Some of these movies may have been recorded in a previous version of or even in another one of our products, but in these cases the concepts being demonstrated are identical.

Optionally, you can download all of the MicroSurvey CAD/inCAD movies to your computer for offline viewing. For maximum viewing you can press F11 to hide some of your internet browserPress it again to restore the toolbars. Note for Windows x64 users: training movies under Windows XP x64, Windows Vista x64, or Windows 7 x64, you need to ensure you are using a 32-bit web browser. The current Macromedia Flash Player does not function correctly in 64-bit web browsers and in this situation the movies will not play.Puppies For Sale Reading Sliding Bearing Area and FastareaWindow Treatments For Sliding Glass Doors Privacy Swing into a Curve Area and FastareaWasher And Dryer Energy Tax Credit

The most common solution to these problems is to raise the feature geometry by some offset, such as a few meters.  visually acceptable if the viewpoint will remain must higher above the terrain than the offset. 

If the camera is very low, the offset must be small so that the feature does not appear to "float" above the terrain. If the camera is very high, the offset must be large for Z-buffer precision. Some software (such as Google Earth) deals with this by using a dynamic offset, raising the feature geometry as the viewpoint elevation increases.Terrain or elevation data is useful for many GIS Analysis and it is often usedQGIS has good terrain processing capabilities built-in. tutorial, we will work through the steps to generate various products from elevation data such as contours, hillshade etc. Overview of the task The task is to create contours and hillshade map for area around Mt. Everest. Other skills you will learn Searching and downloading freely available terrain data. Exporting a vector layer as KML and viewing it in Google Earth. We will be working with GMTED2010 dataset from USGS. This data can be downloaded from the USGS Earthexplorer site.

Terrain Elevation Data) is a global terrain dataset that is the newer version Here is how to search and download the revelant data from USGS Earthexplorer. Go to the USGS Earthexplorer . tab, search for the place name . Click on the result to select the location. In the tab, expand the group, and check . You can now skip to the tab and see the part of the dataset intersecting your search criteria. You will have to log in to the site at this point. create a free account if you do not have one. Select the option and click . You will now have a file named . distributed in various raster formats such as ASC, BIL, GeoTiff etc. QGIS supports a wide variety of raster formats via the GDAL library. data comes as GeoTiff files which are contained in this zip archive. For convenience, you can download a copy of the data directly from below. Open and browse to the There are many different files generated from different algorithms.

For this tutorial, we will use the file named . You will see the terrain data rendered in the QGIS Canvas. Each pixel in the terrain raster represents the average elevation in meters at that location. The dark pixels represent areas with low altitude and lighter pixels represent areas with high altitude. Let’s find our area of interest. we find that the coordinates for our area of interest - Mt. Everest - is located at the coordinates 27.9881° N, 86.9253° E. Note that QGIS uses the coordinates in (X,Y) format , so you must use the coordinates asPaste these at the bottom of QGIS window where it says and press Enter. The viewport will be centered at this coordinate. To zoom in, Enter in the fieldYou will see the viewport zoom to the area around the We will now crop the raster to this area of interest. The Raster menu in QGIS comes from a core plugin calledIf you do not see the Raster menu, enable the GdalTools plugin from .

See Using Plugins for more details. In the window, name your output file as Keep the window open and switch to the main QGISHold your left mouse button and draw a rectangle covering the full Now back in the window, you will see the coordinates auto-populated from your selection. Make sure the option is checked, and click Once the process finishes, you will see a new layer loaded in QGIS. layer covers only the area around Mt. Everest.Now we are ready to generateSelect the contour tool from . In the dialog, select as theWe will generate contour lines for 100m intervals, so put 100 as the Also check the option so elevation value will be recorded as attribute of each contour line. Once the processing is complete, you will see contour lines loaded into theEach line in this layer represents a particular elevation. points along a countour line in the underlying raster would be at the sameThe closer the lines, the steeper the slope.

contours a bit more. Right click on the contours layer and choose You will see that each line feature has an attribute named . This is the height in metres that each line represents. Click on the column header a couple of times to sort the values in descending order. find the line representing the highest elevation in our data, i.e. Mt. Select the top row, and click on the Switch to the main QGIS window. You will see the selected contour lineThis is the area of the highest elevation in our dataset. Now let us create a hillshade map from the raster. In the dialog, choose asLeave all other options as is. Once the process finishes, you will see yet another raster loaded into QGISSince you maybe zoomed-in near the Mt.Everest region, right click on the layer and choose . Now you will see the full extent of the hillshade raster. You can also visualize your contour layer and verify your analysis by exporting the contours layer as KML and viewing it in Google Earth.
