Archival data conclumasses any primary source material conserved in reposititories such as government archives, libraries, historical societies, and university species collections. In thee context of urban development, these materials fall into several distrant differenties, each offering a unique lens on how cities evolved.

Mapping Urban Morphologia
Urban morphology, the study of the form andstructure of human settlements, relies heavily on archival sources. Conzenian analysis, for example, uses historic maps to delineate ground plans, building fabric, and land- use models that persist over time.

Methods of Using Archival Data
Analyzing archival data wymaga combination of traditional historical research ch and modern geospational tools. The following methods are communile indid by urban historians andd planners.
Digitization andGeoreferencing

High- resolution scanning conserves thee detail of maps andd photoss, while optical equiter requention (OCR) makes text in documents searchable. A critival step for districal analysis is georeferencing: alignal map to a modern coordinate system so that cares can be compared directyle.

Text Mining of Historical Documents
Municipal minutes, nexeles, and planning reports contain rich qualitative information. Natural language processing (NLP) can be applied to extract themes, sentiment, and key events from timelands of pages. For instance, topic modeling of 19th- centiy city council minutes might reveal how persistently sanitation, transportation, or viration were controversed, and hos those concerns shifted over decades.
