You can not see oil platforms in oceans because Google Earth shows the underwater terrain (bathymetry). In ocean area you see the seafloor. In land or coast area you see an aerial or satellite image.

There are 60 UTM Zones, each 6 degrees wide (about 700km at the equator), and stretching from 84 degrees North to 80 degrees South (the poles are reference with the Universal Polar Stereographic grid system). So the "UTM Zone" is technically just the number part (eg: 12), a long strip effectively from pole to pole, within which Eastings and Northings are ...

The resolution of imagery in Google Earth varies depending on the source of the data. When you zoom out, you will see the nice, pretty global coverage produced from a mosaic of many Landsat scenes, which have a native resolution of ~30m (~15m pan-sharpened). Zooming in, you'll start to get high-resolution in most places. There are many rural areas ...

There are 2 immediate options that would best get you where you are trying to go. Your first, and probably easiest option, would be to download Quantum GIS, using the OSGeo4W Installer. Once you have installed that program, follow this tutorial, which covers Importing a .csv file to QGIS. Once you have imported the file, simply right click on the layer in ...

As Jens said, Google Earth doesn't show you satellite or aerial images for ocean areas. However, the European Space Agency provides global imagery from its Sentinel 2 mission, which covers the oceans and has a high enough resolution to show oil platforms: Sentinel-2A imagery of Devil's Tower Sentinel-2A imagery of platforms in the Statfjord oil field

The GEOCONTEXT-PROFILER will create an elevation profile just like Google Earth and you can import a KML and export a CSV. It should give you the same results as Google Earth. This is the license restriction page that the tool links to.

As documented on https://developers.google.com/maps/documentation/elevation/start The Elevation API provides elevation data for all locations on the surface of the earth, including depth locations on the ocean floor (which return negative values). https://developers.google.com/maps/documentation/elevation/intro clarifies that Elevation values are ...

Maybe is to late to answer the specific question, but I hope that will help someone else: To identify a platform the historical imagery of Google Earth (GE): Turn ON Layers -> More -> SPOT Image OR DigitalGlobe Coverage. SPOT: from 2010 - series of orange rectangles, possible to click on the icon, you see the relevant information of your scene ...

There are 3 possible reasons what could have happened: There was actually an island at that location, and is not longer present. The possibility of this is remote. This could have been a Copyright Easter egg. This is mis-information that is put in a map, so that when someone copies it, you can use it as a red flag to indicate that copying took place. See ...

One of the most spectacular animated maps I've seen is Google's Wind Map.

The bridge is there both in the image but draped over google earth terrain and as a 3D structure. Turn on 3D building. Note that Google does not allow users to upload their 3D models (previously possible to create and upload with SketchUp a tool now owned by Trimble). The existing 3D buildings and structures have not (YET) been removed, but now new user-...

There is no export to shapefile via Google Earth. These steps when using the Google Earth web version: Once you are in the project section, you can click on the three vertical dots and then export as KML file as mentioned on this thread These steps when using Earth Pro desktop version: You will need to right-click the polygon layer, then click on Save As ...

The heights on google earth refer to EGM96 and are, therefore, Geoidal heights. The lat/long are referred to the WGS 84 ellipsoid.

Both Google Earth and Bing map use data from different sources (satellite images and ortho-photos). The horizontal accuracy depends on the source of the datasets and the level of orthorectification. It is usually better near cities than "in the middle of nowhere", but it primarily depends on the data sources. For instance, some countries have agreements with ...

You have almost the same projection in both map. The difference between them is the CRS's unit. You need to create a custom CRS in Settings / Custom CRS using this proj4 setting: +proj=utm +zone=10 +ellps=GRS80 +towgs84=0,0,0,0,0,0,0 +units=us-ft +no_defs After this, set new CRS in grid layer on properties window: It should work:

To convert UTM coordinates into geographic latitude + longitude coordinates (WGS84), you can use an online tool such as this one. In your case, "30U" means zone 30 in the northern hemisphere, and using this tool, you should get a latitude + longitude of 1.619158, -2.725228. The Z coordinate is mostly irrelevant here as it is just the height in metres above ...

Pro tip... use the measuring tool to draw circles! Google Earth Pro's drawing tools do not include an easy way to draw accurate circles. But, the ruler/measuring tool does let you measure circular areas and save them as KML, so you can do the following to draw a circle: Open measuring tool (ruler icon on toolbar, or Tools menu > Ruler) In Ruler window, ...

Save your money, buy nothing. Associate this script with a toolbox tool. Set it up with 4 parameters (Input Raster, Output Folder, Draw Order and Output Prefix). Run. Tried the SuperOverlay thing from GDAL and didn't think much of that horrible data structure. I never cleaned this up so it does processing it doesn't need to if I remember correctly, but it ...

It is not correct to refer to WGS84 as a 'projection'. Rather it is a datum that is slightly different from a perfect sphere. WGS84 can still be projected onto a Mercator map (as in Google Maps) or a sphere (as in Google Earth). You are simply going between Mercator and spherical. Use the following functions to convert between the two. (in PHP, should be ...

As said in the comments above, the Global Soil Information Facilities (tutorials) website maintained, amongst others, by some of the plotKML authors and contributors gives you everything you need to produce filled polygon areas. In addition to the absolutely correct solution by @Nahm above, here's a reproducible example for future queries on the topic. ## ...

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, ...

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. ...

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 ...

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 ...

The Google Earth Blog (note: this is not officially affiliated with Google) has an article here that might answer your question. It seems that some imagery is added to Google Earth and Google Maps Classic before being added to Google Maps. Edit: I'm unsure if you can point the OpenLayer plugin toward Google Maps Classic rather than Google Maps. Someone else ...

As far as I'm aware, No there is no such feature that performs the actions you are specifically looking for. As a workaround, you could export the layers as KML, import them into My Maps, that will get rid of the folder hierarchy creating a single layer map, and reimporting the custom map to MEL into a new layer. As a step by step here: If you want to ...
