  • How can I limit the import bounds of a Spatial_DB table?

    You can now use the following parameters to limit the import bounds on the IMPORT_SPATIAL_DB command:
    • LAT_LON_BOUNDS - specifies the bounds to import in latitude/longitude degrees relative to the WGS84 datum. There should be 4 values in a comma-delimited list following the parameter name. The values should be in order of westmost longitude, southernmost latitude, easternmost longitude, northernmost latitude.
    • LAYER_BOUNDS - specifies that the import should use the bounds of the loaded layer(s) with the given filename. For example, to import to the bounds of the file "c:\test.tif", you would use LAYER_BOUNDS="c:\test.tif". Keep in mind that the file must be currently loaded.
    • LAYER_BOUNDS_EXPAND - specifies that the operation should expand the used LAYER_BOUNDS bounding box by some amount. The amount to expand the bounding rectangle by should be specified in the current global projection. For example, if you have a UTM/meters projection active and want to expand the bounds retrieved from the LAYER_BOUNDS parameter by 100 meters on the left and right, and 50 meters on the top and bottom, you could use LAYER_BOUNDS_EXPAND="100.0,50.0". You can also specify a single value to apply to all 4 sides, or supply 4 separate values in the order left,top,right,bottom.

  • Create KMZ with URL-based Thumbnail and Metadata?

    I want to use geotagged JPEG images to export a KMZ file which displays the thumbnail image via URL (instead of embedded thumbs), plus the following metadata (below). Is there any way to do this via Global Mapper? If not, does anyone know of a PC app that can do this?  Even better if it generates the thumbnail images (which will then be uploaded to cloud or server). I use Houdah, which works great, but it is Mac based.

    File Name
    Latitude, Longitude

    Many thanks for any suggestions!

  • Is it possible to change vector search from Version 20 back to version 19 or any other version?


    The new Search Vector function is more powerful than the previous one, and that has introduced some complexity. I agree that it would be a good idea to produce an instructional video about how it works. I have passed that suggestion along to the support team.  The new Search Vector was covered in the webinar for Global Mapper 20 (at about 10:30 and 26:00). It is also described in the Help (look for 'Search by Attribute' in the Index.)

    Generally, getting results similar to those from earlier versions requires use of the LIKE function, which will match attribute values against a string that contains wildcard characters ('*' to match any number of characters, or '?' to match as single character.)  For example, if you want to find all instances of ATTR1 that start with "abc", you can use this search query:
    %ATTR1% like 'abc*'
    The comparison operators (=, >, >=, etc.) work the same as they did earlier. To find all of the features with elevation greater than 200, use:
    %ELEVATION% > 200
    Is there something more complicated that you are trying to accomplish?

  • Linking Lines and Points?

    There is a new feature just for that in v13. You can select your points with the Digitizer Tool then right-click and select the option to connect those points to the nearest line with lines, then you will get lines connecting each of those points to whichever line it is closest to.

    Let me know if I can be of further assistance.

  • 3D view not displaying coincident linework correctly (offset linework issues)


    I suggest that you contact Blue Marble Support directly via email ( to address this. Please include a detailed description of your work flow, and data (CAD and DSM) that will reproduce the problem.

  • HEC-RAS geometry export

    I would like to reinforce the value of the toolset described by the previous posters. The Army Corps of Engineers developed various softwares including HEC-HMS and HEC-RAS which are free to download and widely used in the technical community by hydrologists and hydraulic engineers. The software packages are fairly simple and are accompanied by spatial data editors (HEC-GeoHMS and HEC-GeoRAS); however, the *Geo* applications are only really available as build-ins to ARC which, aside from being cumbersome and crashy, is also outrageously expensive.

    I believe, and I expect that many would support this sentiment, that the inclusion of *Geo* editors for HEC-HMS and HEC-RAS in the Global Mapper software would actually improve your bottom line. As the *Geo* editors are already coded and available for free I'm fairly confident it would not be a significant challenge for your coders to retrofit them into Global Mapper.

    Please let me know if you'd like more info regarding this statement. Again, I would like to strongly reinforce the value of adding this toolset to your [already amazing] product.
  • HEC-RAS geometry export

    Hello All,

    We are finally getting around to adding some HEC-RAS integration in to Global Mapper and were hoping for some customer input.

    We have noticed that the cross-sections for streams don't seem to have a consistent spacing or geometry. Are the cross-sections typically drawn by hand, or is there some automated way that cross sections could be placed along the stream path?

