Objective
Analyze the relief diversity in the study area using the ArcGIS softwareand patch analyst extension
Produce a final output map presents the degree of the relief intensity in area which covering a part of Saxon Switzerland, using ARCMAP. DEM’s and layer files will be included to produce several maps, all data gathered will be organized and compiled in a database

The Study Area
Analysis Of Relief Diversity. The Example of Saxon Switzerland National Park Hiba Idris 10.04.23
• The area of interest for this study is a part of Saxon Switzerland National Park Region “Sächsische Schweiz” which is exemplified by the national park region Saxon Switzerland (398 km²), and consists of a national park (93.5 km²) and a surrounding landscape conservation area (287.5 km²)
• The selected study area has a total area of (81.36 km²)
• The topography of the area is characterized by its sandstone rocks “Elbe Sandstone Mountains”, The Elbe River breaks through the mountain range in a steep and narrow valley; therefore, the region involves a complex distribution of rocky mountains, plains, hills, valleys and Elbe valley
• The Saxon Switzerland is an intensively fissured and rocky canyon landscape. The highest peak of the National Park is at 556 meters above sea level but only in short distance to the valley of the Elbe river at 110 to 120 m (Wächter and Boehnert 1998)

![Page 9: Hiba idris - GIS Based Visualisation of the Aesthetic Value of The Landscapes. The Example of Saxon Switzerland](https://reader038.vdocuments.net/reader038/viewer/2022102804/548b492bb47959a93b8b4a33/html5/thumbnails/9.jpg)
What is Patch Analyst for ArcGIS
Tool for quantifying landscape structure
Extension to the ArcGIS® software system that facilitates the spatial analysis of landscape patches and the modeling of attributes associated with patches
Used for spatial pattern analysis
Includes capabilities to characterize patch pattern and the ability to assign patch values based on combinations of patch attributes

What can it be used for ?
Patch Analyst allows the data to be analyzed within three levels of hierarchy:
1. Landscape relates to all the patches, polygons, contiguous cells or shapes in a view or theme
2. Classes relate to all the patches, polygons, contiguous cells or shapes in a theme, view or landscape that have the same value for a given attribute
3. Patches relate to the individual polygons or contiguous set of cells or shapes. Each patch has a separate record or row in the theme attribute table

Why Relief diversity Index
The practical meaning of the landscape evaluation is spatial development used for the for the tourism activities
The relief diversity index used with set indexes which reflects the aesthetical value of the landscape

Shannon's Diversity Index (SDI)
• Used to measure relief intensity in categorical data or the proportional abundance of each patch type within the landscape
• only available at the landscape level and is a relative measure of patch diversity
• The advantage of this index is that it takes into account the number of species and the evenness of the elevation classes

• ni The number of individuals in species i; the abundance of species i.• S The number of species. Also called species richness.• N The total number of all individuals• pi The relative abundance of each species, calculated as the proportion of individuals of a given species to the total number of individuals in the community:

Relief Diversity

The region displays high to very high relief diversity
Low values cover only 5% of the study area (inside the National Park )
High and very high diversity values exclude agricultural and areas and settlements areas
Along the Elbe Valley: high values

Conclusions
![Page 29: Hiba idris - GIS Based Visualisation of the Aesthetic Value of The Landscapes. The Example of Saxon Switzerland](https://reader038.vdocuments.net/reader038/viewer/2022102804/548b492bb47959a93b8b4a33/html5/thumbnails/29.jpg)
Benefits
Allow to analytically derive morph graphic features (such as slope, aspect, curvature, etc.)
Allow to create value-added map products
The assessment of spatial landscape diversity and relief diversity could be easier and faster
A lot of parameters could be carried out
External nets, regions, analyses units could be exported, then joined with patch tools
possibility to derive small units which could match other statistical parameters
The opportunity to explore such possibilities within Patch Analyst was not hard to perform
