presentation, along with possibilities for integration with digital systems are greater than ever. Consider just three applications of this type of map.
Corridor Projects
In urban environments, when a new alignment is proposed, it often runs through densely populated areas, requiring substantial attention to existing features. Overlaying a proposed alignment onto aerial photos helps viewers to visualize the project’s potential impact. Planimetric mapping makes it easy to see how proposed features, such as light rail stations will fit into the existing landscape. In digital applications, the ability to add, delete or edit the geometry of features can be very useful – especially if this can be done from a mobile device.
Subdivision Layouts
Whether it’s pending review, under construction or built, subdivisions are excellent 2D map candidates. Oftentimes land is divided into taxable lots, and these properties are best visualized from a birds-eye view with some surrounding context, such as streets and parks. GIS (Geographic Information System) software can easily calculate the area of tax lots, and provide the result as a label on the map.
Revamp Projects
When expansion plans begin to take shape, a 2D map provides an excellent visualization tool. Persons already familiar with the area will be able to understand exactly what the plans propose if key landmarks are shown behind bolder, thicker lines that represent the upcoming construction activity. Say an airport needs more parking and at the same time wishes to beautify its access roads. These and other enhancements can be shown on a map without relief. One of the most powerful features of a GIS is its ability to associate attributes with geographic features. Additionally, some organizations benefit from setting up network topology, where relationships between features can be defined and various analyses performed on groups of features.
Planimetric mapping, whether delivered via plot or webpage can easily meet the needs of the producer. Such images or interactive systems can provide information in a way that would be ineffective, if not impossible via spoken word or plain text.
