Multifractal analysis has been a useful tool in describing the spatial heterogeneity of urban forms. However, how to define the “form” and choose the right data source to study urban form in the multifractal analysis is still to be solved. This paper is aimed to make a comparison of three types of urban maps from the perspective of the multifractal parameters. The three types of data sources are the map of centroids of buildings (MCB), the map of buildings (MB) and the map of artificially used lands (MAUL). Based on the multifractal theory, we utilize multifractal measurement of 10 major cities in the world to make empirical comparisons from the perspective of multifractality analysis and robustness analysis. The case studies have drawn the following conclusions. First, from the perspective of multifractality analysis, the most advisable data in the study of urban form is the map of centroids of buildings (MCB). Second, the map of buildings (MB) performs as an intermediate transition from the map of centroids of buildings (MCB) to the map of artificially used lands (MAUL). Third, the results of multifractal parameters based on the artificially used lands (MAUL) are the least satisfactory.
