ABSTRACT
The establishment of a land information system is shown by the project Neustadt. Data
from existing maps and aerial photos are combined interactive graphically.
The task, hardware and software components and organization are described.
1. introduction
Is there a need for an establishment of a land information system?
With growing number of data collection sets in the communities it becomes more and
more important to unite the separate sets. In addition it has been shown as necessary
to have complete and updated information available. A direct access from different
users is economic and is only possible in the case of computerized data base systerns.
The combination of existing data sets as cadastre, utility networks and planning informa-
tion must be done in relation to a geometric unobjectionable system. in our case - photo-
grammetric measurements.
The stablishment of a land information system is tested in the small town Neustadt near
Hannover.
2. Project Neustadt - Task and Existing Information
Neustadt has, besides various types of housing areas also light industry and a small
commercial zone in the centre of the town. The main railroad, the Federal Highway
from Hanover to Bremen and the river Leine is passing the town.
All this is located in an area of 4 km? corresponding to one sheet of the German topo-
graphic map 1:5 000 (DGK 5], the ideal size of a test area.
The federal cadastral office provedes all information concerning land registers, ca-
dastral maps and survey points. Also the local authority and the public utility companies
were willing to give the information about their network data.
The input for the future Land Information System (LIS) in Neustadt are those cadastral
data. which are layed down in maps. legal titles will not be implemented into the system.
The maps are in a scale of 1:1 000.
Other components of the LIS are:
traffic: railways. main roads, streets. pedestrian area, sidewalks, bike roads:
builtup areas: housing. commercial, light industrial and town-planning data:
topography: agricultural land, trees, parks, river banks etc.;
4, utility: water, gaz, electricity, sewerage. telephone.
GO iN) ms
The data of utilities are layed down usually in maps. but in different scales and with
various reference to the survey points and the cadastral maps. Information about traf-
fic and topography. in the way we need it for a LIS, is today not to be found on any map.
The task of the project is to combine all data without contradictions into one system.
