GIS Database for the EPSMO Project 2
1. INTRODUCTION
This document presents the development of the Geographic Information
System (GIS) database within the EPSMO Project. The objective of the
development of the GIS database was to create an array of thematic layers
(biophysical and socio-economic), covering the geographic area of the
Okavango River Basin, with the intent to support: the assessment and strategic
decision-making by partners in the EPSMO project; the existing management
structures within the riparian countries of Angola, Botswana and Namibia; and,
to a certain extent, the awareness of general public.
More specifically, the GIS database is indented to aid with:
· Meeting many of the information needs of the Project, especially in
regard to the technical Environmental Flows Assessment reporting;
· Facilitating policy-making in the riparian countries, concerning water
management and environmental needs;
· Characterization of the river basin to support the transboundary
Diagnostic Analysis;
· Water quality issues, based on surface water quality monitoring data
when available;
· Cooperation on transboundary conservation areas and wildlife
information integration;
· Consider potential future hydro morphological alterations: dams,
hydropower plants, agriculture infrastructures, etc.
The GIS database, is in part comprised of the "top-down" ready GIS layers that
are available from various sources and/or in the public domain and chosen on
the basis of information prioritized by the Project partners. Nevertheless, in view
of different stages on availability/existence of geographic information data in the
basin countries (Angola, Namibia, Botswana and Zimbabwe), a considerable
range of the so called "bottom-up" layers, had to be produced and incorporated
in the database to harmonize and provide better detailed GIS data for the
project tasks and goals and as wel to the related partner institutions.
The content and quality of this multi-thematic GIS database is oriented towards
a strategic-level, transboundary assessment, decision-making and awareness
concerned with hydrologic variables and environmental and socio-economic
parameters of the Okavango River Basin, organized in a set of different
thematic groups that define the extent and relevance of the database.
GIS Database for the EPSMO Project 3
2. METHODOLOGY
2.1 INTRODUCTION
The development of the GIS database for the EPSMO project is outlined below.
The extent of contents and data production of the database must take in
consideration the fact that the Project was conducted in a short-period of time (8
months), with restricted possibilities to develop the database extensively.
2.2 MAIN STEPS
2.2.1. Needs and Requirements
The EPSMO GIS database, ultimately presents a toll to serve several purposes
for different target groups and goals, such as government agencies responsible
for the management of water resources, local/regional state administrations
dealing with water issues, river basin commissions and other stakeholders,
such as other national and local institutions, researchers and the public in
general.
Nevertheless, in a first stage, the choices for the content of the database, are
based fundamentally on the project data priorities, which were communicated
principally at the meeting of the EPSMO in Maun in October 2008. Based on the
needs and requirements presented, the following "top-down" assembly of data
layers were prioritised for the database concerning the all of the Okavango
Basin:
· International borders and administrative units;
· Hydrological
data;
· Climatologic
data;
· Geological, geomorphologic and soil data;
· Land use / land cover;
· Population
distribution;
· Digital elevation model.
"Bottom-up" layers that were also prioritized to be included, when available, in
the GIS database:
· Hydrographic network and units;
· Hydrologic
monitoring
stations;
· Water quality monitoring data;
· Wildlife
distribution;
· Protected
areas;
· Infrastructures
network.
2.2.2. Inventory of Data Sources and Acquisition of Data Sets
In order to fulfill the priorities established, it was necessary to start an inventory
of potential data sources. For that, factors that are relevant for the search and
acquisition of pre-existing GIS data, include aspects such as the data quality,
availability, cost and users rights. In this initial step, the inventory of data should
be considered at the 4 national levels involved independently, and guided by
the proposed structure presented in part
GIS Database for the EPSMO Project 4
4. Fol owing the acquisition of the data sets identified by the inventory, this
information was processed and analyzed.
2.2.3 Data Harmonization
Data harmonization can relate to different types (see table 1), and is here
referenced as the process by which data sets with dissimilar characteristics
(geodetic, temporal, thematic) are modified in order to contain the same
reference parameters so that can be properly analyzed and used. This process
can be rather time consuming, depending on the type of harmonization
required. Concerning the geodetic reference system for the GIS database, the
procedure was carried out using the ArcGIS 9 software (ArcTools/ArcCatalog),
in order to project or reproject acquired data to the database projection
coordinate system. Another factor, is if a specific data source covers a larger
area then the EPSMO target area (the Okavango River Basin). For this mater, it
is necessary to clip according to the defined database boundaries. Raster files
were resampled during the projection process using the "nearest neighbor"
resample method for land cover data, or a "bilinear" resample method for
elevation data and remote sense data.
Table 1 Types of Data Harmonization
Harmonization Type
Description
Intralayer harmonization
Harmonization of data within a single data
layer
Interlayer harmonization
Harmonization of data between data layers
Geodetic harmonization
Intra or interlayer harmonization with respect to
the geodetic reference system. The adopted
reference system and projection should be
applied to the data
Temporal harmonization
Intra or interlayer harmonization with respect to
the temporal dimension of the data. Optimally,
to be fully comparable, all data layers should
originate from the same point in time
Thematic harmonization
Intra or interlayer harmonization with respect to
the thematic content. Optimally all data layer of
a specific thematic variable should have the
same attributes, be measured in the same way
with the same measurement interval and with
the same constrains.
In the case of the GIS database of the EPSMO project, the target area
comprises a Transboundary reality, which implies data originating from 4
different countries, with varying thematic, geodetic, temporal and geographic
contents. It is to be understood that same of the existing thematic layers
available do not cover with the same level of spatial detail or attributes included,
for the areas of the Basin shared by the 4 countries, presenting a challenge
when the generalization is not the option, and in many cases addressing
fundamental information gaps. Temporal harmonization can be partly achieved,
in what concerns themes like landcover, infrastructures, population, etc, if the
available sources options are limited to the most recent ones, centering around
the time frame between 2002 and the present. A more complex task can be the
thematic harmonization of layers, especially when "bottom-up" data layers are
later added to the database. This might imply the need to access the specific
national and international coding systems and parameters involved in the
production of the original data, invariably reflecting different approaches and
instruments used.

