MIKE 11 GIS for ArcMAP

The 2007 DHI Software release includes a completely new version of MIKE 11 GIS for ArcMap. This represents not only a rebuild of the previous ArcView 3.x version, but also a new approach to integrating MIKE 11 within a GIS environment.

MIKE 11 GIS is now a system whereby many of the tasks associated with setting up MIKE 11 hydrological and hydrodynamic models can be executed within ArcMap, as well as providing tools for timeseries management. Whilst not replacing the MIKE Zero interface, it allows users to create and build river networks and cross section databases within ArcMap. The full power of the GIS can therefore be leveraged when developing models, particularly when using LiDAR or DEM data for floodplain modeling and mapping.

 

 

 

MIKE 11 GIS for ArcMAP includes the following tools:

Digital Elevation Model
- Load DEM from various sources.
- Generate DEM based on X/Y/Z point data.
- Process and correct DEM for subsequent automated river and catchment delineation.
- Save DEM as 2D (.dfs2) file for use in MIKE 11 and MIKE Flood.

Branches
- Digitize river branches and embankment lines.
- Use existing GIS data sets as river branches or embankment lines (markers 1-5)
- Automatically generate river branches based on DEM slopes.
- Save network as .nwk11 file for use in MIKE 11.

Cross sections
- Digitize cross section lines and extract cross section data from DEM
- Automatically generate cross section lines at equidistant distance along river branches.
- Generate cross sections based on X/Y/Z data points (typically from GPS river survey).
- Import existing cross sections and clip or and extend onto flood plain from DEM data.
- Save cross sections as .xns11 file for use in MIKE 11.

Hydraulic Structures
- Digitize or define the location of hydraulic structure such as weirs, culverts, bridges, dams and control structures.

Catchments
- Digitize catchments from DEM.
- Automatically generate catchments based on DEM slopes.
- Edit NAM parameters for catchments.

MIKE 11 GIS also provides modellers tools for visualising and analysing MIKE 11 simulation results such as time series and flood maps.

Time Series Data
Time series analysis and presentation in MIKE 11 GIS uses DHI’s Temporal Analyst (TA) extension for ArcMap. TA is designed for managing, viewing, querying, analyzing and editing time-series data from within the GIS. The time-series data may exist in a variety of formats including an MIKE 11 result files, .dfs0 files, ESRI geodatabase or other external databases. TA brings all of these data formats together into a single environment from, where they can be plotted  and further analyzed using a range of built-in sophisticated spatial and temporal tools.

Flood Maps
The generation of 2D flood inundation extents was introduced as a standard feature of MIKE 11 in 2005. MIKE 11 GIS provides some additional tools for mapping of flood storage areas. The generated flood maps are saved in DHI’s 2D (.dfs2) format, which can be loaded into ArcMap as grid/raster data as if they were regular grid data in ArcMap.

MIKE 11 GIS is implemented as a standard ArcMap extension, providing users with a separate toolbar and menu system for interfacing their MIKE 11 models.  The software comes with a range if examples ready to run and a detailed user manual.

MIKE URBAN: Smart wizard for the Import and Export tool

The powerful capabilities of import and export tool were a bit cumbersome in the previous versions of MIKE URBAN. We have therefore concentrated on developing an easy-to-use wizard, guiding the user through all possible import and export options. The new wizard helps you select one of the predefined types of import or export or define the new one (e.g. import data from shapefiles), helps you define the data dictionary (e.g. matching attributes), provides easy access to the frequently used options. The "old type of import and export" is still available (under Advanced Import and Export) and it gives you access to complex data transfer definitions such as definition of look-up relations, for example.

Map Asia 2007 – 6th Annual International Conference And Exhibition on Geographical Information Technology and Applications

The Asia and Pacific region is the largest developing region in the world in landmass, population and aggregate income. Its 48 countries have nearly three fifth of the worlds total population. Each country in the region abounds in rich natural capital and has comprehended the true potential of Geospatial information in leveraging this capital to its utmost economic viability. The Asian region is forging a path of development and economic growth as a function of establishment of infrastructural capital. The region demands and offers scope for application of the various Geographic Information technologies like GIS, GPS, Remote Sensing and Imaging.

 

To meet the requirements of the Geo-informatics community in the Asian region, every year Map Asia raises a platform for the Asian Geo-informatics community to realize, and reveal the stages of dissemination of Geospatial Information.

 

Map Asia leverages an international initiative aimed to provide an apt platform for the convergence, sharing and use of Geospatial technologies. Founded in the year 2002, Map Asia is the largest Annual Asian Conference and Exhibition in the field of GIS, GPS, Aerial Photography and Remote Sensing.
