Abstract--A computer program is described for the datum change of geographical coordinates over large areas. The transformation to geocentric coordinates and ordinary least-squares techniques are applied to a set of coordinates of points (minimum three) in the two reference systems. The parameters of rotation, translation, and scaling between the two ellipsoids are output, and are suitable to be tabulated to provide for further shifting of data in the same area. The results indicate that accuracies of a few meters can be achieved over an entire country by using a single set of parameters. Higher accuracies may be obtained by local conversion procedures. The program also is used for accurate direct and inverse geographical-to- metric coordinate conversion for nine most used mapping projections. Mathematical expressions and the FORTRAN 77 source listing are provided.
Key Words: Datum change, Geographical coordinates, Cartography.
INTROI)UCYION
A cartographic datum (Snyder. 1982) is characterized by the geometry of the selected ellipsoid (its semi- major axis and amount of flattening) and by its orientation, that is the adoption of an initial point where the ellipsoid is forced to be tangent to the geoid. From these initial points National Topographic Sys- tems (NTS) depart. Because good quality cartography is linked to NTS, attention must be paid to the errors that occur when processing geographical coordinates originated from different reference systems. The most frequent situations of error arise when digitizing maps. whose data are linked to a different datum, or when acquiring positioning data from instruments such as satellite or other precision navigation systems. where each of the latter are linked to some local or global datum
To homogenize data, one should be able to shift the original data to another reference system. The transfer of data to a different cartographic datum must entail a good accuracy even at large-scale ap- plications (1:10.000. for example) and the possibility to apply the same procedure over large regions, for example an entire country.
From specialized literature some fast datum change procedure can be determined, such as the abridged Molodenskji formula (International Hydro- graphic Organization. 1983), or the procedures of Vincenty (1965) and Born ford ( 1971 ). However, it was thought that they were not applicable to large-scale cartography, because the errors are larger than the graphic precision (Bortoluzzi and Ligi. 1986, 1987). In contrast, extremely accurate shift procedures can be
performed only by Geodetic Surveys or specialists, because they involve long computations and the ac- cess to large data sets of geodetic information.
However, good precision can be achieved with simpler methods even for large areas, if assumptions are made for the acceptable errors. Because we are concerned with map and cartographic data for geolo- gical and geophysical uses, we focused on obtaining accuracies that approach graphic precision when working with I: 10,000 maps (at this scale the graphic precision of 0.2 mm brings a real precision of 2 m). Further. we pointed at procedures suitable to be used by inexperienced people.
in this paper we present DATUM, an interactive computer program that shifts geographical data among different reference systems, provided that the coordinates in the two systems of at least three points are known. These latter points can be both high- precision geodetic information provided by official agencies, or they can be obtained in published maps. As an example, the Italian official state cartography at 1:50,000 and the regional cartography at I:10.000 give the corner coordinates both in the European Datum of 1950 (ED50) and in the Italian National Topographic System (INTS) (Pericoli, 1971).
METHODS
Shifting of geographical coordinates to another reference system is a problem of rototranslating and scaling one ellipsoid to another. Under general assumptions this problem may be solved by using either curvilinear or rectangular 3-D (geocentric) coordinates. Morever, Cartesian coordinates are use-

able if one works in the conformal plane, as for exam- ple with the affine transformation of homogeneous coordinates in the Universal Transverse Mercator (UTM) system (Bortoluzzi and Ligi, 1987).
The method we present performs a geometrical rototranslation of the (xt, x:, x,) rectangular geo- centric coordinates associated with ellipsoidal latitude and longitude (4~. ~). These relations (Bomford. 1971J are:
= (N + h) eos4~ sin,{ (I)
"c [(1 - - e 2 ) N + h I sin¢/~
{ ~. = tan ~ i.v:,'xt)
4~ = tan '[(xs + e:N sin~b)/,~/(.~ + xi)l (2)
h = .x~sec2sec,;b - N
= X2 cosec2 secq5 -- N
where N is the radius of curvature in the prime verti- cal. h is the height above the ellipsoid, and e is the eccentricity of the ellipsoid. In Equation (2). 0 is obtained by a rapidly convergent iterative process.
Relations of Equations ( I ) and (2) represent ;, one-to-one correspondence between geographical and rectangular coordinates. They suggest that simpler transformations may relate the coordinates of a point in any three right-handed rectangular Cartesian re- ference systems

where (for i = I, 2, 3 a n d j = I, 2, 3), S~ are the scaling parameters, g,j are the direct ion cosines o f angles between axes x~ and %, and xo are the or igin coordinates of the x, system with respect to the origin of the x~.
The rotation matrix is orthogonat, and the direc- tion cosines g,, are function only of the rotation angles 0~, 0:, 0~, and are computed by:

