Use BORDER_COLOR attribute for fill colour of area features

sphillips — Fri, 05 Apr 2019 16:01:00 +0000

Hi,

Is it possible to use the BORDER_COLOR attribute as the solid fill colour in the Area Styles tab under Apply Same Styling Based on Attribute/Name Values?

Essentially I would like to style my polygons with a solid fill (with no border) using the attribute data gleaned from using the Add Style Attributes to Selected Features command . It only seems to allow me to use this value as a border colour and not a fill colour.

For background info I am trying to find a workaround to import the solid hatches from CAD drawings into Global Mapper whilst retaining the colours. Currently it converts solid hatches into TIN Face Areas. I have tried creating a new attribute called FILL_STYLE and setting them to Solid and then creating a new attribute FILL_COLOR and passing the BORDER_COLOR values to it using the Calculator. When I try to use these attributes I still end up with coloured borders.

Any ideas would be very welcome.

Cheers,
Steve

Create line with vector/dot every 50m?

rotoview — Mon, 01 Apr 2019 13:51:40 +0000

Hello.
What tool and/or adjustment do i use to draw a vector based line with a vector or vercitie every 50 m?
Want to visualize a "power line" for a costumer and "just want to do it simple" and not measure every power tower. I just want to make the line with a specific setup and GM should do it automatic.
Suggestions?

3D Viewer not working after driver update

david_recon — Thu, 28 Mar 2019 00:19:32 +0000

Hello,

I recently installed GM20.1 and have been running the Pixels to Points tool testing it's capabilities. I am running through editing the classification of points in the point cloud, but my 3D view won't pull up anymore. This makes it difficult to find changes that need to be made. When I click the button, I don't get anything as if I haven't even clicked. I'm running a Dell Precision 5520 (Windows 10), purchased about a year ago. I updated drivers yesterday, which seems to roughly correlate to the time 3D view stopped working. I have both Intel HD Graphics 630 and NVIDIA Quadro M1200 cards showing up under Device Manager>Display adapters. Any assistance would be greatly appreciated.

Thank you,

David

Changing lines simultaneously when using the buffer feature

curves — Fri, 29 Mar 2019 16:35:15 +0000

I am using the buffer feature to create landscape patterning which is associated with the contour lines of a particular landscape. I use the buffer tool to reproduce a number of lines after I have meticulously created my line feature which has to run at a certain percentage off-contour. Once this is achieved I replicate this line to see how it behaves when compared to all the other contours. Most of the time I have to make corrections to the original line feature. My question is, is there any function that will automatically update all the lines within the buffer after I correct the original line? At the moment I have to keep reproducing another set of lines using the buffer tool.

Test if one layer overlaps/is within another layer

veddycent — Wed, 27 Mar 2019 12:56:59 +0000

Hi all,

Is it possible, via scripting, to test if 1 layer is within/overlaps another layer?

Some context:
I'm loading a bunch of files(shape files, DTM and TIF) into GM which already contains a layer with an irregular area. I'd need to test if the loaded files overlaps/is within the irregular area, if it is I keep the layer if it is not I unload the layer.

I haven't found anything in the scripting docs which brings me here.

There was a similar question asked a while ago but never got a reply:
https://www.globalmapperforum.com/discussion/13622/selecting-using-gm-script

Any feedback would be much appreciated.

Problem with GM19 software distribution

Yann DUPUY — Tue, 26 Mar 2019 11:08:40 +0000

Hello,

we tried to distribute our software which relies on Globalmapper 19.

My client have a crash within Globalmapperinterface64.dll (exception code 0xc0000005).

It only works with Globalmapper 16 (I give the same piece of software, only setting the correct distribution key and delivering the version 16 something DLL).

What could be wrong with globalmapper 19's dll ?

Thanks,

Hi everybody,

Please I would like to know how can I do the computation of 3Dsurface/area on a digital surface model/digital elevation model ?

- what is the better tool to use ? I try with attibutes and fill volumes but both results are no coherent.

Second question, how can I apply a fonction in scale path profile ( ex. log in Y or X axis )

I use Global mapper 20 (64bit)

Many thanks for your explanation,

Calculate heading of buildings (areas) into attribute table

MatsW — Sat, 23 Mar 2019 19:22:29 +0000

Is there a way to calculate the bearing for the longest wall on a number of buildings (area) and get these values in the attribute table? The direction of the longest wall could be based on the vertex point which is counted as 1. If, in the same calculation, one can convert the respective building area to a point that gets the bearing, it would be optimal.

