Future Mapping Projects 
We intend to initiate Cadastral Mapping in our Country and are 
striving to find the best and most efficient methods for it’s implementation. 
Methods 
Aerotriangulation according to the Zeller-Brandenberger-Zarzicky 
method is employed in both a. m. mapping organisations. 
Survey of Israel prefers high-altitude photography for it’s purposes, 
the scale of these being 1 I 35,000 — 1 I 40,000. 
At the Photogrammetric Institute the scale of photography varies 
between 1 I 8000 and 1 I 25,000. 
Ground Control 
Control points are identified on the photographs and are marked on 
the ground before the flight only in exceptional cases. 
For small-scale mapping the position of the control points is deter 
mined with third-order accuracy, height is measured by vertical angle 
observations. 
For Large Scales levelled travers-points are used. 
Mapping Accuracy 
The required Mapping Accuracy is laid down in the State-Regulations 
for Topographic Mapping. 
For 1 : 20,000 scale the tolerance in Planimetry is: 0.2 mm., in Alti 
metry + 1.5 meter. 
The photogrammetrically plotted manuscripts are checked in the field 
and the necessary additions or alterations made. 
Instruments 
The first and second-order instruments used in our country are all 
manufactured by Wild (A5, A6, A8, E2). 
There are also some third-order instruments in use: Radial and 
Mahan plotters. 
Photo-Maps and Anaglyphs 
Photo-maps and Anaglyphs produced from enlarged Photographs are 
prepared by the Photogrammetric Institute, Jerusalem. 
The largest Photo-Map produced in our country is a big town’s Map 
in 1 1250 scale. 
Miscellaneous application of Aerial Photographs 
The Department of Soil Conservation of the Ministry of Agriculture, 
Government and Private Geologists, Oil-prospectors, Railway and Road 
Engineers, The Planning Department of the Ministry of the Interior and 
many others make extensive use of available Aerial Photographs, wherever 
applicable.