2.2.4 Database Structure
The GIS information assembled, is presented under an organized thematic data
structure as depicted below. The subdivision indicated does not reflect the
availability of layer sets for all the different sub aggregations. In stead, serves
has a proposed hierarchical guidance for the future expansion and inclusion of
information sets in a update and shared dynamic multi-thematic database
process.

2.2.5 Database Information
The EPSMO GIS database has a easily accessible metadata for the
identification and further use of the data for various applications areas. Each
layer is associated to a metadata file with a description created using the
standards established by the Federal Geographic Data Committee of the US
(FGDC-ESRI), included in the ArcCatalog metadata tools.

3 DATABASE DESCRIPTION: GENERAL CONSIDERATIONS
3.1. OVERALL CHARACTERISTICS
The multi-thematic GIS database covering the transboundary Okavango River
Basin, is composed to a large extent by a collection of harmonized data layers
acquired from a wide variety of sources. For this reason, it is a database with a
pronounced variable interlayer characteristics and qualities, and, at the same
time, developed to assist the project priorities and goals.
3.2. COORDINATE SYSTEM, PROJECTION AND GEODETIC INFORMATION
The geographic and cartographic data produced in the region until recently is
based fundamentally in regional coordinate systems, not allowing immediate
integration and comparison of this cartographic sets. The 4 national coordinate
systems are the following:
· Angola Transverse Mercator (Projection), Camacupa (Datum);
· Botswana Transverse Mercator (Projection), South African (Datum);
· Namibia Transverse Mercator (Projection), Schwarzeck (Datum).
· Zimbabwe Transverse Mercator (Projection), Clark 1880 (Spheroid).
The EPSMO GIS database is referenced in the World Geodetic System 1984
(WGS 1984) geographic coordinate system (GCS). The parameters and
geodetic model are:
Geographic Coordinate System
GCS Name: WGS (1984)
Latitude of Reference: 0.0º
Longitude of Reference: 0.0º
Geographic Coordinate Units: Decimal degrees
Geodetic Model
Datum: WGS 84
Ellipsoide: WGS 84
Semi-major Axis: 6378137
Inverse Flattening: 298.257
3.3. SCALE
The importance of spatial scale in geographic related assessments, and the
effect scale has on the interpretation and representation of spatial phenomena
being observed or modeled is a key factor in the overall consistency of the
geographic information systems outputs and validity. Multiple scales may be
necessary for interpreting and characterize a complete system over time and
space. Nevertheless, in a GIS database layers can be zoomed in or out, so it is
extremely important to maintain data of similar scale grouped apart from data or
lesser or greater scale, in order to prevent erroneous overlay and analysis of
data of non-common scale.
Taking in consideration the size and heterogeneity of the are considered as the
Okavango River Mega Basin (Fig. 1), it was necessary to subdivide the GIS
data information in different scale groups, prioritizing the more detailed data
sets to the Okavango Active Catchment Area and Delta Sector (Fig. 2)
GIS Database for the EPSMO Project 8

