One of the best reasons to use a GIS is to unearth and analyze the geographic components of your data. Using geographic tools, you can create bands (buffers) around map features, create districts, define areas of influence, perform surface analysis, and create density grids. TransCAD also makes it easy to overlay and aggregate data and calculate statistics.
Ask and Answer Geographic Questions:
Where are areas with the highest population density? How many people live within one, two, and three miles of a transit stop? TransCAD answers these and many other types of questions. You can integrate census statistics with your own data to identify geographic characteristics that impact you and your operations. You will be amazed at how quickly you can enhance your decision making using this easy-to-use GIS tool.
Automatically create rings around any number of map features and then analyze the characteristics of those areas. Find out how many people live within a certain distance of a transit stop, compute the demographic characteristics around sites, analyze the neighborhoods most affected by noise pollution from a highway, or determine accessibility to facilities.
Create territories based on a table or Excel spreadsheet of data, interactively by clicking on features in a map such as postal areas, or manually by drawing whatever boundary lines you require using the Maptitude editing tools. It is also possible to create overlapping territories or territories based on streets. Your territories can be stored natively in Maptitude or in formats including Shapefile, Oracle Spatial, or SQL Server Spatial.
Determine the areas closest to each of your facilities by building areas of influence, then estimate the attributes within each area to determine areas that are under- or over-served.
Visualize point data by transforming the points into a regular grid. This makes it easy to identify customer concentrations, vehicle hot spots, or disease outbreaks. In addition, the grid can be weighted based on a value you choose. For example, find concentrations of commercial properties that are weighted by the number of square feet.
Analyze and display surfaces on a two-dimensional map or as a 3D map. You can create contour maps of elevations and then determine the viewshed for any location, either at ground level or at a particular height. You can also create surfaces that represent data values, such as measures of air pollution or radon, over a geographic region.

Maptitude contains many geographic analysis tools if you do not require the advanced transportation planning modules and utilities in TransCAD.