where (for k = I, 2, 3) a~ = sin(0~) and & = cos (0~).
The parameters O s, S s, and xoj are unknown in Equation (3); they can be estimated by least-squares procedure if the coordinates o f m points (m /> 3) are known in the two reference systems. From Equation (3). any point provides the residual:
i = g , S (~ - ~,,i - ~ = 0 (5)
for i = 1. 2, 3. that yields a system of nonlinear equat ions
We assume that the differences between the tv, o ellipsoids are small, therefore the initial approximate values of the unknowns can be set (for i = 1, 2. 3): 0 , = O: S.* = I g* = 0
By Taylor's expansion of Equat,on (5) and con- sidering only' the first-degree polynomial approxima- tion. we obtain:

where A0, = /), - 0/*. AS~ = 5~. - S~, Ax,, z -%*,-
This yields a linear system ofthree m equations with unknowns A0,. AS,, 3.%. that is solved by the least- sqt, ares method. The so(u/ions obtained provide cor- rections for the initial guesses ((./~ S,*, x,*). The suc- cessive approximate values arc estimated itcratively fronl Eqt,ation (6) and the process is repeated until the difference of the sum of the squares of l~ (k = I, 2. . . 3m) o f t h e n t h arid nth - I iterations islcss than a spccitied amount (in our work 1.0-~0).
By tabulating rototranslation parameters for any area, changes of datum (or of the reference system) is performed using relationships given by Equations (I), (3), and (2) (subroutines GEOXYZ, GCSHFT, X Y Z G E O ) ,
DESCRIPTION OF TIlE PROGRAM
Program DATUM is structured into three phases, and can be run in both interactive and batch mode (each user response in interactive mode is copied on a log file, that can be edited and resubmitted to the system). The program makes extensive use of win- dows and menus, to give the user maximum assistance while performing this task
Phase (I) is the datum shift and projection in- formation collection (Fig. A 1 ), User has the opportun- ity to select old and new datum among several of the most used continental and national cartographic re- ference systems throughout the world, such as the ED50, the North American Datum of 1927, the NTS's of France and Great Britain and many others, plus the World Geodetic System of 1972 (WGS72). This information was taken by International Hydro- graphic Organization (1983). For the geographical- to-metric direct and inverse coordinate conversion, selections are available among nine mapping projec- tions, such as the Direct and Oblique Mercator, the UTM, the Cassini-Soldner, the Polyconic, the Lam- bert Conformal and Azimuthal, the Albers and the Stereographic. Care was taken to provide the user
Datum shift and conversion of geographical coordinates 451
with the possibility to select among the different cartographic applications of the projection (Snyder, 1982). such as the polar and oblique aspects, or the two methods for mapping in the Lambert Conformal.
It also is possible to select between (a) speditive, less accurate, and (b) accurate shift.
Procedure (a) converts data to and from each tab- ulated datum by the abridged Molodenskij formula. and uses the geometrical differences of each spheroid toward the WGS72. The accuracy one can expect has to be calculated for each specific datum. For the conversion from the INTS to the ED50 an accuracy of 15-20m (Bortoluzzi and Ligi. 1987, 1988) has been determined.
The conversion to and from the WGS72 ellipsoid is important particularly when geographical data are acquired by satellite positioning systems.
Procedure (b) is performed by the method des- cribed in this paper. It requires the availability of ellipsoidal geographical coordinates (latitude, longi- tude, and height) for the control points within the area of interest: although not essential, it is preferable that these points were distributed uniformly. On the assumption that the differences between the height above the ellipsoid and the height above the geoid are small, the required two values can be set to the height above the geoid.
Phase (2) prompts the user to furnish input and output information regarding the conversion process (Fig. A2). In sequence one is allowed to select:
(a) Source of input, either keyboard or disk file; (b) Type of coordinates of input and output data:
latitude and longitude expressed as Degrees Minutes Seconds (DMS), or Degrees Minutes Hundredths (DMH), or Decimal Degrees (D60), or Centesimal Degrees (DI00), or Hours Minutes Seconds (HMS). or radians: the metric projection coordinates may be selected as well: should this latter selection occur, the user is prompted for input of the relevant projection parameter (Fig. A3);
(c) Position of variables latitude (Northing). lon- gitude (Easting), and height within the input file (if the UTM option was selected the UTM zone is required also): this is accomplished in a simple manner by marking the related fields on the first record of the user file as shown at the terminal (the program creates automatically the FORTRAN format for read and write operations, and on output, the new coordinates are overwritten in places of the old ones, preserving the content of the rest of the record:
(d) Coordinates of (I) the vertexes of the polygon that includes the area of interest or (2) of the center of the area: if the former option is selected, the program calculates the coordinates of the center of gravity of the area (Zarkos and Rogers, 1987). and includes all the calibration points that lie within the area (Salo- mon. 1978); conversely, if the latter option is selected, the program uses the ten control points closest to the given center of area, after having sorted them by increasing distance.
Phase (3) is the conversion phase, that in sequence outputs: (a) the computed shifts between the two spheroids, (b) the rototranslation parameters, and (c) the "'goodness-of-fit'" of the conversion, expressed as mean and standard deviation of the distances in meters from the original and recalculated coordinates of calibration points (Fig. A5). After this the con- version process takes place.
In addition to performing change of datum or geo- graphical-to-projection coordinate conversion, the program can be used to transform the format of geographical coordinates in input, that is to and from DMS, DMH, D60, DI00. HMS. and RAD. This is accomplished by selection of option NO SHIFT during phase (I).
Examples of the interaction during each separate phase can be seen in Appendix I.
RESULTS
The procedure has been tested by shifting points among the three cartographic systems currently avail- able in Italy: (a) the datum of 1909 (IGBE. with different origin points)(Boaga, 1960: Pericoli, 1971; Area. 1987). (b) the INTS (with origin point M. Mario, near Roma), and the ED50 (with origin point Postdam, near Bonn, F.R.G.). Ellipsoid parameters are the Bessel of 1841 for IGBE, and the International (Hayford of 1924) for INTS and ED50. These two letter datum are used for various scale accurate land topography, whereas IGBE is used for marine map- ping in some particular areas and for Regional Plane Coordinate networks.
The calibration and test data have been set up from: (I) the coordinates in the three systems of some first-order geodetic points distributed all over the country (accuracy to the nearest thousandth of a second) (see Figs. I, 2) (these data were provided by Divisione Geodetica of the Instituto Geografico Militare ltaliano and by lstituto ldrografico della Marina of Italy): (2) the corner coordinates of pub- lished maps at 1:50,000 and I: 10,000 scales (accuracy to the nearest meter). To get reliable statistics of goodness of conversion, the available control point data set were split in two data files. Each of these files has been used alternatively as calibration and test data. The output of several test runs of the program are summarized in Table I.
The results indicate that the method is accurate sufficiently for working at a rather large scale (i:25,000), even by using a single set of rototrans- lation parameters for the entire country.
The data presented in Table 1 show the consistent reduction of the conversion errors when the roto- translation parameters are computed within separate blocks. This is particularly the situation of the conver- sion from INTS to ED50. On the contrary, when converting from IGBE to INTS, the errors are deter- mined to be smaller over the whole country. This discrepancy is thought to be explained by the major

