List out two major types of large-scale maps?
The two major types of large-scale maps are Cadastral maps and Topographical maps.
Cadastral maps are drawn to show the ownership of landed property by demarcating field boundaries of agricultural land and the plan of individual houses in urban areas. These maps are prepared by government agencies to realise revenue and taxes and are drawn on a very large scale, such as 1:4,000.
Topographical maps are prepared based on precise surveys to show topographic details such as relief, drainage, agricultural land, forest, and settlements. These maps are prepared as a series by national mapping agencies like the Survey of India at scales like 1:50,000 or 1:25,000.
Explanation
According to the textbook context provided under the section 'Types of Maps Based on Scale', large-scale maps are explicitly divided into two types: (a) Cadastral maps and (b) Topographical maps. The context defines Cadastral maps as those showing ownership and boundaries for revenue purposes, and Topographical maps as those based on precise surveys showing detailed physical features.
Solution Steps
Step 1: Identify the classification of large-scale maps from the text, which lists Cadastral maps and Topographical maps.
Step 2: Define Cadastral maps using the provided context (ownership, revenue, large scale).
Step 3: Define Topographical maps using the provided context (precise surveys, topographic details, specific scales).
