  • Global Mapper Mobile For Android - Beta on Google Play

    Hi,

    The GPS keeps working after exiting GMM, is it supposed to be that way?. The location icon only disappears when I force close the app from android menu.

    This was done so that accurate location data would be available immediately once the app is brought to the foreground. We are considering adding some options that would give the user more control over how the location services are used. Disabling while the app is in the background, and not recording track data, is among these.

  • Legend Text Displays Strangely

    What platform are you using?  If it is WIN10, then I would check the high DPI settings for GM.  You can do this simply by right clicking on the GM icon and then select properties.  In the properties window choose the compatibility tab.  You will find a box for "Disable display scaling on high DPI settings" and you can toggle the option on or off.  I would try this to see if the issues clears and you may identify any similar issues with any other applications where application fonts appear to be out of focus or look odd -- just my two-cents worth . . .

  • CARIS Spatial Archive (CSAR) files

    Hi,

    I was wondering if Global Mapper and the SDK have plans in the near future to support importing CSAR formatted files. There is an overview of the format at:

    http://www.thsoa.org/hy09/0514A_04.pdf

    though this web site does not provide much in terms of the specifics of the file format.

    Also, I have found a link that the USGS is using them at:

    http://water.usgs.gov/GIS/metadata/usgswrd/XML/pp1798J_Union_Pipeline_20110727_csar.xml.

    Any information you have on possible future support for this format would be helpful.

    Thanks,

  • Slope degree depending on direction

    Hi Sam,

    there has been a quite (quite) big time lag here, but in regards to your above answer, actually my question at the time was not really answered.

    I have prepared two more screenshots from a current project, which might help to illustrate what I am looking for. Basically we are installing large scale solar systems and in such case the North- and South-facing slopes are very important factors. Apart from the shadowing effect (I have some other questions I sent you guys about this right now) it is also about the installation of the system. I am basically using the topo-analysis functions of GM to give me a better idea of how long I need to make the poles that support the system. As the poles are usually installed in two rows, one front and one back pole, I need to now the N-S slope of the ground in order to now how long I need to make those poles. The E-W inclination is only secondary in that regard, as the structure on top can be adjusted accordingly.

    What I am currently doing is what you can see in the screenshot, which is basically just creating section views in NS-direction to check the change in inclination. This is fine, but it is time consuming because I need to analyse each section individually and arbitrary because I have to estimate myself based on the contours which areas I best divide. So if I could color the area only based on the northern slope aspect I would have a very clear picture.

    As an example, the section 1 runs through an embankment of the site, which has an inclination of about 29° in EW direction, but in NS direction it is almost flat.

    The slope direction function does not really help me here either, because it basically colors everything that is facing even slightly in northern direction, but it does not tell me how much.

    So maybe with this information you can let me know one more time if the existing functionality of GM may be able to do something or if you might be able to add something like this without too much effort.

    Thanks and regards, Jakob

  • Unexpected behavior while Generating Contours from GeoTiff data

    Hi Vusal,

    It may help to visualize what GM is trying to deliver when generating your contours. The image below is from your data where I have created a 0m user contour and compared it to your gridded surface when clamped out to a maximum elevation of 0m. What GM does is generate a reasonable contour along fragmented pixel data as shown. Therefore I assume that when you confine the process to a different area the second time around, that each contour might start at different points and therefore take slightly different routes than before. Note that your pixels are 10m and that you are generating 0.5m contours with it.


    Regards,
    Steve

  • Getting Error when launch

    First, make sure you have the latest version of Global Mapper.  If the problem persists in the latest version, please send a description of your workflow, a copy of your data (if possible), and the results to Blue Marble Geographics Support (geohelp@bluemarblegeo.com).  This will ensure that the support team will be notified of the problem and can work on a solution.

  • Batch Process for "Export Mbtile format" for bulk tif images

    Hello,

    You can use the EXPORT_WEB script command in a batch export of MBTiles data.  If you are new to Global Mapper scripting, we have an introductory, prerecorded webinar here.

  • Cast shadow analysis

    I am currently wondering about the analysis of cast shadows based on the the terrain.

    My background is, that I am trying to simulate the near shading effects by trees, buildings and other elevated objects onto lower terrain to see if the terrain behind / below will be shaded during specific hours of the day.

    I figured out, that the shaded relief function allows for setting of different sun angles and azimuth and so I tried to work with this. However, it appears to me, that this functionality will only display, whether or not a specific area would in theory receive direct sunlight but it does not cast / show the shadow, which an object will throw.

    So for example, I am attaching a view from a 3D model, where I overlaid three hill shading options. The model is located in Yamagata, Japan.

    Option 1 (10:00 am)
    Sun angle 24.5°
    Azimuth 155°

    Option 2 (12:00 pm)
    Sun angle 28.5°
    Azimuth 180°

    Option 3 (14:00 pm)
    Sun angle 20°
    Azimuth 215°

    I am aware, that the above numbers are not 100% correct, but it is accurate enough for my purposes.

    My point is, that the programm just creates dark areas, where there is no direct sunlight, but it does not cast shadows. In this case, there are two buildings in the centers, which are roughly 30m and 40m high and they would probably cast quite far shadows behind them.

    Is there a way to do this? I would like to see, how far shadow is reaching but right now it seems that the programm is not doing that.

    Regards,

    Jakob

  • Any options to export TIN to LandXML in GM

    I'm running into a strange issue where the land/xml file is reporting as metric, even though all the data and all the settings I have set are US Survey feet. We were not experiencing this issue in earlier builds.

    Thank you for your help-