Examples of Interaction and Use o/" Program DATUM
An interaction at the terminal with DATUM is presented. Figure AI is the datum and projection selection mask: by moving the arrow keys the user can select datum and type of shift; the fields on the right rotate to show semimajor axis and reciprocal flattening of the selected spheroid. Figure A2 shows the input/output option menu. whereas Figure A3 presents the projection parameter window. Finally. Figure A5 illustrates the shift parameters and output phase mask.
For testing purposes, an example of calibration data set is shown in Table AI. The data must be converted to binary format for the published version of subroutine DATUMS. or the READ statement have to be changed accordingly. The results of the procedure when using the data set can be seen in Figures A4. A5 (shift is from INTS to ED50).

Implementation Problems and Source Listings
The program is coded in ANSI FORTRAN 77. The presented version runs on DEC VAX, IBM PC, and compatibles (Microsoft FORTRAN Compiler 4.0). Few low-level machine-dependent modules are inserted into the ANSI terminal management library, and their usage is explained throughout the software listing. Compiler directives must be changed to match system requirements accordingly. It has to be kept in mind that for MS-DOS installations, the ANSI driver is required for proper functioning. It is believed that the program should run on other installations, provided that the low-level operating system calls were replaced.
The listed code includes a reviewed version of part of the library published in Bortoluzzi and Ligi (1986), to correct small "bugs" and to improve efficiency. The modified software from Salomon 0978) and Zarkos (1988) is presented too.
The routine of least-square solution was taken by the published software of the CERN computer library, as available at CINECA (Centro di Calcolo dell'italia Nord Orientale, Bologna, Italy). Any other available routine such as those in the NAG or IMSL FORTRAN libraries performs the task as well as the one we used (the IMSL routine LLSQR was tested and gave the same results). This would save time when coding and probably would improve efficiency.
The software is available upon request from the authors. Distribution media could be MS-DOS diskette, or, preferably, DECNET or EARN.BITNET (L56BOCglt~ ICINECA2, GEOF1SICA(b~ASTBOI) electronic mail.