Figure 2 Okavango Active Catchment Area (in blue).
The EPSMO GIS database aggregates data in two separate spatial scale
groups (see Part I and II of the report), with the scale range for each category
as follow:
Okavango Macro Basin >1:500 000 <1: 10 000 000
Okavango Active Catchment Area >1:200 000 <1:500 000

3.4 GEOGRAPHIC COVERAGE
The bounding coordinates (in decimal degrees) for the EPSMO GIS database
are as follows:
North Bounding Coordinate: -12.00
West Bounding Coordinate: 16.00
South Bounding Coordinate: -22.00
East Bounding Coordinate: 24.00
The set of bounding coordinates serves only as an overall reference to
determine the geographic layout enclosing the Okavango Mega River Basin, the
focal area of the project.

provinces;
Namibia: part of the Kavango, Ohangwena, Otjozondjupa and Omaheke
regions;
Botswana: part of Ngamiland, Chobe, Central, Francistown, Western and
Gaborone districts.
Zimbabwe: part of Matabeleland North and Matabeleland South provinces.

4 DATABASE DESCRIPTION: SOURCES
4.1. DATA SOURCES
As referred earlier, there is a heterogenic reality concerning GIS data for the
Okavango River Mega Basin, since the production of this resources has been
undertaken in different conditions and approaches in the four riparian countries
independently: Angola, Botswana, Namibia and Zimbabwe. Under this
consideration, it is presented in the next sections sources in each country that
al ocate viable GIS data.
4.1.1. Angola
Instituto de Geodesia e Cartografia de Angola (IGCA), Luanda
This institution is the national repository and producer of cartographic data,
namely topographic maps. Presently IGCA provides topo maps in analogue
(paper) format for the all country in the scales: 1/1 000 000; 1/500 000; 1/250
000 and 1/100 000. Incomplete collections cover selected parts of the country at
1/50 000 and 1/25 000. There is an ongoing process of digitizing the map and
aerial photo collections in to digital formats. All of the above map scale sets
have already bean scanned, and some vectorization has been conducted.
FAO, Luanda
This organization has been engaged in the compilation of GIS data for Angola
for a large variety of projects, namely the production of the "Angola Municipality
Atlas", were general data related to agriculture, livestock, household food
security and more is provided. In this product, FAO provides also a complete
col ection of 1/100 000 georeferenced topographic maps for the all country.
Instituto para o Desenvolvimento Florestal (IDF), Luanda
IDF contracted Angola Alliance, a South Africa company consortium, to conduct
a land cover analysis (including change over time) for the country, which wil
form the basis of IDF's forest inventory. This data is so far not available for the
general public.
Sinfic, Luanda
This private company has been assembling GIS data for Angola, and has the
potential of providing thematic layers for the EPSMO project, namely vector
layers extracted from the 1/100 000 topographic maps. Administrative
boundaries of Angola have been assemble for the project.
4.1.2. Botswana
Department of Survey and Lands, Gaborone/Maun
This institution is the national repository and producer of cartographic data,
namely topographic maps. The country has incomplete coverage of topographic
maps in the scale 1/50 000 and complete, although outdated, in the scales
1/250 000 and 1/500 000. The cartographic quality of the topographic series
that cover the North of the country is generally poor.
GIS Database for the EPSMO Project 11
Harry Oppenheimer Okavango Research Centre (HOORC), Maun
HOORC is a research center of the University of Botswana, that has been
engaged in promoting and extending the use of GIS components in the
institution scientific activities, and has so far assembled a comprehensive data
bank of GIS data for most of the North of Botswana. It is a key partner of the
EPSMO project.
4.1.3. Namibia
The Surveyor General, Windhoek
This institution is the national repository and producer of cartographic data,
namely topographic maps. The country is covered at the scales: 1/50 000;
1/250 000; 1/500 000, in analogue and digital formats. There is a complete
col ection for the country of aerial photos for the years 1996 and 2006, available
in digital format. The institution has a GIS department that has al the thematic
layers that are used in the production of the most recent topographic maps
series (NE of the Country), in vector format.
Ministry of Environment and Turism (MET), Windhoek
The institution with the responsibility of promoting and protect the natural
resources of Namibia, namely the protected areas network, has a considerable
databank on wildlife census data formatted in GIS language.
Lux-Development, Rundo
This institution has been conducting development cooperation programmes in
NE Namibia as the implementing agency for the Government of Luxembourg. In
