ISIS Mapper

ISIS Mapper is an analysis and visualisation tool for spatial data. It is designed to be compatible with ISIS and TUFLOW model data, enabling these to be viewed interactively alongside other GIS data.

Users are able to produce flood maps and animated flood sequences. Modellers can extract information from spatial datasets to use in model building.

ISIS Mapper is compatible with many commonly used GIS data types and provides both two and three-dimensional viewing options to enable the most appropriate level of interaction for your needs.

Flexible colour legends and hill shading assist with visualisation of fine detail in complex datasets such as LiDAR ground models.

Images, such as digital maps and aerial photographs, can be viewed in two dimensions or draped over surface grids to create a three-dimensional view.

Key features

no additional software required to build a model in ISIS Professional and or ISIS 2D
enables 2D model building from spatial data
ability to view ISIS and TUFLOW model results, including ISIS binary results (ZZN), ISIS TabularCSV, ISIS 2D and TUFLOW output scalar data, such as flood depth grids and ISIS 2D and TUFLOW output vector data, such as velocities
create river cross sections and extend surveyed cross sections onto the floodplain
create ‘reservoir’ and ‘spill’ units
create animations from ISIS or TUFLOW model output data overlaid on GIS map layers
the ability to view various GIS data, including grids (FLT, ASCII grids and ESRI), images (TIFF, GeoTIFF and JPEG) and vectors (ESRI Shapefiles, CSV point data and ISIS Mapper native triangular network)

ISIS Mapper supports the generation of water surfaces from both ISIS and TUFLOW model results. Assigning one-dimension model results to an ISIS Mapper native triangular network and interpolating enables points to be mapped onto a three-dimensional surface. Displaying this data in conjunction with other GIS data allows the creation of flood maps. These can then be used to show property locations and how they interact with floodwater as levels vary over time.

ISIS Mapper is included as a free visualisation tool within ISIS Professional and ISIS 2D at no extra cost. It is also included within ISIS Free, so it can be used to help build new models and view or process model outputs in parallel with simulations run on other computers.

ISIS Mapper can export flood mapping outputs directly into Google Earth format. This provides further options for visualising and sharing results.