Site flatten - top down

TXPE — Mon, 18 Feb 2019 21:13:11 +0000

I am attempting to show/create an excavated hole in the ground. The existing ground surface is in the 500-530' elev range the hole will be dug to a depth of 400' elev. The excavation boundary at the surface is constrained to a defined boundary. Therefore, the excavation needs to be inside this line. Wall slope is 70 degrees.

I draw the area to represent the limits of excavation at the surface, select that area, then do the Calculate Flattened Site Plan Grid option. The resultant grid surface is drawn such that GM apparently sets the boundary area at 400' and works it way back up (bottom up). I need it to work top down as shown by the green line in the screenshot.

I've tried the various options and none will seem to do what I want. Any recommendations?

UNLOAD_LAYER unloading all instances

veddycent — Thu, 14 Mar 2019 18:23:19 +0000

Hi all,

I'm trying to unload a group via script but seen as there is no way of doing that (not that I'm aware of) I'm looping through the group and unloading each layer one by one. Unfortunately this closes every instance of that layer, even when the instances which are in different groups.

Here is the script:

LAYER_LOOP_START FILENAME="Group2_*.shp"

UNLOAD_LAYER FILENAME="%LAYER_FNAME_W_DIR%"

LAYER_LOOP_END

This is the hierarchy structure:
Group1 - Start
---Shape file 1.shp
---Shape file 2.shp
---Shape file 3.shp
Group1 - End

Group2 - Start
---Shape file 1.shp
---Shape file 2.shp
---Shape file 3.shp
Group2 - End

After the script finishes all layers have been closed.

I haven't found anything in the documentation or on the forums, am I missing anything?

Updating/adding data to an existing gmmp. file

Joey — Thu, 21 Mar 2019 13:34:39 +0000

Hi Guys,

Does anyone know of a way to update or add data to an existing gmmp. file without having to extract the gmmp. file from the tablet, add data, save as a workspace and then export as a new gmmp. file? Last time I did this my geotagged photos did not transfer from the gmmp. file to the gmw. file and now I cannot add them into the new gmmp. file. It would be real useful if I could just edit the data in the gmmp. file on my desktop and transfer the same file back to the laptop. I'm probably missing something here but a good answer would save me buckets of time. Thanks.

Changing how dip angles are displayed

aspatz — Sun, 17 Mar 2019 17:58:50 +0000

Hi,

I am displaying strike and dips on a geologic map, with the dip angle being shown. However, The dip angles displayed aren't centered with their corresponding symbol. Is there a way to fix where the dip number is displayed on the map?

Also I've been trying to change the size of the text for the dip angles but have been unable, so any advice with this would be appreciated as well.

Thanks,
Drew

Can GM open a DTM file from PDS (Teledyne)?

Finley — Wed, 20 Mar 2019 17:27:53 +0000

I have a Digital Terrain Model grid file I would like to be able to open and work with, i.e. export as an ENZ ASCII.

Can Global Mapper work with these file types?

I would attach a sample file but uncertain how.

multi-processor/core support

macsmith — Sat, 03 Feb 2018 15:43:25 +0000

I've just compared the speed of GM with Qgis and got a surprise result. I loaded a 99,000 point KMZ into an otherwise blank canvas in each GIS. I then panned slightly and timed how long it took to refresh the display.

Initially I got what I expected, a paid for GIS product (GM) was faster than a free GIS (Qgis). GM took 101 seconds and Qgis took 530 seconds.

However, I then discovered a setting in Qgis which enabled multi-core support. Re-running the test for Qgis, it refreshed the display in 13 seconds, leaving GM in the dust!

I know there is some (limited) support in GM for mult-core operation but can we please have this support significantly widened to include common operations such as panning/redrawing?

How can i select some point from txt file using formula operator and delete by CALC_ATTR_FORMULA ?

DANBRI — Tue, 19 Mar 2019 09:22:38 +0000

Hi all
I have an RMSE report in "csv" format obtained by LIDAR_COMPARE based on a "txt" format 3D control point file

using CALC_ATTR_FORMULA in the scripting language, I need:

1. To eliminate all the points that have an RMSE> = 3 * "global_RMSE" in the RMSE report "csv" and edit the 3D control point file by eliminating the same point.

