Rules Governing the Avard of the Brock Gold Medal 
Preamble 
The periodic award of a go:d medal was instituted 
in 1952 by the |.S.P. to encourage the advancement of 
photogrammetry. The funds for the provision of medals 
were given in memory of Arthur and Norman Brock. 
On 22nd May 1954 and 25th March 1955 the Council 
of the I.S.P. adopted unanimously certain rules gover- 
ning the award of the medal and further resolved that 
those rules should remain in force until altered by the 
unanimous vote of the Council, which provision is 
still valid. On 8th May 1958 the Council considered 
alteration to the rules and subsequently by corresp- 
ondence agreed by unanimous vote to alter them and 
re-write them as follows. 
Rules governing the award of the Brock Gold Medal 
1. The medal shall be known as the Brock Gold 
Medal and shall be awarded at the sole discretion of 
the Couneil of the 1.S.P. which shall be exercised in 
accordance with the following rules. 
2. The person to whom the award is to be made 
shall be selected irrespective of his nationality and 
solely in respect of his contribution to the accom- 
plishment to be signalised by the award. 
3. The medal shall be awarded only in respect of 
an outstanding landmark in the evolution of photo- 
grammetry, which shall be a proven contribution to 
photogrammetry of whatever form, whether a major 
completed photogrammetric mapping project, some 
fundamentally new equipment or fundamentally new 
technique, or other new departure. 
4. The landmark in the evolution of photogram- 
metry to be thus signalised by the award of the 
medal shall have proved its worth as a contribution 
to photogrammetry at least two years prior to the 
congress at which the award is to be made and in 
general not more than some twelve years prior that 
congress. 
5. Recommendations for the award of the medal 
shall be made in accordance with the following rules: 
a) As a preliminary informative procedure, intend- 
ed solely to reduce the possibility of overlooking 
the names of possible candidates, the Administration 
shall, two years prior to each congress, invite the 
member societies to submit the names of those 
whose work lies directly within their cognizance and 
in their opinion might possibly fall within the scope 
of the award. No recommendations shall accompany 
such names, but a brief statement showing the field 
in which the person has been working and the gen- 
eral nature of his work therein may do so. The Ad- 
ministration shall send to all member societies with- 
out comment a list of all names and accompanying 
statements received up to 18 months prior to the 
congress. This list need not be and shall not be dee- 
med to be comprehensive of all possible candidates. 
Inclusion in it shall not be a prerequisite for recom- 
mendation for the award. 
b) Every recommendation for the award shall be made 
by two sponsors who shall be individuals adhering 
to the 1.S.P. through any of the forms of membership 
and who are not of the same nationality as their 
216 
candidate nor of the same nationality as one another. 
c) Recommendations shall be in respect of an in- 
dividual and not of a group of individuals nor of any 
organisation or commercial firm. However, as many 
advances in photogrammetry and in the execution 
of photogrammetric mapping projects may be largely 
due to team work, it shall be allowable to recommend 
the leader or the leading spirit of a team of workers, 
or such person as the team itself may think has made 
the most important or outstanding or fundamental 
contribution to their work. 
d) Every recommendation shall be made in writing 
to the President of the I. S. P. and shall be accom- 
panied by a documentation and explanation of the 
grounds of the recommendation which shall be suf- 
ficiently full to enable the Council to evaluate them. 
e) The sponsors may consult the photogrammetric 
organisations or individuals of the country in which 
their candidate has been working and, if they do so, 
tey must include in their documentation the advice 
they have received. 
f) Recommendations shall be made only during 
the period between the close of one congress and 
nine months before the opening of the next. 
g) All recommendations made prior to one con- 
gress shall lapse at the conclusion of that congress, 
whether or not any medal was awarded at it. It is 
permissible to revive a recommendation that has 
lapsed by making a fresh recommendation. 
6. The selection of the person to receive the medal 
shall be made by the Council in accordance with the 
following rules: 
a) Any member of the Council who has himself 
been recommended for the award shall not, while 
his name remains one that can still come up for con- 
sideration, take any part in the proceedings of selec- 
tion or be accounted a member of Council for the 
purpose of calculating the proportion of votes cast 
under this rule. 
b) Nine months before each congress the Council 
shall commence to consider all recommendations 
received to date, and may at the same time consider 
the merits of the work of any other person whom- 
soever, except a member of Council, that the Council 
itself deems worthy of consideration for the award. 
The Council shall complete their consideration and 
reach their conclusion in sufficient time to permit 
the preparation of the medal and its presentation at 
the Congress. 
c) The Council may use whatever procedure it 
thinks fit to reach its conclusions, provided the final 
selection is made by vote. In such voting a councillor 
of the same nationality as a candidate not yet elimi- 
nated shall have no vote and a candidate to be suc- 
cessful must receive the votes of not less than two 
thirds of those entitled to vote. Votes may be cast 
in person or by post. 
7. The Council shall normally expect to award one 
medal at each congress. It may abstain from awarding 
a medal at any particular congress, in which case it 
may award an additional medal at the congress next 
following but not later.
