You can save a layer in the KML format directly from QGIS, just right-click the layer name in the Layers window, click Save As.., and choose KML from the list of file formats:

One of the fastest and easiest possible solutions uses a short program written with the free open source program R (the R project for statistical computing). The following code computes the distance matrix (using spherical distances) between two arrays of (lon, lat) coordinates named customers and facilities and stores it in an array distances (with rows ...

I think you may need to process this file yourself - either manually, or by writing a script to automate the extraction. If you rename the file GMRT.kmz to GMRT.zip you can open it in WinZip or similar, and see its contents. This includes the file doc.kml, which contains a number of Links - examining the first link shows a URL: <Link> ...

Due to various vagaries in the ArcGIS software, I'm going to tell you to use different coordinate reference systems. That will let you access the predefined transformations and hopefully make your life easier. Use WGS_1984_Web_Mercator_Auxiliary_Sphere instead. This one uses WGS 1984 for the geographic CRS (aka datum). The one you're using, ...

Instead of creating a KML file then using that to access Google Earth, you can instead add your GeoServer WMS directly as an overlay as below: From the menu select Add, select Image Overlay, give the overlay a name select the Refresh tab select WMS Parameters select the Add button next to 'WMS Server:' drop down Add the URL to your service (without ...

If you take the G in GIS for Geographic then the answer is no. If you take the G in GIS for Geodetic then the answer is maybe, but not any time soon. There are two main issues with Geoprocessing in the Geodetic domain: 1. Calculations are way more complex, time consuming and uncertain. Take for instance the distance between two points: should it be ...

You can find a statement of the plugin author with a link to the terms of use here: https://www.mail-archive.com/qgis-developer@lists.osgeo.org/msg21665.html Search for "you must not access map tiles" in the TOS (https://developers.google.com/maps/terms). That's why the OpenLayers plugin is using only the Javascript API with a WebKit Browser. My ...

Working (albeit cumbersome) solution to convert KML-/KMZ-files with <gx:Track>-Extension to gpx/csv/tcx, via Googles MyTracks-App. I tried to import a .kmz-file to QGIS, containing a GPS-track as <gx:track>-Element. (Track was recorded with MyTracks-App on Android. I only had the .kmz.) After numerous attempts, using various tools ...

The "Precomputed datasets" can be loaded into the Google Earth standalone client as follows: View the source of the Earth Engine webpage (https://earthengine.google.org/#intro) Search for the galleryMetadata object, which is a list of dataset definitions. Within the galleryMetadate object, the "Precomputed datasets" will have a attribute named "kml" whose ...

There might be multiple crater holes in this area. In a Russian language magazine Science First Hand there is an article that mentions different coordinates, though the pictures look familiar. The coordinates mentioned in the article are 69°58.268'N, 68°22.2'E Below is an image taken as a screenshot from the Russian Federal Space Agency portal that ...

I bet those values are US survey feet, and based on the document, also on NAD 1927, not NAD 1983. The app you're using is using the NAD 1983 definitions of the State Plane zones. The parameters are different, so you're not going to be able to convert NAD 1927 coordinates using it. If I convert the given values (cropping to integers) using the NAD 1927 ...

Your Gauss-Krueger projection uses +datum=potsdam. Up to 2012, this was hard coded in proj4 to a very unprecise value using a 3-parameter-transformation. You find more exact values for 7-parameter transformations in this topic: http://forum.openstreetmap.org/viewtopic.php?id=12723 There is an even better ntv2-grid transformation available here (take the ...

If you need ruler distance, You can use the distance matrix tool in Quantum GIS. Quantum GIS can read your KMZ files. Then you can easily compute the distance matrix. Here is tutorial http://qgis.spatialthoughts.com/2013/04/tutorial-nearest-neighbor-analysis.html

I was able to reach the author of Shp2kml 14 September 2014 and reported the problem with the "The the license for this tool has expired" message (something I first ran into several months ago). On 15 September 2014, he uploaded a newer version of the file and the expired license error no longer exists. The program's "About" screen shows the following, ...

Get the x,y coordinates of the boundaries of countries from the following website Natural Earth (thanks, Devdatta Tengshe) which has more accurate data than others I've tried. Then use ArcGIS 10.2 to open the map shape file and select the boundaries you need. Go to data management tools --features-- features vertices to points and open the generated table. ...

Datum transformation are never fully accurate, which could explain a small shift but not a difference of 30 to 40 m. A difference of 30 to 40 m is more like an error due to the absence of datum transformation, or it could be an error in the dataset that you use for the relative evaluation of your position (Google registration can be wrong in some places of ...

Typical - after spending hours on this, I realised the answer a few minutes after posting the question to Stack Exchange. At least others can learn from my stupidity. I needed to add a 3rd control point, in order to allow the affine transformation to apply the correct adjustment:

I think that might be because there is no single, clear answer. I'll try to summarize my knowledge and the two most related questions: Google earth, google satellite and bing aerial accuracy How accurate are measurements in Google Earth? Let's start by taking Google Earth and even GIS out of the equation and only consider how accurate a measurement on ...

Have a look at Mapillary I think they share the same goals as you and they are making this possible. I have not used it yet (no time) but it looks like a good option to StreetView. The How to Do it is here and it looks like they will make all the data and images available to developers via an api. The quoted terms are: API Usage We allow the use of our ...

The first thing you will want to do is look at the Google Terms of Use and Licensing. Google is very particular on how their data and software can be used. I would look at this first as it may be a show-stopper. The second thing I would consider is that the imagery in Google isn`t raw imagery; they are chips or tiles of data saved in a web tiling format. ...

If you set the project CRS in QGIS to EPSG:32718 (UTM zone 18), you get the same coordinates as reported by Google Earth. You might get different results if you have chosen another CRS. There are several CRS that are called UTM 18S (=South), but only one is based on the WGS84 ellipsoid. The negative Y coordinate looks like a UTM 18N (=North) CRS. For QGIS, ...

You can try ncWMS (http://www.resc.rdg.ac.uk/trac/ncWMS/). This project aims to publish netCDF data as WMS services. Meteorological data on web mapping is always a challenging task due to size and frequency of data available. Solutions will probably involve a mix of server size ...

You can use the Openlayers plugin (http://hub.qgis.org/projects/openlayers/wiki) which introduces OpenStreetMap, Google Maps, and Yahoo Maps as basemaps. See these blogs and youtube videos (http://www.digital-geography.com/qgis-plugins-openlayers/#.VEP5-cnYff0; https://www.youtube.com/watch?v=6N3h4KQW_XQ) for information. Or you can use ESRI's basemapping, ...

That loads two raster layers in Google Earth. I don't think QGIS (through GDAL) supports reading that KMZ (not a KML) because of it. ogrinfo below can't recognize the geometry, even with the libkml (google) driver. ogrinfo -ro -so GMRT.kmz -al ERROR 1: ERROR Parseing kml Style: No id ERROR 1: ERROR Parseing kml Style: No id INFO: Open of `GMRT.kmz' ...

There is some new functionality for kmls in QGIS which I haven't tried. But along your existing skill/workflow, you should try exporting separate kmls and then bring them together in a folder in GE. Firstly select subsets of your data in QGIS based on Soil Type etc. Then Save Selected As Style each of the kmls in GE, then bring them together in a new ...

Rather than linking the two together, why don't you use the OpenLayers plugin which allows you to view Google satellite imagery in QGIS? You can then edit and save your data in Q as a KML (right click save as on your layer) and import into Google Earth if required for fly through's / oblique screenshots etc.