2. Recalculate a new global RMSE with the new 3D control point file and generate a new report.

We had erased our computer where the Global license was, without removing the license

AYAREL — Tue, 19 Mar 2019 08:09:21 +0000

talking with your technical support, you inhabilitated the license from your data but, a few months ago, our returned again, demanding two licenses active, when a computer doesn't exist.

Now, we dont have any licese because of this problem and, updating to another newly version isnt an option as well as our current version give us whatever we need

speed improvement in watershed calculation

JSL — Wed, 13 Mar 2019 05:20:28 +0000

Hi, I see that v20.1 has improved the viewshed calculation, and I know that contour generation was improved a few versions back. I would really love to see improvement in the speed of watershed calculation. I use a lot of high resolution DEMs, and I'm limited in the size of the window I can use because the computation power necessary for watershed generation process increases exponentially as I zoom out. So if you're looking for a place to increase speed, this would be a great one!

Thanks...

Global Mapper Mobile auto-record GPS

Joey — Tue, 12 Mar 2019 08:01:05 +0000

The auto-track GPS is really useful. I have my GPS auto-track set to record a point every 30 seconds however, I am wondering if I can extract the time the point was measured as an attribute. Currently I can only view attributes for lat/long and elevation. Any help would be much appreciated!!

problem recreating measure attributes in v.20.0

JSL — Sat, 09 Mar 2019 13:33:46 +0000

Hi, I discovered that if I rename the "Bearing" or "Length" attributes to a new attribute that begins with the attribute, like "Bearing One" or "Length One", v.20 will not recalculate the attribute and create a new "Bearing" or "Length" attribute if I try to add/update the measures. I had to rename it so another word is in front of "Bearing"/"Lenght", like "Test Length" or "Test Bearing" before it would create a new Length or Bearing attribute.

However, v.18 has no problem with this. Not a huge problem, but it was annoying until I figured out what the problem was.

Export layers as files

Transferring GPS data from global mapper mobile

Joey — Sun, 10 Mar 2019 08:39:00 +0000

Hi Guys,

I am using Global Mapper Mobile to collect data in the field, and I am using the 'GPS auto-track feature' to track my position. I have the auto track feature set to record my position every 30 seconds however when I transfer the GPS data to my desktop the time of the position recorded is not an included attribute. This is important as I need to correlate the time of the GPS position with measurements taken in the field. Is there anyway I can include the time of the GPS auto track position as an attribute when I transfer the data over? Any help is much appreciated.

3D view not working/laggy in GM ver. 20

HEC-RAS geometry export

DustyRobinson — Thu, 08 Dec 2011 16:06:23 +0000

HEC-RAS (Hydrologic Engineering Centers River Analysis System) put out by the US Army Corps is a freely available software package used for hydraulic modeling of rivers. It is the primary software package used all over the nation for floodplain mapping related to FEMA and NFIP. It is also used for a lot of other work involving rivers such as designing bridges, culverts, river restoration projects, canals, ...

It does it's job, but it is severely lacking in working with geographic data. So, to get a model setup most people use other software such as AutoCAD, MicroStation, or AcrView (HEC-GeoRAS).

My suggestion is to incorporate something similar to HEC-GeoRAS into GlobalMapper. If done well there is potential for a lot of users.

All that is really needed are the following;

Ability to work with various terrain datasets
Ability to draw lines
Ability to extract terrain data and distances from these lines
ability to export to a specific file format for HEC-RAS

GlobalMapper is already setup to do all of those. The only step remaining is creating the file ready to be imported into HEC-RAS. Since HEC-RAS is public software I think you can obtain the needed information for this file.

While this would be a great starting point, GlobalMapper has the potential to post process data that HEC-RAS creates. Such as creating flood inundation maps, depth plots, scour plots,.... But I will save that for later.

Highlight layer of selected feature(s)

sphillips — Fri, 08 Mar 2019 09:25:40 +0000

Hi,

When using data from CAD sources with hundreds of alphanumeric layers it would be useful to be able to select objects of interest with the Digitizer Tool and have the layers highlighted. Using the Feature Info Tool makes for a very slow process of reading the layer name and then searching through hundreds of layers for the layer of interest.

If this is already possible I'd love to know how to do it.

Cheers,
Steve

3D Viewer Crash GM 20.0

I am using Win 10/64 with 32 GB of memory. I am unable to utilize the 3D viewer, and crashes within seconds of clicking the button. I am not loading any particularly large file formats, localized LIDAR and some vector data. No matter what I load or do, it always crashes. Any help is appreciated.
