How to plotting points on a map

Hi,

Am a new user of Bentley map and i need to produce a map plotted with data points representing water points in different colours. I just cant figure out where to start from? Any basic help will be much appreciated.

Thanks alot!

  • Hi Diana,

    usually the workflow is to use Geospatial Administrator to define features and their properties, placement methods etc. and to export the schema to Bentley Map workspace.

    You did not provide too much information like what is the source of the points, based on what criteria or value the color should change etc, but it seems the points could be defined as point-cell feature, because it's easy to control cell scale if printed using annotation scale and the cell color can be defined e.g. moving to a proper level or using point cell and active color.

    With regards,

  • Hello,
    Could you state what version on Bentley Map you are using (08.XX.XX.XXX)?
    In what format are the data points?
    Please be aware there is a large amount of information on this area found in the Bentley Map HELP under Import.
    Information on Importing ASCII files and GIS data types can be found here.
    Regards
    Derval.



  • Depending on the format of the input data, consider also 'XYZTXT' within MicroStation, then promotion of the elements to Bentley Map features.

  • Diana,

    Derval & Nelson suggest methods of getting the data into Bentley Map.  

    Jan's example is called Property-Based-Symbology, and is defined in the Geospatial Administrator.  In this case the colors are defined for an entire project based on the type of point (the properties or criteria), and any points or Features added to the Workspace will take on the corresponding colored attributes.  Here is how it would look in the Schema for a polygon feature - Building:

    And the results on the Map as they are placed by the Command Manager:

    In your case (imported using Derval's or Nelson's technique) the points would need to be set to the corresponding Feature using the "Mapped Name" field in the Interoperability dialog.  This would automatically color-code them based on the Schema definition.

    If you do use the Import methods suggested, another option for color-coding the points is to use a Thematic display, defined in the Map Manager.  The Class (buildings) or set of imported points in your case, are color-coded by "Type".  Right-click on the layer name in Map Manager and select the Symbology item:

    I hope this shows you a little of how Bentley Map can represent your Water Points in different colors.  Please let us know if you have additional questions.



  • Hello Derval,

    Version of Bentley: 08.11.09.91
    The points are latitude, longitude and then elevation in meters eg 0.13496499999999997, 30.402215, 1184

    So am looking at plotting the various points on a map of the district where these were picked. I have the shape files which i too need to import but these are ESRI files.

    Thanks,

    Diana
