Spatial Correction of Cadastral Maps Based on Satellite Imagery

Abstract

It is well known that most of the cadastral maps and property plans in Iraq are preserved in paper form, with the majority dating back to the 1930s. These maps are widely used for various purposes, such as urban planning, sewage networks, and electricity networks. However, most of these maps suffer from some distortion and wear, with some being torn and taped due to the nature of the paper material and its handling, resulting in severe physical distortion. To address these issues, it is necessary to convert these maps into a digital format and perform corrective processing to mitigate the effects of past errors. Scanning alone is insufficient as it introduces many errors. Recently, fast and accurate computer software has become available that can process data from these maps and paper drawings, including addressing the wear they have undergone, and update them to meet the needs of local authorities developing and investing in these maps and implementing development projects. This process is also essential for establishing a digital foundation for the database. Geographic Information System (GIS) applications are widely used to enhance and assist decision-makers in making decisions that align with their purposes and application scenarios.
