Uganda Airborne Data Dissemination Policy
Uganda Airborne Data Dissemination Policy
Uganda Airborne Data Dissemination Policy
Introduction
The High Resolution Airborne Geophysical Survey Programme involving
magnetic, radiometric and electromagnetic surveys that is aimed at assisting and
promoting mineral exploration commenced in December 2006.
The large volume of data and the increasing number of requests by mineral
investors and other interested parties for data windowed to their areas of interest
has necessitated the development of a data dissemination policy which will
eventually be transformed into a dedicated online data storage and management
system including a customised viewing, handling and archiving system.
The airborne geophysical management system shall store all grid and line
archives in a consistent format that guarantees data integrity and facilitates data
distribution. Where areas of interest encompass more than one survey, grid data
are supplied as individual survey grids and also as windowed supergrids.
Supergrids are compilations from all available high-resolution and regional data
and are upgraded regularlly as new survey data become available.
The current high resolution surveys followed the regional airborne geophysical
surveys for mineral exploration that was funded by United Nationas Development
Programme (UNDP) in 1961 and Government of Uganda in in1980 and achieved
almost 50% national coverage. These surveys were typically flown with 1 km line
spacing, 10 km ties and 120 m ground clearance. All magnetic data of the
regional programme were subsequently compiled into one consistent data set
merged during the African Magnetic Mapping Project in 1992. Therefore in
addition to the new high resolution airborne geophysical data, the regional
airborne geophysical data including magnetic and radiometric data are also
available for dissemination.
Due to industry demand, the Ministry of Energy and Mineral Development
(MEMD) and Department of Geological Survey and Mines (DGSM) may decide
to release certain airborne geophysical data in preliminary form. These data will
have been fully processed by Fugro Airborne Surveys, and reviewed
independently by DGSM’s quality control experts. The final products may contain
minor adjustments, and will include additional channels and grids. Any purchase
of preliminary data will include a copy of the final data for the same area when
those products are released.

ANNEX 2.
Grid data are delivered in Oasis Montaj Geosoft grid file format .
Line data are delivered in Oasis Montaj Geosoft format and ASCII file format and
a format description file accompanies each data file.
Data Windowing
Data shall generally be sold on the basis of standard topographical map sheets.
However, data can also be windowed to any boundary on request.
Payments
Complete digital magnetic and radiometric data (line data) are sold for Ug Shs 30
(1 US$ =Shs 3,500/=) per line-kilometre. In case of grids only the price is
calculated on the area covered by the data at Ug Shs 150 per km 2 for each grid
(magnetic and radiometric).
Geotiffs
Digital Geotiffs are produced from the Supergrids, which are compilations of all
high resolution and regional data available. Geotiffs are based on the standard
1:50.000 topographical map sheets and are sold at Ug Shs 10,000 per sheet, for
magnetics and Ug Shs 10,000 for radiometrics.
Electromagnetics
Electromagnetic data are sold for Ug Shs 300 per line-kilometre including grid
and line data.

* A shipping charge shall be included on the cost of data, especially for overseas orders. The
prices given above are guaranteed only for a period of 1 year following the date of the
release. Prices are subject to change without notice.
In addition, there are seven (7) smaller blocks within the same areas as those flown by magnetic
and gamma ray spectrometry which were covered by electromagnetic (EM) survey. These include
EM1, EM2, EM3, EM4, EM5, EM6 and EM7 covering a total area of 3844 km2 and covered by a
total of 23,806 line kilometers of EM surveys.
ANNEX 3.
----------------------------------------------------------------------------------------------------------------------------, I
agree to the following conditions with respect to use of digital data shown below and acquired
from the Department of Geological Survey and Mines, P.O. Box 9, Entebbe, Uganda:
ii. Data obtained, whether in digital format, by scanning of hardcopy maps or any other
reproduction processes, are licensed for use only for the purpose it was acquired.
iii. Any derivative maps, interpretation and/or reports made from the original data will be only
for internal use of DATA RECEIVER or its affiliates. These second generation products
may not, except as detailed under point iv, be sold, traded, disposed of, transmitted to or
otherwise made available to third parties who have not acquired the original data from
DGSM.
iv. Keep DGSM informed on any reprocessing of digital data and agrees to provide DGSM
with one copy of any reports, maps and enhancements of these data within one year of
completion. Such copies will be for the sole use of DGSM, or de facto staff of DGSM,
and will not be made available to third parties without the written consent of DATA
RECEIVER for a period of two years from the date of receipt of said copies.
vi. Distribution and/or selling of standard or enhanced digital products by DATA RECEIVER
may only be undertaken with the written permission of DGSM.
vii. DGSM retains all copyrights to acquired survey data and maps. Presentation of these
data and maps/images at conferences, websites or in research publications must ensure
that DGSM is credited.
viii. DGSM shall not be liable for any post-processing performed on the DATA RECEIVER.
ix. Failure to adhere to the above conditions may lead to prosecution under international
copyright laws.
