Shape Analysis of Residential Subdivision Parcels of District 1 of Tabriz

Land is of significant importance to human life, whose limitations and the conditions of modern urban life have increased its importance. The main purpose of the present study is the shape analysis of the residential subdivision parcels in the planned texture, worn out texture and informal settlement in terms of length to width ratio using two compactness indexes of Areal form factor and the Hussar Index. The desirability of land subdivision means the proper and optimal use of it in the first place. The research is applied and is descriptive-analytical in terms of method. Uni-variate Wilcoxon, Kruskal-Wallis and Spearman correlation tests were used for analysis. The results of Wilcoxon test for both indices showed that all three textures were in good condition. In addition, the results based on the spatial form factor and Hussar index showed that the planned texture with informal resettlement area and informal settlement area with worn texture was statistically different in terms of desirability of the length to width ratio of parcels. Also, there was no statistically significant difference between the worn-out texture and the planned texture in terms of the length to width ratio in terms of the desirability of residential subdivision parcels. It was then found that the worn-out texture with the average rating of 17458/79 based on the spatial form factor and 17329/15 based on the Hussar index is in the best position compared to the other two textures in terms of optimal ratio of length to width of the residential subdivision parcels. Also the results of both indices have a full correlation and consistency. Therefore, the result is that the spatial form factor and the Hussar index have the same function in the Tabriz region.
