1.GENERALINFORMATIONPresently the Congolese road network consists of 145,000km of rural road and 7,400km urban mainly built during the period 1920-1960 . The construction was carried out by section, starting from the waterways, railway lines, to connect the hinterland regions which progressively manifested on the economic plan. that from 1950 especially of 1960 that could be taken in the necessity to design coordinated great roads the whole territory National Congolese departmental fixed definitively the content of this knowledge: National Roads (RN) of Regional Routes Priorities (RR1) of Secondary Regional Roads (RR2) network, that is to say + 87.000Km, constitutes the Roads Of Local Interest note that of all this road network, only 5% are paved. The Democratic of Congo still holds the low density of routes in Central Africa with the rate 12,79 Km on 10,000 Km2, 95% of Congolese are still in the without adequate access to adequate transportation networks. The state of the road network does not allow the development of the country or the evacuation of agricultural production from the rural centre to the consumption centres. It also does not allow the Democratic Republic of Congo to play its role as a key transit link to other countries.

1.1 Purpose and Scope of the Document

This document “Terms of Reference” – TOR, is a part of the procedure for the award of The proposed Infrastructure Development Programme of the Democratic republic of Congo – The Execution of LiDAR Surveys for Feasibility and Design Purposes

The purpose of this document is to provide detailed information on the subject of procurement, requirements and specifications.

Annex 1: Product specification and Standard for production of LiDAR and Photogrammetry data for ________________ is a part of Terms of Reference - TOR (this document):

1.2 Project area description

The Democratic Republic of the Congo French: République démocratique du Congo, also known as DR Congo, the DRC, Congo-Kinshasa, or simply the Congo, is a country located in Central Africa. It is sometimes anachronistically referred to by its former name of Zaire, which was its official name between 1971 and 1997. It is, by area, the largest country in Sub-Saharan Africa, the second-largest in all of Africa (after Algeria), and the 11th-largest in the world. With a population of over 78 million, the Democratic Republic of the Congo is the most populated officially Francophone country, the fourth-most-populated country in Africa

The project area of interest’s (AoI’s) to be covered with LiDAR scanning is further described in Chapter 3.

1.3 Spatial reference system

Geodetic Datum

Brief Description: WGS 84 is an Earth-centred, Earth-fixed terrestrial reference system and geodetic datum. WGS 84 is based on a consistent set of constants and model parameters that describe the Earth's size, shape, and gravity and geomagnetic fields. WGS 84 is the standard U.S. Department of Defence definition of a global reference system for geospatial information and is the reference system for the Global Positioning System (GPS). It is compatible with the International Terrestrial Reference System (ITRS). Responsible Organization: National Geospatial-Intelligence Agency Abbreviated Frame Name: WGS 84 Associated TRS: WGS 84 Coverage of Frame: Global Type of Frame: 3-Dimensional Last Version: WGS 84 (G1674) Reference Epoch: 2005.0



Definition of Frame

• Origin: Earth’s centre of mass being defined for the whole Earth including oceans and atmosphere

• Axes: o Z-Axis = The direction of the IERS Reference Pole (IRP). This direction corresponds to the direction of the BIH Conventional Terrestrial Pole (CTP) (epoch 1984.0) with an uncertainty of 0.005″

o X-Axis = Intersection of the IERS Reference Meridian (IRM) and the plane passing through the origin and normal to the Z-axis. The IRM is coincident with the BIH Zero Meridian (epoch 1984.0) with an uncertainty of 0.005″

o Y-Axis = Completes a right-handed, Earth-Centered Earth-Fixed (ECEF) orthogonal coordinate system

• Scale: Its scale is that of the local Earth frame, in the meaning of a relativistic theory of gravitation. Aligns with ITRS

• Orientation: Given by the Bureau International de l’Heure (BIH) orientation of 1984.0

• Time Evolution: Its time evolution in orientation will create no residual global rotation with regards to the crust

Coordinate System: Cartesian Coordinates (X, Y, Z). WGS 84 (G1674) follows the criteria outlined in the International Earth Rotation Service (IERS) Technical Note 21. The WGS 84 Coordinate System origin also serves as the geometric center of the WGS 84 Ellipsoid and the Z axis serves as the rotational axis of this ellipsoid of revolution. WGS 84 geodetic coordinates are generated by using its reference ellipsoid. Defining Parameters: WGS 84 identifies four defining parameters. These are the semi-major axis of the WGS 84 ellipsoid, the flattening factor of the Earth, the nominal mean angular velocity of the Earth, and the geocentric gravitational constant as specified below. Parameter Notation Value Semi-major Axis a 6378137.0 meters Flattening Factor of the Earth 1/f 298.257223563

Horizontal reference system

Brief Description: Universal Transverse Mercator (UTM) system is a specialized application of the Transverse Mercator projection. The globe is divided into 60 north and south zones, each spanning 6° of longitude. Each zone has its own central meridian. Zones 1N and 1S start at -180° W. The limits of each zone are 84° N and 80° S, with the division between north and south zones occurring at the equator. The polar regions use



the Universal Polar Stereographic coordinate system. The origin for each zone is its central meridian and the equator. To eliminate negative coordinates, the coordinate system alters the coordinate values at the origin. The value given to the central meridian is the false easting, and the value assigned to the equator is the false northing. A false easting of 500,000 meters is applied. A north zone has a false northing of zero, while a south zone has a false northing of 10,000,000 meters. Projection method: Cylindrical projection. See the Transverse Mercator projection for the methodology. Lines of contact: Two lines parallel to and approximately 180 km to each side of the central meridian of the UTM zone. Linear graticules: The central meridian and the equator. Properties:

• Shape: Conformal. Accurate representation of small shapes. Minimal distortion of

larger shapes within the zone.

• Area: Minimal distortion within each UTM zone.

• Direction: Local angles are true.

• Distance: Scale is constant along the central meridian but at a scale factor of

0.9996 to reduce lateral distortion within each zone. With this scale factor, lines

lying 180 km east and west of and parallel to the central meridian have a scale

factor of one.

Limitations: Designed for a scale error not exceeding 0.1 percent within each zone. Error

and distortion increase for regions that span more than one UTM zone. UTM is not

designed for areas that span more than a few zones.

Data on a spheroid or an ellipsoid cannot be projected beyond 90° from the central

meridian. In fact, the extent on a spheroid or ellipsoid should be limited to 15–20° on

both sides of the central meridian. Beyond that range, data projected to the Transverse

Mercator projection may not project back to the same position. Data on a sphere does

not have these limitations.

Vertical reference system

The vertical reference system is a one-dimensional coordinate system, in which the reference surface is defined, in terms of which the heights of the points are expressed.

The position of points in the vertical reference system is expressed by ellipsoid and physically defined heights.

The reference surface for defining the ellipsoid heights is the level of the ellipsoid of the WGS84 reference system and the reference surfaces for defining the physical heights are the quasigeoid and geoid.



1.4 The role and responsibilities of PROME

PROME is a legally binding party and in this capacity:

• Administer and supervise the project on behalf of the Government of the Democratic Republic of Congo

• Organize procurement and selection of the contractor in close cooperation • Provide technical and professional assistance, especially with quality control of
