Geological Map
The Geological Map paper size, a unique and specialized format, is an integral part of the ISO 216 series. This international standard for paper sizes is widely recognized and utilized across various industries. The Geological Map size specifically caters to the needs of geologists and cartographers who require a larger canvas to accurately depict intricate geological formations.
With dimensions measuring 660mm x 560mm, the Geological Map paper size provides ample space for detailed representation of complex geological data. It allows professionals to capture extensive information on a single sheet, enhancing readability and comprehension. This makes it an invaluable tool in fields such as environmental planning, resource exploration, hazard assessment, and academic research.

Interestingly enough, despite its specific application in geology and cartography, the Geological Map paper size adheres to the same aspect ratio as other ISO 216 series formats. This ratio of 1:√2 ensures that two pages next to each other or one page halved down its longer side will yield two smaller pages with identical proportions. Such consistency facilitates seamless scaling between different sizes within the series.
Moreover, while not part of any ANSI series - which primarily serves North American markets - the Geological Map format's universal appeal lies in its adherence to ISO standards. These standards are globally accepted due to their focus on efficiency and interoperability across different systems.
The Geological Map paper size is more than just a large piece of paper; it's a critical tool that aids in our understanding of Earth's structure and resources. Its standardized dimensions under ISO 216 ensure consistent scaling while providing ample space for detailed geological representations.

Interesting facts about Geological Map
1: Geological Map Paper is Waterproof
Geological map paper is specially designed to be waterproof. This feature allows geologists and cartographers to work in various weather conditions, including rain or high humidity environments, without worrying about the paper getting damaged.
2: It Resists Tearing and Abrasion
Geological map paper is known for its exceptional durability. It is resistant to tearing and abrasion, making it ideal for fieldwork where the maps may be subjected to rough handling or constant folding and unfolding.
3: It Has a High Opacity
The high opacity of geological map paper ensures that information printed on one side does not show through on the other side. This characteristic allows for clear and legible maps, even when printed with vibrant colors or intricate details.
4: It Is Acid-Free
To ensure long-term preservation of geological maps, the paper used is acid-free. Acid-free paper prevents yellowing and deterioration over time, making it suitable for archival purposes.
5: Geological Map Paper Comes in Various Sizes
Geological map paper is available in different sizes to accommodate various mapping needs. Common sizes include A0 (largest), A1, A2, A3, and A4 (smallest). These standardized sizes make it easier to handle and store maps uniformly across different projects.
6: The Origin of Standardized Paper Sizes
The standardized series of paper sizes used globally today originated from a system developed by Dr. Georg Christoph Lichtenberg in the late 18th century. However, it was later refined by German engineer Dr. Walter Porstmann in the early 20th century, leading to the adoption of the DIN (Deutsches Institut für Normung) paper sizes.
7: The A Series Paper Sizes
The A series paper sizes, including those used for geological map paper, follow a simple mathematical formula. Each size is obtained by halving the larger dimension of the previous size. For example, A1 is half the size of A0, and A2 is half the size of A1.
8: The B and C Series Paper Sizes
In addition to the A series, there are also B and C series paper sizes. The B series follows a similar formula as the A series but with slightly different proportions. The C series is primarily used for envelopes and follows yet another set of proportions.
9: Geological Map Paper in North America
In North America, letter-size (8.5 x 11 inches) and legal-size (8.5 x 14 inches) papers are commonly used for geological maps instead of following the international standard sizes. This can sometimes lead to compatibility issues when printing or reproducing maps from different regions.
10: Specialized Printing Techniques for Geological Maps
To enhance readability and durability, geological maps often utilize specialized printing techniques such as lithography or offset printing. These techniques allow for precise reproduction of intricate details while ensuring long-lasting quality on rugged map paper.
