Today we'll start by talking about the Bureau of Indian Standards, or BIS. It's essential because it helps us maintain a certain quality in map making. Who can tell me what kind of norms BIS might set for maps?
Maybe it sets rules about how big the map should be?
Great point! BIS does set norms about map layout, scale, and even symbology. Remember, we refer to this as the 'LSS' of mapping—Layout, Scale, and Symbology. Let's dive deeper into how these norms affect the usability of maps.
So are these standards important for understanding maps?
Absolutely! Consistent standards make it easier for users to read and interpret maps without confusion. It’s like sharing a language; if everyone understands the symbols, communication becomes clear.
Metadata Standards (ISO 19115, FGDC)

Now, let’s focus on metadata standards like ISO 19115. What do you think metadata means in the context of mapping?
Isn't it like extra information about the map's data?
Exactly! Metadata provides details like the source of the data and its accuracy. ISO 19115 ensures that descriptive information is available, making data easier to assess and use. Can anyone list some elements of metadata?
Source, date of collection, and coordinate system?
Right again! Remember these elements, as they help validate the credibility of the maps we use. The more we know about the data, the better we can trust our decisions based on those maps.

Quick Overview
Standard
National and international standards play a crucial role in ensuring consistency and quality in cartography. The Bureau of Indian Standards (BIS) establishes norms for map layouts, scales, and symbology, while metadata standards like ISO 19115 and FGDC ensure that geographic data is properly described, improving data quality and usability.

National and International Standards in Cartography
In the realm of cartography, adherence to national and international standards ensures reliability, consistency, and quality in representation and interpretation of geospatial data.
Bureau of Indian Standards (BIS)
The BIS sets forth standards that govern various aspects of map making, such as the proper layout, scale representation, and symbology, thus providing a framework that enhances map readability and comprehension.
Metadata Standards
Metadata is crucial in cartography as it provides information about data sources, collection dates, coordinate systems, and data quality. Notable standards include:
- ISO 19115: A widely recognized international standard that outlines how geographic information should be described, ensuring that users can assess the data's suitability for their purposes.
- FGDC (Federal Geographic Data Committee): In the USA, FGDC sets metadata standards for spatial datasets, focusing on improving the accessibility and usability of geographic data.
Thus, adhering to these standards not only enhances the credibility of maps but also promotes better data sharing and collaboration across various platforms.

• BIS (Bureau of Indian Standards) provides map layout, scale, and symbology norms.
Detailed Explanation
The Bureau of Indian Standards, abbreviated as BIS, establishes guidelines and norms for map-making in India. This includes rules regarding the layout of maps, the scales to be used, and the symbols that represent various features on the map. Having a standardized format ensures that maps are clear, recognizable, and easy to interpret by the public.
Examples & Analogies
Think of BIS as a recipe for cooking. Just like following a recipe ensures a dish is made correctly, following BIS standards helps map makers produce effective and understandable maps. If everyone used the same ingredients (standards), the final dish (map) would have a consistent taste (look and feel), making it easier to share and understand.
International Organization for Standardization (ISO) 19115

• ISO 19115: Metadata standard for geographic data.
Detailed Explanation
ISO 19115 is an international standard that deals with metadata for geographic data. Metadata is essentially data about data; it provides essential information that helps users to understand the context, quality, condition, and other characteristics of geographic data. Following this standard enables better organization and accessibility of geographic datasets across different platforms and users.
Examples & Analogies
Consider metadata as the labels on items in a grocery store. These labels inform you about ingredients, nutrition facts, and expiration dates. Similarly, ISO 19115 helps users of geographic data know where the data comes from, how it was collected, and its validity, ensuring they can use it correctly without any misunderstandings.
Federal Geographic Data Committee (FGDC)

• FGDC (Federal Geographic Data Committee, USA): Metadata for spatial datasets.
Detailed Explanation
The Federal Geographic Data Committee (FGDC) is a U.S. government agency that provides standards and guidelines to improve the sharing and access of geospatial data. Just like ISO 19115, FGDC focuses on the metadata but is tailored specifically for the needs of U.S. federal agencies. By creating and following these standards, the FGDC aims to enhance data interoperability, allowing different agencies to use and understand each other’s geospatial data effectively.
Examples & Analogies
Imagine planning a road trip where various states have different rules for speed limits. If all states agree on a common set of rules, it would be much easier for travelers to navigate. FGDC works similarly for data, setting common guidelines so U.S. federal agencies can easily share spatial datasets without confusion.
