Instruction: What is a graph?

Response: Graph is a set on nodes that are connected via edges. Edges represent the relationships between the nodes and can have multiple properties like weight or sign. For example the weight of the edge can represent how strong are the relationships between the nodes A and B, while the sign might represent wether these relationships are positive or negative.


Instruction: Tell me about the various road types in USA?

Response:
The public road system in United States of America is primarily made up of Highways and Local Roads. The United States Department of Transportation's Federal Highway Administration (FWHA) classifies roads based on functions which are created based on attributes such as speed limits, route length and spacing. Based on the road functions we can categorize roads into the following categories.
1. Interstates and Arterial System
2. Other Arterials
3. Collectors
4. Locals

The interstate system is the at the top of road function classification system. They include Highways and Freeways with the highest speed limits and which allow for long distance travel without a lot of interruption. They are constructed using precise standards, signage and with safety considerations. They are also sometimes referred to as Arterial roads as they provide vital connectivity across regions in America. Interstate 95 or I-95 is an example of one such highway in the east coast of the United States which runs from Florida to Maine. The Principal Arterial system also comprises of U.S. Highways, which provide connectivity across regions which do not have an Interstate to support travel.

Other Arterials also include freeways and highways which supplement the Interstate system explained above. They have a slightly lesser speed limits. They typically connect cities and urban areas. Consider them as being minor highways. As an example, North Carolina Highway 55 (NC-55) is a primary state highway artery connecting multiple regional and urban areas in the state of North Carolina.

Collectors are critical for connecting urban population using local roads with the Interstate highways where applicable. They have more interruptions and are shorter in lengths. They also have lesser speed limits (30-35 mph). These can comprise of State highways which connect local roads with the Arterial highways.

Finally local roads provide connectivity between communities, regions, farms and other local areas. They form the lion's share of the United States road system.


Instruction: What is the difference between a road bike and a mountain bike?

Response: Road bikes are built to be ridden on asphalt and cement surfaces and have thin tires, whereas mountain bikes are built to be ridden on dirt and have wider tires. Road bikes also have more aerodynamic handle bars while mountain bike handle bars a built for less responsive steering while bouncing around off the road.


Instruction: How does GIS help in the real estate investment industry?

Response:
Real estate investors depend on precise, accurate location intelligence for competitive insights about the markets and locations where they do business. Real estate investment teams use GIS to bring together location-specific data, mapping, and visualization technology. This enables them to provide the latest insights about real estate markets and their investments, now and in the future. Using thousands of global datasets, investors can quickly understand how their real estate investments are performing across town or around the world, quickly access precise local data about real estate assets, on any device, anywhere, anytime, including information on occupancy, building maintenance, property valuation, and more.

Real estate companies and investors use GIS to research markets, identify new opportunities for growth and expansion, and manage their investments at the market and neighborhood levels. They can also use GIS to create professional digital and printed materials—such as 3D renderings and virtual walk-throughs—to help market investments across platforms. Real estate investors can use mobile data collection tools to gather property information directly from the field and analyze and share insights across their organizations in real time. Investors can leverage precise local knowledge about their assets across geographies. GIS maps and dashboards help investors see, in real-time, relevant data that can affect properties, and streamline investment management with access to all relevant data about every asset in any portfolio.
