When you look at a map we doubt you really see or better yet understand what it really contains. That’s totally understandable. We want to take you though the finer details behind the map. Don’t worry we will keep things general so you get the basics.
Behind the Map
All maps start with data. Most people always forget the first step and it’s the most important. Behind that map is a database that drives what you can do with the map. Points, Lines, Polygons are all vector based along with imagery or raster data. Raster and vector data are combined into one.
Deeper into these data types is the real important part. Each vector or raster data type has a full database supporting it. For a point one example could be a business and all the associated info regarding that business. Name, Address, Sales Volumes, Employees and Products Sold. A Polygon example could be a Zip Code, containing post office address, sq miles, number of mail drops for residential & commercial and population. Raster could be an elevation with each pixel covering a certain ground resolution (maybe 1 pixel covers 3 feet) meaning each pixel has an averaged elevation for the area covered.
Each of these items can be queried, sorted, calculated and asked questions against. This is where having a well built dataset behind the scenes is very important. The more data you have the more questions you can ask it and the better the result will be in your answers.
We spend a lot of time with clients making sure the data side is robust enough for the project at hand. Without that data your map is just an image. Continuing this topic we will dive into the individual parts of what makes a map a map in future posts.
