Methodological background of GIS

Combination of digital maps with direct data base access and other types of digital data like aerial photos, satellite images and relational data bases

Suitable for vector as well as raster data

Information is saved in a structure of thematic layers

Compilation of orthophotos,DEM, and other surface data

based on the unique identifier technique for each geographical entity

Challenges for remote sensing in the cadastre process

Satellite images minimizing the age of remote sensing data

Large visible and invisible range of datacollection

High resolution data is available on aerialphotos

Digital production of orthophotos reducesthe survey coast

High accuracy and rapid production timesfacilitate the cadastre process

But there is no replacement of field surveyand dicussion process in the provinces

Land Management with GIS



Situation in Cambodia

Cambodia has difficulties in managing land and othernatural ressources thus achieving economic prosperity for the country as a whole.

Environmental protection and national park management are closely linked to factors of land and land management

GIS and remote sensing applications are already used to improve cadastral systems in theadministration

Proper adaption of Hard- and Software is required

A large scale GIS is already under progress, as well as integrated GIS databases



Conclusion

GIS and remote sensing applications are already in use to improve cadastral systems and guarantee the security of land tenure in Cambodia.

Good and vital co-operation with all users and agencies is highly recommended for the near future.

Modern Land Management and cadastral administration organisms in Cambodia require a large number of well-trained academic applicants

The applications of GIS will help planners and decision makers in land use planning and developing land resources in Cambodia

Therefore staff training and academic education should have the highest priority !
