| MOMRA Mapping Reference Framework |
| |
Prior to any surveying and mapping, it is first necessary to
establish frameworks of horizontal and vertical controls. A
reference system is the set of
numeric quantities that serves as a common basis. Therefore, the
Ministry of Municipal and Rural Affairs (MOMRA) has awarded this
project to GeoTech in order to get a very precise
Geographical/Land Information System (GIS/LIS) framework
established by using advanced Global Positioning System (GPS)
techniques.
Today, the GIS/LIS framework is considered as the main frame for
geographic data in Saudi Arabia. It will form the foundation for
all types of Geographic/Land Information System (GIS/LIS)
activities, further breakdown, i.e. densification, for large
scale mapping and many other purposes. This network will satisfy
both government and private sector needs. In addition, such a
unique, precise, and accessible national geodetic control system
will prevent wasteful duplication of control establishments.
The major objectives of the project are as follows:
- Changing Ain Al-Abd geodetic datum to the ITRF-2000 (to be called
MOMRA-2000/MTRF-2000 Datum), which is the internationally used
datum. Thus, it will be possible to directly use the globally
produced surveys and data compiled within this global datum.
- Establishment of MOMRA Mapping Reference Framework that consists of
- 13 stations, one station in each of 13 regions will be used as Internet-based Continuously Operating Reference Stations (CORS)
- Over 600 GIS/LIS stations located all over the Kingdom.
- To
determine transformation parameters between the existing
National Geodetic Network (NGN) datum (based on Ain Al-Abd) and
MTRF-2000.
- To integrate geodetic networks established to date for large scale mapping.
