TransCAD Geographic Analysis Tools

Unearth the trends and information hidden in your data

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.

TransCAD ring map with calculated attributes

Rings (Buffers/Bands)

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.

Territories

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 editing tools. Your territories can be stored natively in TransCAD or in formats including Shapefile, Oracle Spatial, or SQL Server Spatial.

Drive-time Territories

Drive time partitions allow regions across a line layer to be defined based on network cost. Identify accessibility to transit stops, businesses, emergency services, and more. Partitions can be based on drive time or based on distance.

TransCAD heat map of customer concentrations

Hot Spots and Heat Mapping

Visualize point data by transforming the points into a regular grid to identify hot spots and weight the grid based on a value you choose. For example, find concentrations of commercial properties that are weighted by the number of square feet.

Spatial Queries

Filter features based on geographic location, proximity to other features, by radius, by pointing, by polygon, or based on a value or condition.

Measuring Tools

Create a table that shows the drive time or distance, or Euclidean straight-line distance, of features from one or more origins to one or more destinations.

In addition you can:

Measure areas and distances
Find weighted centers
Aggregate and disaggregate attribute data
Create areas from line features or lines from area features
Filter features based on level of adjacency
Create lines from a series of point features
Filter features by pointing, radius, polygon, condition, value, or location
Generate statistics (count, sum, mean, minimum, maximum, standard deviation, one-way and two-way tabulations, and more)
Identify neighbors to an area of interest and create bands of adjacent neighbors
Analyze and display surfaces on a 3D map
