Dynamic urban mapping
Introduction
Interactive map is that cartographic representation developed in computational environments that combines the map with the capacity for interactivity on it, which allows the user to move, zoom, activate or deactivate geographic information layers "Layer (geographic information)"), consult embedded information, along with those capabilities that the development method offers.
Thus, through computational environments, links are established to other types of statistical data presentations or graphic techniques other than traditional maps, which allow information to be transmitted about the spatial arrangement of the data and how that information is related to other attributes "Attribute (computing)").[1].
Characteristics
The ability to zoom, to adjust the size of the viewing area according to interest, is equivalent to having the map at the scale "Scale (cartography)") appropriate for the visualization of details or general vision, which, together with the possibility of activating geographic information layers "Layer (geographic information)"), if offered by the interactive map, allows the generation of accessible thematic maps at the desired level of detail, through the interaction capacity that computing devices offer.
On this map it is possible to place markers, generally in the form of an "Icon (computing)" icon, but also points, lines or areas, which can be linked to reference data, information of various types - textual, graphic, multimedia, hyperlink, among others - that will be loaded at the user's request, one of the fundamental elements of interactivity, hypertext, electronic documents, since it is a digital map.[2].
Structure
Interactive maps are stored on servers, generally web servers, which are accessed by the user, human or machine, and these maps can be integrated into web pages without any notion of discontinuity, as they are incorporated into textual spaces, any space, and integrated into them, through the appropriate programming resources, such as the use of iframe, which allows a transparent embedding for the user.[3].
A specific case is spatial data servers that can provide real-time database connections (relational or object-oriented databases) for multiple "Client (computing)") GIS clients, servers different from traditional file servers, being essential for the establishment of comprehensive Spatial Data Infrastructures.[4].
