed. This method affords a ready and expeditious means of sketching

the ground, if the draughtsman limits himself to characteristically

indicating its features by what have been called "form lines." This

method can be recommended in the case of plotting the results of an

explorer's route, or in the case of countries of which we have no

regular survey (cf. the map of AFGHANISTAN in this work).

Instead of supposing the light to fall vertically upon the surface it is

often supposed to fall obliquely, generally at an angle of 45° from the

upper left-hand corner. It is claimed for this method that it affords a

means of giving a graphic representation of Alpine districts where other

methods of shading fail. The Dufour map of Switzerland (1:100,000) is

one of the finest examples of this style of hill-shading. For use in the

field, however, and for scientific work, a contoured map like

Siegfried's atlas of Switzerland, or, in the case of hilly country, a

map shaded on the assumption of a vertical light, will prove more useful

than one of these, notwithstanding that truth to nature and artistic

beauty are claimed on their behalf.

Instead of shading by lines, a like effect may be produced by mezzotint

shading (cf. the map of ITALY, or other maps, in this work, on a similar

method), and if this be combined with contour lines very satisfactory

results can be achieved. If this tint be printed in grey or brown,

isohypses, in black or red, show distinctly above it. The same

combination is possible if hills engraved in the ordinary manner are

printed in colours, as is done in an edition of the 1-inch ordnance map,

with contours in red and hills hachured in brown.

Efforts have been made of late years to improve the available methods of

representing ground, especially in Switzerland, but the so-called

stereoscopic or relief maps produced by F. Becker, X. Imfeld, Kümmerly,

F. Leuzinger and other able cartographers, however admirable as works of

art, do not, from the point of utility, supersede the combination of

horizontal contours with shaded slopes, such as have been long in use.

There seems to be even less chance for the combination of coloured

strata and hachures proposed by K. Peucker, whose theoretical

disquisitions on aerial perspective are of interest, but have not

hitherto led to satisfactory practical results.[3]

The above remarks apply more particularly to topographic maps. In the

case of general maps on a smaller scale, the orographic features must be

generalized by a skilful draughtsman and artist. One of the best modern

examples of this kind is Vogel's map of Germany, on a scale of

1:500,000.

_Selection of Names and Orthography._--The nomenclature or "lettering"

of maps is a subject deserving special attention. Not only should the

names be carefully selected with special reference to the objects which

the map is intended to serve, and to prevent overcrowding by the

introduction of names which can serve no useful object, but they should

also be arranged in such a manner as to be read easily by a person

consulting the map. It is an accepted rule now that the spelling of

names in countries using the Roman alphabet should be retained, with

such exceptions as have been familiarized by long usage. In such cases,

however, the correct native form should be added within brackets, as

Florence (Firenze), Leghorn (Livorno), Cologne (Cöln) and so on. At the

same time these corrupted forms should be eliminated as far as possible.

Names in languages not using the Roman alphabet, or having no written

alphabet should be spelt phonetically, as pronounced on the spot. An

elaborate universal alphabet, abounding in diacritical marks, has been

devised for the purpose by Professor Lepsius, and various other systems

have been adopted for Oriental languages, and by certain missionary

societies, adapted to the languages in which they teach. The following

simple rules, laid down by a Committee of the Royal Geographical

Society, will be found sufficient as a rule; according to this system

the vowels are to be sounded as in Italian, the consonants as in

English, and no redundant letters are to be introduced. The diphthong

_ai_ is to be pronounced as in _aisle_; _au_ as _ow_ in _how_; _aw_ as

in _law_. _Ch_ is always to be sounded as in _church_, _g_ is always

hard; _y_ always represents a consonant; whilst _kh_ and _gh_ stand for

gutturals. One accent only is to be used, the acute, to denote the

syllable on which stress is laid. This system has in great measure been

followed throughout the present work, but it is obvious that in numerous

instances these rules must prove inadequate. The introduction of

additional diacritical marks, such as [macron mark] and [breve mark],

used to express quantity, and the diaeresis, as in _aï_, to express

consecutive vowels, which are to be pronounced separately, may prove of

service, as also such letters as _ä_, _ö_ and _ü_, to be pronounced as

in German, and in lieu of the French _ai_, _eu_ or _u_.

The United States Geographic Board acts upon rules practically identical

with those indicated, and compiles official lists of place-names, the

use of which is binding upon government departments, but which it would

hardly be wise to follow universally in the case of names of places

outside America.