the Kavango and Caprivi regions, it's been the key player in developing a GIS
database and cartographic production for this part of the country, with a vast
assembly of geographic referenced data, under the aim of produce an updated
version of the 1/50 000 topographic maps of Kavango and Caprivi, and to
create and develop awareness of using GIS data (cartographic data in digital
format) for regional development.
Research and Information Services of Namibia (RAISON), Windhoek
This private company, has been engaged in the fields of environmental
information, education and health for the Okavango River Basin, and has
compiled a GIS database for this purposes.
4.1.4. Zimbabwe
The Surveyor General, Harare
This institution is the national repository and producer of cartographic data,
namely topographic maps. A collection of 1/250 000 maps has been included in
the database.
GIS Database for the EPSMO Project 12
4.1.5. Other Sources
Russian Topographic Map Series
The quality and extent of the former Soviet Union cartographic efforts, have until
recently been unknowned of the general public. Most of Southern Africa has
been mapped at detailed scales of 1/100 000 and 1/200 000 during the mid
80´s to the late 90´s by Russian cartographers. This information is now
available, in most part, with limited acquisition constrains, which make this data
ready to use if necessary, by the absence of more qualified topographic
information for some of the areas of the sub continent.
The Soil Maps of Africa
A large raster, non georeferenced, data bank of thematic maps mainly related
with pedology, for the African continent. This information is provided by the Joint
Researched Center of the European Commission, and is freely available from
http://eusoils.jrc.it/ESDB_Archive/EuDASM/Africa/.
Soil/Terrain (SOTER) Database for Southern Africa
A soil GIS database is available, by the agreement between FAO and ISRIC for
the compilation and harmonization of SOTER databases, for seven countries
(Angola, Botswana, Namibia, Mozambique, South Africa, Swaziland, Tanzania
and Zimbabwe) at an equivalent scale of 1/2 000 000.
Landsat GeoCover 2000/ETM+
The Landsat satellite series represents one of the longest continuous records in
remote sense observation of the Earth, at a nominal scale ranging from 1/250
000 to 1/100 000. Only recently, mid 2003, the latest sensor in the series
(Landsat 7 ETM+) developed a malfunction that has prevented since then the
proper acquisition of information from this sensor. The data is distributed for
selected dates freely from the Global Land Cover Facility. Sets of the complete
collection for this satellites data can be purchased from the US Geological
Survey.
Shuttle Radar Topography Mission (SRTM) 90m Digital Elevation Data
In February 2000, with the aid of a 60-m (200-ft) boom added to the SIR-C, the
Shuttle Radar Topography Mission (SRTM) circled Earth for 10 days mapping
80 percent of the world's land area. The resulting high-resolution topographic
map is the most accurate available and provides a worldwide topographic data
set between 60° N and S latitudes with a consistent datum. This provides the
fundamental base information in the characterization of the topography
elevation, slopes, aspect, etc., and underlines the essential level for building
analytic models. At the time this data is provided freely, by the CGIAR
Consortium for Spatial Information, at a resolution of 3 arc seconds (aprox.
90m), for the region concerned.

The Okavango River Basin Transboundary Diagnostic Analysis Technical Reports
In 1994, the three riparian countries of the Okavango River Basin Angola, Botswana and Namibia agreed to plan
for collaborative management of the natural resources of the Okavango, forming the Permanent Okavango River
Basin Water Commission (OKACOM). In 2003, with funding from the Global Environment Facility, OKACOM
launched the Environmental Protection and Sustainable Management of the Okavango River Basin (EPSMO) Project
to coordinate development and to anticipate and address threats to the river and the associated communities and
environment. Implemented by the United Nations Development Program and executed by the United Nations Food
and Agriculture Organization, the project produced the Transboundary Diagnostic Analysis to establish a base of
available scientific evidence to guide future decision making. The study, created from inputs from multi-disciplinary
teams in each country, with specialists in hydrology, hydraulics, channel form, water quality, vegetation, aquatic
invertebrates, fish, birds, river-dependent terrestrial wildlife, resource economics and socio-cultural issues, was
coordinated and managed by a group of specialists from the southern African region in 2008 and 2009.
The following specialist technical reports were produced as part of this process and form substantive background
content for the Okavango River Basin Transboundary Diagnostic Analysis
