2. Answer the following questions in about 30 words:

(I) What is map generalisation ?

Ans: Map generalization is the art of simplifying geographical details on a map, like removing small features or merging close ones, to make it clear and readable at its specific scale. It ensures you see the big picture without getting lost in clutter.

(II) Why is map design important ?

Ans: Map design matters because it unlocks information, making features clear, distances accurate, and the whole experience engaging. Like a good story, it guides you through the map's message.

(II) What are different types of small-scale maps ?

Ans: Small-scale maps come in two main flavors:

1. Wall Maps: Think big and bold! These giants grace classroom walls and conference rooms, offering a broad overview of countries, continents, or even the whole world. They're not as detailed as their larger-scale cousins, but they're perfect for getting a quick grasp of the lay of the land.

2. Atlas Maps: These pocket-sized powerhouses are collections of small-scale maps bound together in a book. Think of them as mini-libraries of geographical knowledge, covering the world or specific regions. They're not meant for pinpointing details, but they're fantastic for general reference and understanding big-picture stuff like where countries are, how continents are arranged, or even global patterns like climate zones.

    Both wall and atlas maps, despite their lack of super-zoom detail, are super tools for exploring the world. So, the next time you need to get a sense of a big place, grab one of these little guys and let it be your guide!

(III) List out two major types of large-scale maps ?

Ans: Two major types of large-scale maps, each serving a distinct purpose:

1. Cadastral Maps: Think property lines and ownership details! These detailed maps, typically with scales of 1:1000 to 1:10,000, are all about land. They precisely show boundaries, buildings, and other features crucial for legal and administrative purposes.

2. Topographical Maps: Get ready to conquer mountains and valleys! These maps, usually with scales like 1:25,000 to 1:50,000, focus on the physical landscape. They showcase elevation, terrain, vegetation, and even man-made features like roads and trails, making them perfect for hikers, planners, and anyone who wants to understand the lay of the land in detail.

    Both types of large-scale maps offer a wealth of information, zooming in on specific areas for meticulous planning or exploration. Remember, the next time you need to navigate property boundaries or conquer a mountain trail, these detailed maps are your trusty companions!

(IV) How is a map different from a sketch ?

Ans: Maps accurately represent real-world spaces with scale and detailed information, while sketches offer rough visual depictions, often lacking scale and precision. Think of maps as blueprints, meticulously capturing reality, while sketches are like quick doodles, conveying general ideas.

3. Write an explanatory account of types of maps.
