ing system. Eventually these data will be inserted into the carto-
graphic database and used for producing cadastral maps.
Quality Control
Field verification and visual editing procedures are used to assess
the esthetic quality, adherence to cartographic specifications and
completeness of content of plotted overlays before shipment to
Cairo for translation to ARC/Info format. Spatial topology is
verified and maintained through the use of ARC/Info’s built in
utilities for cleaning the topology of graphic files after translation.
Specialized proof plots with temporary symbols which will be
used to verify database attributes and spatial integrity.
Configuration
The Cadastral Overlay Production Module consists of the
following systems.
e Data Collection System — This system controls the collection
of parcel, administrative and political boundary features as well
as the supplemental topographic and cultural features needed
for the production of cadastral maps. The primary data collec-
tion instrument is the SOKKIA Set 3 Total Station equipped with
magnetic data collectors. Thirty three of these instruments
have been acquired for the project’s use.
* Data Processing System — This system controls the editing
and plotting of the data collected with the Total Stations. It
consists of networked printers, plotters and IBM-compatible
computers equipped with graphic accelerators and capable of
running AutoCAD software. The network is managed with
Novell's NetWare.
Cadastral Map Publishing System
The unavailability ofthe Map Production Module at the start of the
project necessitated the development of a complete, but tempo-
rary, Cadastral Map Publishing System ineach governorate cadastral
field office. This system permits the preparation of:
* Cameraready film positives of 1:2,500 scale cadastral maps.
* Camera ready film positives of 1:1,000 plats of built-up
areas.
It consists of additional printers, plotters and IBM-compatible
computers equipped with graphic accelerators and running
AutoCAD software. Cadastral map production is accomplished
with AutoCAD. Arabic calligraphy is placed on the maps with X-
fonts software.
System Administration
Administration of this module is also the responsibility ofthe ASD
Systems Manager. He establishes backup schedules for gover-
norate cadastral offices and oversees weekly off-site archiving of
all collected cadastral data. Under his direction, the Systems
Support and Development Department is responsible for hard-
ware maintenance at outlying cadastral offices and the operation
and maintenance of their Novell networks. Software develop-
ment, currently the job of the Geonex Cadastral Data Processing
Advisors, will in time be shifted to ASD's Systems Support and
Development Department.
Final Products
This module produces:
* Digital files containing the parcel, administrative and politi-
cal boundary data which when overlaid on selected planimetric
features enable the publication of 1:2,500 scale cadastral maps.
The supplemental planimetric data required for the production
of1:1,000 scale cadastral plats of builtup areas are also included.

Eventually, camera ready film positives of 1:2,500 scale cadastral
maps and 1:1,000 scale plats of built up areas will be produced in
the map publishing system ofthe Map Production Module. In the
interim, they are being produced with the cadastral map publish-
ing system.
LAND RECORDS PRODUCTION MODULE
Data Sources
The primary sources of the information needed to populate the
land records database are contracts of sale and existing tax and
cadastral records. New data collection forms, LRMS DC Forms,
have been designed for this task. When completed by ESA’s data
collection and scrubbing teams, the information contained on the
forms is keyed into formatted Paradox screens corresponding to
the LRMS DC Forms.
Land Records Database
Data items needed for the production of the Siguel El Aine and
related reports and forms are contained in the LRMS database.
These data are compiled, stored and managed by Paradox which
has been front-ended by Sharouk, a locally produced Arabization
utility, to allow users of the Land Records Production Module to
work in Arabic. Current LRMS data items are listed in Figure 2
which shows the system table to which each data item has been
assigned.
Quality Control
LRMS data entry forms are visually checked against the data
collection forms before being entered into the database. Data
items requiring standardization such as governorate, district and
village names, nationality, and religion are controlled by internal
tables accessed by a series of data codes. After keying, data
entered into the database are printed out and independently
checked against the data entry forms. Needed corrections are
made using the appropriate data entry screen.
Database integrity is verified at each stage by the database
management team. Once the data are accepted as correct, the
integrity ofthe database becomes the responsibility of the LRMS
database administrator.
Configuration
This module consists of three systems.
e Data Collection and Standardization System — This system
controls the collection of the data items needed to populate the
land records database. It is a manual system. Data collection
currently requires from 45 to 60 minutes per record.
e Data Entry and Verification System — This system controls
the population of the land records database. It consists of
networked printers, IBM-compatible PCsrunning Paradox and
a file server. The network is managed with Novell's NetWare.
e Report and Form Production System —'This system controls
the production of reports and forms as well as ad hoc queries of
the database. It consists of networked printers and IBM-com-
patible computers running Paradox.
System Administration
Administration of the Land Records Production Module is the
responsibility ofthe ESA Land Records Manager. She establishes
backup schedules, oversees weekly off-site archiving of the land
records database, and controls access to the database. She is also
responsible for maintaining the integrity of the LRMS database,
