section of the Public Works Department used these aerial photographs of the 
Negev for a geological interpretation and the prospecting permits were granted 
accordingly. 
“This work was done by the late G. S. Blake, later on by S. H. Shaw and 
Major A. Gluck. 
In 1936, Mr. Zalman Leef (Lifshitz) a well known Israeli surveyor and 
agricultural engineer, came to the conclusion that remapping was necessary to 
meet the needs of the country’s development and consequently he began to gather 
information from European countries concerning photogrammetry. In 1938 he 
participated in an international course on Photogrammetry at the Technical 
High School of Zurich in order to complete his knowledge in this science and 
with the intention to start later on a photogrammetric institute in Israel. In 
1939 he performed test flights in the Carmel Mountain range and so started to 
work with graphical plotting. This work was interrupted with the outbreak of 
the Second World-War and the whole scheme had to be abandoned, as it became 
impossible to secure the necessary aircraft and instruments. 
In 1942 the 524 (all- Jewish) Field Survey Company was established within 
the British Army. Major Gluck was taken as one of the officers and later be- 
came O.C. of the company. 
The company started with 120 men and developed later to 290 men. After 
a year of training, they did air-survey in the Middel-East and the C.M.F. com- 
mand. With the end of hostilities a small group of people from the 524 Com- 
pany joined together under the leadership of the late Zalman Leef (Lifshitz) and 
started to plan photogrammetric work in large scales. In early 1948 they began 
mapping extensive areas from air photographs taken by the R.A.F. in 1 : 10,000 
scale with contour intervals of 5 m by Aroundel method. In the meantime, Mr. 
Leef (Lifshitz) went to the U.S.A. and to Switzerland and made there experi- 
ments and investigations in order to find out the instruments with which to 
equip the institute. In early 1949 decision was taken and the Photogrammetric 
Institute, Jerusalem, was established and commenced work with the aid of mod- 
ern instruments, in order to meet the many needs of the State of Israel in sur- 
vey and planning of the country. 
Already in 1948/49 during the hostilities between Israel and the Arab 
States, the trained people had been called up for the preparation of up-to-datc 
small scale maps and other photogrammetrical work in connection with this 
warfare, and a small Airsurvey Section was established in the Government 
Survey Department. 
In September 1949 the Photogrammetric Institute started photographing 
extensive areas in Israel with a Wild RC-5 aerial camera, assisted by a K.L.M. 
aircraft. At the same time, as the photographs came off, exact mapping work 
commenced in the Institute under the technical management of the late Z. Leef 
(Lifshitz) assisted by Major A. Gluck. The first maps prepared were in 1 : 5000 
scale, but later on mostly a scale of 1 : 2500 and 1 : 1000 with contour intervals 
of 1 m was adopted. 
Since then the Institute shows a yearly output of approximately 1000 sqkm 
of mapped area in the above-mentioned scales, with Wild-A5 and A6 Sterero- 
plotters. 
In 1951 new aerial photography was started, but without the help of 
foreign firms.