    Once you have a cross section and the Z values along the cross section are pulled from the underlying DEM data, are those Z values typically edited within the stream where the DEM has a flat surface to get bathymetric heights? Or is there some source of terrain with the bathymetry for streams along with terrain surface heights?

    Finally, are the bank locations for each cross section typically specified manually, or is there some automatic way to calculate those based on the stream geometry.

    It would be helpful is discussion for this could be sent to as well as posted here.

  • HEC-RAS geometry export

    Hi Guys,

    Thank you for your enthusiastic feedback and requests, I have linked this thread in the enhancement request. I will also ask if our Sales and Development Staff can discuss the request for compatibility with HEC-HMS and HEC-RAS applications in an upcoming planning meeting, as far as real development requirements and the potential utility for those professionals working in hydrology and hydraulic engineering fields is concerned.

    If you would like me to add any additional information to the enhancement request; use-case scenarios, your own information and professional credentials, and/or supporting or pertinent literature or projects you may send these to

    Please put 'Attn Jasmine - Hydro # 9104' in the subject field, so that I know what it is pertaining to.


  • Is there a quick way to reverse a fly-through path that is based on a line feature?

    Select line with edit tool. Right click. Select Vertex Editing and then Reverse Order of Vertices.
  • Global Mapper v12.00 Beta 2 Now Available

    Global Mapper Software LLC is pleased to announce the availability of the second beta of Global Mapper v12.00 at . Just download that file and run it to install v12.00. It will install alongside any existing Global Mapper version, so you don't have to worry about losing what you're currently working on.

    Among the numerous significant changes since v11.02 in this second v12.00 beta are the following:
    • Added built-in access to the NAIP color high-resolution imagery for the entire United States via the File->Download Online Imagery/Data menu command.
    • Added built-in access to the ASTER GDEM terrain data at 1.5 arc second (~45m) resolution for the entire world via the File->Download Online Imagery/Data menu command.
    • Added built-in access to premium Parcel data for the entire US via the File->Download Online Imagery/Data menu command.
    • Added support for automatically delineating stream networks and watershed areas using loaded terrain/DEM data using the File->Generate Watershed menu command.
    • Added 'Point Styles' tab to Options dialog for vector layers with point features allowing users to setup the styling of points in a layer. Now users can use the default type-based styling, apply a single style to all point features in a layer, setup an attribute-based styling system that styles the points based on the value of an attribute value or the display label, or randomly assign colors to the dot or custom symbols for points in a layer.
    • Updated the Download Online Imagery/Data interface to group data sources to allow easily finding data sources of a particular type or covering a particular area.
    • Updated the Control Center to support assigning groups to selected layers via the right-click menu. Those groups can then be collapsed in the Control Center to allow easily selecting, closing, or hiding/showing that group.
    • Added new right-click option to the Digitizer Tool for creating a regular grid of areas anchored at some point and of user-specified size, rotation angle, and naming.
    • Added ability to export BIL/BIP/BSQ and JPEG2000 raster files with multiple bands of data at 8, 16, or 32-bit depth (similar to what was possible before for GeoTIFF exports).
    • Added option to use “halo” fonts for text display. Halo fonts display a thin border around text of a slightly different color, making the text visible on any background.
    • Updated the export interface to replace the long sub-menus with dialogs allowing format selection to prevent overflowing the export format lists off of the screen.
    • Updated the map legend display based on vector types to allow labeling each style in the legend by the feature type, name, or any attribute value, in addition to the feature description which is what was always used before.
    • Added new EDIT_VECTOR script command (replacing the ASSIGN_TYPES command) to allow adding/updating feature attributes values and display labels, reclassifying features, rotating/scaling/offsetting feature coordinates, or marking features as deleted by searching loaded features for matches against their attributes/label values and/or types.
    All of the other numerous changes are listed in the What's New document that is displayed during installation.

    Prior to the v12.00 release we also plan on continuing to improve the new watershed delineation feature and adding ARCS (British Marine Chart) import support.

    Here is a temporary registration key so that you can try everything out in the beta for 14 days:

    RegName: DEMO_09282010
    RegCode: 1070750785

    While we plan on officially releasing v12.00 in about 1 week, for those of you that just can't wait to purchase new licenses and upgrades to existing licenses, you can purchase those now from . Pricing for upgrades from v11 is $129 US per license and pricing for new licenses are $349 US for a single license with price breaks for multi-license purchases.

    Let me know if you any problems or questions.
